Yoneyama Seisakusyo Co., Ltd.

Performance of waterjet processing technology in medical, automobile and aerospace fields 

Our company is a professional enterprise for waterjet consignment processing. We perform processing such as cutting, drilling and deburring by means of high-speed water jets discharged from a 0.3 mm diameter nozzle. We can respond to non-ferrous metal, resin and ceramic, fragile materials such as glass and silicon, and soft materials such as foamed urethane and foamed silicone, in addition to steel. We conduct business with 600 or more companies mainly related to medical equipment, automobile and aerospace.   


Other presentation

[Company strength]
Our company has more than 25 years’ experience as a professional enterprise for consignment processing of waterjets, approximately 700 customers, and responds to 40-50 customers every month. We receive a number of requests from customers in the respective businesses in the respective industries all over Japan (partly overseas), such as engineering, medical, construction and research institutions. We have three different types of processing machines (made by Shibuya Corp.), and respond by selecting an optimal model according to material properties, size and quantity, and attaining the best performance from each of device having different properties. We established the Waterjet Processing Laboratory in April 2007.

[Strength of products/technologies]
Waterjet is the industry leader of water guns, which discharge ultra-high-pressure water or a mixture of water and abrasive grains at a high speed (Mach 3) and high pressure (3,200 kgf/cm2) from a 0.3 mm diameter nozzle, for processes such as cutting, drilling, groove digging, surface peeling and deburring. Waterjets can respond not only to steels such as titanium, nickel and SUS, non-ferrous metals such as aluminum, copper and brass, resins such as CFRP and polycarbonate, and ceramics such as SiC and alumina, but also to fragile materials such as glass, silicon, ferrite, porous bodies, honeycomb, stone, wood and cloth, and soft materials such as foamed urethane and foamed silicone. 

[Representative's message]
Waterjet processing targets material processing in a wide variety of applications in any industry for its features. Our company can provide the best waterjet processing on the basis of experience and know-how accumulated over many years. Please consider utilizing us regardless of whether you are based domestically or abroad. 

[Company structure for market development/overseas expansion]
Developing a nozzle which is a crucial part for discharging water at the tip of a waterjet is a problem that Chairman Kenji Yoneyama, who is our company’s founder, has researched for many years. We are currently trying to open our patents to nozzle manufacturers, trade companies and the like, release the patents to make it easy for new comers to use them, and reduce product prices of nozzle, thereby expanding companies who employ waterjet processing. In addition, we employ a center & satellite system network for promoting waterjets in other countries and embark on establishing related companies in various regions.
