The DM III is Chen Hsong’s third-generation multi-material injection molding machine with toggle clamping, backed by 25 years of rotary platen innovation since pioneering the industry’s first servo-driven rotary platen in 1997. 4 patented technologies protect mold alignment, platen stability, ejection precision, and injection accuracy. Servo-driven rotary platen delivers ±0.005° positional accuracy with clearance of 0.15mm or less, more than twice the precision of industry average.
Modular injection system with 5 configuration types (piggyback, vertical, lateral, on-mold, horizontal parallel) for flexible multi-material production from 168 to 568 tonnes. eDrive servo plasticising standard for 30% higher efficiency. Digitally-controlled precision injection with ±0.2% accuracy. Aerogel barrel insulation reduces energy loss by 28%. Built for automotive tail lights, consumer electronics, medical devices, power tools, toothbrushes, and any application where two or more materials meet in a single part.
Both share the same 4 patented rotary platen technologies, modular injection system, and servo-driven rotary platen with ±0.005° positional accuracy. The DM III uses toggle clamping from 168 to 568 tonnes.
The DMZ III uses two-platen clamping from 550 to 750 tonnes with a patented locking mechanism, larger mold space, and reduced machine height. Choose the DM III for standard multi-material production. Choose the DMZ III for larger parts requiring higher clamping force or bigger mold space.
Patent 1: Rotary Platen Clamping Device (ZL 2022 2 1048581.2) prevents platen tilt for uniform force distribution and extended mold life.
Patent 2: Rotary Platen Support Device (ZL 2023 2 2478460.2) with eccentric fine-tuning stays firm and prevents loosening.
Patent 3: Rotary Platen Ejection Device (ZL 2023 2 2478456.6) uses a spring-loaded friction ring to reduce friction during rotation.
Patent 4: Injection Cylinder Device (ZL 2023 2 2478463.6) enables linear injection without rotational movement, eliminating oil leakage points that plague competitor systems.
The DM III is designed for two-colour, two-material, and multi-component injection molding applications: automotive tail lights and interior trim, consumer electronics housings, power tool grips, toothbrushes, medical device components, household products, and toys.
Any application where multiple materials or colours must bond seamlessly in a single molding cycle.
The DM III uses servo motor control with optical encoder feedback for high-speed rotary table positioning. Unlike competitors that use hydraulic motors with mechanical stoppers, the DM III’s servo system delivers precise and repeatable positioning unaffected by power outages or component rotation.
This eliminates the positioning inaccuracies and stopper impact issues common in hydraulic rotary table systems, resulting in higher product quality and easier process control.
Yes. The DM III supports multi-component injection molding with 3 or more materials as an option. Three-station and four-station turntable configurations are available.
The modular injection system allows multiple auxiliary injection units to be added in various positions (piggyback, vertical, lateral, on-mold, horizontal parallel).
Chen Hsong provides installation, training, maintenance, and technical support through more than 120 service locations worldwide.
The DM III is supported by dedicated multi-material specialist teams with expertise in rotary platen systems and multi-component process optimisation.
EUROMAP and SPI mold standards. B&R, KEBA, and Beckhoff controller options available by region. Local service support in 85+ countries.
