Press processing of magnetic materials

Press processing of magnetic materials

Utilized to realize various functions by leveraging the properties of ferromagnetic materials.

At Kato Manufacturing Co., Ltd., we process products using soft magnetic materials (Permalloy) through press processing, ensuring a combination of high-precision punching and high-precision bending. We achieve a general punching tolerance of plus or minus 0.05 mm and a bending angle tolerance of zero plus 0.1 mm, establishing a mass production system. Particularly, since Permalloy is a very expensive material, the occurrence of defective products is not permitted. Therefore, high reliability in molds and long-lasting processing are required. **Characteristics of Permalloy** - Low coercivity and high permeability - Used in magnetic cores for coils and transformers, magnetic yokes, magnetic shields, etc. - Has the ability to easily respond to slight changes in magnetic fields For more details, please contact us or download the catalog.

Copper material pressing process

Copper material pressing process

It is commonly used as materials for wiring components, circuits, and cables in electrical appliances.

At Kato Manufacturing Co., Ltd., we use tough pitch copper with reflow tin plating to press parts called lead frames, which support and fix semiconductor elements (semiconductor chips) used in semiconductor packages such as ICs and LSIs, and connect them to external wiring. When pressing the plated copper sheets, due to the material characteristics of having a hard surface and a soft interior, the mold punch is prone to seizing, requiring careful selection of mold materials and lubrication. Additionally, because there are terminal components that resemble centipede legs, as well as numerous burr processing and pilot hole processing of similar thickness to the sheet, special measures are necessary to prevent scrap and punch breakage, and high-level technology is required to meet the quality demands of all holes and terminal parts. 【Characteristics of Tough Pitch Copper】 ○ Copper alloy number: C1100 ○ Composition: Cu 99.90 or higher ○ Tensile strength: 245–315 N/mm² ○ Elongation: 15.0% ○ Hardness: 75.0–120.0 HV For more details, please contact us or download the catalog.
