Tsutusmi Kougyou Co., Ltd.

We conduct machining of a wide range of resins including FRP, engineering plastics, and thermosetting resin.

We are a resin machining manufacturer that excels at thin-sheet machining, bending, bonding, and other processing for glass fiber reinforced plastic (GFRP) and carbon fiber reinforced plastic (CFRP). The plastic category covers various materials, each of which requires different cautions and methods during processing, but we have established optimal manufacturing methods for each material. Our allowable sizes are a thickness of 0.1 mm for thin machining, and sheet thickness of 5 mm and length of 400 mm for bending. We manufacture products such as display cases with bonding processing. Our polymerization bonding excels in strength. 


Other presentation

[Company strength]
Our company excels at plastic processing such as bending, bonding, and machining for thin, small works using general-purpose machines and machining centers. The category of plastic materials in general includes a wide variety of different properties. Some materials are fragile or easy to bend when heated, while others are hard and difficult to cut, which naturally requires different methods and cautions during production. Our company has been able to establish an optimal manufacturing method for each material after extensive trial and error. These results led us to work with R&D institutions and universities to develop many prototypes. 

[Business description]
Our company provides machining of plastic materials, and we handle all kinds of resins, including FRP, engineering plastics, thermosetting resin, and other general purpose plastics. 

Plastic machining

[Strength of products/technologies]
Machining: Small articles from 2 × 2 to 100 × 200 in size. Our thin sheet machining has earned a particularly good reputation among our customers. We will accurately process thin sheets and thin works by employing a machining method suitable for the material and process. Our minimum allowable thickness for thin machining is 0.1 mm. 
Bending: We can apply bending for relatively large works up to 5 mm in plate thickness and 400 mm in length. Most workpieces make it difficult to be precise, but we maintain quality and accuracy by being cautious. 
Bonding: We can perform bonding processing to make cases such as display cases used in showrooms. These products are manufactured with speed and caution so as not to leave scratches on the surface to protect its appearance. We provide high-strength polymerization bonding.

[Representative's message]
Our management philosophy is to provide products using optimal materials and manufacturing technology to realize satisfying products and a great future for our employees. We do this as a pioneer manufacturer of small-lot resin products. The world as we see it is filled with goods and materials. Our parts might be too small to see, but they surely help to connect people to people, which is something I have come to realize. We will continue to work hard to serve our customers, while asking ourselves what we can do for them. 

[Company structure for market development/overseas expansion]
Our general affairs department has a person in charge of new customers, who functions as the point of contact for major companies. Engineers in the manufacturing department provide technical consulting, and may visit the customer when it is necessary to solve a problem.
