The MK6.6 is Chen Hsong’s sixth-generation servo-hydraulic toggle platform, built around three engineering decisions that drive part quality and operating cost across every variant in the family.
Patented high-strength platens with thickened centres reduce deformation to just 0.156mm under load (vs 0.205mm and 0.238mm on competing 160T machines), producing uniform clamping force across the mold face.
A Japanese-engineered toggle with hand-fitted motion-control profile runs smoothly at high speed without vibration. Precision Hydraulics™ keeps pressure stable cycle after cycle, with low-pressure mold protection built in.
The MK6.6 is available in 12 models from 88 to 1000 tonnes, with three injection unit sizes per frame. Multiple regional configurations are produced for specific markets: the MK6.6 Euroseries for Europe (B&R SmartMold 9 controller, Bosch Rexroth hydraulics, EUROMAP interfaces), the MK6.6/B Brilliance and MK6.6/A Artisan for Asia, the MK6.6/SI Superior India for the Indian market, and the MK6.6/D for the Chinese domestic market.
For international export and the latest-generation specification, the MK6.6/SI+ Série International is available globally with refreshed light mixing screw, bimetallic and PVC-spec screw options, and the current Intelligent Auto Clamp Adjustment system. Backed by a 98% customer repeat-order rate across the platform.
Choose the regional variant that matches your market, or the MK6.6/SI+ if you’re buying for international export.
The MK6.6 is Chen Hsong’s sixth-generation servo-hydraulic toggle injection molding platform. It defines the core engineering for every variant in the family: patented high-strength platens with thickened centres (0.156mm deformation at 160T), a Japanese-engineered toggle with hand-fitted motion profile, and Precision Hydraulics™ servo-hydraulic drive.
The platform covers 88 to 1000 tonnes across 12 models with three injection unit sizes per frame, and is produced in multiple regional variants tailored to local controller, mold standard, and electrical specifications.
The right variant depends on where you operate. The MK6.6 Euroseries serves European factories with B&R SmartMold 9 controller, Bosch Rexroth hydraulics, and EUROMAP interfaces. The MK6.6/B Brilliance and MK6.6/A Artisan serve Asian markets through Chen Hsong Vietnam. The MK6.6/SI Superior India is built for Indian manufacturing conditions.
The MK6.6/D is the general-purpose workhorse for the Chinese domestic market. For international export and the latest-generation specification (refreshed mixing screw, Intelligent Auto Clamp Adjustment, and the broadest current tonnage range up to 1000T), the MK6.6/SI+ Série International is available globally.
Visit your regional Chen Hsong site for the right variant for your local market, or see the MK6.6/SI+ page for international export.
Each MK6 family machine owns a different lane. The MK6 Standard is the proven base workhorse with the broadest installed base (over 1 million machines worldwide) and Precision Hydraulics™ at ±0.05% repeatability.
The MK6.6 adds the patented high-strength platens and Japanese-engineered toggle as the speed-and-stability upgrade. The MK6 PRO is the injection precision flagship (±0.15% closed-loop accuracy, 31% higher CPK on demanding tolerances).
In the MK7 family: the MK7max is the stability flagship with measurable mold-motion specs (<3‰ weight repeatability, ±0.2mm opening), and the MK7S is the smart and energy flagship with standard e-Drive™ electric plasticising and 15″ AI-assisted controller.
The MK6.6 platform is proven across automotive components, optics, electronics, toys, medical consumables, and home appliances. The patented platen technology and Japanese-engineered toggle make it particularly effective for production environments where consistent clamping force and mold protection matter shot after shot.
Yes. All MK6.6 variants integrate with Chen Hsong’s iChen™ Smart Family (iChen Smart Factory, iChen Cloud, iChen AI Molder) for production monitoring, process optimisation, and factory-wide data integration.
Connectivity through standard communication protocols supports MES, MOM, and other smart manufacturing systems already in place on the factory floor.
EUROMAP and SPI mold standards. B&R, KEBA, and Beckhoff controller options available by region. Local service support in 85+ countries.
