Gravity Casting Services for Custom Aluminum Parts
Gravity casting can be useful when buyers need aluminum cast parts with better tooling economy than pressure die casting, more stable shape than simple prototype routes, and enough allowance for CNC machining.
We review gravity cast parts around alloy choice, mold design, wall thickness, feeding, surface requirement, machining allowance, and inspection points. It is often considered for housings, covers, brackets, and equipment components.
Gravity Cast Parts We Review
Buyer Questions Before RFQ
When is gravity casting a practical option?
Gravity casting can fit aluminum parts that need better structure than some die casting routes, moderate volume, and controlled functional areas after machining.
What should be confirmed before gravity casting?
Confirm alloy, wall thickness, feeding areas, machined faces, mounting holes, sealing surfaces, surface finish, inspection method, and expected production quantity.
Can gravity cast parts include CNC machining?
Yes. CNC machining can be planned for holes, threads, datum surfaces, sealing faces, and assembly areas after the casting route is confirmed.
Before Sending an RFQ
If you are comparing suppliers or preparing a drawing package, start with the RFQ checklist. It explains what information helps us review material, casting route, machining allowance, inspection, and delivery before quotation.
What We Check Before Gravity Casting
Gravity casting works best when the casting and machining plan are reviewed together.
- Aluminum alloy grade, working condition, expected quantity, and tooling expectation.
- Wall thickness, feeding, shrinkage risk, draft, mold design, and surface requirement.
- Machining allowance for holes, threads, sealing faces, bearing areas, and flat mounting surfaces.
- Surface treatment, finishing, burr control, and protection of machined areas.
- Inspection needs such as dimensional report, material report, CMM, leakage, or pressure-related checks if required.
- Sample approval, repeat order stability, packing, and export delivery details.
Gravity Casting Details Buyers Usually Check
These aluminum part references show the types of features buyers normally ask us to review for gravity casting and machining.
Images are existing part references from the site media library. They support RFQ review and are not presented as customer-disclosed project photos.
What to Send for a Gravity Casting RFQ
The drawing should make the final part requirement clear before tooling and sampling are discussed.
- Drawing, model, alloy grade, application, and expected production quantity.
- Machined faces, holes, threads, sealing surfaces, tolerance notes, and roughness requirements.
- Surface treatment, appearance, burr control, and packing requirements.
- Inspection documents, leakage, pressure, CMM, or other test requirements if needed.
