Vertical Injection Single Working Station Compact Machine

LPMS 800

Vertical Injection Single Working Station Compact Machine

  • Intuitive touch screen operation.

  • 7 liter melting tank integrated into machine.

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

  • Linear scale it’s precise for mold clamping, does not need to adjust the reed switch position.

  • The gear pump is made of hard-wearing material,which is stable,injection volume accuracy ±0.1g,maximum shot size is 5g/s.

  • Injection pressure range 1~50kg, which is controlled by 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. 

  • Over temperature alarming and automatic heating stop functions.

  • 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.
