Capacities For Injection Mold Design And Manufacturing

The mold is designed to encapsulate the stator stacks. Our injection molding process design and fabrication requires advanced technology, equipment, and strict control at every step. The injection mold process typically involves the following steps:


Firstly, our professionals use flat or 3D software to design the mold. Molds usually use light metals, such as aluminum alloys, or high-hardness steels (such as S7) to increase the durability of injection molds.


Secondly, our CNC electrical machine equipment will cut the material precisely according to the CAD drawing and cooperate with the laser cutting technology to ensure the accuracy of the cutting.


Finally, we assemble, adjust, and test the injection mold to ensure that the mold accuracy meets the expected standard.

Injection Plastic Insulation Motor Stator Laminations Process

We excel in the intricate process of plastic injection molding for stator lamination and offer precise control over insulation thickness, resulting in uniform thermal and electrical properties.

The process begins with carefully selecting and preparing plastic resins with optimal electrical and thermal conductivity.

These resins are then melted and injected into specially designed molds. The plastic material can cool and solidify within the mold.

Our skilled technicians closely monitor this phase to guarantee that the resulting stator laminations exhibit the required dimensional accuracy and surface finish.

Additional insulation coatings or varnishes can be applied further to enhance the electrical insulation and durability of the laminations.

Injection Mold Insulation Stator FAQs

Injection molding plastic insulation is a specialized manufacturing process that involves applying a protective insulating layer onto stator components of electric motors through precise injection molding techniques.

During this process, insulation materials, often in the form of thermoplastics or thermosetting plastics, are melted and injected into custom-designed molds that match the intricate geometry of the stator. Once injected, the material cools and solidifies, forming a seamless and uniform insulation layer.

Stator insulation prevents electrical short circuits, enhances heat dissipation, and ensures efficient motor performance. Proper insulation extends the lifespan of the motor and contributes to its reliability.

Injection mold insulation optimizes electrical performance, reducing energy losses due to improved insulation. This can lead to enhanced motor efficiency, resulting in lower operating costs.
