Dimensionally unstable reason analysis of injection molding products

Epluser Co.,Limited | Updated: Sep 25, 2015

1. Machine

(1) the plasticizing capacity of plasticizing capacity large machine should be used.

(2) the feed instability, should check whether the machine voltage fluctuations, injection system hydraulic valve components for wear or have any questions.

(3) screw speed instability, should check whether the motor is faulty, screw and barrel wear, hydraulic valve is stuck, the voltage is stable.

(4) the temperature control, proportional valves, pressure valves are not working properly, the back pressure instability.

2. Mold:

(1) must have sufficient strength and rigidity of the mould cavity materials, wear-resistant materials to be used.

(2) dimensional accuracy is very high, try not to use a multi-cavity form.

(3) the ejection system, injection system, cooling system to set reasonable and ensure stable production conditions.

3. Plastics:

(1) new material mixed with recycled materials to be consistent.

(2) dry conditions should be consistent particles should be uniform.

(3) fully into account when the material shrinkage effects on dimensional accuracy.
