Strictly Control The Manufacturing Accuracy Of Household Electrical Appliances Mould

The size of injection moulding process must not only meet the requirements of use and installation, but also consider the manufacturing of Household appliances mould, equipment performance and raw material flow. Strictly control the factors that affect the precision of injection moulded parts, including the manufacturing precision of household appliances mould, plastic composition and process conditions.

The surface roughness of the injection moulding process depends on the surface roughness of the household appliances mould, so the surface roughness of the household appliances mould is one level lower than that of the product, and it can meet the requirements through grinding and polishing. Injection moulded parts will produce cooling shrinkage in the mould cavity, which makes it difficult to take out injection moulded parts. Therefore, in order to promote demoulding, it is necessary to consider that the inner and outer surfaces parallel to the demoulding direction have sufficient demoulding slope.

Injection moulding is a moulding method of injection mould. The advantages of injection moulding are fast production speed, high efficiency, automatic operation, various colors, size from large to small, easy replacement of product size and complex shape.

Injection moulding is an industry with strong technical and practical ability. In the process of injection moulding, plastic raw materials, carbon powder, nozzles, moulds, injection moulding machines, peripheral equipment, fixtures, sprayers, various auxiliary materials and packaging materials are used. These have brought great achievements to the management of injection workshop. Compared with other industries or departments, there are some difficulties, and the requirements of injection moulding workshop managers at all levels are higher.

Although the structure of household appliances mould may be different due to the type and performance of plastics, the shape and structure of plastic products and the type of injection moulding machine, the basic structure is the same. The household appliances mould is mainly composed of gating system, temperature control system, forming parts and structural parts. The gating system and moulded parts are in direct contact with plastics and change with plastics and products. They are relatively complex and variable parts in household appliances mould, which require high-precision parts.
