lost wax investment casting foundry uses the yellow
wax and water glass as the materials. The lost wax
process makes the castings to keep the surface and
inside inspection, and relative low cost. We are
willing to challenge the small batch of demand with
special materials and making prototypes.
wax investment casting is a kind of precision
casting process, which can reach dimensional
tolerance ISO 8062 CT 5-7. The materials include
carbon steel, alloy steel, and stainless steel.
of metal foundries in China mainly used this lost
wax casting line to produce steel castings. Only
some could produce iron castings by this process.
are two types of investment casting workshops, one
type is using the water glass as the main material,
another is using the silica sol. The silica sol
investment castings have better dimensions and
surface quality, but just too expensive than water
glass. It is normally two times of the cost of water
wax investment casting workshops and foundries are
reducing in China. It is mainly because of the high
material costs, reducing exchange rate, and the
energy saving and emission reduction by government.
However, this process is still the most suitable
casting production method for small steel castings.

this casting process:
