Komatsu Spring Industrial Co., Ltd.
Our company has manufactured precision springs as both trial manufacturing and mass production.
Our company has been manufacturing and selling all kinds of precision springs on a made-to-order basis since its establishment in 1941. An advantage of our springs is that they are made with automatic machines from the time of prototype manufacturing. This is how we can supply products with uniform quality even under mass production. Our products are used in many applications, such as clocks, electric devices, telecommunications equipment, OA equipment, car parts, precision instruments, and medical devices. We currently do business with overseas subsidiaries of Japanese companies located in China and Thailand.
- We excel in manufacturing coiling springs, torsion springs and wire forming with materials between 0.02 mm and 1.5 mm in wire diameter.
We accept make-to-order requests and provide integrated services from prototyping to mass production.
We manufacture fine springs with coil shapes invisible to the naked eye. Manufacturing of coiling springs (compression and tension), torsion springs and wire forming with materials between 0.02 mm and 2.0 mm in wire diameter. Types of coil springs include long winding, irregular pitches, irregular outer diameters, straight lines, inclined and conic. Materials that we use involve stainless steel, piano wires, platinum and phosphor bronze. We have transaction records for round and flat wires.

[Company strength] Our company can manufacture products on any scale from trial manufacturing to mass production. Prototypes are made with automatic machines, and this makes it possible to provide manufacturing with uniform quality even in mass production. We elaborate on springs to make them better, by referring to the drawings that we are given. We have 3 factories in Tokyo, Miyagi, and Akita to stabilize supplies. [Business description] Our company was established in 1941, and we have been manufacturing and selling make-to-order precision springs ever since. The shapes include coil springs (extension/compression), torsion springs, and wire forming. We excel at metalworking of materials that are 0.02 mm to 1.5 mm in wire diameter. The materials are stainless steel, piano wire, platinum, phosphor bronze, and so on. Our products are used in a variety of fields, such as electric device components, telecommunications equipment, home electronics appliances, medical devices, vehicles (2-wheeled), and jewelry. [Industry] Metalworking manufacturing [Strength of products/technologies] Metalworking of precision springs with a wire diameter of 0.02 to 1.5 mm is our specialty. Shapes include coil springs (extension/compression), torsion springs, and wire forming. The types of coil springs we manufacture include straight, gradient, conical, irregular pitch, irregular outer diameter, and long winding coils. Materials include stainless wire, piano wire, platinum, phosphor bronze, and so on. Our products are made with various machining tools and NC lathes, and make use of the skills and technologies that we have been accumulating since our establishment. We also manufacture molds and jigs in-house, which allows us to retain high precision and high quality while simultaneously lowering costs. [Representative's message] Our company flourished as a dedicated precision spring factory mainly for camera shutters around the time of its establishment in 1941. Our company has gradually cultivated many other fields since then. These include clocks, electric devices, telecommunications equipment, OA equipment, auto parts, precision instruments, and medical devices. We are also cultivating overseas markets by participating in exhibitions in Japan and overseas. We will respond to any changes in drawings or requests for trial manufacturing until a product is completely suitable for the customer’s requirements. [Company structure for market development/overseas expansion] We provide active support regarding introduction requests through EDI. We consider that overseas markets are the fields we should be targeting from now on. We have a subsidiary in Indonesia, but we intend to manufacture high-tech, high-quality springs in Japan for export. Contract documents will be prepared with support from the Ota City Industrial Promotion Organization. [Awards and media coverage] [Awards] 300 of Japan's Vibrant Monozukuri (Manufacturing) SMEs selection, when it was held for the first time. Excellent Factory accreditation by Ota Ward (1996 and 2011). [Media] Our springs have appeared in: “Gacchiri Monday” (TBS); “Takumi no waza” (Ota Cable TV); “NHK World” (NHK). [Authorization/Certification] ISO 9001, Eco Action 21. [Joint research and development] We intend to start product planning with a designer from 2014 (collaborative development project by Ota Ward).
