OEM Overmold Double Color Plastic Two Shot Molding Two-Color Plastic Injection Mold

What Is Double Color Injection Molding
Double Color injection molding refers to the molding process in which two different materials are injected into the same set of molds,so that the injection molded parts are formed of two materials.Some of the two materials are of different colors,and some are of different hardness and softness,thereby improving the aesthetics and assembly performance of the product.
Advantages of Double Shot Injection Molding
Compared with traditional injection molding,the two-material co-injection molding process has the following advantages:
1.The core material can use low viscosity material to reduce the injection pressure.
2.From the perspective of environmental protectiom,recycled secondary materials can be used for core plastics.
3.According to different usage characteristics,for example,soft material is used for the skin material of thick finished products,hard material is used for the core material,or foamed plastic can be used for the core material to reduce the weight.
4.Lower quality core stock can be utilized to reduce costs.
5.The skin material or core material can use expensive and special surface properties,such as anti-electromagnetic interference,high electrical conductivity and other materials to increase product performance.
6.Appropriate combination of skin material and core material can reduce residual stress of molded products,increase mechanical strength or product surface properties.
7.Porduces a product with a marbled texture.
Development and Application of Double Shot Injection Molding
From the characteristics and applications of multi-color injection molding and dual-material co-injection molding,it can be seen that there is a trend to gradually replace the traditional injection molding process in the future.The innovative injection molding technology not only improves the precision of the injection molding process,provides difficult process technology,but also opens up the scope of the injection molding process.Innovative injection equipment and processes are sufficient to meet the demand for more and more diverse,high-quality,high-value-added products.
Double color injection molding has been widely used in almost all plastic fields such as electronic products,power tools,medical products,home appliances,toys,etc.The production and molding of 2K Color molds,as well as the research and development of double color multi-color injection molding machines and two-color injection molding raw materials have also developed rapidly.
