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:

The basic structure of the injection mould can be divided into seven parts: molding parts, gating system, guiding mechanism, ejector device, lateral parting and core pulling mechanism, cooling and heating system and exhaust system.

For plastic products, it is very important to choose which processing and molding method. Because different processing and molding methods not only have a great impact on the quality of plastic products, but also have great differences in production costs.
