Replacing Machining with Press Processing – [Thick Plate Pressing]

Our company achieves precision riveting and thick plate punching by applying advanced die and press technologies.

This sample demonstrates punching a phosphor bronze plate with a thickness of t6, leaving a 0.2 thickness on all four sides using press technology.
By utilizing this technology, machining processes that would typically require cutting can now be achieved through pressing, allowing us to deliver optimal QCD (Quality, Cost, Delivery) solutions to our customers.

Key Features:
Thick plate punching with a smooth cut surface
Proprietary die technology

If you are facing challenges with fine press processing, please feel free to consult with us.
