China Foundry Casting Service Custom Metalworking Galvanized Iron Sand Casting Parts Aluminium Die Casting Service

As a leading China-based foundry and metalworking specialist, we provide comprehensive casting solutions that combine traditional craftsmanship with modern technology. Our integrated manufacturing capabilities encompass both conventional and advanced casting methods, including specialized galvanized iron sand casting and high-pressure aluminum die casting services, delivering precision components for global industrial applications.

Material Expertise and Performance Characteristics

Our material selection covers a diverse range of engineering alloys to meet various application requirements:

Galvanized Iron Components:
We produce robust iron castings through sand casting processes with optional galvanization treatment. This post-casting electroplating application creates a protective zinc layer that significantly enhances corrosion resistance, making these components ideal for outdoor applications, construction elements, and harsh environment usage. The base iron material provides excellent compressive strength and wear resistance.

Aluminum Alloy Die Castings:
Utilizing premium aluminum alloys such as ADC12, A380, and ALSI12, our die casting services yield components with optimal mechanical properties. These include high strength-to-weight ratios, excellent thermal and electrical conductivity, and natural corrosion resistance. The die casting process ensures dimensional stability and superior surface finish quality.

Advanced Manufacturing Processes

Our production methodology integrates multiple casting technologies:

Sand Casting Technique:
We employ both green sand and resin sand casting methods for iron components. This versatile process allows for the production of large, heavy-section castings with weights ranging from a few kilograms to several hundred kilograms. Our pattern-making expertise ensures accurate replication of complex geometries with minimal draft angles.

High-Pressure Die Casting:
For aluminum components, we utilize advanced cold-chamber die casting machines with precision temperature and injection control systems. This process enables high-volume production of complex, thin-walled components with tight tolerances and excellent surface definition. Our integrated approach includes:

• Computerized mold flow analysis

• Precision tooling design and manufacturing

• Automated casting extraction systems

• In-process quality monitoring

Secondary Processing Capabilities

Our metalworking services extend beyond primary casting operations to include comprehensive secondary processing:

• Precision CNC machining for critical tolerances

• Drilling, tapping, and milling operations

• Surface finishing treatments (painting, powder coating, anodizing)

• Heat treatment for enhanced mechanical properties

• Assembly and welding services

Quality Assurance Systems

We maintain rigorous quality control protocols throughout our manufacturing process, including:

• Spectroscopic material analysis
