Achieving cost reduction by converting metal processed products into resin! We were also able to reduce the weight of the parts.
The customer was manufacturing screw and nut parts through metal processing, but it took a long time to produce them due to the cutting process. By using resin, we were able to reduce the cutting and degreasing processes. By repeatedly polishing the surface of the screw-shaped mold, we eliminated the release issues and achieved stable mass production. The use of resin also resulted in significant cost improvements. [Before Proposal] - Screw and nut parts were being manufactured through metal processing. - The following specifications were required for the screw parts: - The fitting of the screw and nut parts must operate smoothly. - They must not break. - It took a long time to produce due to the cutting process. *For more details, please refer to the PDF document or feel free to contact us.

basic information
[After Proposal] - By resinification, we were able to reduce the processes of cutting and degreasing. - There were concerns about the release of the screw shape; if it does not release, the screw shape remains in the mold, making continuous molding impossible. - By repeatedly polishing the surface of the mold with the screw shape, we were able to achieve continuous molding and realize the product. - Resinification also allowed for weight reduction of the parts. *For more details, please refer to the PDF document or feel free to contact us.*
