ミヤマ精工 List of Products and Services

Automotive small motor parts, magnet parts, etc.

The electromagnetic steel sheets used for winding coils were traditionally processed by sintering iron and then machining it. However, this process has been replaced by stacking thin metal sheets and forming them through clinching in a progressive die, which is known as laminated processing. By eliminating machining, costs are reduced by 40%. The laminated structure makes it easier to create magnetic fields, allowing for the production of higher-performance motors. Additionally, it is possible to stack insulators between each metal sheet. We can accommodate requests for shapes and the number of layers, achieving high precision. 【Features of Laminated Processing】 ■ Stacking thin metal sheets and forming them through clinching in a progressive die ■ Reducing costs by 40% by eliminating machining ■ Making it easier to create magnetic fields ■ Possibility of stacking insulators between each metal sheet *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a development case of press forming of machined parts through layered processing. The development focused on aspects such as rivet forming within the press, process shortening through a review of processing methods, and eliminating cutting. Layered processing was carried out using progressive dies. Our company can accommodate requests regarding shape and number of layers, and we can achieve high precision. [Development Objectives] ■ New Method: Layered Processing (Rivet forming within the press) ■ Cost Reduction: Process shortening through a review of processing methods ■ Novelty: Elimination of cutting *For more details, please refer to the related links or feel free to contact us.
