UV Spray Painting

UV coating, UV Spray painting, or ultraviolet coating, is a very glossy, shiny liquid coating applied to a printed paper or plastic surface and cured on a printing press or special machine using ultraviolet light. The coating hardens, or cures when it is exposed to the ultra-violet radiation.

Plastic is used in almost every industry, from aerospace innovation and 3D printing to electronics, medical equipment’s and product packaging. Many applications benefit from the advantages that coatings provide such as wear resistance, insulation, chemical resistance and improved performance – but plastic presents unique challenges such as,

  • Heat Sensitive Plastics
  • Adhesion
  • Low Energy Substrate
  • Sensitivity to Solvents

Advantages of UV Coating for Plastics:

There are several reasons opting for custom UV coating service is the best decision for manufacturing:

  • Scratch Resistance
  • Dependable Chemical resistance
  • Less Curing Time, which eventually results in better production efficiency
  • Versatility in Colour and Finish Options
  • Better Product performance in Harsh Environments
  • Environment Friendly Solution

Electronics manufacturers use UV coatings to ensure durability and functionality of smaller plastic parts, while the automobile industry relies on UV Coatings on plastic components to have ideal appearance, scratch resistance and better functionality over the years.

All these major performance benefits of UV Coating typically also result in lower production costs compared to other coating options, making UV coating for plastic a cost-effective solution. When it comes to packaging, the excellent adhesion to plastics, visibility of product information on thermoplastic bags and other storage containers is vital for tracking purposes, quality assurance and customer satisfaction makes UV coating an ideal solution for it.

In addition to plastic polymers, UV coatings can be done on wooden surfaces and an endless amount of other industrial surfaces as stated below:

  • Paper
  • Glass
  • Fabric
  • Concrete
  • Metal

Plastics are of different types and each have their own unique characteristics and the proposed application plays a huge role in deciding the plastic material and coating requirement for to suit the application.

Turret Punch Press in Sheet Metal Fabrication

In this article we will review another important machine frequently used in sheet metal fabrication, that is the Turret punch. Turret punch (also known as a turret press) is a high-speed press machine equipped with a variety of standard punch tools. These tools cater for a wide range of hole shapes and sizes.  

CNC Turret punch machines are equipped with two turrets and each housing a set of punches and dies. In most machines, each turret is able to hold at least 40 different toolsets.  

The term “turret” refers to the holders which can be precisely programmed to rotate and load the required punch and die. Through its advanced control system, both turrets can be configured to move and rotate in sync to any specific position. 

The turret punch machine simulates the typical blanking or piercing process of a standard press machine for the relatively small and standard shapes. Whereas for much bigger and complex shapes, it is done by incrementally “punching” the shape of the material. In other words, instead of “punching” all the holes and shapes in a single shot, the turret punch machine utilises its advanced control system to precisely fabricate the metal parts in a series of high-speed strokes.  

So why not just stick to conventional press machine? 

As opposed to the standard press machine, turret punch eliminates the need for a high cost investment in product-specific tooling. Capitalising on its wide range of tool shapes and features, turret punch addresses these cost-related constraints that are commonly faced by manufacturers particularly for low-volume products.  

What about laser cut? Isn’t it more flexible than turret? 

When determining the best process for a low-volume product, manufacturers often consider between laser cut and turret punch as each have their own strengths and weaknesses.  

What about laser cut? Isn’t it more flexible than turret? 

When determining the best process for a low-volume product, manufacturers often consider between laser cut and turret punch as each have their own strengths and weaknesses.  

But when it comes to profiles with repeating straight-forward shapes and holes, turret punch is the obvious winner. Without the need to deal with additional costs in laser gases, ventilation and maintenance, turret punch supersedes the laser cut process through its high-speed punching mechanism and low setup cost. Not to mention that turret punch eliminates the risk of thermal distortion in thin material sheet due to laser heat exposure. 

As an experience manufacturer in high-precision sheet metal fabrication, we strive to the deliver the best services and solutions to our customers. Our in-house turret punch is capable of: 

  • Punching capacity: 30 ton 
  • Max sheet size: 1525x3050mm 
  • Max thickness: 6.35mm 
  • Nibbling speed: 600 hits/min 
  • Number of tool stations: 40 
  • Max ram stroke distance: 31mm 
  • Punching accuracy: +/- 0.1mm 

Sourcing Injection Moulding & Metal Fabrication service outside of China

If your company is in need of plastic injection molding or metal fabrication services, it’s hard to avoid the Chinese market. China is currently the largest producer and exporter of injection molds and plastics in the world. With more than 15,000 plastic factories, it accounts for nearly a third of the global plastics production. China also leads the world as a producer of steel and other metals. These resources power it’s massive iron and steel fabrication industries.

But with the US placing hefty tariffs on China’s steel and aluminum, and the growing uncertainty surrounding the on-going trade war between these two economic power-houses, many companies are sourcing their injection molding and metal fabrication services outside of China.

The truth is, while China may dominate the headlines, there are other regions in Asia that companies can turn to for their plastics and metal production. Developing economies such as Vietnam, Malaysia and the Philippines have been investing heavily in cutting edge technologies and infrastructure to become serious alternatives to China in the world market.

But like China, it’s neither quick nor easy to set up a profitable partnership in these regions. You need to know what to look for in a manufacturer and have a plan in place to take care of issues such as quality control and compliance with local regulations. This added bit of due diligence can make all the difference between successfully developing and manufacturing your plastic or metal products versus wasting countless time, money, and other resources working with the wrong manufacturer.

That said, if you are looking for injection molding and metal fabrication services in Vietnam, Malaysia or other regions in Asia outside of China, then here are several steps you can take to have the best chance of finding the most suitable and reliable companies:

The first step in the sourcing process is to develop a list of manufacturers in the region that could potentially be a good fit for your product. This means you need to be clear about your needs, and answer questions like:

Step 1: Build a List of Manufacturers

• Will you need help with product development?
• How big will your production runs be on average?
• How quick does the turn around time need to be?
• How specialized are the parts or items that need to be produced?
• How important is it that people at the factory know how to speak English?

Once you know what you are looking for you can begin your search. To do this, use trustworthy B2B directories, look through trade catalogs or conduct a search online. You can also tap your network for referrals and attend trade shows.

As an aside, when searching online, pay close attention to the manufacturer’s website. Look at details, such as whether the site is professionally designed and easily to follow, the quality of the English, and finally, what qualifications or references are listed. All of these details can provide important clues about the kind of company you are looking at.

Step 2: Contact the Manufacturers on Your List

In this step, the goal is to narrow down the list of potential manufacturers by reaching out to them and making some basic inquiries. The first thing to note is if the company has English-speaking contacts, such as sales representatives and product managers.

If your company is in need of specialized, non-commodity product, then an initial discussion about product specs and technical needs can reveal whether or not the manufacturer can handle certain specifications and adjustments. You should also ask about their manufacturing process, equipment, and request product samples.

Step 3: Further Investigate Qualified Manufacturers

After narrowing down your list of serious candidates, it is absolutely essential that you take the process a step further. At this stage you will be doing your due diligence by conducting a full background check. This includes gathering and evaluating several critical sources of information such as:

• References from non-Asian clients
• Asking local contacts about the company’s reputation or sending someone to the factory to check out the work conditions and equipment
• Requesting copies of standard industry certifications like ISO or Good Manufacturing Practices

All of this added screening will help to ensure that you are only considering legitimate companies that are in the best position to fulfill your needs.

Step 4: Visit the Factory

At this point, you should have no more than two-to-four qualified and reputable candidates that have demonstrated the ability to produce your product to your specifications at the cost you are looking for. Now it is time for a face-to-face meeting. Treat this part of the process as an opportunity see for yourself the factory’s conditions and potentially begin to develop a business relationship. You should be looking for chemistry between your team and theirs as well as professionalism.

Travel restrictions limiting factory visits? Try asking for a conference call or online audit! You can also engage third party audit companies to perform system audits as well.

After completing the four steps above, you should have all of the information you need to make an informed decision about where to source your plastic injection molding or metal fabrication services. In the end, you may be pleasantly surprised by the options available to you outside of China.

Malaysia: your manufacturing destination in Southeast Asia

Is your manufacturing disrupted by COVID-19 or trade war? Ever considered Malaysia as your manufacturing destination in Southeast Asia?

To mark the 63th Independence Day (or in Malaysian, “Hari Merdeka”) from British rule, we bring to you some points on why Malaysia should be your next manufacturing destination in Asia. We wrote about Manufacturing in Malaysia some two years back, and everything still holds true today.

Today we share more on Malaysia and it’s trading relationship with the rest of the world.

Manufacturing destination Malaysia

Malaysia: always a trading nation, even before its inception

For a few hundred years, the strategic location of Malaysia (today) has always been heavily influnced by trade from east to west and vice-versa. Key to this is the Straits of Malacca, The World Economic Forum has called it the second busiest waterway and one of the most important. These straits act as a natural chokepoint for shipping traffic between the Far East and the Old World. This natural chokepoint means the ports in the region are some of the world’s busiest.

Before the inception of Malaysia, various Sultans ruled the land and was heavily involved in trading. The Straits of Malacca, has brought people of many nations together for hundred of years. Hence today, Malaysia is home to a population of 32 million multi-ethnic, multi-lingual and multi-skilled people. In many cases, people can speak some combination of English, Malay, Mandarin or Tamil, so communication isn’t an issue for international customers.

International trade is an important driver of the Malaysian economy. Malaysia imports and exports a large amount of goods (and services) and in that regard, has signed many bilateral and multilateral trade agreements.

Manufacturing destination in Southeast Asia

By its membership in ASEAN (Association of Southeast Asian Nation), Malaysia is able to trade with all Southeast Asian countries through the ASEAN Free Trade Agreement (AFTA). This allows all ASEAN countries to trade amongst each other without tariffs. AFTA’s objective is clear:- To create a global manufacturing base comparable to the Far East in South East Asia. AFTA has made many ASEAN countries like Malaysia the manufacturing destination of choice for customers worldwide.

Trade agreements

As a trading nation, Malaysia hasn’t shied away from signing numerous trade agreements. Malaysia has Free Trade Agreements (FTA) signed with other countries directly (and indirectly through its ASEAN membership). Malaysia is always looking to sign more trade agreements and is in negotiations with more countries / region for FTA. Malaysia has been a member of the WTO since its creation in 1995.

Malaysia, having a small domestic economy, relies heavily on international trade. Open trade, fair foreign investment regime and effective governance are some key policies that the Malaysian government adopts. Naturally, Malaysia does also have its competitive advantage to be part of the global supply chain. Malaysia is rich in natural resources and hence key source of raw materials for global industries.

Access to raw materials

Malaysia has a thriving oil & gas industry and has numerous agricultural produce like palm oil. Historically Malaysia has relied on rich and boyant upstream activities, but since independence development has focused on mid & downstream activities, e.g. semi-processed goods and in recent decades, high-tech electronics. These advantanges mean that certain material can be procured with better leadtimes and cost. Having a developed petrochemical industry for example, means Malaysian companies can access plastic resin locally.

Becoming a manufacturing destination of choice does not happen overnight. Malaysia has for years been on a journey to develop itself and be part of the global value chain (GVC) by developing downstream activities like processing and manufacturing. The corrosponding supply chain network and supporting industry and systems is a result of years of investments and technological development leading to its maturity today.

Leading in electronics & medical devices manufacturing today

Malaysia has been the manufacturing destination to many well-known brands for many years. This has created competitive advantages as certain niche and supply chain network is established. Today, approx 25% of Malaysian GDP is driven by manufacturing. Industrialization started as soon as Malaysia achieved independence, and further accelerated in the 1970s/80s with supportive government policies to attract multi-national global brands.

Most raw materials, parts and components can be imported into Malaysia without any issues, as Malaysia has good trading relationship with all major nations.

Manufacturing destination in Southeast Asia

Malaysia also ranks high for ease of doing business, political stablility and transparency. This makes it the perfect destination for companies choosing the next manufacturing hub, whether to set up shop or to select a manufacturing partner.

Sourcing Outside China: the Pros and the Cons

Sourcing outside China to minimize your supply chain risks? In these uncertain times, as the need for supply chain diversification and efficiency increases, businesses may be wondering sourcing outside of China, to another country will actually lead to lower risk, reduced costs and a well oiled supply chain.

By all accounts, China is the largest manufacturing economy in the world for low-cost goods previously, and more recently, for advanced, high-end products, such as electronics and technological products. In fact, according to a recent report published by the United Nations, China accounted for 28 percent of the global manufacturing output in 2018. When this is coupled with seemingly limitless supply of labor, a modern infrastructure and the region’s rich supply of a wide range of precious resources, it seems as though manufacturing China is a no-brainer.

Sourcing outside China: an important step to minimize supply chain risks

Supply Chain Disruption

But, rising labor costs across most large Chinese cities, increased tariffs and instability within the global market are making manufacturers consider other economies. US President Trump’s 25% tariff on imported Chinese goods, for example, has raised manufacturing costs for American companies to the point where it is prohibitive. This has left them scrambling for alternatives.

But, leaving China is not a step that buyers and procurement managers can take lightly. Moving manufacturing to a new country can be a great way to improve stability, total cost of ownership or quality but it also requires careful planning and consideration. Each country has its own legislative reality and way of doing business, and some regions are just better than others for producing certain products.

That said many emerging economies promise to be the next China– if even a mini version of it. But, they too have their advantages and downsides to consider.

The top alternatives to China currently include Malaysia, Vietnam, India, Bangladesh, Indonesia, and Thailand.

Both Malaysia & Vietnam for, example, has a growing, modern infrastructure, relatively low manufacturing costs, and is close enough to China to benefit from its resources and infrastructure. It also has a high level of industry diversity plus a willingness among factories to work with smaller product runs. Finally, for US companies, shipping lines run frequently, resulting in ease of importation of goods.

But even with all of these qualities, both Malaysia & Vietnam just can’t compete with the size and scope of the Chinese economic juggernaut.

So where does this leave companies looking for a change in their supply chain?

When deciding what road to take, businesses should be aware of the major pros and cons to moving production out of China in the first place.

Why Keep China in the Supply Chain

Even with the above drawbacks, there are still several reasons why companies may choose to stay in China:

  • Taking advantage of the extensive infrastructure. China has been in the manufacturing game for many years now, and they have invested a lot of resources into building up their internal infrastructure. This includes the largest shipping and supplier network in Asia.
  • Access to raw materials. One of the biggest hurdles for businesses wanting to move their manufacturing outside of China is access to necessary raw materials. Few to no countries can compete with China’s resource-rich environment. Plus, with a network of almost 3 million factories operating operating throughout the country, manufacturers can easily get all the material and supplies they need from a nearby factory without having to import it from another country.
  • Cheap labor still exists. It may be harder to find, but it’s possible to keep labor costs low by choosing to work with a factory located in a more rural area in China. However, companies need to be concern if it is too good to be true as there are instances of human rights abuses.
  • A new market opportunity. China isn’t just a manufacturing hub, for some companies it can also be a potential market for their products. With a population of over 1.3 billion people, that’s a lot of potential customers. Breaking in to this market, however, requires the help of a locally-based outsourcing company.

Reasons to Source Outside of China

Here is a rundown of the majors reasons to move manufacturing out of China:

  • Lower production costs. One of the major advantages to working outside of China is that production costs can be dramatically lower– especially when it comes to large production runs. This has a touch of irony since the primary driver to manufacturing in China has always been the ability to tap into an exceptionally large labor-ready force earning below average wages. But labor costs in China have risen dramatically over the past 20 years or so.
  • Fewer regulations. Though the Chinese government has many regulations and incentives in place to help keep local companies competitive, there are a number of strict requirements and limitations for foreign companies doing business there. Many neighboring countries on the other hand, have more favorable business environments for foreign entities.
  • Reduce risk. The on-going trade war between China and the US, and by extension, much of the world, creates a lot of uncertainty about what the future holds for China and its manufacturing industry. Such uncertainty just doesn’t fit in a supply chain that must quickly adapt to changes in demand. Many smaller companies in particular may find that they need a more stable and predictable environment.

The bottom line for companies wishing to move their manufacturing outside of China is that they need to be in touch with their needs and go into the process informed. Alternatives to China are definitely out there, but every company has to decide what makes the most sense for their products and business model.

Metal Fabrication using the CNC Press Brake Machine and Its Advantages

Understanding Press Brake in Metal Fabrication

Press Brake is an important process in any metal fabrication manufacturing. Press brake machine as the name suggests, is a pressing machine commonly used with a set of punch and dies to fabricate various types of sheet metal. Categorised by its means of exerting force, there are several types of press brakes that include, mechanical, pneumatic, hydraulic and servo-electric. Nowadays, due to the advancement of hydraulics and control system, hydraulic press brake machines are currently the most opted for in the sheet metal industry.  

Metal fabrication press brake

The basic parameters that governs a press brake machine are the force or tonnage and its working length. The machine’s working height, stroke length, distance to the back-gauge and crowning are the additional control parameters. Back in the days prior to the development of complex control systems, these parameters required an experienced and highly skilled operator to manually set and tune based on the product requirements. 

Why use a Computer-Numerical-Control (CNC) Press Brake in metal fabrication? 

  1. High Flexibility, Low Setup Time – On top of its ability to automate and integrate with advanced robotic bending system, CNC press brake machines offer high flexibility with low setup times. Taking advantage of its immaculate control systems of the back-gauge distance, bend angle and stroke length, the control systems can be used to register and record the type of bends and its required setup parameters, enabling the setup of multiple bends using the same machine. Essentially a product be formed from a flat sheet metal to its final shape just from a single setup.  
  2. Advanced Crowning System – Greater Consistency and Repeatability – Also known as the ‘kayak or canoe effect’, this is a condition that commonly occurs in high-tonnage press brake applications. The term ‘kayak’ refers to the deflection of the beams and table during the press sequence. Crowning is a fine-tuning process required to offset and equally distribute the forces of the press brake. Instead of using shims or grinding the bar to manually offset the deflection, the system compensates this effect by measuring the deflection and generating the opposite forces or “curve” necessary to ensure that the ram and table are parallel during bending. This allows for a consistent bend angle along the products bend line. What was previously an intricate and time-consuming process, are now simplified allowing for greater consistency and accuracy. 

Our sheet metal fabrication capabilities: we have 10 press brake machines

Currently we have a total 10 press brake machines with 4 of them being CNC press brakes. Combined with our years of experience in process, fixtures and tooling design, we serve a wide range of high-precision sheet metal fabrication services at a competitive pricing. A glimpse of our bending capabilities includes: 

  • Maximum machine tonnage of 110 tons 
  • Bending length of up to 3000mm (122 inches) 
  • Material thickness ranging from 0.3mm to 6mm (0.012-0.25 inches) 
  • Complex forming: lower tooling cost and quicker turnaround 
  • Bending tolerance of up to +/- 0.25mm

CMT Welding in Metal Fabrication and How Is It Similar to MIG Welding?

We explore the differences of MIG Welding (Metal Inert Gas) and CMT Welding (Cold Metal Transfer) and how it is used in metal fabrication process.

What is Welding?

Welding can be defined as a metal fabrication process that utilises high heat to melt and join materials, commonly metals or thermoplastics together. In other words, it is basically a joining process that involve the manipulation of material phase from solid to liquid and back to solid. Welding technology has long been and is constantly evolving. It is no surprise that nowadays there are numerous welding methods currently being applied in the industry.

MIG Welding in Metal Fabrication

In MIG Welding, the workpiece and the welding gun are part of the same electrical circuit. The electrode wire is automatically fed through the gun. Current instantaneously flow the moment the electrode wire touches the workpiece. As the electrode wire rapidly heats up due to the high amperage, the tip of the solid electrode begins to melt into metal droplets.

The metal droplets would then separate from the electrode forming an electrical arc that is around 3500°C which heats up and melts the workpiece forming a molten puddle. This enable the metal droplets to fuse with the base metal. As the temperature decreases, the molten puddle of base material and metal droplets solidify, forming weld beads. This process continuously repeats itself several times each second until the seams are fully welded.

CMT Welding in Metal Fabrication

The differences in CMT and MIG welding process is fairly subtle with the exception in the way the electrode wire is fed.

In contrast to continuously feeding the electrode wire into the molten puddle (MIG), in CMT, the electrode wire is instantly retracted the moment current flows. This provides the welding some time to cool before each drop is placed. In doing so, this process leaves a smooth weld that is way stronger than the hotter weld (MIG).

These steps are repeated throughout the welding process. Obviously, this requires a lot of sophisticated control technology which is why it is commonly performed using a welding robot.

Enabling the welding some time to cool means that this welding process can be carried out at a lower temperature. Thus, reducing the risks of heat-related defects from occurring in the welded materials. Through the usage of robotic arms and advanced control system, welding can be carried out at high-speed precision and consistency.

Why use CMT Welding in Metal Fabrication?

There are tremendous advantages in opting to use CMT for your products that include:

  • The ability of CMT to weld materials at a lower temperature can be leveraged to mitigate heat-related defects such as, material warpage and the oil-canning effect.
  • Works well with thin metals that are prone to warping.
  • Allows the welding of dissimilar metals (eg: steel and aluminium) through its controlled metal disposition and low heat-input.
  • Automated process, means greater speed, precision and consistency in products.
