To form a dish-shaped groove on a plate, it generally required two processes: pressing and machining. Therefore, our company has focused on controlling the shape of the dish-shaped groove and the variation in the surrounding plate thickness. As a result, it has become possible to process using only pressing, which reduces the number of processes. 【Overview】 ■Issue - Forming a dish-shaped groove on a plate generally requires two processes: pressing and machining. ■Solution - Control the shape of the dish-shaped groove and the variation in the surrounding plate thickness. - It has become possible to process using only pressing, which reduces the number of processes. *For more details, please refer to the PDF document or feel free to contact us.

As a weakness of our press processing, due to the nature of processing by clamping with upper and lower molds, we were not good at processing that narrows the opening. In this trial, we overcame that and succeeded in processing the narrowing of the opening. Using a simple prototype for testing, we formed a cylindrical shape in one step. The key point is to control the shape and dimensions after narrowing the opening to the target values. 【Overview】 ■ Issues - As a weakness of press processing, due to the nature of processing by clamping with upper and lower molds, we are not good at processing that narrows the opening. ■ Solution - Control the shape and dimensions after narrowing the opening to the target values. - Formed a cylindrical shape in one step using a simple prototype for testing. *For more details, please refer to the PDF document or feel free to contact us.
