China Casting Factory for Custom OEM Components

Qingdao Reliacasting Co., Ltd. handles drawing-based casting and machining projects under the Relia brand. Order-agreed heat treatment, surface treatment and non-destructive testing are carried out in Relia’s own factory. Keeping these operations in the component plan helps us resolve a practical issue early: the material condition, machined geometry and final surface must describe the same delivered part.

For an agreed order, Relia can provide applicable material information and establish linked records for the part or batch. We define the report items and production stages covered with you, so the evidence follows your purchasing requirement rather than an assumed universal document package.

Investment casting uses expendable patterns and a ceramic mold for detailed forms. Sand casting uses a mold and, where needed, cores for housings and internal spaces. Shell molding uses resin-coated sand against heated tooling, while lost foam consumes a foam pattern during pouring. We compare those routes with your alloy, geometry and repeat demand. Forging remains a separate route for a component whose design calls for a deformed-metal blank.

An equipment builder may want a complete cast-and-machined part. A machining workshop may prefer a casting blank with mapped stock. A maintenance team may begin with a worn sample and installation details, while an importer needs multiple drawing numbers kept separate through packing. We make that boundary visible in the quotation so tooling, finishing, records and recurring supply can be compared on a consistent basis.
