Among the most often used plastic injection molding techniques in modern manufacturing is insert injection molding. Many sectors, including automobiles, electronics, and medical equipment, use it often.

Insert injection molding is a process in which the insert is pre-fixed in the appropriate position in the plastic injection mold, and then the plastic is injected to form the mold. After the plastic injection mold is opened, the insert is tightly buried in the plastic by the cooled and solidified plastic to obtain a product with inserts such as threads and electrodes.

A modern production technique, insert injection molding has come quite far in the plastics sector since its beginnings in the middle of the twentieth century. Many people choose this sophisticated technique for its capacity to produce complicated parts with improved durability, accuracy, and cost-effectiveness.

Insert injection molding represents a cutting-edge manufacturing paradigm that combines molten thermoplastics with pre-positioned metallic or non-metallic inserts within specialized insert injection molds. This technology fundamentally differentiates itself from conventional injection molding through its requirement for automated or manual insert loading into molds prior to resin injection. By enabling the fusion of dissimilar materials—ranging from engineering plastics to titanium alloys—insert injection molding produces multifunctional composite components with enhanced mechanical strength, thermal stability, and design complexity.

In the production and manufacturing of automotive parts, dashboards are one of the most common automotive parts. Generally speaking, the design of automotive dashboards is also mostly produced by plastic manufacturing. With the development of automobiles in terms of safety and environmental protection, people have higher and higher requirements for the safety and environmental protection of automotive accessories; at the same time, more and more dashboards adopt the appearance design of seamless airbag doors, which puts forward higher and higher requirements for the manufacturing process of dashboards.

Plastic injection molding is an important technology widely used in the field of plastic processing, and its processes are various and have their own characteristics. In the big family of injection molding technology, insert injection molding is a very special one.
