Insert bush WCH

東京鋲兼

The "Insert Bush WCH" is designed for forming processes that roll and process sheet materials, resulting in minimal material loss and significant cost reductions compared to machined products. By applying a unique dimple shape to the outer circumference of the bush, it demonstrates exceptional effectiveness in preventing rotation and disengagement after resin molding. The new type of dimple shape improves the pulling force by 1.7 times compared to conventional designs, allowing for the proposal of products that are more resistant to disengagement. 【Features】 ■ Significant cost reduction by replacing machined products with rolled materials ■ Prevention of rotation and disengagement after molding through a unique dimple shape ■ Capable of processing not only circular but also oval bushes ■ Unique seam adhesion technology that effectively prevents resin leakage
