Anebon shares these integration advantages while differentiating through its combined strength in CNC machining, die casting, and sheet metal fabrication for OEM assemblies.

Die Casting Processes Used by Leading Chinese Aluminum Foundries

Chinese aluminum foundries employ several metal casting process types. Here is how they differ and when each applies.

High-pressure die casting (HPDC) is the dominant die casting process for complex, thin-walled components. It uses high pressure to force molten metal – specifically molten aluminum – into a die cavity at high speed. Die casting uses high pressure to inject molten metal, producing aluminum die casting parts with excellent dimensional accuracy and smooth surfaces. High-pressure die casting is fast and cost-effective for mass production, with cycle times often under 60 seconds for small-to-medium parts. Die casting is suitable for mass production of small parts as well as medium sized castings.

Low pressure casting and gravity die casting are used for larger, thicker-walled parts that require high integrity and lower porosity – applications such as wheels, specific structural parts, or power tools housings. These production processes sacrifice cycle speed for improved mechanical properties.

Aluminum die casting involves processes such as hot-chamber and cold-chamber casting methods, but for aluminum specifically, Chinese companies primarily use cold chamber die casting. Cold chamber die casting is used for high melting point metals like aluminum (melting point ~660 °C), whereas hot chamber die casting is reserved for lower-melting alloys like zinc. In a cold chamber machine, molten aluminum is ladled into the shot sleeve before each cycle, then a piston forces the metal into the mold cavity.

Die casting is rarely the final step and often includes secondary operations like CNC machining for tight-tolerance features. Advanced Chinese die casting services integrate simulation, optimized gating, and process monitoring to minimize porosity, cold shuts, and other common defects. Common challenges in die casting include managing porosity and maintaining dimensional tolerances – problems that experienced suppliers address through vacuum assist, overflow design, and real-time process control.

Die casting can create complex shapes with smooth surfaces, and it can produce complex shapes with high dimensional accuracy, which is why OEMs across industries rely on it. For comparison, other methods like sand casting, lost wax casting (investment casting), and injection molding serve different niches in terms of volume, precision, and cost.

Aluminum Alloys, Casting Equipment & Surface Treatment Capabilities

Understanding material specifications is important for achieving desired mechanical properties in die casting. The most common aluminum alloys used by top Chinese die casters include:

Alloy	Key Properties	Typical Applications
A380	Excellent fluidity, good strength, widely available	General-purpose: housings, brackets, motor housings
A383	Provides precise die filling capabilities, good for thin walls	Complex thin wall parts, electronic components
A360	Offers high corrosion resistance and pressure tightness	Fluid-handling parts, outdoor enclosures
ADC12	Similar to A383, popular in Asia-Pacific markets	Automotive, industrial equipment

A380 aluminum alloy is commonly used for die casting due to its balanced performance. Aluminum alloys are favored for automotive and industrial applications because aluminum die cast parts have high thermal and electrical conductivity alongside good corrosion resistance.

Casting equipment at leading factories typically includes multiple cold chamber machines ranging from 160 T to 2,500 T (and beyond for gigacasting), robotic ladling systems, real-time monitoring, and in-house melting and holding furnaces. Heat treatment and squeeze casting capability may also be available for parts requiring enhanced mechanical properties.

Surface treatment options that top companies provide include anodizing, powder coating, electrophoretic coating, electroplating, polishing, bead blasting, and painting. These surface treatments improve corrosion resistance, wear resistance, and aesthetics. Part design – including radii, wall thickness, and cosmetic zones – directly affects surface finishing results and cost. OEMs should verify whether a supplier controls key surface treatments in-house or partners with certified finishing vendors, as this impacts stable quality and lead times.

Case Applications: Where Chinese Aluminum Die Casting Excels

Chinese aluminum die casting serves a wide range of application areas: automotive, telecom, medical devices, industrial automation, robotics, lighting, and consumer electronics.

Automotive: Large structural castings such as battery tray components and EV chassis parts are produced by groups like Wencan and Guangdong Hongtu using high-pressure casting on mega-tonnage machines. These parts demand fatigue resistance, weldability, and dimensional stability across thousands of units. Excess material is removed through precision trimming and CNC machining before assembly.

Electronics and telecom: Precision heat sinks, enclosures, and EMI-shielding housings are manufactured by mid-size companies like Sunrise Metal and Anebon with tight-tolerance CNC finishing. These parts require good thermal conductivity, thin walls, and excellent surface finishing – areas where die casting CNC machining integration is essential.

Industrial machinery and robotics: Gear housings, motor brackets, and frames combining aluminum die cast and machined features are produced by integrated suppliers in Dongguan and Ningbo. These parts often involve heavy ribs, mounting interfaces, and sometimes leak-path testing.

Choosing the right partner by industry focus and casting process capability reduces risk and speeds up time-to-market.

Trends Shaping Aluminum Die Casting Companies in China (2024–2026)

China’s aluminum die casting industry is evolving rapidly across several fronts.

Automation and digitalization: Robots for ladling, trimming, and part extraction are now standard at top factories. MES systems enable real-time data for process control and traceability from melt to finished part. Wencan operates over 600 industrial robots and automated storage systems.

NEVs and lightweighting: Demand for larger integrated aluminum die castings continues to surge. Higher-tonnage machines and new alloys suited to high-strength structural parts are being deployed. Gigacasting – producing large structural castings that replace dozens of stamped and welded parts – is reshaping how OEMs think about vehicle architecture.

Sustainability: Higher use of secondary aluminum, energy-efficient melting furnaces, and scrap recycling programs are becoming standard. ISO 14001 environmental management is now expected by major OEMs, and Anebon holds this certification.

For overseas buyers, these trends mean more capacity for complex aluminum die cast projects and shorter lead times. But they also raise the bar: you need to partner with a trusted die casting supplier that can keep up with rapid design changes and tightening environmental standards.
