■Company Outline

Kato Seisakusho Co., Ltd. possesses deep drawing and multiple side piercing techniques to form heat- and corrosion-resistant alloy products with equal thickness. We are the company to perform these processes only with one pressing machine on a mass-production basis, and the techniques have won various prizes. Our exhaust gas sensor cover for motor vehicles has a 60 percent share of the global market.

■Main Products

Our products include automotive components, such as for exhaust oxygen sensors, air bags, common rails, injectors, engine valves, and insert molded switches. They also include components for gas appliances, kerosene heaters, housing-related products, and other devices. To produce those products, we have an integrated system for mold design and fabrication, precision metal stamping, plastic insert molding, and assembling. In addition, we have five manufacturing bases in Japan and abroad to optimally provide products to the locations designated by customers.

■Core Competence

Based on our deep drawing techniques, we have an integrated pressing work system to form various heat-resistant stainless steel plates into components for vehicle exhaust oxygen sensors and to pierce on their side. In particular, one of these components has more than a 60 percent share of the global market. We are committed to helping protect the global environment through the production of exhaust sensor components, which are one of the world’s leading innovative products.
Our deep drawing press processing, which features our expertise to minimize differences in product thickness and pierce on the side of product periphery during mass-production, embodies artistic craftsmanship that cannot be duplicated merely by a machine. This advantage makes our products extremely competitive in the market compared to those of other companies.
