Injection Molding Machine PSJ-1250

     
1, Clamping Unit: Arrange obliquely five-point and elbow type structure. Optimization design on parameter of the computer. Finite-element analysis is applied to design the plates. The unit also functions of low pressure mold protection with extra sensitivity. Machinery, electric pair of safe protection function to insure the safety;  
                                          
2,

• Oil motor drive the gear to adjusts mold, the moving ahead simultaneously is good and can adjusting the mold automatically according to the pressure set up, very convenient and reliable;

3,Computer Controlled: According imported computer which special for injection machine. The function is powerful and controlled by CPU, improve the speed in control system and the alarm on over-temperature. Improve the working speed of machine;

4,Injection Unit: Double guiding rod supporting. Dual-cylinder balance injection system, Single-Cylinder push and draw back setting. Multi-stage pressure & speed injection. One –string hydraulic motor setting. Super quality steel screw stem mixed with chrome, molybdenum and aluminum and barrel disposed by nitrogen. Suitable for every kinds of plastic raw material;

5,Hydraulic Unit: Adopt imported advance hydraulic components;

6,Storing type on automatic lubricating system of oil;

• With quick response and steady capability, servo gearshift dynamical control system has equipped with pressure feedback device with high precision and sensitivity, which forms a close –loop precision control and provide products with high stability;

7,

• Servo energy saving injection molding machine to achieve the maximum output, in comparison with conventional hydraulic injection molding machines, their response speed have been obviously quickened and cycle time effectively shortened, improving production efficiency;
• There is no extra energy consumption due to output volume changes according to load alteration. The phase of holding pressure, servo motor lowers rotate speed and consumes a little of energies. In the phase of cooling, motor doesn’t work and consumes no energy. According to different products, servo energy –saving injection molding machines will save 20% -80% energy and bring your prominent economic benefit.
