The MK6.6/SI+ is engineered as a true all-rounder. One machine that handles diverse molds, materials, and applications without compromise. Patented high-strength platens with thickened centres deliver just 0.156mm deformation under load (vs 0.205mm and 0.238mm on competing 160T machines), producing uniform clamping force and better mold protection.
A Japanese-engineered toggle with hand-fitted motion profile runs smoothly at high speed. Precision Hydraulics™ minimises pressure fluctuations for stable output every cycle, and Intelligent Auto Clamp Adjustment holds clamping force within ±5% with no operator intervention.
In real-world benchmarks (LED lighting part, 8-cavity PC mold, 121g shot), the JM168-MK6.6/SI+ achieves 3.4x higher part weight CPK, 1.7x higher wall thickness CPK, and 3.8x higher clamp open CMK than competing machines, with a 13% faster dry cycle and 15% higher speed. Now expanded to 12 models from 88 to 1000 tonnes, three injection unit sizes per frame, with a light mixing screw as standard and bimetallic or PVC-spec options for engineering and corrosive resins.
Backed by a 98% customer repeat-order rate across the MK6.6 platform. Choose the MK6.6/SI+ when one machine has to handle varied molds and materials, and quality consistency, mold protection, and operating cost all need to hold up across long production runs.
The MK6.6 platform serves multiple markets with regional configurations: the MK6.6 Euroseries for Europe, the MK6.6/B Brilliance and MK6.6/A Artisan for Asia, the MK6.6/SI Superior India for India, and the MK6.6/D for the Chinese domestic market (each available on Chen Hsong’s regional sites).
The MK6.6/SI+ Série International is the latest-generation export variant of the platform, with the tonnage range expanded to 88–1000T (vs 88–658T on earlier MK6.6 variants), a refreshed light mixing screw standard, bimetallic and PVC-spec screw options, and the current Intelligent Auto Clamp Adjustment system.
All MK6.6 variants share the same patented high-strength platens, Japanese-engineered toggle, and Precision Hydraulics™.
Different priorities, different machines. The MK6 PRO is the injection precision flagship (±0.15% closed-loop accuracy, 31% higher CPK on demanding tolerances).
The MK7max is the stability flagship with measurable mold-motion specs (<3‰ weight repeatability, ±0.2mm opening). The MK7S is the smart and energy flagship (standard e-Drive™ electric plasticising, 15″ AI-assisted controller, up to 1850T).
The MK6.6/SI+ is the production-proven all-rounder, with wide application adaptability backed by 3.4x weight CPK and 3.8x clamp CMK against competition. Choose SI+ for broad mold and material flexibility with proven CPK numbers; choose PRO, MK7max, or MK7S when their specific specialisations match your priority.
The MK6.6/SI+ is proven across automotive components, optics, electronics, toys, medical consumables, and home appliances. The combination of patented high-strength platens, Japanese-engineered toggle, and Intelligent Auto Clamp Adjustment makes it especially effective for production environments where one machine has to handle varied molds and materials without compromising on consistency.
Yes. The MK6.6/SI+ connects to Chen Hsong’s Mega Cloud platform for Industry 4.0 remote monitoring, diagnostics, and networked productivity, and integrates with the iChen™ Smart Family (iChen Smart Factory, iChen Cloud, iChen AI Molder) for production monitoring, process optimisation, and factory-wide data integration.
The 12″ smart touchscreen controller supports MES interface and existing factory systems through standard communication protocols.
EUROMAP and SPI mold standards. B&R, KEBA, and Beckhoff controller options available by region. Local service support in 85+ countries.
