Smart Efficiency. Built In.

The MK7S is Chen Hsong’s latest-generation toggle platform, designed from the ground up around eDrive™ electric plasticising and intelligent control. Every model comes with eDrive™ as standard, reducing energy consumption by 10 to 25% while enabling simultaneous plasticising during mold open/close for shorter cycles across the board. 

12 models from 88 to 668 tonnes, a 15” smart controller on every machine, bimetallic screw and barrel as standard, and aerogel barrel insulation reducing heating power by 28%. The MK7S brings together energy savings, faster recovery, and smart production intelligence in a single platform ready for automotive, electronics, medical, home appliance, and general-purpose manufacturing.

FAQ

01 How Does The MK7S Compare To The MK6 PRO?

The MK6 PRO is positioned for maximum injection precision and performance (31% higher CPK, ±0.15% injection accuracy). The MK7S is positioned for smart, energy-efficient all-round production with eDrive™ as standard on every model.

If your priority is the tightest tolerances on demanding parts, the MK6 PRO is the choice. If you want built-in energy savings, faster recovery, and intelligent control across a wider range of applications, the MK7S is the platform.

eDrive™ is Chen Hsong’s electric plasticising system. Instead of using the hydraulic motor for screw recovery, an electric servo motor handles plasticising independently.

This reduces power consumption by up to 30% during plasticising, increases recovery speed by up to 30%, and enables simultaneous plasticising during mold open/close when paired with valve gates or a shut-off nozzle. On the MK7S, eDrive™ is standard, not optional.

The MK7S is proven across automotive, home appliances, 3C electronics, medical, daily necessities, and toys.

Its combination of energy efficiency, faster cycles, and smart control makes it effective for both general-purpose production and more demanding applications requiring consistent quality.

Yes. The MK7S integrates with the iChen™ Smart Family including iChen Smart Factory, iChen Cloud, and iChen AI Molder. The 15” smart controller supports production monitoring, process optimization, and factory-wide data integration.

Chen Hsong provides installation, training, maintenance, and technical support through more than 120 service locations worldwide. Regional offices in Europe, North America, South America, India, Southeast Asia, and China ensure local response and long-term operational support.
