HJF-290 injection molding machine
Some of the important features:
Clamping system: Faster response, stable and high rigidity
Injection system: Accurate and flexible, lower rejection rate
Control system: Computer and simple operation, molding data memory system
Power system: Energy saving, high efficient and precise
Metal parts: The thickness of our frame, metal plate and wallboard are thicker than other company.
Adjustment Unit
Automatic mold height adjustment saves the time and cost during the mold changing.
Clamping Unit
The plates were designed using FEM software,ensuring a stable and rigid clamping system.Five point inward moving double toggle system ensures high rigidity and precision for mould clamping and also reducing stress and strain effects.
Hydraulic Unit
The hydraulic system using the world famous pump and control valve can control the machine running precisely,ensuring the precision,reliability and durability of whole machine.
Injection Unit
Dual-pillar supporting and dual-cylinder injection balance devices ensure the stress on screw balanced during injection.Specific screw and barrel designs are available for processing different material requirements.
