With over six decades of experience in the industry, Chen Hsong Group is one of the most well-known manufacturers of horizontal injection molding machines in the Asia-Pacific region, with a stocked portfolio of products ranging from 30 to 6,500 tonnes.
Chen Hsong Sales Manager Victor Chang said that compared with top-notch companies from Japan, Chen Hsong’s product prices are more competitive by at least half, providing customers with the best price-performance ratio.
With a relatively limited market in Taiwan, Chen Hsong has focused chiefly on broadening its oversea markets. It has turned its turnkey service to plan and construct factories for clients to become a lynchpin to the company’s global presence.
Chen Hsong recognized that having local agents is not enough, as agents commonly represent multiple companies simultaneously and could face a possible shortage of storage on crucial equipment.
The company decided to establish branches where it has agents, not to fight them for the market, but to support the agents’ efforts to provide better services, as well as provide on-site customer service and faster responses to satisfying equipment requests for clients.
Aware of the mounting environmental concern, Chen Hsong said over the past 15 years, it has begun installing servo motors and developing all-electric powered machines to help reduce the carbon footprint of its machines.
Chen Hsong’s array of servo motor-powered and all-electric machines, with sizes between 180 and 1,200 tonnes, ensures that the company can meet the rising market demand for multicolored product designs while improving production efficiency.
Injecting different colored materials into the same mold from two or three nozzles simultaneously, Chen Hsong creates a net decrease in material waste. At the same time, the servo motor allows the company to maintain a precision of power output.
Using energy-efficient servo motors also prevents equipment error and wastes energy. In addition, adopting machinery results in more power efficiency and decreased overhead.
The company says that servo motor-powered machines are still 50 percent more energy efficient than traditional machines but cannot reasonably compare with all-electric machines.
The memorandum of Understanding (MOU) with Mitsubishi Heavy Industries in 2011 hailed the two company’s collaboration on the SM SPARK All-electric injection molding machine and two-platen servo-hydraulic machines.
Built with a servo motor to control and execute repetitive motions, the SM SPARK efficiently shortens molding cycle time.
“Chen Hsong’s all-electric machines can manufacture light, thin, short and small products while retaining high-speed manufacturing and high-pressure packing capabilities,” Chang said.
Chang also clarified that its all-electric machines are not limited to such products. They could also manufacture products such as convex lenses for scanning purposes, low-pixel digital cameras or car headlights.
According to Cheng Hsong Sales Director Aaron Chao, “Mitsubishi Heavy Industries’ proficiency in machine structure design, structure streamlining, and structure reinforcing has nudged us towards a new research and development (R&D) direction. For example, its products have improved both in aesthetics and quality.”
In addition to the all-electric molding machine, Chen Hsong’s two-platen molding machine was one of the significant collaborations with Mitsubishi.
Chen Hsong said that its 1,000-tonne two-platen machine could support up to 1,800 to 2,000 tonnes in retooling processes. In addition, the design to insert casts from the side is a great boon, allowing factory owners to save space otherwise necessary for overhead cranes to lift the product above machine-level and drop it onto the machine. As a result, a growing number of factory owners are switching over to two-platen devices.
Chen Hsong is becoming increasingly familiar with the two-platen machine's mechanics, hydraulics, and electrical system as it assembles two-platen machines for Mitsubishi Heavy Industries’ in its China-based factories.
“Chen Hsong is the most significant exporter of the two-platen machines in Taiwan,” Chao said.
Chen Hsong is no slacker in keeping up with the trend of Industry 4.0. It understands that many clients are using the pretext of machinery upgrades to induct the Industry 4.0 concept into their factories to increase production efficiency.
“How to help clients achieve Industry 4.0” is the issue that Chen Hsong’s industrial Internet of Things solutions hope to resolve.
As a solution, Chen Hsong’s machinery, including the all-electric SM SPARK and others, can be interconnected through the Industrial Internet of Things (IIoT) via pre-installed sensors, which visualize equipment settings and parameters for the user.
The images can be saved for later analysis, positively benefitting product yield rate and stability. Most importantly, the connectivity of Chen Hsong’s machines helps realize the company’s goals of building a smart factory.
While electronic controls of older types of machinery pose the biggest obstacles for integration into a more modern system, Chen Hsong is confident that its engineering team can adapt the controls for machines across all brands built within the past 20 years.
If such an act is impossible, Chen Hsong would collect parameters from 50-100 machines and feed the data through its software to analyze the best possible solution.
Chen Hsong has also integrated its IIoT into Cloud, increasing response speeds on system abnormalities or optimization requests. As a result, Chen Hsong engineers can access equipment data stored on the cloud network and provide troubleshooting or equipment maintenance in the shortest time possible.
“Chen Hsong has a stocked portfolio of services and products that can be delivered to its clients, regardless of their business type or regulations in their respective countries,” Chang said
About Chen Hsong
The Chen Hsong Group, established in 1958 by renowned philanthropist and industrialist Dr. Chen Chiang, has been devoted to manufacturing mold injectors for the past six decades. With an annual sales figure of 20,000 units, Chen Hsong is one of the largest mold injector manufacturers worldwide, and its production and service centers take up a total of 800,000m2 of space worldwide.
Chen Hsong’s research and development team has been leading the trends, delivering the Mk6/TSV/SPEED Double Toggle Machine, the HVC Hydraulic Clamping Machine, the DVC Dual Color Machine, the DPV Dual Platen Machine that I have collaborated with Japan’s Mitsubishi Heavy Industry, as well as the new generation of the SPARK all-electric machine, which sees applied uses in all kinds of industries. Its products, from the smallest of 30 tonnes to appliances weighing 6,500 tonnes, come in all sizes.
Chen Hsong’s employees’ adaptability and flexibility, especially in the manufacturing department, have grown with the company’s diversification and customization of machinery. The company itself had implemented measures, such as records of product quality coming from workstations, taking note of personal and group production efficiency, and plugging such information into monthly considerations for bonuses or punitive measures.
Chen Hsong is proud of its teams, which see an increase in production efficiency year-on-year.
