What are the influencing factors of the appearance of injection mould products?

For injection parts to ensure the appearance quality is a very important aspect, to achieve good appearance quality is a problem that each injection molding manufacturer should pay attention to. Factors influencing the appearance of injection moulds include geometry of injection moulds, selection of resin materials for injection moulds and structural design of injection moulds.

1. Geometry of injection mold parts

Melting, flow, cavity filling and resin curing all have basic physical laws; The geometry of the injection mold part of that part determines how these physical laws will behave in the appearance of the injection molded part. The shape and size of the injection parts need to be strictly calculated when the mechanical parameters, combined with the structural strength of the plastic raw material itself to design, unreasonable structure design will only let the appearance of the injection parts of the quality is greatly discounted.

2. Selection of resin raw materials for injection molding

The resin you choose will have a huge impact on the appearance of the injection molded product. The obvious effect is the color, but beyond the color there are many aspects affected by the choice of material. Some resin materials for colorant compatibility is relatively poor, the subsequent coloring effect is not guaranteed so naturally can not get satisfactory appearance quality.

3. Structural design of injection mold

The structural design of injection mold also has a great impact on the appearance quality of injection parts. Some molds are made at a low level, the inner wall is not smooth enough or the size design is not good enough, and the appearance quality of the injection parts produced is certainly not satisfactory. The surface of the injection parts made from the rough mold surface will also be relatively rough.

Plastic products often need injection mold for mass production, injection molding quality also marks the design of injection mold to meet the requirements. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before injection molding with customers from the production needs of finished products, so as to make the injection mold delivery time short, long life, rapid mass production and finished product quality excellent!
