Nishino Manufacturing Co., Ltd. "Machining, Dimensional Restoration, and Performance Durability Improvement Reprocessing Technology"
A technology for special heat treatment welding of cast parts used in construction machinery engine components.
Traditionally, welding repair of cast iron parts (FC imono) has been considered a temporary fix, and welding repairs were deemed impossible. However, since 2002, Nishino Seisakusho Co., Ltd. has adopted a granular nickel alloy welding material and a unique heat treatment method, resulting in excellent weldability without the occurrence of secondary cracking, which could not be resolved with cast iron (FC imono) welding, and without making the material hard. Analysis by the Muroran Institute of Technology's Regional Collaborative Research and Development (CRD) Center has confirmed that the performance and strength exhibit sufficient welding strength. 【Features】 ○ Repair parts, even if they are old and have deteriorated due to oil, chemicals, etc., can be easily processed. ○ The welded area has a higher tensile strength than the original cast iron material. ○ It has ductility, impact resistance, corrosion resistance, and is easy to machine. ○ It is low-cost and machining is also possible. ○ Registered as a utility model.

Company information
Nishino Manufacturing Co., Ltd. was established in 1971 (Showa 46) in Muroran, Hokkaido, as a company specializing in the production of machine parts. Initially, our main business was the manufacturing and repair of general industrial machinery, but in response to increasing demand, we introduced large processing machines and gradually implemented surface modification technologies such as hard chrome plating, thermal spraying, and special welding, which are also applied in regeneration processing techniques. Currently, we are capable of integrated production from machining to surface modification treatment within our own factory, allowing us to respond with low prices and short delivery times. Recently, the reuse of machine parts has become one of the pillars of our business. This aims to extend the lifespan of entire facilities through parts repair and regeneration processing utilizing the surface treatment technologies owned by Nishino Manufacturing. By expanding reuse, we have received great acclaim for our ability to simultaneously reduce costs associated with equipment repairs and waste. We aim to provide products that can respond to the diversification of needs while proposing total benefits to our customers, such as economic efficiency and reduced environmental impact, through the various processing technologies we possess.
