We are confident about the lost wax casting technique, but still keep moving forward to improve our skills
Lost wax casting process is a method of metal casting that has been known for a long time. We have been developing the basic technology established in the United States, and we have a top share in precision casting in the general industrial field in Japan.
We can handle everything from mold making to the machining process at each base factory.
Also, we have a comprehensive system by cooperating with some partner companies that specialized in surface treatment, heat treatment, and assembly.

Manufacturing Process
01. Wax molding
Create wax patterns by injecting wax into molds.
02. Ceramic coating
Coat about 4 to 6 layers of ceramic liquid and powder on the wax tree.
03. Dewaxing
Remove wax by high-temperature steam pressure.
04. Mold firing
Burn out wax completely, and sinter ceramic mold.
05. Casting
Pour molten metal into the mold.
06. Cutting
Remove the mold and cut products from the tree.
07. Heat Treatment
Realize stable metal structures by heat treatment.
08. Inspection
Inspect the product based on various strict quality standards.
