fonderie cire perdue france

historical expertise in investment casting

MICROSTEEL, a hard metal machining specialist company (Alacrite, Inconel®, Titanium), relies on its dedicated workshop for all types of machining operations for the finishing of investment or centrifugal cast metal parts.

A ceramic mold is created around the wax part pattern and then removed before casting the metal. Investment casting delivers optimum metal part surface finish with very tight dimensional tolerances.

Advantages of investment casting

  • Tighter dimensional tolerances, reducing or eliminating subsequent machining (js 14 mechanical tolerances)
  • Single part small to medium-volume production runs
  • Multi-alloys
  • Repetitive production runs
  • 3D print-based prototype manufacture

Investment casting manufacturing stages

  • Wax pattern injection
  • Wax pattern cluster assembly
  • Primary layer coating
  • Shell strengthening on an automated line
  • Élimination de la cire par autoclave
  • Couler du métal après cuisson de la carapace
  • Dewaxing
  • Parts cutting and finishing
  • Heat treatment
  • Parts machining
  • X-ray, penetrant and dimensional parts inspection
