Introduction
Der-Hsin Plastic Machinery is a Taiwanese manufacturer of plastic processing equipment, with a focus on injection molding machines, extrusion systems, and related automation solutions. The company has operated for several decades, producing equipment that serves a broad range of industries including automotive, consumer electronics, medical devices, and packaging. Der‑Hsin’s product portfolio is characterized by a combination of high precision engineering, robust build quality, and a commitment to meeting international standards for safety and environmental performance.
History and Background
Founding and Early Years
The company was established in 1974 in Taichung, Taiwan, by founders Liu Chang‑chi and Chang Wen‑hao. The initial focus was on producing small to medium‑sized injection molding machines for local manufacturers. Early models incorporated manually operated screw drives and basic temperature control systems. The rapid industrial growth of Taiwan during the 1980s created a demand for domestic production equipment, allowing Der‑Hsin to secure a foothold in the national market.
Expansion into Automation
In the 1990s, Der‑Hsin introduced a line of semi‑automatic injection molding machines, integrating programmable logic controllers (PLCs) and operator interfaces. The shift toward automation was driven by client demands for higher throughput and consistency. The company invested in in‑house research laboratories to develop proprietary thermal management systems and improved hydraulic designs.
Global Reach and Modernization
By the early 2000s, Der‑Hsin had begun exporting to neighboring Asian markets, establishing distribution centers in Hong Kong and Singapore. The company completed a comprehensive modernization program in 2010, upgrading manufacturing lines to ISO 9001 certification standards and adopting lean production methodologies. In 2015, a joint venture was formed with a German automation firm, allowing Der‑Hsin to incorporate advanced robotics into its machine designs.
Key Concepts in Product Design
Precision Injection Molding
Der‑Hsin’s machines employ dual‑screw extrusion heads that provide uniform melt temperatures and reduced cycle times. The design incorporates high‑tolerance injection ports and low‑friction roller beds to ensure dimensional accuracy. Temperature control is achieved through an array of heat exchangers and embedded sensors, enabling precise maintenance of melt and mold temperatures within ±0.5 °C.
Energy Efficiency
Energy consumption is mitigated through the use of variable frequency drives (VFDs) on all hydraulic and electric components. The company reports average energy savings of 12 % compared to standard industry models. Additionally, regenerative braking systems capture kinetic energy during machine shutdowns, redirecting it back to the grid or local process lines.
Safety and Compliance
All Der‑Hsin machines are engineered to comply with IEC 60204‑1 and ISO 13849 safety standards. The machines feature emergency stop buttons, interlocked safety cages, and redundant fail‑safe pressure monitoring systems. The company maintains an extensive documentation package for each product, including safety certificates and user manuals in multiple languages.
Applications
