三進製作所 List of Products and Services

We manufacture a wide range of products using wire cutting processing, from precision parts such as electrical components, electronic components, and electrical equipment parts to metal parts for construction, fishing gear, miscellaneous goods, and decorations. We accept orders for products ranging from blanks like washers and shims to those that require bending processing. Since mold making is our main business, we can handle a variety of bending processes. Our focus is on delivering thin and small products quickly. 【Features】 - Processing of blank shapes such as washers and shims is overwhelmingly fast. - We have extensive experience with stacked processing even for large quantities. - With a fine hole discharge machining machine, we can set up quickly. - Even if we do not have a rich stock of materials, we have fast procurement routes available (stainless steel, brass, copper, phosphor bronze, nickel silver, aluminum, etc.). - We have a proven track record of processing many materials (titanium, permalloy, kovar, molybdenum, beryllium, silicon steel sheets, gold, gold alloys, silver, platinum, etc.). *For more details, please contact us.

• Processing Contract

For prototypes of washers and spot cases, wire cutting processing is used. For small lots, simple mold production and press processing are available. Quantities range from 1 to a maximum of 100,000 pieces (repeat orders are possible). Available materials include stainless steel (SUS304, SUS301), brass (C2680, C2801), phosphor bronze (C5210, C5191), copper (C1100, C1020), aluminum (C5210, C1050), permalloy, SECC, etc., depending on thickness.

• Other machine elements

18-karat jewelry parts These are parts made through mold production and press processing. We accept the materials and deliver the processed products. Moreover, since they are 18-karat, managing scrap is also an important task.

• Other metal materials

At Sansin Manufacturing Co., Ltd., we accept orders for "prototype metal parts" and "wire cutting processing." Our wire cutting processing, which prioritizes speed, can accommodate urgent requests for short processing lengths on the same day. If you make a reservation in advance, we can also process orders on holidays, and we provide prompt responses to customers via the internet. 【Features】 ■ We also handle new products and development parts ■ Orders accepted for even one prototype ■ Capable of processing pilot holes due to the presence of fine hole processing machines ■ Capable of machining (lathe, milling machine, laser, machining) *For more details, please feel free to contact us.
