HJF-780 injection molding machine with servo
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.
Electronically Controlled Unit
1. CPU controller and display are independent and reliable.
2. A larger color LCD screen enhances clear display and support multi-language compatibility.
3. The control system also support remote monitor.In the event of a control problems,the machine can be connected to internet through a special interface.Inject service can realize remote fault diagnosis and maintenance.
4. A screen saver function extends the LCD life.
5. Ultra bright LED is provided for input and output point inspection.Proving convenient indication of the machine’s operation and machine service.
6. A data hardware lock is provided to prevent unauthorized people from effecting the machines performance.
7. Closed loop PID barrel temperature control.
8. Dust and waterproof control cabinets provide a neat and tidy enclosure all electric control components.
