Polyurethane Injection Molding Parts Mould common injection molding silicone
PU injection small knowledge
In the injection molding process, products with many bubbles sometimes appear in the product, which will affect its strength and mechanical properties, and greatly reduce the appearance of the product. Usually due to uneven thickness of the product, or when the mold has protruding ribs, the cooling rate of the material in the mold is different, resulting in uneven shrinkage and easy formation of bubbles, so special attention must be paid to the mold design. In addition, the raw materials are not sufficiently dried and still contain part of the water. When the material is melted, it will decompose into gas and easily enter the mold cavity to form bubbles. Therefore, when bubbles appear in the product, the following factors can be checked and dealt with.

Our injection molding operations have been improved with high quality and sophisticated production.

What is a solid product? Your product can be complicated if you need to: combine

packaging, mass injection equipment, large product sizes and / or thick and thin

cutting areas. We do all this. Injection molds also come in a variety of sizes

machines for determining the size of small and large products.

We prescribe a polyurethane formula that suits your specifications

requirements for each project. Tell us your wishes and we will guide you

through excellent material capabilities.
