Materials Used for Injection Molding

We provide various plastic materials for injection molding motor stator stacks. It depends on the specific application requirements. Common materials include thermoplastic elastomers (TPE), thermosetting plastics, and epoxy resins.

The selection of the material depends on factors such as temperature resistance, mechanical properties, and compatibility with the motor’s operating environment.

What Is Injection Molding Plastic Insulation

Injection molding for motor stators is a specialized process used to create insulation layers that protect the windings of a motor stator.

This technique involves injecting a thermosetting resin or thermoplastic material into a mold cavity, which is then cured or cooled to form a solid insulation layer.

The injection molding process allows for precise and uniform insulation thickness, ensuring optimal electrical insulation properties. The insulation layer serves to prevent electrical shorts, reduce energy losses, and enhance the overall performance and reliability of the motor stator.

Additionally, injection molding offers the advantage of producing complex shapes and intricate designs, accommodating various motor sizes and configurations.

With its efficiency and versatility, injection molding plays a crucial role in the manufacturing of high-quality motor stators.

Injection molding Plastic Insulation Process

Plastic injection molding for motor stator lamination stacks is a specialized process designed to enhance the electrical insulation and mechanical integrity of the stator in electric motors. This process involves the encapsulation of stator lamination stacks using thermosetting plastic materials, typically epoxy resins or other polymer compounds.

First, the stator lamination stacks are precisely positioned within a specialized mold. Then, thermosetting plastic material, often epoxy resin, is injected into the mold under high pressure. This ensures complete encapsulation of the lamination stacks.

The high temperature and pressure conditions facilitate the curing of the plastic, forming a robust insulation layer. This process not only provides electrical insulation but also enhances the mechanical strength of the stator.

After curing, the mold is opened, and the insulated stator is removed, ready for further assembly or testing.
