About LS Mtron Injection Molding Machines

LS Mtron Injection Molding Machines is a division of LS Corporation, a $30 billion USD conglomerate of companies that was founded by South Korean-based tech giant LG Corporation.

LS Mtron IMM was borne out of the Injection Molding Machinery needs of LG Corporation, one of the world’s largest plastic molders, who was producing components used in the manufacturing of LG-brand products.  When LG needed more injection molding machines to keep up with its tremendous demand, they began making machines for their own use.  LG originally produced their own machines using drawings licensed from Toshiba. Eventually, they created the LS Mtron brand which today produces up to 2,800 machines per year, not only for use by its own related companies (LG Electronics

On The Road Of Pioneering Multi-Component Injection Molding Technology, FCS has a promising future




In recent years, multi-component injection molding technology has received increasing attention due to advantages such as high production efficiency, power saving and environmental protection, and high added value of products. It is applicable to a lot of industries, including automobiles, mobile phones, pens, electronic appliances, hand tools, daily necessities, construction, packaging and medical equipment. At the same time, as domestic and foreign companies are also increasing research on multi-component injection molding, new equipment and new technologies emerge one after another. For example, the technology of two-component/multi-component/multi-material/multi-angle injection molding has been developed and has made considerable progress, which has become the focus and hot spot of the injection molding industry in recent years.


Product diversification and differentiation are gradually formed

The advanced two-component injection molding machines developed by FCS include rotary type, rotating shaft type, electric type, sandwich / interval injection molding machine. After the strict test of market customers and actual machine verification,FCS has formed four series covering more than 30 specifications, and the clamping force ranges from 135 tons to 3,300 tons. They are widely applied in a wide range of industries such as automobiles, mobile phones, laptops, pens, hand tools, high-end daily necessities, cosmetics, and home appliances.

Hsiao-Chou Chen, manager of the Technical Department of FCS (Ningbo) Machinery Manufacturing Co., Ltd., said in an interview with Jufeng that the two-component injection molding technology is developed on the basis of the single-component single-material technology. It is the result of market demand for the purpose of replacing manpower with machines and improving the production efficiency of two-component parts and the quality of the combination of different materials. In the past, there were also inlaid metal material molding and twice/three-time molding. The disadvantages of these technologies lie in that they consume a lot of manpower and material resources, occupy production space, and it is difficult to guarantee the quality of recombination after cooling.

Since 2005, due to the emergence of labor, production capacity and mass customization, multi-color and multi-component technology has been vigorously developed in Taiwan. At that time, there were two well-known European manufacturers of injection molding machines in the world with outstanding strength in multi-component and multi-material injection molding technology, but their application field was also limited to the automotive industry, and they did not take multi-component injection molding technology as a key point to develop.

FCS has set the direction of special customized multi-component injection molding machines.As FCS actively explores and develops the technology, it has increased the tonnage of machines from 260 tons to more than 3,000 tons and introduced the modular concept. The clamping mechanism is taken as the core and the injection mechanism is available in the form of a package, which greatly shortens the delivery cycle time and puts forward strict requirements on the Company’s software and design capabilities.

In February 2018, FCS participated in the China Plastics Machinery Industry Association’s Group Standards Working Committee and served as the first company to draft Group Standards of “Multi-component Plastic Injection Molding Machine”. The Group Standards were officially released in the summer of 2020, which was an important milestone in the development of multi-component injection molding technology in China. It ended the chaos of standards by many manufacturers, formed unified standards and even standardized molds, reduced disorderly competition and waste of resources, and brought the development of multi-component injection technology to a new level.

Multi-component injection molding technology has gradually matured, and manufacturers of high-end products such as auto parts have fully accepted the corresponding cost input brought by the application of multi-component injection molding technology. Although temporarily it’s hard for some manufacturers of lower-end products to bear the cost, they will eventually embark on the road of replacing manpower with machines, which is just a matter of time.

In 2015, FCS began to cooperate with Colgate-Palmolive. Four years later, in 2019, the production capacity of more than 300 single-component injection molding machines applied by users before were replaced with the capacity of 22 two-component injection molding machines. The labor force was reduced from more than 6,000 in 2019 to more than 1,100 now. The effect of replacing manpower with machines is immediate and obvious. In addition, a foreign supplier who supplies IKEA, applied one production line of FCS to replace the previous six production lines, creating higher profits for customers with super high price–performance ratio. In the long run

, multi-component and multi-material injection molding technology must be an important direction of the processing and development of the injection molding technology.Not just the concept of plastic will be developed in the future. When plastic and metal powder are injected and molded together, for example, the car lights of BMW electric cars are directly embedded in the bumper for integral molding, eliminating the subsequent installation steps. A type of FCS’s horizontal injection molding machines developed for this application were widely welcomed in the market and became benchmark machines in this field.

When the reporter mentioned the gap between FCS’s multi-component injection molding technology and the international advanced ones, Hsiao-Chou Chen believed that there is almost no gap.The core competitiveness of FCS lies in the ability to quickly adapt to the market and meet the needs of customers, for FCS can provide more models for users to choose and better meet the diversities of molds so that the expandable space is greater.These strengths are not achieved overnight. Instead, FCS has experienced long-term experience accumulation. Special technologies require more technical reserves, and FCS has been striving for them. For example, the integrated car light project, in fact, has been prepared for 10 years. In addition, the equipment developed by FCS now is also actively prepared for the market in the next 5 years or even 10 years. As Hsiao-Chou Chen said, the R&D expenses of FCS accounts for as much as 20% of the Company’s output value, which is unparalleled in the industry. The mission of FCS is: “To lead the development of China’s multi-component injection molding technology, constantly promote the application of multi-component injection molding technology, become the best alternative brand for imported machines and create higher benefits for customers.”

Hsiao-Chou Chen predicted that a major trend in the plastics industry in the future is that there will be more demand for large-scale personalized customization. If expecting to achieve rapid production, the industry needs multi-component injection molding production.It is an inevitable trend to input requirements for different colors and different materials in the front-end computer to change colors and appearance.

The state of full-load production of FCS has lasted for 5 years. In the future, the Company will change the multi-component injection molding technology from the rough type to the more refined and specialized one, and develop the products in the direction of “large-sized and electrified”, to lead the industry to standardization development.

He said that the FCS’s new production base in Hangzhou Bay is prepared for intelligent production of “large-sized and electrified” multi-component injection molding equipment, and has reserved a model factory that will apply 5G technology to organize modern production. On the road of pioneering multi-component injection molding technology, FCS has a promising future

Arburg to have a presence at AM trade fair in Shanghai




From 26 to 28 May, Arburg will be exhibiting at AM trade fair tct Asia 2021 in Shanghai, China. At stand G70 in hall 7.1, the company will showcase the great potential offered by its open system Arburg Plastic Freeforming (APF). Two Freeformers will produce functional parts live, including a two-component closure in a unique material combination of original PP and TPE. Visitors can also expect a wide range of parts, and will be able to test the quality of selected APF parts for themselves at interactive stations.

“The response at Chinaplas in April was very good and showed that everyone is happy that they can again find out about new products and highlights live and in person at trade fairs. Many new projects have also been initiated,” said Zhao Tong, Managing Director of the Arburg organisations in China. “We’re expecting the same from tct 2021 in Shanghai, the big AM event in China. Customers and interested parties will be able to benefit from our comprehensive expertise in plastics processing and meet our experts on site for detailed advice on the potential of our APF process.”

Freeformer 300-3X: resilient flip-top closure

“With two Freeformer exhibits, we will be presenting innovative and sophisticated applications,” explained Wei Yen Lim, APF expert from Arburg China. “Our large Freeformer 300-3X will produce a functional flip-top closure from semi-crystalline PP and elastic TPE at tct Asia 2021. This is a unique and challenging combination of materials in the AM industry.” Prototypes like this with film hinges can be opened and closed several thousand times and can therefore be subjected to full functional testing. The Freeformer 300-3X can process up to three components, thereby enabling the industrial additive manufacturing of complex functional parts in resilient hard/soft combinations with support structure.

Freeformer 200-3X: flame-retardant electronics housing

The second exhibit, a Freeformer 200-3X with two discharge units, will additively manufacture an electronics housing for Hongfa from flame-retardant materials PA6 and ABS. In addition, many part examples will be on display at the Arburg stand and visitors will be able to test the functionality and resilience of various demo parts for themselves at interactive stations.

Know-how in plastics processing

The plastic granules processed in injection moulding can also be used in Arburg Plastic Freeforming (APF). The open system is suitable as well for very soft and certified original materials, and is perfect for demanding applications, for example in medical technology and the automotive industry. The Freeformer is particularly interesting for users who want to produce and test individually customised parts or functional prototypes made from exactly the same material as in large-scale production of the end product. The real added value fully comes into its own when innovative applications, integrated functions, and completely new geometries and designs can be realised additively. In China, Arburg operates a Prototyping Center where Freeformers produce benchmark parts around the clock. This allows potential customers to check exactly which APF process is actually suitable for their desired component
