What's Injection Molding?

Injection molding is also known as injection moulding. This process uses an injection molding machine to heat and melt thermoplastic materials, inject the molten plastic material into the mold, and cool it to form the required parts or products.

Boyi Custom Injection Molding Solutions

By utilizing Boyi’s customized plastic injection molding solution in China, we offer two process variants – overmolding and insert molding to shape plastic parts. 50 to 1000 ton injection molding machines can be used for on-demand prototyping and production operations.

Plastic Injection Molding

Plastic injection molding is done by injecting molten thermoplastic material into a mold, which is then cooled and hardened in the mold to eventually form the desired part or product.

Overmolding

Overmolding is a method of manufacturing parts using multiple materials. Add injection material layers to existing injection molded parts to form composite parts or construct layered parts.

Injection Mold Tooling

Create reliable injection molds for different stages of product development, helping customers achieve efficient and large-scale production of plastic parts. 

Insert Molding

Insert molding can combine the characteristics of different materials together, not limited to using plastic as the substrate. This method can add plastic coatings or components to prefabricated metal parts.
