Maruyoshi Kougyou Co., Ltd.
We manufacture machine parts by cold forging and machining.
Our company started to tackle cold forging early on, and we have accumulated know-how in this field, which features high production speed and minimal post-processing such as cutting. We have realized cost reduction and short turnarounds and we now receive new inquiries and a broad range of orders from companies. This includes firms listed on the First Section of the stock market. Our greatest feature is ultra-deep hole drilling. We can drill holes as deep as 13.9 in terms of the hole ratio of hole depth to hole diameter, while other companies can drill to a depth of 3.5. We have an integrated automotive part production system covering from material cold forging to cutting, thermal treatment, surface treatment, and assembly. We also have experience in manufacturing bearing inner rings for medical equipment, engine pins for agricultural machines and implements, and roller units for textile machines.
[Company strength] Our company has concentrated on total productive maintenance (TPM) activities involving all our staff since 1995 in parallel with our challenges involving new activities. We review conventional manufacturing processes and make continuous improvement efforts to raise productivity and quality and to lower manufacturing costs. Each individual improvement in TPM activities seems very inconspicuous, but continuous improvement activities result in great cost reduction. We are also concentrating on strengthening our management system based on TPM activities. We are now tackling production efficiency improvement in each manufacturing line unit. [Business description] Our company used to purchase thermally treated or processed materials and provide machined and assembled products, but manufacturers began to do preprocessing themselves due to the trend of cost reduction. We felt it was urgent for our survival to manufacture products with unique advantages and high added value, and we set our sights on cold forging. Cold forging is difficult compared with pressing and die-casting, and it cannot be quickly mastered. We started to tackle cold forging early on, and we have accumulated reliable technologies and know-how. Our technologies are capable of achieving cost reduction and short turnarounds, and they have been attracting attention. We now receive new inquiries even from companies listed on the First Section of the stock exchange as well as a broad range of orders from our existing customer companies. [Industry] Machined part manufacturing [Strength of products/technologies] We manufacture cold-forged products by compacting metal materials (nonferrous metal, stainless steel, alloy steel, carbon steel, and so on) with room-temperature molds. Cold forging features production speeds as fast as one piece per second and shapes and dimensions close to those of assemblies. Cutting and other processes can be minimized to reduce the machining time, so cold forging enables fast mass production. Cold forging can suppress costs compared with machining because it is almost free of material losses. Our greatest feature is ultra-deep hole drilling. We can achieve 13.9 in terms of the hole ratio of hole depth to hole diameter while other companies have technical levels of achieving 3.5. We can also handle hard SUSJ2, which is difficult to machine. [Representative's message] Our company was able to celebrate its 50th anniversary on November 2, 2012. We now have a corporate history dating back over 50 years, so we will continue to pursue three major elements to be a truly attractive company. We will be a company that always pursues stability and further potential, that seeks happiness for our staff, and that pursues benefits and satisfaction for society. We look forward to meeting new customers through J-GoodTech. [Company structure for market development/overseas expansion] We established Maruyoshi Kogyo (Dalian) Co., Ltd. in Dalian, China in 2009. We installed cold forging equipment and machining and assembly lines to satisfy requests from a broad range of customers. Please contact our sales department if you have any inquiries. [Awards and media coverage] [Awards] [Media] [Authorization/Certification] ISO 9001 [Joint research and development] Daido University: Warm forming of stainless-steel solenoid valves (2% Si) and evaluation of film lubricant. [Main Clients / Business History (domestic)] JTEKT Corporation, Nachi-Fujikoshi Corp., and so on. [Main Clients / Business History (overseas)] Indirect deliveries to overseas customers.
