What Our Aluminum Die Casting Service Includes
We provide a complete aluminum die casting solution that covers each step needed to bring your parts from drawing to mass production.
Mold Design and Tooling
We review your drawings, part function, and production volume to design aluminum die casting molds that balance performance, tooling life, and cost. Our tooling team focuses on proper gating, venting, and cooling design to support stable casting quality and efficient cycle times.
Aluminum Alloy Die Casting
We offer custom aluminum die casting for complex shapes that require good strength-to-weight ratio, tight dimensional repeatability, and high-volume productivity. The process supports thin walls, intricate geometries, and integrated features that reduce secondary assembly operations.
Precision CNC Machining After Casting
For features that need tighter tolerances, we provide CNC machining after die casting to finish critical surfaces, holes, threads, and interfaces. This combination allows us to deliver parts that meet your functional requirements while keeping the casting process efficient.
Surface Preparation and Finishing
Depending on your design and application requirements, we offer trimming, deburring, grinding, and polishing, followed by powder coating, painting, or other surface treatments to achieve the desired appearance and corrosion resistance.
Assembly and Customized Packaging
We can assemble multi-component sets, add inserts or hardware, and provide customized packaging and labeling based on your logistics needs. This helps you simplify downstream handling and reduce on-site assembly workload.
Quality Inspection and Documentation
Our inspection process includes dimensional checks, material verification, and visual inspection aligned with your drawing and quality requirements. When needed, we can support documentation such as inspection reports, capability studies, and sample approvals.
How Our Aluminum Die Casting Process Works
A clear and controlled process is essential for reliable aluminum die cast parts. Below is how we typically handle an OEM project from initial inquiry to stable production.
Drawing Review and DFM Analysis
We start by reviewing your 2D/3D drawings, functional requirements, and expected quantities. Based on this information, we provide basic DFM feedback for aluminum die casting, such as wall thickness, draft angles, fillets, and potential undercuts that may affect tooling and production.
Mold Design and Tooling Fabrication
Once the design is confirmed, we design and manufacture the aluminum die casting mold. Proper mold design is essential for stable filling, solidification, and ejection, which directly impact part quality, cycle time, and tooling life.
Trial Runs and Sample Approval
We conduct trial casting runs to optimize process parameters such as injection speed, pressure, and temperature. Samples are inspected and shared with you for dimensional and functional verification before moving into mass production.
Aluminum Die Casting Production
During production, molten aluminum is injected into the mold cavity under high pressure and then rapidly solidified. This process enables high-volume manufacturing of accurate, repeatable parts with good surface finish and mechanical performance.
Trimming, Deburring, and Pre-Machining
After casting, runners, gates, and flash are removed through trimming and deburring. Where needed, pre-machining operations prepare parts for final precision machining or finishing.
Precision CNC Machining and Surface Finishing
Critical dimensions, sealing surfaces, and interfaces are machined to meet tighter tolerances. Surface treatments such as polishing, powder coating, or painting are then applied according to your design and performance requirements.
Final Inspection, Assembly, and Packaging
Finished parts undergo final inspection to verify that they meet the agreed specifications. We can then assemble components, label them, and pack them according to your shipping and handling requirements so that parts arrive ready for use.
