The new Jetmaster C series, proudly presented by the Chen Hsong Group in the year of 2002, was designed with general plastic moulders in mind. Jetmaster C series features enhanced stability and excellent performance, and is a reliable and cost-effective solution to all moulders.
Newly-designed circular platen, with improved stress distribution, is cosmetically appealing and guaranteed for ten years*.
Five-point toggle design enhances stability and reduces clamping movement time.
Advanced high-efficiency, energy-saving hydraulic systems. Reduction in electricity consumption up to 40%** is possible.
*Under correct use and normal circumstances, free of charge maintenance up to ten years for first-hand owner.
**Subject to different product applications and cycle times. Energy-saving device is an optional feature.
Standard Features
Nitride injection screw and barrel.
High tensile steel tie bars with hard chrome plated surface.
Standard vane pump.
Automatic mould thickness adjustment function.
Injection unit
Five-stage injection speed and seven-stage injection pressure.
Computerised temperature control with accuracy ±1°C.
High torque hydraulic motor with 99-step speed control.
Self-lubricating bushes are used in injection screw and tie bars for smooth running. Contamination of machine surface and moulded part is avoided as no external lubrication is needed.
Decompression device to prevent nozzle from drooling.
Cold start prevention with low temperature alarm prevents damage to the injection screw caused by insufficient plasticisation temperature.
PID barrel temperature control with auto-tuning functions.
Automatic detection of blocked nozzle and material overflow.
Exclusive Circular Platen (patented)
Awarded Utility Model Patent Certificate ZL 01 2 57876.2.
The design consists of a base plate with center circular hole, 4 guiding holes, 1 inner circular shape reinforced structure at the back of the base, reinforced wedges in between the inner and outer reinforced structure. The outer reinforced structure is characteristically in either circular shape or oval shape building on top of the base plate.
Circular platen streamlines the stress distribution field, reduces stress concentration and prolongs its lifetime.
Circular platen could satisfy the predefined safety factor requirement, and comes with additional advantages of material saving, higher stiffness and better strength. Suitable for all injection moulding machines.
Clamping Unit
Tie bars are made of Japanese imported high tensile steel with enhanced stiffness, hard chrome plated surface and enlarged tie bar diameter to guarantee durability.
Robust in-house manufactured spheroidal graphite cast iron platens minimize platen deformation and guarantee durability.
Multi-stage clamping speed and pressure control.
Fast clamping movement saves up to 70% of time.
Automatic setting of high pressure clamping position.
Hydraulic multiple ejecting device.
Central electric fixed dosing lubrication system.
Electric lubrication system.
Adjustable speed and pressure control of ejector and vibrating ejector function. Ejector does not need to retract fully during vibration in order to reduce cycle time.
Japanese imported alloy bushes are used for clamping toggle to replace traditional steel brushes.
Movable platen using self-lubricated bushing, reduces chance of contamination on plastic parts.
Energy Saving Device
German or Japanese made hydraulic devices reduce electricity consumption from 10% to 40%**, when compared with standard vane pump.
Energy lost and system heat-up are minimized as the pump supplies flow and pressure according to the actual demand. Lower oil temperature reduces expenses in cooling devices.
When used with larger capacity pump, the opening/clamping speed, injection speed and ejection speed can be increased by 20% or above.
CPC-2.2 Computer Controller
Manufactured in Japan with Chinese instruction
Five-stage injection speed and seven-stage injection pressure for precision moulding.
Enhanced memory capable of storing 150 sets of mould information, e.g. time, counting times, speed, pressure, stroke, quantity, mould thickness, description of mould number, conditions for selection and barrel temperature.
Data lock function prevents unauthorized access and mistaken amendments.
Self-diagnostics functions will display faulty areas with more than 80 causes and remedies.
Status of input, output, time and injection count are monitored.
Adjustable speed and pressure control of ejector and vibrating ejector.
Barrel temperature is controlled by auto tuning PID with the use of precision AD converter and K type thermocouple.
Mould data can be copied or deleted easily to save setting time. A variety of standard mould data settings are also readily available.
