Precision investment casting

Release Date:2021-07-16

Precision investment casting involves the manufacture of high-performance molds for casting complex parts. This process requires high precision and zero defects. When it is difficult or impossible to cast parts by other methods, investment casting is used.

 

During this process, the wax mold used to make the part is covered in the refractory coating. This "sheath" is made of multiple layers of refractory materials. When it is stacked to the required thickness, the mold will be quickly heated to melt the wax and harden the "sheath". This "sheath" is then used as a mold for casting parts.

 

Precision investment casting is challenging because:

 

Need to continuously improve efficiency

Need to continuously reduce costs

Continuous demand for lighter parts
