HAITAI HTW500/JD PLASTIC INJECTION MACHINE
1. SPECIFICATIONS
Advantage: Strong Technical design ability, Stable quality, and large production capability, Famous brand.
HTW/JD servo energy saving Injection Molding Machine, equipped with high performance servo motor controlling system, the machine's output power can vary in accordance with the loading changes,which reduce
energy consumption and noise. The motor rotates at lower speed in holding pressure stage, an doesn't
work in cooling time.
The Performance of servo energy-saving molding machine:
- Servo motor can optimize the match of energy demand and realize automatic adjustments.
- It can improve injection precision
- It can greatly save power and water, resulting in environment-protection and energy-saving
- Quick response and low noise.

3.Production description
CONTROL SYSTEM
All-digital control system uses dedicated controller, multiple CPU processing division, a multi-functional automatic fault detection, alarm system, certificates 99 mold of processing procedures, with remote control interface. System is of high stability and responsiveness. System uses color LCD, man made interface for easy operation and with a number of peripheral interfaces.
FEATURES
- A variety of text can be switched.
- Manual, semi-automatic and fully automatic mode.
- To provide EUROMAP robot interface.
- Automatic movement monitoring with alarm and fault diagnosis.
- Function of slope setting can set the start and stop of movements, so as ensure the smooth movement

HYDRAULIC SYSTEM
Advanced hydraulic system design, through proportional control of pressure, flow achieves rapid multi-level pressure, speed switching, the system configuration is reasonable, stable and reliable. The noise is less than 75 dB. The medium and large machine adopts a two way cartridge inserted valve system to improve the system of flow and speed of response, and makes the whole machine reach the best performance.

CLAMPING SYSTEM
- Security doors fitted with hydraulic, mechanical and electrical interlocking triple safety device. When the safety door is open, the machine cannot clamp.
- Low pressure mold protection device to prevent damage to platen.
- Plywood, frame, the bridge, and the template attached structure, the finite element analysis.
- Hydraulic ejector, adjustable stroke, and top speed of ejector in and out, for multiple actions.
- Flexible tie bars nut eliminates fatigue fracture; assure the working life of tie bars
- Automatic adjustment. The replacement of different mold, the parameters set by clamping force to achieve the automatic adjustment.
- High-precision electronic detection device, multi-stage control of opening stoke, speed and location, location accuracy.
