What are the characteristics of precision plastic injection molding machine?
The precision injection molding machine for injection molding of plastic products is called precision injection molding machine.For example, some instruments and mechanical parts with special requirements are required to be within the range of 0.01 ~ 0.005mm in structural dimensions. Generally, it is difficult to achieve precision in the molding of general injection molding machines.
The structural characteristics of precision injection molding machine are as follows.
The working face of the cylinder and screw used for plasticizing injection should be specially hardened to improve the hardness and wear resistance.
The screw structure should be suitable for the material with strong plasticizing ability, large driving torque and stepless speed control.
In order to adapt to high injection pressure (the injection pressure is between 220 and 250MPa), each part of the injection molding machine assembly should have better working strength and rigidity.
Low pressure protection adjusting device and clamping force adjusting device should be equipped at the parts where the die is formed.
