Microfusion process

The microcasting process, also known as investment casting, precision casting or lost wax casting, is basically an economical way to manufacture components close to their final shape, with precision and excellent surface finish, in practically all types of alloys.

Benefits

  • Possibility of producing extremely intricate and complex shapes that would be impossible and impractical and/or more costly by other processes;
  • Parts are produced to full size, with little or no further machining;
  • Casting of parts in alloys that are difficult to machine later;
  • Elimination of loss of high value materials, such as inconels, stainless steels and others, during machining operations;
  • Production of parts with good density, uniformity, high strength and no need for rake angles;
  • Thorough surface finish, which is essential for a range of applications;
  • Great possibilities for design variations, with changing shapes, in order to adapt them to use.

Phases

The microfusion process is complex and rich in detail. It is defined in some specific and well-controlled parameters, so that it is possible to produce quality parts. Process parameters cannot be generalized. Each microfusion determines the process parameters depending on the raw material used, type of part and manufacturing environment. The following steps are part of this process:

  1. Tooling Manufacturing;
  2. Injection of the Model in Wax;
  3. Assembling the Wax Bundle;
  4. Ceramic Mold Manufacturing;
  5. Waxing;
  6. Calcination;
  7. Merger and Leakage;
  8. Demoulding;
  9. Finishing;
  10. Heat treatment;
  11. Inspection and Dispatch.
