Sanpou Kasei Co., Ltd.

We are actively introducing new molding methods and have developed high-strength CFRPs.

We manufacture a wide variety of plastic parts such as building piping parts, automotive parts, and medical parts. We have introduced new molding methods such as fine injection foam molding “MuCell” and “DSI molding” which can mold shapes with complicated internal hollows, to meet customer demands. We can supply super-engineering plastics such as ultra-high molecular weight polyethylene (UHMW-PE). We succeeded in developing high-strength materials as thermoplastic prepregs, a kind of carbon fiber reinforced plastic (CFRP) produced by impregnating carbon fibers with thermoplastic resin. We aim to expand sales by leveraging these technologies.


Other presentation

[Company strength]
We have worked with customers to create products considered difficult to develop while using our high-mix low-volume production, experience gained over the years, and a wealth of knowledge and skills. We have successfully developed various new products using many ideas. We acquired ISO 9001, which is evidence of our excellent quality maintenance and management system.

[Business description]
We supply a wide range of resin parts, from general-purpose resins to super-engineering plastics, and have expanded our business through plastic processing. We have a proven track record of developing various products, including construction piping parts, special plastic screws, automotive parts, recorder parts, regular coffee mills and parts for the extraction mechanism, pressure-tight cases, multifunction syrup nozzles, leisure parts, register parts, medical parts, and pump parts. We have built solid relationships with blue-chip companies such as Bridgestone Corporation, Yokogawa Electric Corporation, Panasonic Corporation, Fuji Electric Co., Ltd., and Iwaki Co., Ltd.

Plastic molding and processing

[Strength of products/technologies]
Sanpo Kasei Co. is committed to new technologies. We introduced gas assist injection (AGI) in 1995, die slide injection (DSI) in 1997, and MuCell molding in 2003, thus successfully producing resins for difficult-to-machine products which cannot normally be molded. We have developed unprecedented high-strength materials as continuous fiber thermoplastic prepregs, as well as portions of insert parts in an inter-industry new business development plan since 2014.

[Representative's message]
We have been actively introducing new technologies such as AGI, DSI, MuCell molding, etc. to meet customer demands. We can handle thick wall molding, injection molding of ultra-high molecular weight polyethylene (UHMW-PE), continuous fiber-reinforced thermoplastics insert molding, and other shapes which have been conventionally considered difficult to mold. We will continue to make best use of conventional technologies, know-how, etc. in the future as in the past in order to meet customer demands. We will also focus on expanding sales to strengthen our business base.

[Company structure for market development/overseas expansion]
The person in charge of answering inquiries from domestic major companies is also responsible for new customers, while everyone including the CEO works quickly to respond to customers. Experienced engineers handle technical and manufacturing consultations such as design and materials, and directly visit customers for meetings as needed. We will build a system that enables employees to actively participate in various events.

[Market share/Ranking]
Although our market share is unknown, we have delivered products to many blue-chip companies.

[Awards and media coverage]
We have received awards from companies such as Bridgestone Corporation, the former Sanyo Electric Co., Ltd., and Materials Life Society, Japan.
