Small-batch die casting refers to the production of parts ranging from tens to thousands of units, employing an economical and efficient die casting technology. It is typically suitable for test parts, custom parts, replacement parts, and other situations where customer orders are limited.
High-volume die casting refers to a highly automated, efficient, and low-unit-cost die casting production model for parts with an annual output typically exceeding hundreds of thousands of units. It is commonly used in the automotive industry for integrated die-cast body parts, and in consumer electronics for internal structural components.
We provide end-to-end aluminum alloy die casting solutions, covering all stages from small-batch production to mass production, focusing on integrated machining of precision die casting and surface treatment. As a Chinese die casting supplier specializing in precision manufacturing, our mission is to meet our customers' comprehensive service needs in terms of quality, cost, and delivery time during the prototype testing phase, the transition from prototype to mass production, and the mass production phase. Our core strength lies in our ability to provide die casting, precision machining, and surface treatment services for complex products (such as aluminum heat sink bodies).
The factory utilizes cold chamber die-casting machines with clamping pressures ranging from 280 to 1,600 tons, and employs standard and custom aluminum alloys such as ADC 12, A380, and AlSi9Cu3. Through vacuum-assisted and localized extrusion processes, casting thicknesses are maintained between 1.5 and 4.0 mm, with tolerances from CT6 to CT7, laying the foundation for subsequent surface treatments.
Software such as FLOW-3D CAST is used to simulate mold flow and solidification processes, optimizing the gating system and controlling porosity below 3%. This ensures the quality standards of die-cast radiator housings, a product requiring high-density materials. Our flexible production system allows for easy mold changes; for smaller orders, mold preparation can be completed within 3 to 4 weeks.
Surface finish of die-cast parts is one of our key value-added services. This includes a series of processes: blasting with 80-120 mesh aluminum sand or vibratory grinding to remove release agents and achieve a uniform surface finish. For anodized aluminum die castings, our main services include conductive anodizing and hard anodizing, with thicknesses of 3-5 μm and 25-50 μm respectively. This oxide layer passes over 500 hours of ASTM B117 neutral salt spray testing. Additionally, we offer dyeing services to meet RAL/Pantone color chart standards.
We inspect and control every step of the die casting process.
We use X-ray DR real-time imaging to detect defects, coordinate measuring machines to inspect critical dimensions, and tensile tests on stressed components.
We use eddy current thickness gauges to determine the uniformity of the anodized film thickness and determine the adhesion strength between the film and the metal using a cross-cut adhesion test (ASTM D3359); we conduct CASS or salt spray tests on anodized aluminum die castings to determine their corrosion resistance.
We can provide thermal resistance (Rth) test results for aluminum radiator housings according to ASTM D5470 standard to evaluate their heat dissipation efficiency.
