High-precision and complex-shape processing of spring materials (SUS304, SUS631, beryllium, phosphor bronze, etc.)
We offer a comprehensive service, from considering shapes with 3-D diagrams to examining and proposing materials,
plate thickness and various processing methods, followed by testing, evaluation, progressive mold manufacturing and mass production.
We provide 100% support to speed up development for our customers.
When manufacturing round shapes with press stamping there are two ways: curling and drawing.
Either method is available at our company.
We'll propose the optimal method keeping in mind the purpose for using the product, the required strength, the lead time allowed, etc.
Our company specializes in manufacturing components using micro-slit processing, micro-curling processing, and complex bending processing techniques. We have extensive experience in producing contacts and leaf springs for devices such as mobile phones, computers, and connectors.
