Progressive Stamping Die Design And Manufacturing

The design and manufacturing of progressive stamping die is one of our core projects. Our skilled engineers meticulously craft stamping dies tailored to your specifications.

Though dies take a long time to build and cost higher, the motor rotor and stator laminations produced in this way have a perfect consistency.

In terms of materials, we use high-quality steel to manufacture progressive stamping dies, ensuring their longevity and performance.

Our experienced technicians also excel in die maintenance, implementing routine inspections and repairs to uphold the dies’ efficiency and extend their lifespan.

Additionally, we leverage advanced wire-EDM (Electrical Discharge Machining) and grinder equipment to ensure the utmost precision in the manufacturing process.

Progressive Stamping Process For Motor Cores

We excel in harnessing progressive die stamping production of electric motor cores. Our progressive stamping process is a testament to precision engineering and innovation, enabling us to create intricately detailed and high-performance motor laminations with unparalleled efficiency.

progressive stamping process

The process begins with a continuous silicon steel sheet entering the high-speed press machine; it has a series of dies to perform multiple operations. As the silicon steel sheet advances, the stamping machine works to cut, form, and shape each lamination.

The high-speed press, capable of stamping more than one hundred times per minute, progressive stamping is ideal for small but large-capacity generators and motor laminates. It can produce high quantities in a short period.

Besides, rivet integration can be carried out during the motor lamination stamping process. These rivets are located at the edge of the lamination. Once the stacks are stacked together, the rivets are compressed into the stack area, thus firmly locking each stack.

Segment Motor Core

We have a high-precision segment motor cores manufacturing process. Unlike traditional solid electric motor cores, our motor rotor and stator laminations are divided into individual segments or pieces, each with its unique shape. Then we assembled these segments to form the complete motor core.

Additionally, segment motor lamination stacks offer advantages in terms of weight reduction, heat dissipation, and flexibility in design. The segmented structure allows for better cooling and ventilation and easier assembly and disassembly, making it particularly useful in maintenance or repair applications.

T-Segment motor cores are commonly found in various industrial applications, especially motors requiring frequent maintenance or demanding operational conditions.

Capabilities and Equipment: Examine the manufacturer’s equipment, facilities, and technological capabilities.

Quality Assurance: Inquire about the manufacturer’s quality control processes. Certifications such as ISO 9001 or IATF 16949 are indicators of a commitment to quality.

Samples and References: Request samples of their previous work or existing products to evaluate their quality firsthand.

Visit the Facility: If possible, plan a visit to the manufacturer’s facility. This lets you see their operations, quality control measures, and work environment firsthand.

The main difference between progressive stamping and compound stamping lies in the complexity of the parts produced and the number of operations performed.

Progressive stamping is well-suited for high-volume production of simple to moderately complex parts.

Compound stamping produces parts with intricate shapes, multiple features, and higher complexity in a single operation.

The choice between the two methods depends on the specific design requirements, production volume, and cost considerations.

Rotary notching is generally not as efficient as progressive stamping for high-volume production due to the individual notching of each workpiece.
