To strengthen metals and extend the lifespan of products! We are the doctors of components, tackling various problems with innovative surface treatment technology.
OXISO Co., Ltd. has been honing its surface modification technology for engine parts and molds in Iwata City, Shizuoka Prefecture, where manufacturing technology has been accumulated for many years. Utilizing our accumulated technology and know-how, we understand the challenges faced by customers struggling with issues such as insufficient strength of parts and worsening defect rates on mass production lines. Like a doctor providing precise diagnoses and careful treatment, we identify the problems our customers face, investigate the causes, and offer optimal processing solutions.

Business Activities
◆Metal surface processing of engine parts, molds, device components, cutting tools, robot parts, etc., through precision shot peening and special polishing. *Precision Shot Peening (OX-FSP) By finely selecting shot conditions according to the material, heat treatment, hardness of the product, as well as the usage environment and its countermeasures, we perform processing under optimal conditions aimed at improving fatigue strength and sliding properties. *Special Polishing (OX-POLISH) Through special polishing that applies the surface treatment process cultivated by fine particle shot peening, it is possible to freely adjust surface roughness and also to form plateau structures (special dimples).
