Investment-Cast Bronze Bushings & Fittings
Investment-cast bronze bushings and fittings, with close tolerances and a fine surface finish from the lost-wax process.
Investment-cast mounting brackets and standoffs, with fixings machined to position so they land on the tooling holes first time.
| Part weight | 5 g – 15 kg |
|---|---|
| Dimensional | ±0.05 mm general (to print); ±0.02 mm on critical features |
| Surface | Shot blasted, tumbled, passivated or electropolished |

The reason to replace a stamped bracket with an investment casting is usually tolerance or shape. A casting holds a complex form and holds its position, and the fixing holes are machined after casting so the part drops onto the existing tooling without adjustment.
The ranges below are what this shop typically holds. Anything tighter than the baseline is possible — send the drawing and we will confirm it against your specific tolerances rather than quote from a table.
| Part weight | 5 g – 15 kg |
|---|---|
| Dimensional | ±0.05 mm general (to print); ±0.02 mm on critical features |
| Surface | Shot blasted, tumbled, passivated or electropolished |
| Porosity | ≤1% gas porosity on critical surfaces, to agreed specification |
| Inspection | X-ray and dye penetrant testing available on request |
| Hole position | ±0.05 mm from the datum |
| Mounting face flatness | ≤0.10 mm |
| Part weight | 10 g – 4 kg |
If this is not quite your part, these are made on the same equipment with the same inspection.
