Vertical Injection Air Over Oil Cylinder Machine


Vertical Injection Air Over Oil Cylinder Machine

  •   Intuitive touch screen operation.

  •   Air over oil cylinder gives large clamping forcefor larger part.

  •   LPMS specially designed melt-on-demand tank can melt down the resin swiftly and evenly.

  •   The gear pump is made of hard-wearing materialwhich is stableinjection volume accuracy ±0.1gmaximum shot size is 5.8g/s.

  •   Injection pressure range 1~50kg, which can be controlled by the pneumatic safety valve. LPMS also have option like electronic safety valve, which means the injection pressure can be set more precisely from the PLC.

  •   Three thermal control zones for precise melt control.

  •   Equipped with light curtain and dual palm buttons for operator safety.

  •   Mechanical ejection system and control for pneumatic ejection.


       LPMS® machines are engineered for low pressure molding, using specialty resins to encapsulate delicate parts, like automotive electronics, PCBA, coil, fiber-optic, LED lighting, cable, etc.

       The benefit of vertical injection is that when smaller parts allow the cavity to be split into two or four cavities. This allows shorter runners and higher output per cycle. It’s suitable for multiple cavity mold for cable, wire harness, LED, etc.
