SUPER HIGH PRECISION Exclusive for this MK6 range is the new proprietary servo pressure regulation technology. This unique technology ensures fast pressure relief while never reversing the pump. High precision linear transducers are used for the clamping, injection and ejector axes. All results in low- pressure mold protection.
BECKHOFF X-MOLD CONTROL APPLICATION The XMold controller of Beckhoff offers an integrated solution for the automation of the Chen Hsong Injection Molding machines. High-speed applications and complete production cells can be implemented with XMold. The integrated eXtreme Fast Control technology enables the sampling of rapidly changing input signals, allowing the injection process to be controlled with high precision. The 12,1 “ screen area with touch function enables a clear process visualization.
HIGH PERFORMANCE AND VERSATILE SCREW DESIGN More than 20 years of Japanese expertise is used for the development of the screws for this MK6 series. They are available for several process requirements (f.e. PVC screw, PC barrier screw) and for high demand mixing requirements (high mixing barrier screw).
ENERGY SAVING With speed controlled servomotor, drives a fixed internal gear pump. The system pressure is measured real-time by a pressure sensor. In this way it can provide the required flow according the requirement to eliminate non-functioning consumption. In total this leads to lower energy consumption, high precision, low noise and low inertia.
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.
Major Advantages of JM-MK6 Machines:
Low Energy Consumption:
High efficient Servo motors reducing energy consumption up to 80%, bringing high precision and super low noise operation.
Production Flexibility:
Larger space between tie bars (tie rods clearance), maximized storks bringing molders the ability of production with various molds.
Redesigned Platen:
Redesigned platen providing better distribution of clamping stress, lighter and faster operation and longer life.
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.
Better Performance:
Injection unit based on the bearing guides, providing better performance, absorbing of stress and even operation of the injection dual cylinders.
Faster Cycle Times:
High pressure injection and fast speed recovery save seconds on cycle time.
Ergonomic well designed safety doors and covers maximizing the room for operation and maintenance.
Low maintenance requirement, repeatable and reliable production.
