Precision Aluminum Alloy Die Casting Mold with CNC Machining China Service

As a mold technician, I will professionally introduce aluminum alloy die casting molds. These are specialized tools used to inject molten aluminum alloy into mold cavities, cooling and solidifying to obtain parts with desired shapes. Depending on casting characteristics, we select hot-chamber die casting molds (for lower melting point alloys) or cold-chamber die casting molds (for larger components). Our molds are developed using CAD/UG/Proe technologies combined with advanced CNC machining, ensuring precision up to 0.01mm.

In modern manufacturing, die casting mold quality directly determines final product dimensional accuracy and internal quality. We ensure smooth filling of aluminum alloy melt through optimized gating system design, reducing porosity and defects; control mold temperature through efficient cooling systems to shorten production cycles; and eliminate cavity gases through scientific venting systems to enhance casting density.

• High Precision and Stability: Our aluminum alloy die casting molds use premium mold steels (like H13, SKD61) with excellent wear resistance, heat resistance, and strength. During design phase, CAE analysis (e.g., AnyCasting software) simulates filling process to optimize gating and venting systems. Manufacturing employs CNC machining centers, EDM, and wire-cut machines to maintain cavity accuracy consistently within 0.01mm. Multi-cavity designs and precisely calculated parting surfaces ensure batch production consistency.
• Long Life and Reliability: Through scientific mold design and heat treatment processes, our mold lifespan is significantly improved. For instance, applying additive manufacturing to incorporate conformal cooling channels in slider inserts increased mold life from 3,000 to 15,000 shots. Mold cavity surfaces undergo nitriding treatment to enhance corrosion resistance, suitable for high-temperature aluminum die casting environments. Fixed mold installation ensures stability and safety during production.
• High Efficiency and Flexibility: Our molds support multi-cavity layouts, compatible with 160-800 ton die casting machines, achieving annual production capacity up to 1 million pieces. Tree-style runner systems with precisely calculated gate cross-sectional areas (e.g., 170mm² for camera housing molds) optimize filling effects. Designs consider production efficiency, such as applying curved parting surfaces to resolve complex part ejection, eliminating loose pieces and shortening cycles.
• Comprehensive Quality Control: We implement full-process quality monitoring from material intake to mold delivery. Conducting material composition inspection, dimensional checks, appearance examination, and mechanical performance tests, with X-ray inspection for internal defects when necessary. Molds strictly adhere to ISO9001 quality system standards, ensuring compliance at each stage. Actual trial runs validate mold performance, with optimizations based on feedback.
