Precision Casting Parts
Lost-wax castings in stainless, alloy and bronze, for shapes and tolerances sand casting cannot hold.
What this process is
Precision Casting Parts, in plain terms
Investment casting builds a ceramic shell around a wax model and melts the wax out, leaving a mould fine enough to reproduce small features and thin walls with a smooth surface. It costs more per part than sand casting and is the right answer for small, complex, high-accuracy parts in corrosion-resistant alloys. The critical features are machined after casting.
When this is the right answer
- Small complex parts in stainless, alloy steel and bronze
- Thin walls and fine detail that sand casting cannot hold
- Corrosive, hygienic or high-temperature applications
The trade-off. Investment casting is more expensive per part than sand casting and usually more than die casting. It earns that cost where a sand casting would distort the shape or where the alloy and finish rule out other processes.

What to send for a quote
- A drawing or 3D model, and the alloy grade required
- Rough size and weight of the part
- Surface finish and any certification required
- Annual volume, which sets the shell and pour economics
If you only have some of these, send what you have. We will ask for the rest.
