MK7max

The Stability Upgrade.

The MK7max is built for general-purpose production where weight consistency, dimensional accuracy, and long-run stability matter most. Proportional valve mold motion control and servo-driven flow and pressure deliver weight repeatability below 3‰ and mold opening accuracy within ±0.2mm. Dual-loop thermal control holds process temperature stable across long production runs, reducing between-shift drift and the operator interventions that come with it.

Available in 12 models from 88 to 668 tonnes, with patented high-strength platens, a linear guide injection unit, a chrome-plated mixing screw, and closed-loop oil temperature monitoring all standard. Specifications that exceed comparable machines in their class accommodate larger molds and complex, variable production orders. The MK7max is well suited for automotive components, home appliances, daily necessities, as well as mixed-order environments that require frequent mold changes.

FAQ

01What Industries Is the MK7max Best Suited For?

The MK7max is designed for general-purpose production where weight consistency and dimensional accuracy matter shot after shot, including automotive components, home appliances, and daily necessities.

Its broad mold compatibility also suits mixed-order environments with varying product types and frequent mold changes. The measurable precision (<3‰ weight, ±0.2mm opening) makes it effective for parts where tolerance drift between shifts has historically been a yield problem.

Yes. The 12-inch touchscreen controller has built-in IoT connectivity and integrates with the iChen™ Smart Family, including iChen Smart Factory, iChen Cloud, and iChen AI Molder, for production monitoring, process optimization, and factory-wide data integration.

The MK7max is the MK7 family’s stability-focused flagship.

It shares the proven MK6max premium hardware platform, including patented platens, linear guide injection, and high-rigidity frame, and adds upgraded control: proportional valve mold motion, dual-loop thermal, closed-loop oil temperature monitoring, and measurable precision specs (<3‰, ±0.2mm).

The MK7S is a different choice within the MK7 family, built around e-Drive™ electric plasticising as standard for energy-conscious production.

Choose the MK7max when stability and precision drive your decision; choose the MK7S when energy savings and smart e-Drive efficiency matter most.
