China Casting Factory for Custom Metal Parts

Relia Casting manufactures custom metal castings in Qingdao, China. Source investment, sand, shell-mold, lost-foam and die-cast components with CNC machining for bores, threads and mating faces. We define material, sample approval and inspection requirements with you before production.

CASTING PRODUCTS

Cast Parts for Industrial Assemblies

See catalogue examples of cast housings, valve components, flanges, brackets and impellers. These references help explain the shapes we manufacture; your material grade, dimensions and finished condition are agreed from your own drawing or sample.

CASTING CAPABILITIES

Match the Casting Process to Your Part

Geometry, material and order quantity guide the casting decision. Start with the process families below, then review wall sections, cores, tooling and the surfaces that need machining with our China factory team.

Investment Casting

Produce detailed steel and alloy components from a lost-wax pattern. Relia reviews water-glass or silica-sol routes against your geometry, specified grade and surface requirements. Define small features and machining stock early so the quotation covers the casting and the finished interfaces.
View Investment Casting

Sand Casting

Source iron or steel housings, bodies and brackets with a mould and core arrangement suited to the drawing. We review internal passages, section changes and machining allowances together. Your enquiry should distinguish the as-cast surfaces from bores, seats and mounting faces that need finishing.

Lost Foam Casting

Review lost-foam casting for component geometry that can benefit from an expendable foam pattern. Relia considers the pattern, material and production quantity together with the required finish. Identify the critical interfaces and inspection scope before choosing this route for a new or repeat project.

Shell Mold Casting

Discuss shell-moulded industrial parts where the moulding route needs to match repeat geometry and the specified material. We review tooling, wall sections, casting allowances and surface requirements before sampling. Agree which features are accepted as cast and which require subsequent machining or inspection.

Die Casting

Plan aluminium or zinc die-cast components around the tool, wall sections and expected order volume. Relia reviews the housing geometry, locating features and any secondary machining with you. State the required surface treatment and acceptance requirements before tooling and sample approval are agreed.

CNC Machining for Castings

Finish the features that make a casting fit into your assembly, including bores, threads, seats and mounting faces. Relia connects the machining datum plan with casting stock and drawing tolerances. Agree the measured dimensions and order-specific inspection records before the finished-part supply scope is confirmed.

Define the Part

Send a drawing or sample reference, intended application and quantity. Mark the fits, sealing faces or load-bearing features that determine whether the finished component works in your assembly.

Agree the Manufacturing Scope

Review material, casting route, tooling and machining stock as one project. Include heat treatment, surface treatment and any order-specified testing in the quotation scope rather than leaving them implicit.

Approve Samples Before Production

Confirm the drawing revision and sample acceptance requirements first. After you approve the samples, Relia arranges batch production to the agreed order and inspection plan.

RELIA CASTING · FOUNDRY, MACHINING AND FINISHING

A China Foundry Connected to Your Finished Part

Relia Casting is a manufacturer in Qingdao, Shandong, China, serving industrial buyers who need custom metal components made to a drawing or an agreed sample. Our casting range includes investment, sand, shell-mold, lost-foam and die casting. The route is selected around the specified material, part geometry and production quantity.

We review the component as part of your assembly. A bore may locate a shaft, a machined face may carry a seal, and a mounting pattern may control alignment. These requirements guide casting stock, machining datums and the dimensions that need inspection. Material grades and acceptance limits are agreed for the order rather than inferred from a catalogue photograph.

Relia performs heat treatment, surface treatment and order-specified nondestructive inspection in our own factory. The applicable methods and records are defined with you. We confirm the drawing and sample acceptance requirements first; after your sample approval, batch production follows the agreed order.

Choose the casting route around the material, geometry and order quantity. Review cores, wall sections, surface finish and machining allowances before tooling and sample approval.

Bring bores, mounting faces, threads and mating features to their specified finished condition. Define the machining datums, tolerances and inspection criteria on the part drawing.

Specify deburring, surface finish, heat treatment where required and protective packaging. Include assembly interfaces and any additional inspection or documentation needed for your order.

QUALITY STARTS WITH ACCEPTANCE CRITERIA

Check the Features Your Assembly Depends On

A casting can look right while a bore, seat or mounting face still needs attention. Relia defines inspection around the material, critical dimensions, surface condition and order-specified test requirements that affect your assembly.

We can provide key dimensional inspection records for the order. Agree the measured features, sampling frequency and acceptance limits before production. Heat-treatment, surface-treatment and nondestructive inspection requirements are included when specified and confirmed for your project.

YOUR CASTING PROJECT

From Your Drawing to Approved Production

A clear casting enquiry connects the part, manufacturing route and acceptance criteria. Share the material, drawing revision and quantity; we review tooling, machining and finishing together before samples and agreed batch production.

BUYER PREPARATION GUIDES

Prepare Your Supply Scope, Records and Machining Details

Use these three guides to decide what Relia will supply, which evidence the order needs and how the finished component will be measured. Then send one clear drawing package for review.

FINISHED COMPONENT SUPPLY

Define the Finished Casting Supply Scope

Start by defining the component your workshop needs to receive. Mark the cast regions, finished bores, sealing faces and mounting references on the same drawing. Relia can review casting and CNC finishing as one project, with the machining work and final acceptance scope agreed before quotation.

QUALITY AND TRACEABILITY

Connect Materials with Acceptance Records

State the specified alloy and delivery condition, then agree the material and dimensional records your project needs. Relia can establish the agreed links between the drawing revision, production steps and inspection records for the order, with the scope defined in advance.

MACHINING REQUIREMENTS

Prepare the Finished Machining Interfaces

Mark the bores, threads, sealing faces and mounting features that make the component work. Define their datums, tolerances and surface requirements on the finished drawing so casting stock, machining access and the agreed inspection scope can be reviewed together.

START WITH THE DRAWING

Send Your Casting Project to Our China Factory

Share your drawing or sample reference, material requirement and expected quantity. Mark the critical fits, sealing faces or other working features, then add finishing, inspection and delivery requirements. Relia will review the manufacturing scope with you before quotation and sampling.
