Custom Investment Casting From China Metal Foundry ADC12 A380 Aluminum Die Casting Parts Supplier Casting Services

In the precision manufacturing industry, custom investment casting services from Chinese metal foundries have established new standards for producing high-quality aluminum die casting parts. Our specialized manufacturing capabilities focus on ADC12 and A380 aluminum alloys, delivering components that combine exceptional dimensional accuracy with superior mechanical properties for diverse industrial applications.

Advanced Aluminum Material Specifications
Our investment casting services utilize two principal aluminum alloys, each engineered for specific performance characteristics:

ADC12 Aluminum Alloy (Japanese standard, equivalent to Chinese YL113 and American 383) represents an Al-Si-Cu system with exceptional casting properties . The chemical composition includes silicon content of 9.6-12.0% and copper content of 1.5-3.5%, which provides excellent fluidity during casting with spiral test values reaching 380-420mm . This alloy delivers tensile strength of 230-280 MPa and Brinnell hardness of 80-100 HB, making it ideal for complex, thin-walled components . With a density of 2.68-2.72 g/cm³ (approximately one-third that of steel), ADC12 offers significant weight reduction advantages while maintaining structural integrity .

A380 Aluminum Alloy features a similar Al-Si-Cu system but with distinct compositional differences, including higher copper content (3.0-4.0%) and moderate silicon content (7.5-9.5%) . This composition delivers enhanced mechanical properties with tensile strength exceeding 324 MPa and improved high-temperature performance . The alloy maintains excellent dimensional stability with a solidification shrinkage rate of only 1.2-1.5%, particularly advantageous for components requiring precise tolerances under thermal cycling conditions .

Precision Manufacturing Processes
Our investment casting (lost wax casting) process combines traditional foundry expertise with modern technology to produce aluminum components with exceptional accuracy and surface finish:

Mold Creation and Shell Building
Injection-molded wax patterns created using precision aluminum molds ensure dimensional consistency and accurate reproduction of complex geometries 

Multi-layer ceramic shell building through successive dipping in zircon and fused silica slurries creates robust molds capable of withstanding the high temperatures of molten aluminum 

Controlled drying cycles between coating applications ensure shell integrity and prevent cracking or deformation 

Melting and Casting
Vacuum melting technology ensures superior metallurgical quality with minimal gas porosity, particularly important for ADC12 applications requiring high integrity 

Precision pouring parameters maintain optimal metal temperature and flow characteristics for complete mold filling of intricate designs 

Directional solidification techniques enhance mechanical properties by minimizing shrinkage defects in critical stress areas 

Secondary Processing
CNC machining operations refine critical features, maintaining tolerances within ±0.02mm for precision applications 

Comprehensive surface treatments including polishing, powder coating, anodizing, and shot blasting provide enhanced corrosion resistance and aesthetic appeal 

Advanced quality verification utilizing coordinate measuring machines (CMM) and spectrographic analysis ensures consistent compliance with specifications 

Enhanced Performance Characteristics
Aluminum components manufactured through our investment casting processes deliver exceptional operational benefits:

Excellent Dimensional Accuracy: Maintaining tolerances within ±0.02mm for critical features, reducing secondary machining requirements 

Superior Surface Finish: Achieving surface roughness values as low as Ra 10-1.25 micrometers, ideal for components requiring minimal post-processing
