Mark 6 Series

High Performance, Energy Efficient Injection Molding Machines

Stability & Performance

The MK6 represents the 6th generation of JETMASTER Series Servo Drive injection molding machines. Clamping mechanism, machine base, and injection unit have been significantly enhanced and strengthened to achieve superior efficiency and overall stability.

Precision – Energy Efficient

MK6-series machines employ SVP/3 servo-hydraulic technology that typically delivers 80% energy savings on average compared to older fixed displacement machines.
Precision HydraulicsTM realises repeatability within 0.05% in critical movement axes, helping clients increase their productivity and products’ acceptance rate.

80% Energy Saving

Case study

TTI Group jumped from 90% to 98.8% acceptance rate, CH machines have proven themselves to be more competitive.

Major Advantages of JM-MK6 Machines

  • 1

    Low Energy Consumption:

    High efficient Servo motors reducing energy consumption up to 80%, bringing high precision and super low noise operation.

  • 2

    Production Flexibility:

    Larger space between tie bars (tie rods clearance), maximized storks bringing molders the ability of production with various molds.

  • 3

    Redesigned Platen:

    Redesigned platen providing better distribution of clamping stress, lighter and faster operation and longer life.

  • 4

    Faster Mold Setup:

    Redesigned Ejector system providing the SPI standard and plenty of room to work with the ejector rods, which allows faster mold setup than ever.

  • 5

    Better Performance:

    Injection unit based on the bearing guides, providing better performance, absorbing of stress and even operation of the injection dual cylinders.

  • 6

    Faster Cycle Times:

    High pressure injection and fast speed recovery save seconds on cycle time.

  • 7

    Ergonomic well designed safety doors and covers maximizing the room for operation and maintenance.

  • 8

    Low maintenance requirement, repeatable and reliable production.
