About this part

What it is and why it is made that way

Motor housings are one of the classic high-volume die-casting applications — the fins are cast in, so there is nothing to machine away and nothing to weld on. The bore, the mounting flange and the end faces are machined to the drawing, and the housing is supplied with the bearing seats finished.

  • Cooling fins cast integral — no secondary operation needed
  • Bore, flange and end faces machined to drawing
  • Bearing seats finished in the same setup
  • Aluminium and zinc alloy with material certificate

Materials

  • ADC12 / ADC3 aluminium
  • A380 aluminium
  • ZAMAK-5 zinc alloy
  • A356-T6 aluminium
  • Magnesium alloy

Production processes

  • Cold-chamber die casting
  • Hot-chamber die casting
  • High-pressure die casting
  • CNC trimming and milling
  • Shot blasting and leak testing

Typical applications

  • Electric motor bodies
  • Pneumatic tool housings
  • Actuator bodies
  • Gearmotor frames
