[Technology Introduction] Ultra-Precision Punching - PPL

By ensuring thickness intersection solely through pressing and minimizing punch droop, we achieve no need for double-sided polishing!

Toyoshima Manufacturing Co., Ltd. is engaged in the development of a unique pressing method that combines single-process cold forging and parts forming, establishing a flexible integrated production system that achieves high quality and low cost. In "Ultra-Precision Punching," we accommodate thick plates exceeding 10 mm, parts with varying thicknesses, those with a punch width smaller than the plate thickness, and irregular shapes like gears and keys. We have achieved high-precision 100% shear punching that was impossible with general presses. 【Features】 ■ 100% shear punching of plates with thicknesses of 10 mm and 13 mm simultaneously ■ Realization of no double-sided polishing ■ Ensuring a surface roughness of Ra3.2 with forged finishing ■ Forming from cut steel bars *For more details, please refer to the PDF document or feel free to contact us.
