Nippa Kinzoku Kougyou Co., Ltd.

We satisfy customer needs with various kinds of thermal treatment.

Our company is extending its thermal treatment business. We can handle various kinds of thermal treatment including salt quenching, vacuum quenching, high-frequency quenching, and nitriding, and satisfy various customer needs from high-mix low-volume production to mass production. We have been accumulating knowledge and experience since our foundation in 1973. We make use of this knowledge and experience to consider dimension change rates and strain after thermal treatment based on specific material properties, complicated shapes, and product uses. We manufacture products at reasonable prices based on these considerations. We have many customers among major companies in Japan, such as NSK, Ebara, Minebea, and Amano.0


Other presentation

[Company strength]
Our company provides comprehensive processing services for product manufacturing from a single drawing. We conduct quick, rational thermal treatment by considering strains and curves. We propose optimal thermal treatment for each product, such as straightening to minimize polishing costs and temperature control based on five-year aging predictions. We also support quick turnarounds and can deliver products on the next day at the earliest, and we accept single-article orders.

[Business description]
Our company conducts comprehensive thermal treatment from high-mix low-volume production to mass production. This includes salt quenching, vacuum quenching, high-frequency quenching, and nitriding. We make use of our empirical values and data to estimate dimension change rates and strain after thermal treatment based on specific material properties, complicated shapes, and product uses. Our goal is to reduce customer costs.

Comprehensive thermal treatment

[Strength of products/technologies]
We give top priority to customers. Our business philosophy is to work with harmony and conviction to be a unique company rather than a number-one company. We conceive and create products with the spirit of taking things on right away, without fail, and right until the end. We completely pass down the skills cultivated since our foundation to new generations, and we always provide good products to satisfy customers rather than sacrificing quality to make a profit. Our company has a network linking 500 partner companies and we accept orders that cover from materials procurement to commercialization. We assist customers with cost reduction by directly giving them advice about the technology for considering curves and strains in thermal treatment or preprocessing before machining.

[Representative's message]
Our company is located in the Keihin Industrial Area, and the local SME metalworking companies that used to be our customers have been continuously decreasing due to closure or bankruptcy. We are focusing on acquiring customers in other areas and even overseas so that we can survive. We are making use of our network to extend comprehensive processing services that are not limited to thermal treatment in order to satisfy more customer needs. Our services have just begun to get on the right track. Please make use of our company for your further development if you have any problems with comprehensive processing including thermal treatment.

[Company structure for market development/overseas expansion]
We have precious partnerships based on the trust and achievements we have accumulated in our 30-year history. We specialize in thermal treatment, but we work together with our partners to satisfy all processing needs from pre-processing to post-processing. We support customers from materials purchasing to milling, lathing, tool polishing, plane polishing, cylindrical polishing, mold surface polishing, black profile polishing, buffing, hard chrome plating, straightening, and BT processing. We will further strengthen our system and also establish a reinforced sales system that is capable of faster satisfaction of customer needs.

[Market share/Ranking]
On the basis of our past deliveries we believe that we have a certain market share.
