Custom Casting Solutions

Custom castings are widely used in industrial equipment, automotive systems, infrastructure projects, and heavy machinery. Each project requires appropriate material selection, casting processes, and quality control standards to ensure reliable performance.

Tiegu supports international buyers by coordinating qualified foundries across China. Through our integrated supply network, we help customers source customized casting solutions according to their drawings, technical requirements, and production volumes.

Our approach focuses on matching suitable manufacturing capabilities while maintaining stable quality control and export coordination.

Our Custom Casting Capabilities

We support a wide range of custom casting requirements, from small precision components to medium and large structural castings.

Each project is evaluated based on material requirements, product structure, dimensional tolerances, and expected production volume.

Supported Casting Processes

Different casting processes are selected depending on part geometry, dimensional accuracy requirements, and batch size.

Common casting processes include:

Sand Casting
Widely used for medium and large structural components. It offers flexibility for customized shapes and cost-effective production.

Investment Casting
Suitable for precision components requiring better surface finish and tighter dimensional tolerances.

Lost Foam Casting
Ideal for complex structures with integrated design and fewer parting lines.

CNC Machining and Finishing
Machining operations such as milling, drilling, and surface finishing can be coordinated to meet assembly requirements.

Materials for Custom Castings

Material selection plays a critical role in the performance and durability of casting components.

Common materials used in casting projects include:

Ductile Iron
Known for its excellent strength and ductility. Commonly used in structural automotive and machinery components.

Gray Iron
Provides good vibration damping and machinability. Widely used in engine components and industrial equipment.

Carbon Steel
Offers higher tensile strength for load-bearing applications.

Alloy Steel
Enhanced with alloying elements to improve wear resistance and durability in demanding environments.

Material grades are selected according to project specifications and international standards.

Casting Project Workflow

Custom casting projects typically follow a structured workflow to ensure technical clarity and production stability.

RFQ and Drawing Review
Customers provide drawings, material specifications, and project requirements for technical evaluation.

Supplier Matching
Qualified foundries are selected based on casting process capability, material expertise, and production capacity.

Quotation and Technical Confirmation
Pricing, material standards, machining requirements, and inspection specifications are confirmed before production.

Sample or Trial Production
Prototype or sample production may be arranged when necessary.

Mass Production
Once approved, the project enters regular production with coordinated quality control.

Inspection and Delivery
Finished products undergo inspection before packaging, shipment arrangement, and export documentation preparation.

Quality Control Coordination

Quality control is a critical aspect of casting projects, especially for export orders.

Typical inspection activities include:

Material certification verification
Chemical composition analysis
Mechanical property testing
Dimensional inspection
Non-destructive testing (NDT)
Third-party inspection when required

These inspection procedures help ensure consistency and compliance with technical specifications.
