Investment Casting
Investment Casting is a casting route used to create metal components from a detailed mould pattern. Dipak Sales lists investment casting within its manufacturing expertise for customers seeking formed metal components based on drawings and application requirements.
The process can be considered when the required geometry contains details or shapes that are not well suited to a straightforward machining or forming route. Final material, casting method and secondary operations remain dependent on the customer's specification.
Investment Casting for Detailed Component Geometry
Investment casting, commonly associated with the lost-wax process, uses a disposable pattern to create a mould around the required component geometry. After the pattern is removed, metal is introduced into the mould and the casting is processed toward the specified finished condition.
Why Investment Casting Is Considered
- Detailed component profiles
- Complex external shapes
- Geometries that may require significant machining if produced from solid stock
- Components where near-net-shape production can reduce later material removal
- Custom parts produced around customer drawings and functional requirements
Design and Process Considerations
Practicality depends on component geometry, required material, dimensional requirements, production quantity and finishing needs. Features difficult to form through conventional machining can be evaluated as part of the casting route.
From Casting to Finished Part
Investment casting does not necessarily represent the final manufacturing stage. Depending on the drawing, cast components may require machining, drilling, milling, tapping, heat treatment, surface finishing, coating or assembly.
Inspection and Material Verification
Dipak Sales lists digital micrometers, vernier calipers, height gauges, depth gauges, dial gauges, bore gauges, coating thickness gauges and other measuring equipment. Third-party facilities are also listed for hardness testing and chemical composition analysis where applicable.
Specification-Driven Manufacturing
Investment casting is one of the manufacturing services listed by Dipak Sales alongside forging, machining, finishing and assembly. The technical team supports complex and mass-production requirements, while the applicable material and process route should be established from the customer's drawing and specification.
