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.

Generally, aluminum die-casting chips were made from SKD61 hot work tool steel, but recently there are also chips made from cost-effective chrome-molybdenum steel (SCM). After wear from use, during the dimensional restoration and overlay welding regeneration process, at Nishino Manufacturing, SKD61 material is used for overlay welding on the outer diameter of such chips, and unique heat treatment and nitriding processes are applied for dimensional restoration. The performance of these chips is almost on par with those made from conventional SKD61 hot work tool steel. 【From Used Regenerated Products to New Manufacturing】 ○ Thermal spray chips for aluminum die-casting ○ Die-casting plunger chips ○ Die-casting plunger sleeves For more details, please contact us or download the catalog.
