Achieving the same quality
as aluminum die casting without molding

Kyoei Design gypsum casting uses vacuum casting for molding to manufacture prototypes and small quantities of aluminum and zinc alloys that are similar to die casting. This method is unique to us as a pioneer in vacuum casting.

Completed castings are measured and checked by a three-dimensional measuring instrument. Quality and dimensional accuracy are guaranteed.
In addition, this gypsum casting method can be applied to simplified molding of plastics.

Die cast gypsum is used in a wide range of fields,
not just industrial applications and home appliances

  • Automotive parts
  • Piping components
  • Audio Equipment
  • Engine peripherals
  • Notebook PC
  • Event decorations
  • Compact camera components for automobiles
  • Home appliances such as LEDs
  • Components for professional-use camcorders
  • Medical devices
  • Theme park attractions, etc.

Low-defect cast products

In the case that gypsum cast is not to standard, the gypsum mold can be modified and the casting method can be changed easily.
