CLAMPING PART:
We creates independently the box type high rigidity mold structure for the clamping part; the clamping support guide rail adopts the high rigidity design to reduce the deformation effectively; the toggle structure optimized and designed with computer achieves exceptionally stable and rapid clamping; and the enlarged mold thickness, the gear mold regulation unit and the internally installed mechanical safety lock as well as the 180-degree rotary product blanking bucket, all help achieve your individual demands and make your operation easier!
Box-type mold platen design, strong and durable. 
High quality copper bushes on tie bars guiding parts, working life long.
Push platen adopts the self-lubrication copper bushes, long life, high speed & precision.
Thicken central of platen, effective for mold and machine life and product precision.
Enhanced strength for fixed platen, improve products stability and quality.
Special designed machine base, clamping unit supported by the base girder, ensure machine base perfect balance, and few deformation after long time working.
Full supported injection base, avoid it up and down during high pressure injection.
High quality SKD61 screw tip, check ring and thrust ring, 38CrMoAl screw and barrel.
Self-lubrication bushes ensure high repeatability precision and long life.
Centralized lubrication for injection unit, easy for feeding lubrication grease.
Chimney exhaust designed nozzle purge guard, suitable for clean-plant production.
Barrel PID controls the difference of temperature less error.
Hydraulic Unit
The oil way design of big bore under no resistance can lower the oil way loss and noise; it uses the advanced configuration, the servo control system, so it features energy saving capacity up to 20-80% and can achieve zero back pressure glue-smelting with plasticizing capacity and plasticizing effect improved by 60% compared with the traditional machine; and it uses a high density filtering unit in order to control the greasy dirt at NASB-9.
World famous brands hydraulic parts ensure machine’s stability and fast response.
Visible and dischargeable oil tank, easy for hydraulic circuit maintenance.
Adopt modular adaptor valve blocks, come true change different drive system easier.
SELF-SEAL magnetic suction filter, make your maintenance more convenient. 
Pump oil suction port and oil tank oil outlet placed at same side, easy for maintenance.
Germany DIN standard hydraulic pipe fits with seal, ensure no leaking.
