Our Aerospace Parts Casting Manufacturing Process
Our aerospace investment casting process follows controlled quality procedures aligned with AS9100D requirements. The following breakdown provides additional information.
- Wax moulds: Injecting wax into engineered dies to create wax pattern moulds of the components. Moulds are individually aligned and grouped into a cluster on the sprue.
- Shell building: Investing the sprue into ceramic slurry, followed by stucco coating. We repeat the process up to 10 times to ensure an even thickness and optimal coating.
- Dewaxing: Introducing the wax pattern tree (the sprue) or individual casts into an autoclave for residual moisture and wax removal. This leaves behind a hollow cavity, which is a near-perfect imprint of the product.
- Pouring: The pre-tested molten alloy is gradually poured into the cast via a gate. Vacuum-assisted pouring ensures an even spread, optimal cooling times, and lower risk of hot-corners.
- Knocking: Extracting the cooled castings from the shell using high-pressure water jets. Components are sawed off and the gates ground into stubs.
- Finishing: Removing residual ceramic using shot blasting and chemical baths, and deburring sharp edges.
- Heat treatment: Solution annealing, aging, quenching, tempering, and other processes as required to improve surface strength and hardness.
- Machining: Milling, reaming, and drilling critical contact surfaces, edges, and mating surfaces for excellent tolerances and finish.
- Surface treatment: Electroplating, electropolishing, deburring, sandblasting, or painting to improve corrosion resistance and aesthetics.
- Inspection: Final inspection in line with QMS to check for warp, dents, micro-porosity, and hairline cracks via NDT and spectrometric analysis.
