Hubs · Axle housings · Rail supportsExplore Industry02 / SHARED OEM CAPABILITY
Move from an application question to a manufacturable part.
Industry context is the starting point. The project is then narrowed to the component, material, process and inspection requirements.
Product discovery
Use industry context to find the cast component category that fits your project.
Manufacturing route
Compare material, casting process, machining and inspection requirements together.
RFQ support
Send a drawing, sample, model, quantity and application for a focused technical review.
03 / MATERIALS & PROCESSES
Keep material and process selection connected to the part.
Material families
- Grey IronHousings, covers and machine structures where machinability, damping and dimensional stability matter.
- Ductile IronHousings, hubs and structural interfaces requiring a practical balance of strength and machinability.
- Alloy / Cast SteelWear, impact and structural castings selected around the confirmed part application.
- Stainless SteelSelected flow-control and corrosion-resistance applications after the service environment is confirmed.
Casting processes
- Green Sand CastingA flexible route for a broad range of medium-to-large castings.→
- Shell MouldingA precision-oriented sand process for selected detailed castings.→
- Investment CastingA route for smaller complex parts and detailed geometry.→
- Lost Foam CastingAn option for complex integrated geometry and reduced parting-line constraints.→
04 / MANUFACTURING CAPABILITY
Built around the casting, not around a generic industry claim.
The manufacturing route is discussed from the drawing, sample, application and confirmed inspection requirements.
