Why This Route Exists
Precision casting is chosen when a part has to come out of the mould close to final shape, with dimensions and surface good enough to skip most machining. Eurona covers the silica sol lost wax process and quick-drying investment casting in one scope.
The route suits parts between 0.01 kg and 300 kg, and mid to small complex structures from 1 kg to 80 kg, where dimensions, surface and mechanical properties all have to be balanced at once.

Process And Quality Capability
The precision casting scope now includes the former investment casting business, so one route covers both silica sol lost wax and quick-drying investment casting.
Parts where appearance, assembly and dimensional consistency are demanding.
Carbon steel, low alloy steel, stainless steel and quenched and tempered grades.
What Usually Goes Wrong Without This Route
- Machining a complex shape from bar stock wastes material and lead time on features that could be cast in.
- Sand cast parts need too much cleaning and still fail the assembly gauge.
- Suppliers hold tolerance on the first sample but drift on the second and third batch.

Precision Casting — Frequently Asked Questions
What weight range does precision casting cover?
0.01 kg - 300 kg
Which materials are available for precision casting?
1.4304 / 1.4308 / ASTM 8620 / 2Cr13 / 20Mn5 / 42CrMo4 / S355
Can machining and surface treatment be included?
Yes. CNC machining, dimensional control, surface treatment and necessary pre-assembly are coordinated in the same supply chain, so parts can be delivered finished to the drawing.
What is needed to get a quotation?
Drawings, material, quantity, quality standard and target delivery date. Those five items allow a process route and a suitable production base to be proposed.
