The principle of mold temperature balance in plastic mold cooling system designThe principle of mold temperature balance:1. Due to the complexity of the plastic parts and mold structure, it is difficult to make the temperature of the mold completely consistent, but should be mak...More+
Different treatment of plastic injection mold cooling system principlesDifferent treatment principle:1. The mold temperature is different according to the different plastics, when the plastic requires the molding temperature of the mold to be ≥80°C, the mold must be he...More+
Conformal cooing channel of plastic injection moldThe conformal cooling gate is a new type of mold cooling gate based on 3D printing technolog, because of its processing characteristics, the conformal cooling gate can fit the shape of the product wel...More+
Reasons for making the exhaust system of the injection moldThe gas in the injection mold includes not only the air in the cavity, but also the air in the gate and the decomposition gas generated by the plastic melt, and the steam which caused by plastic in hi...More+
The main reasons for air trapping of plastic injecton moldDuring the injection molding process, the front end of the slight ribs may be air trapped and plastic burnt, and also cause the molded part may become black and carbonized.The mechanism of air trapped...More+
The air trapping position in cavity and exhaust methodThe air trapping in cavity is usually in the following places:1. Thin-wall structure cavity, the end of melt flow;2. The junction of two or more melts;3. The last area where the melt in the cavity rea...More+
Design standard of exhaust slotThe exhaust system should ensure that the gas in the cavity is smoothly discharged, and also prevent the material from entering and exhausting channels from causing flashing of the product or blockage...More+
Parting surface venting of runner systemThere are a large amount of gas in the main and sub channel, these gas are discharged through the pull rod (push rod) during injection processing, a part of gas come out from exhaust slot on parting s...More+
Insert pin of vengting design for molded partsInsert pin of venting:It is difficult to make exhaust slot when end runner is not in parting surface during injection, and there is no matching gap available, but we could make the venting pin at end ...More+
