Characteristics of Carbon Fiber Reinforced Polymer (CFRP) and Precision Press Processing Methods

Lightweight and high strength. Resistant to rust and excellent heat resistance, it can also be used as a conductive material.

Our company, Yamada Manufacturing Co., Ltd., has built a long-standing trust and track record with our customers in the field of non-metallic resin pressing due to the uniqueness of this sector. We will introduce basic information and know-how regarding CFRP from a perspective that only our company can provide. Please read this before selecting materials or processing. "CFRP" is a material made from synthetic fibers (carbon fibers) that are burned at high temperatures using resin containing carbon as the raw material. It has a performance that is about one-quarter the weight of iron while being approximately ten times stronger. [Our Processing Methods] ■ Reduction of material costs through optimal mold design ■ Increased lifespan with ultra-hard molds ■ Suppression of dust generation by pursuing mold clearance ■ Establishment of a manufacturing line that does not use processing oil ~ If you have any requests regarding the pressing or cutting of CFRP materials, please leave it to us! ~ *For more detailed information, please refer to the PDF 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

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.
