Yoshikawa Co., Ltd.
We offer cold roll forming to satisfy needs for lightweight parts.
Our company manufactures and sells products processed by cold roll forming. We have been increasing our business volume by supplying products to a wide range of industrial fields from automobiles, buses, and rolling stock to buildings, houses, construction machinery, and showcases. We have several hundred customers in Japan, including Fuji Heavy Industries, Daihatsu Motor, Daihatsu Motor Kyushu, Kirii Construction Materials, and Nikken Build. We possess cold roll forming machines equipped with 28 to 90 mm diameter roll shafts. We can satisfy production needs for steel materials with thickness 0.3 to 6.0 and up to 500 mm wide. There is a trend for lightweight automobiles as an aspect of measures to conserve the environment. This is attracting increasing attention to automotive shock absorbing materials manufactured from ultra-high-strength steel sheets by cold roll forming. We will increase our business volume by satisfying as many needs like this as possible.
[Company strength] Our company possesses cold roll forming machines equipped with 28 to 90 mm diameter roll shafts. We can satisfy production needs for steel materials with thickness 0.3 to 6.0 and up to 500 mm wide. Our pre-press punching functions cover drilling and notching processes with online forming to produce cost advantages. Our resin composite line integrating roll forming and resin forming can also produce decorative products. Our forming machines make it possible for us to supply products to various industries. We provide equipment and quality assurance with step-by-step TPM activities. [Business description] Our company manufactures and sells products processed by cold roll forming. We supply our products to a wide range of industrial fields from automobiles, buses, and rolling stock to buildings, houses, construction machinery, and showcases. We set up an integrated production line for efficient forming (primary processing), secondary processing, tertiary processing, quality assurance, and distribution when we start to manufacture products for each industrial field. We develop cold roll forming technology for new materials and provide product development services as a proposal-based manufacturer of products made by cold roll forming. [Industry] Transportation equipment product and construction and building material development, manufacturing, and sales [Strength of products/technologies] Automobiles are now expected to be more lightweight in order to conserve the environment. We have succeeded in manufacturing lightweight automotive shock absorbing material products from ultra-high-strength steel sheet by cold roll forming to reduce the weight while increasing the strength. Roll forming also reduces the number of parts due to component integration. This also contributes to cost reduction. We conduct efficient production under a production system integrating secondary processing (joining by welding) after forming and quality assurance. [Representative's message] Cold roll forming and resin extrusion molding are our core technologies. We have been devoted to developing, manufacturing, and selling these secondary processes products throughout our corporate history. Our main products are now automotive parts, building materials, STKM, and so on. We have been establishing our own unique position in various industrial fields. We will continue to do our best to be a group of improvement experts. We will work to make more customers aware of us as a small but attractive company with a presence in the market while being involved in many industrial fields. We appreciate your continuing patronage. [Company structure for market development/overseas expansion] Our staff in the sales department are in charge of acquiring new customers and responding to inquiries from major companies. Our sales staff and technical staff work together to solve customer issues and problems if expertise is necessary. We directly visit customers as required for meetings. [Market share/Ranking] We are uncertain about our market share or industrial ranking because we manufacture exclusive products for each manufacturer. [Awards and media coverage] [Awards] TPM Excellence Award (Category A) and TPM Excellence Continuation Award. [Media] Nikkei Venture, "Monozukuri Innovative Business" (February 2001). [Authorization/Certification] Japanese Industrial Standards certification: JIS G3445 and A6517. TPM Excellence Award (Category A) and Continuation Award. ISO 9001 and ISO 14001. [Joint research and development] Tokyo Denki University and Gunma Prefecture Gunma Industrial Technology Center: Joint R&D for cold roll forming technology for ultra-high-strength steel sheets (Strategic Core Technology Advancement Program, since 2015). [Intellectual property] Automotive Window Glass Guide and Structure, Manufacturing Method, and Guiding Device (Japanese Patent No. 4079825), and one other patent.
