How it works
Alphacasting manufactures precision investment castings to customer designs, with dedicated steel, aluminium and titanium lines. The lost-wax route begins with a wax pattern, builds a ceramic shell around it, removes the wax and fills the resulting cavity with molten metal. Removing the shell exposes the casting for finishing and inspection. Tooling, cores and slides are selected for the geometry and production series; the company offers both manual and automatic wax injection.
Patterns can be assembled around a common sprue, with gates controlling how metal enters each cavity. Alphacasting describes six-axis robotic slurry dipping, stucco application and repeated drying/coating to build the shell. CAD and filling/solidification simulation help develop the part and process before production. Its inspection and process equipment includes coordinate measurement, image analysis, programmable burnout furnaces and aluminium heat treatment.
The supplier lists more than 120 alloys, including carbon and stainless steels, precipitation-hardening grades, aluminium, brass and bronze. It says every heat is spectrographically checked for chemistry, while separately cast tensile specimens assess mechanical properties. Those checks complement the finished component’s drawing and acceptance requirements.
Titanium introduces a different process constraint: reactive molten metal requires controlled shell materials and vacuum melting/pouring. Alphacasting describes thin-wall casting and post-cast chemical milling, using masks and controlled etchant baths to remove selected surface material. Straightening and calibrated checking fixtures address the required shape. Hot isostatic pressing to reduce internal porosity is arranged with specialist partners; most heat treatment is described as in-house, with qualified outside suppliers used where needed.
Published aerospace examples include titanium structures, APU/airframe-door assemblies, complex-cored lubrication/scavenge-pump prototypes, flame-arrestor housings and 17-4PH rings for turbofan components. Rapid prototyping, tooling and downstream assembly, welding, plating or painting can form part of the work package. The useful specification is therefore the alloy, drawing, process route and acceptance plan together, rather than an undifferentiated casting order.

Use & integration
Recorded applications
- Aerospace and defence component manufacture
These describe the reviewed application scope, not confirmed deployments, released requirements or procurement eligibility.
Evidence of maturity
Established commercial foundry with published AS9100:D/ISO 9001:2015 certification through June 2027 and separate dated Nadcap NDT and welding certificates. These cover named management/process scopes; drawing compliance and part approval remain specific to the customer programme.
Commercial availability
Prototype and production orders are offered to customer drawings, without a published minimum-order requirement. Alloy, tooling, finishing, external processing and acceptance scope are agreed for the part. Current lead time and capacity require a quotation.
