On the equipment side: the top output is not enough.
Second mold aspect
(1) The demoulding structure is unreasonable or improperly positioned.
(2) The draft is not sufficient.
(3) The mold temperature is too high or the ventilation is poor.
(4) The surface of the sprue wall or cavity is rough.
(5) The nozzle does not conform to the feed port of the mold or the diameter of the nozzle is larger than the diameter of the feed port.
Three aspects of the process
(1) The barrel temperature is too high or the injection volume is too much.
(2) The injection pressure is too high or the pressure is maintained and the cooling time is long.
Four raw materials: insufficient lubricant.
The traditional mold release methods for plastic molded parts are roughly classified into four types: top, push, draw, and spin.
There is now a new release technology that can easily solve the problem of plastic release. In the plastic mold industry, in particular, it is necessary to use a variety of resin compounds for highly complex design, and there are many unsolvable problems in the appearance of high gloss finishing.
The nano-release coating can form a coating on the surface of the plastic mold, even on the surface of the insert of the plastic mold, which can significantly reduce the friction coefficient of these surfaces, and can achieve a highly glossy processing surface without using a conventional release agent. The design and plastic compounds used make the machine/tool maintenance downtime so long that the production yield is low and the economically unfeasible criticality allows the nano-release coating to extend uninterrupted production time and significantly reduce the machine/tool Maintenance and shutdown period. Make the most efficient and effective plastic mold production and reduce waste. The nano-release coating not only improves the smoothness and precision of the surface of the plastic mold, but also greatly increases the productivity of the plastic mold manufacturing industry!
