Kumagai Seiki Co., Ltd.
We are a press parts manufacturer with a goal of becoming a proposal-type enterprise for VA/VE.
We are a parts manufacturer that can conduct integrated processing from metal mold design to pressing and post treatment. We manufacture functional parts that are incorporated in vehicles, industrial equipment, and home electronics products. The mechanism parts for seat belts require the highest level of safety, so they had previously been produced using the fine blanking method. However, we made it possible to produce them by using a general-purpose press machine. We have a production record of 2 to 3 million articles per year. We are further trying to find seeds in new fields by applying our precision shearing technology and cold forging technology.
[Company strength] We can perform extracting and bending, and we can also make press products with three-dimensional shapes by using plastic forming (thinning and thickening). We can handle progressive working with a plate thickness of up to 6 mm. We have strength in integrated handling including heat treatment, barrels, etc. We may be able to make an advantageous proposal for trial development and small lot production by adopting one-shot processing to reduce the initial cost. We will offer proper QCD to customers by using our simple corporate system and flexible support capabilities. [Business description] We can conduct integrated processing from metal mold design to manufacturing and pressing, as well as post treatment, based on product drawings provided by the customer. We manufacture functional parts that are incorporated in vehicles, industrial equipment, home electronics products, and so on. We make VE/VA proposals in order to contribute to enhancing the cost competitiveness of our customer's products and to improve their added value. This is done by making the best use of our metal mold know-how and flexible ideas. [Industry] Die and press processing design and manufacturing [Strength of products/technologies] We can make use of precision shearing to restrain press sagging and fracture surfaces, and finish products with sufficient surface roughness and sliding surfaces without having to apply secondary processing. We have a track record in reducing product costs by 30 to 50%. This is achieved by applying cold forging technology to convert machining to pressing, and by adopting the integration of welding and caulking products. We can process portions requiring high precision on the order of 1/100. We can stably provide high-precision products to customers. [Representative's message] We have recently been displaying our products every year at five exhibitions, large and small, as sales activity to acquire new customers. Our goal is to become a proposal-type enterprise that can make VE/VA proposals to customers. This will be done by applying our precision shearing technology and cold forging technology, which are our company's strengths, and by finding seeds. It goes without saying that we will support customer needs. We hope to further enhance our technical power, and to expand our market in Japan and abroad so that our company is utilized as a production base by our customers. [Company structure for market development/overseas expansion] Two staff members including the president are carrying out sales activities in order to acquire new customers. We assigned a staff member in charge in the engineering department to take charge of technical consultations, who will visit the customer with sales staff if necessary. We have concluded partnerships with two trading companies in the Kanto and Tokai regions in order to avoid weakness in support both in Japan and abroad. We have established a system of cooperation and conduct close information exchange with these companies. [Market share/Ranking] We have a global share exceeding 20% in the market of seat belts for end-users (as of March 2011). [Awards and media coverage] [Awards] [Media] Press Technology Magazine, "Reliable Technology" vol. 214 (FY2008). [Authorization/Certification] Acquired ISO 9001:2008. [Joint research and development] We develop in-mold forwarding type caulking mechanisms. Multiple parts are produced and caulked within the press mold. We develop product processing technology by applying warm working to difficult-to-process carbon steel material. We develop integrated molding articles by applying plastic forming to three-part brazing products (material: SUS304). [Main Clients / Business History (domestic)] NHK Spring, Tokai Rika, Hosei Brake Industry, Taito Kogyo, and so on. [Main Clients / Business History (overseas)] We have a track record of overseas deliveries through our major customers.
