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
, LG Appliances, LS Automotive, LG Solar, etc.), but for many other molders around the world.
LS Mtron machines are premium quality, manufactured in supply-chain friendly South Korea. LS maintains total control over manufacturing its machines by leveraging the tremendous power of its founding company, LG Corporation, and its related spin-offs. This includes using Korean-made steel from an LS subsidiary, servo motors made by an LG-founded company, and more, including the ability to ship through another LG-related company, LX Pantos. This helps LS Mtron conquer the long lead times many others experience. When building a new molding machine, LS Mtron can achieve castings to cargo ready in about 100 days.
In the USA, LS Mtron Injection Molding Machines is led by Peter Gardner, Business Director. The company’s US headquarters are in Peachtree Corners, GA (near Atlanta), and its Tech Center is in Wood Dale, IL (near Chicago).
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
, material, or application before considering a purchase.
Best practice: Hauff relies on cube technology
Lossburg, 3 May 2021
“By professionals, for professionals – turnkey means: quality from a single source.” That was the title of the fourth arburgXvision broadcast, which hit screens on 29 April 2021. Andreas Reich, a turnkey expert with responsibility for Business Development Sales, joined Bernd Eble, Senior Application Manager Cube Mould Technology, to provide fascinating insights into the world of automation, turnkey applications and cube-mould technology. More than 400 viewers tuned in live to the interactive Arburg TV broadcast online. Two links provided a direct, exclusive look at the assembly process in Lossburg and at the company Hermann Hauff, which has been using an Allrounder Cube to produce challenging two-component injection moulded parts.
The broadcast focused on using customised turnkey systems, intelligent automation concepts and innovative cube technology to fully exploit the potential inherent in injection moulding production.
The majority of the German viewers (27 percent) came from the automotive industry, while around 40 percent of the international participants were involved in medical technology. 11 percent of the German audience and 20 percent of the international audience were part of the packaging sector. 86 percent of the German poll participants and 71 percent of those internationally said they were already working with automated injection moulding machines. The respondents primarily cited increased productivity and personnel matters as drivers of automation in their own companies. Towards the end of the broadcast, 40 percent of the German audience and 66 percent of the international viewers said that cube technology was a subject of significant interest to their business.
Huge potential in customised turnkey systems
Andreas Reich put forward his belief that “over the long term, every injection moulding project is set to become automated – no matter where in the world it is”. Among the reasons he listed for this were the high output quantities that are in demand and the increasing integration of production steps such as stamping inserts and assessing product quality. As a primary contractor, he said, Arburg offers custom-automated turnkey systems from a single source and draws on some 25 years of experience plus a whole host of expert partners. In Germany, every second machine that Arburg supplies already comes with an integrated robotic system.
“Machines that can be configured with modules and accompanying robotic systems with uniform operational systems are an essential part of developing alternative concepts for solutions”, stressed the turnkey expert, going on to state that the kind of system expertise Arburg delivers stands out because of its ability to examine the injection mould and the process in detail. The earlier Arburg is able to become involved in and provide input on the design of a product, he said, the more harmoniously the machine, mould and automation are able to work together. He used the example of a car body to highlight a range of manufacturing concepts and explained that, even though an investment involving full automation may cost three times as much, it will still pay for itself after just two years or so.
Insights into Arburg project management
A live link with Lossburg provided an exclusive glimpse behind the scenes, with an assembly test bench being used to illustrate how Arburg brings this kind of turnkey system to life. Andreas Armbruster, head of the Automation & Turnkey Solutions department at Arburg, demonstrated the commissioning of a production cell for a PCB housing and the simple programming process involved in an integrated six-axis robot. He also showcased a networked smart turnkey system that produced drinking cups and performed inline finishing on them live. Thanks to two DM codes and the Arburg Turnkey Control Module (ATCM), each individual cup can be traced and linked to a digital product passport for recycling purposes. “We look forward to every new project that comes our way and are always delighted to help customers breathe life into them”, concluded Andreas Armbruster with a smile.
Allrounder Cube for even more productivity
In addition to the machine itself, the mould technology has a significant impact on the efficiency of a production cell and the unit costs. Bernd Eble expressed his firm belief that “cube technology is boosting productivity dramatically, in every industry”. As an example, he talked about the mass production of two-component snap closures for washing-up liquid bottles – items that are high-tech but need to cost next to nothing. “Our Cube series features outstanding productivity with a small footprint, making it suitable not only for packaging products, but also for the cycle time-neutral addition of inserts, assembly of single components and automated part removal.” Bernd Eble also provided an in-depth explanation of how cube technology works and the potential it holds, highlighting a three-component Allrounder 4600 Cube equipped with a Foboha 24-cavity cube mould and a six-axis robot. This production cell is able to replace four standard systems in a compact unit.
Hermann Hauff relies on innovative cube technology
The second link of the broadcast focused on a unique reverse cube application in use at Hermann Hauff GmbH & Co. KG in Pforzheim, Germany. Jörg Vetter, the company’s Head of Technology, explained how Hermann Hauff is using this innovative cube technology in a in a cost-effective process that produces two-component rollers for the lower baskets found in dishwashers. In the future, the company plans to produce as many as 65 million of these each year. In this application, the Allrounder Cube is being used as a substitute for four standard injection moulding machines and three assembly systems.
Knowing what it takes
“Customer requirements are becoming increasingly complex and the demand for automation and digitalisation is rising all the time. Accommodating this means using customised, smart turnkey systems and a central control system that provides an easy, transparent way of operating everything. If cycle times can be cut down as a result of this, and the user experience and product quality can be made better, then the investment costs will pay for themselves in hardly any time at all”, said Andreas Reich in the final panel discussion with host Guido Marschall. Not only that, he said, but integrated robotic systems are enabling more synchronisation between machines, moulds and automation. Customers who already have experience of turnkey solutions and newcomers alike will both receive a warm welcome from Arburg, and can both benefit from improved cycle times and lower manufacturing costs. Bernd Eble expressed another important insight: “Our projects allows us to become involved in a lot of different areas, and since we’re consistently working with mould technology, that means we have developed an extensive stock of knowledge that we can transfer to all kinds of industries. Our automation solutions and new technologies keep our customers competitive and ensure they are fit for the future.”
Next arburgXvision broadcast on 27 May 2021
The next edition of arburgXvision will take place on Thursday, 27 May 2021. With “Savings through hidden benefits!” providing the title this time, the fifth broadcast will focus on production efficiency. Christoph Kiefer, Team Manager Technical & Commercial Sales Support, and Dr Thomas Walther, Head of Application & Process Development, will provide viewers with first-hand insights into the hidden benefits they can use to optimise their injection moulding production and lower costs as a result. There will also be two live links to the Arburg Customer Center to accompany the broadcast.
