SI - Superior India

Tailored specifically to Indian industrial needs, the Mk6.6/SI-“SI” standing for “Superior India”-is a new jewel in Chen Hsong’s crown. It’s the product of more than three decades of our meticulous work in India, a testament to our deep understanding of the region’s unique needs and priorities. This machine is much more than a tool; it’s a tailor-made solution, crafted to perfectly fit the Indian manufacturing landscape.

MK6.6/SI Servo-Driven Injection Machines

Tailored specifically to Indian industrial needs

The Mk6.6/SI leverages 65 years of Chen Hsong’s pioneering experience in injection moulding, honed by the latest technological advancements and merged seamlessly with proprietary Japanese Precision Hydraulics™ technology. The outcome is an equipment capable of silky smooth, high-speed motion, setting new industry benchmarks for speed, stability, and reliability.

The ‘SI’ series’ key feature is its precision linear guideway in the injection unit. This innovation boosts moulding accuracy, cuts cycle times, improves load management, and augments rigidity, while reducing maintenance demands. Altogether, it significantly enhances performance and reliability.

Patented High Strength Platens

Low platen deformation

Low platen deformation ensures high part quality and superior mould protection.
The centre of both platens is thickened to achieve lower deformation, and thus more uniform clamping force on the mould, than most competitive offerings.
