Custom Die Casting Parts Manufacturer Provide OEM Metal Casting Solutions
China OEM die casting manufacturer offers zinc hot chamber die casting and cold chamber aluminum die casting services for a wide range of industrial applications. We focus on versatility sized precision metal die casting parts. Including high-precision electrical components and high-strength mechanical components,high wear resistance automotive components, medical device housing and enclosures and precision communication equipment components.
Custom Engineering Design
Engineers prepare different Design for Manufacturability (DFM) assessment reports based on the selected die casting material, as each alloy requires a unique tooling and manufacturing strategy. Material properties directly influence mold design, gating and cooling systems, machining requirements, production efficiency, and the overall tooling investment.
Tooling manufacturing, production stability, and mold service life are major factors affecting a customer’s initial investment and long-term manufacturing costs. Different die casting materials operate at different casting temperatures, thermal loads, and cycle conditions. These variations significantly impact mold wear, thermal fatigue, cooling performance, and maintenance frequency. Consequently, mold optimization, preventive maintenance, repair costs, and tooling lifespan differ between zinc hot chamber die casting and aluminum cold chamber die casting processes.
Die Casting Tooling and Manufacturing And FAI Strategy
Premium-grade tooling steel is carefully selected and precision machined into a high-performance die casting mold using advanced CNC machining centers, surface grinding machines, wire EDM, and sinker EDM equipment. Every mold component—including the core, cavity, inserts, sliders, ejector system, cooling channels, and gating system—is manufactured to strict dimensional tolerances and thoroughly inspected before assembly.
After all mold components are completed, experienced mold technicians assemble the die, verify the alignment of the two mold halves, and install the finished die onto the die casting machine. The mold is then accurately aligned, securely clamped, and connected to the cooling and hydraulic systems before trial production begins. This careful setup ensures stable operation, precise part dimensions, and consistent casting quality throughout mass production.
Before mass production begins, a First Article Inspection (FAI) is conducted to verify that the tooling, die casting process, and finished components meet all engineering specifications and quality requirements. During trial casting, engineers and mold technicians carefully record critical process parameters, including molten metal temperature, die preheating temperature, injection speed, injection pressure, holding pressure, cooling time, and overall casting cycle time.
If casting defects such as porosity, shrinkage, flash, cold shuts, or dimensional deviations are detected, the engineering team analyzes the root causes and continuously optimizes the mold design and die casting parameters. Trial production continues until qualified samples consistently satisfy the required dimensional tolerances, surface quality, and mechanical performance.
After successful validation, a comprehensive First Article Inspection (FAI) report is prepared, including dimensional measurement results, material certification, process parameters, and inspection records. The approved first article sample, together with the FAI report, is then submitted to the customer for evaluation and formal approval. Once customer approval is obtained, the project proceeds to stable, high-volume mass production.
