(100-380 Ton)
Feature
1. The energy saving hydraulic system including fast responding low impact mould movement control, advanced feed back( closed loop) hydraulic control system, it is precise and flexible than other P./Q valve. The German imported valves perfectly match up with its variable pump, ensures high consistence and accuracy. (Flow Response Time 25ms ; Hysteresis Loop 0.3%; Lowest Working Pressure 0.4 Mpa)
2. High injection rate, reduces internal press with high efficiency hydraulic system, which provides outstanding performance.
3. Enlarged clamping stroke to meet with larger stroke requirements.
4. The German imported variable pump with high efficiency return line filter. It saves energy, low noise level, high filtration ability, uses less water cooling and also speeds up cycle time for increasing productivity( Ideal, which could save over 45% power consumption)

2. Drooling and screw back pressure adjustment for high MI index material.
3. Superior injection capability suitable for precision engineering plastic moulding applications
4. Twin injection cylinders ensure smooth and speed setting.
5. Digital two-stages melting pressure and speed setting.
6. Four-stages holding pressure setting.
7. Four-stages injection pressure and speed setting.
8. Injection and holding parameter can be switched over either by time or position.
9. Pivoted injection unit to facilitation change of screw and barrel.
10. Nozzle temperature control.
11. PID digital temperature control.
12. Cold start prevention with Auto Purge function for quick color/material changes
13. Injection malfunction automatic check.
14. Injection screw directly driven by high-torque hydraulic motor with digital speed and pressure control.
15. Plasticizing speed display, it helps the operator to achieve optimal plasticizing result.
16. Manual back pressure control with gauge indication
Hydraulic System
1. The saving Energy Hydraulic System including fast responding low impact mould movement circuit, advanced Rexroth feed back hydraulic control system, which is precise and flexible then other PQ valve. The Rexroth valve perfectly match with its variable pump, ensures high consistence and accuracy.
2. The German imported variable pump with high efficiency return line filter. It saves energy, Low noise level, high filtration ability, uses less water cooling, and also speeds up cycle time for increasing productivity. (Ideally, it could save over 45% power consumption)
3. Temperature and pressure indicator for monitor operation process.
4. Hydraulic and electrical parts are from famous international manufacturer.
5. High efficiency hydraulic system enhances performance.
Clamping Unit
1. Digital four-stage mould closing and three-stage mould opening pressure and speed setting.
2. Heavy-duty 5 points toggle mechanism with same opening stoke, required less motion time , hence increase production rate.
3. Finite Element analysis ensures mechanical rigidity of the clamping mechanism.
4. Computer aided design toggle mechanism gives optimal mould closing and opening speed profile.
5. Hard chrome plated high tensile steel tie bars.
6. Single casting of toggle link on the stationary platen, which enhances rigidity of the clamping unit.
