Mould heat treatment is an important means to improve the hardness performance of steel materials. Generally, it is carried out after the mold is roughed. After the heat treatment is returned, the finishing process is carried out.

During injection molding, there will not be a lot of melt oozing out of the vent hole, because the melt will cool and solidify there and block the channel. Another, you can also use the matching clearance between the ejector rod and the ejection hole, and the matching clearance between the ejector block and the stripper plate and the core to exhaust air.

Plastic mold is the abbreviation of a combined mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding.

The surface quality of plastic products must be strictly required, and there should be no markings, pores, and whitening. Haze, black spots, discoloration, poor gloss and other defects, so in the entire injection molding process, raw materials, equipment.

The gate of the injection mold is the channel that connects the main channel (or runner) and the cavity. The cross-sectional area of the channel can be equal to the main channel (or branch channel), but it is usually reduced. T

The gate, also known as the feed gate, refers to a passage from the runner to the mold cavity, which is the smallest and shortest part of the gating system.

Plastic injection moulds often have some problems. Today, the editor will explain the 9 ‌Common‌ ‌Plastic Injection‌ ‌Molding‌ ‌Mold Defects‌ as follows:
