Rust causes of injection mould and solutions

Rust causes of injection mould and solutions:

As we all know, injection molds are mainly made of tool steel. During work, they will encounter corrosive gases, water and other substances that cause rust. Plastic parts made of rusty molds often have quality problems, so we must find out the causes of rust in the molds and solve them.

Reason 1: When the mold raw materials are overheated, they will produce volatile gases, which are mostly corrosive. When the mold is not working, they will diffuse around the mold, causing rust.

Solution: When the mold stops working, the operator should use a soft cloth to clean the mold. If the mold is not used for a long time, the mold cavity should also be sprayed with anti rust agent.

Reason 2: In the cooling process of the mold, the water in the surrounding air will form water drops on the mold surface. If it is not wiped in time, it is easy to rust.

Solution: Shut down the cooling water system and dry the mold in time after the mold stops processing.

Injection mold is an important process equipment for producing various industrial products. With the rapid development of the plastic industry and the promotion and application of plastic products in aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the demand for injection mold in various industries has greatly increased.

Eight common injection mold structure classification One. Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated, so as to take out the plastic parts, which is called single parting surface mold, also called double-plate mold. It is the simplest and most basic form of injection mold, which can be designed as single-cavity injection mold or multi-cavity injection mold according to the need, and is the

The difference between injection moulds and plastic moulds Many people can’t tell the difference between injection molds and plastic molds, and many people even think that they are the same kind of molds, just called different. Although injection molds and plastic molds are both molds, but there is a difference between them. Want to figure out the difference between the two, first and Xiaobian together to understand what is injection mold, what is plastic mold.
