» Deep Drawn Metal Stamping

For over 20 years, we have specialized in draw stamping stepper motor housing or motor frame parts for reputable Japanese electronics manufacturers. Through the years, these stepper motor housing parts became smaller and smaller with the miniaturization of electronics products.

The motor housing diameters decreased from 40mm-30mm(1983), 25mm-20mm(1986), 15mm-10mm(1990), 8mm(2001) to 4mm(2005).

Draw Stamping Die Design and Drawing Capabilities:

• The increasingly smaller stepper motor housing pushed our continuous improvement in die design and manufacturing capability for lower tolerance requirement. Design of transfer die shifted to progressive draw die design.
• Added newer progressive presses total 16 Aida transfer presses, 3 Aida Komatsu servo presses and 48 precision presses (max 200T)
• Weight reduction of the motor housing challenged us to draw thinner stainless steel and aluminum.
• Progressive stamping die for stamping material thickness from 0.2mm-1.6mm
• Draw die for drawing diameter 4mm to 100mm and depth max 80mm
• Design draw die with cam to perform side cut of the stepper motor housing
• Cut within drawn metal portion of the stepper motor housing
