Two-platen machines are the right answer for large molds and high-tonnage production. Chen Hsong’s, developed through more than a decade with Mitsubishi, fits the largest stroke and daylight into the smallest footprint, holds uniform clamping force across a six-figure mold, and still cycles fast.

Two-platen design is well understood across the industry. What sets Chen Hsong’s apart is the engineering behind it. The platform was developed in a long-running partnership with Mitsubishi, drawing on high-end Japanese design for the clamping mechanism, motion profile, and mold-protection logic. That is why these machines deliver precision, stability, speed, and protection together rather than trading one for another.
Chen Hsong pioneered two-platen technology in China in 2007 and built Asia’s first 6,500-tonne servo-driven two-platen machine in 2014.
The advanced design fits the largest stroke and daylight into the smallest floor space. On a crowded shop floor, that saving is real money.
The control platform runs IEC 61131-compliant Beckhoff and B&R controllers over high-speed EtherCAT and POWERLINK buses. Chen Hsong owns the controller IP, so customisation is handled in-house with no third party to wait on.
Clamping reaches 750mm/s, one of the fastest two-platen designs available, keeping cycles short. A patented interlocking mechanism keeps motion quiet and smooth at full speed, and the SVP/3 servo drive cuts energy and cooling-water use by up to 80%.
The fourth-generation servo drive delivers fast response and superior dynamics. Precision Hydraulics™ adds fine motion control for demanding work like injection-compression molding, holding repeatability within ±0.2%. The same high-sensitivity hydraulics handle mold protection.
The platform is modular from the ground up: 13 clamping units and 14 injection units in any workable combination. The largest clamping unit reaches 6,500 tonnes; the largest injection unit carries a 110kg shot. An optional Y-injector adds further combinations.
Chen Hsong introduced two-platen technology to China in 2007 and reached a milestone in 2014 with Asia’s first 6,500-tonne servo-driven two-platen machine.
More than a thousand units are now in production worldwide, including a 3,600-tonne press in Germany. Behind them sits the wider record: over a million Chen Hsong machines installed across nearly 70 years.

Two-platen machines earn their place wherever the mold is large or the part is heavy and floor space is tight. They are the backbone of automotive, appliance, and structural production.
Two-platen machines deliver very high clamping force in a much shorter overall length than a toggle machine of the same tonnage, so they fit large molds into less floor space. They also spread clamping force evenly across a large platen, protecting big molds and improving part quality.
For large parts and high tonnage, two-platen is usually the better fit.
The platform was developed with Mitsubishi, drawing on high-end Japanese design for the clamping mechanism, motion control, and mold protection. It is why the machines achieve precision, stability, speed, and protection together rather than trading one against another.
Up to 6,500 tonnes of clamping force, with the largest injection unit carrying a 110kg shot. Chen Hsong built Asia’s first 6,500-tonne servo-driven two-platen machine in 2014.
The fourth-generation servo drive cuts electricity and cooling-water use by up to 80% versus a conventional fixed-pump hydraulic machine, because the motor draws power on demand and rests when the machine is idle during cooling.
Yes. The platform is modular: 13 clamping units and 14 injection units that combine freely, plus an optional Y-injector setup. Because Chen Hsong owns the controller IP and builds in-house, configuration and customisation are handled directly.
