CNC machined ADC 12 aluminum high pressure casting piston with shot blasting

This precision-engineered aluminum piston combines advanced manufacturing techniques and high-performance materials to deliver exceptional durability, precision, and efficiency in demanding mechanical applications.

Material: ADC 12 Aluminum Alloy
High Strength & Lightweight: Optimizes power-to-weight ratios, reducing inertial losses in high-speed systems.
Excellent Castability: Ensures complex geometries and thin-walled structures are achievable with minimal defects.
Thermal Stability: Maintains dimensional integrity under high-temperature operating conditions.
High-Pressure Die Casting (HPDC): Produces near-net-shape pistons with tight dimensional tolerances, enhanced density, and reduced porosity for superior structural integrity.
CNC Machining: Post-casting precision machining guarantees critical features (e.g., bore holes, grooves, sealing surfaces) meet exact specifications (±0.02 mm). Ensures compatibility with engine blocks, hydraulic systems, or pneumatic assemblies.
Surface Treatment: Shot Blasting
Enhanced Surface Hardness: Improves wear resistance and fatigue life by inducing compressive stress on the piston surface.
Deburring & Cleaning: Removes casting residues and micro-imperfections, preparing the surface for coatings or further finishing.
Uniform Texture: Creates a matte finish that improves lubricant retention and reduces friction.

The application status of aluminum die casting in compressors ‌ is mainly reflected in its superior performance and a wide range of application fields.cnc machined die castings Aluminum die casting plays an important role in compressor manufacturing because of its light weight, corrosion resistance, high strength and other characteristics.

Aluminum die castings are widely used in compressors, especially in automotive air conditioning compressors, and the use of aluminum die castings is particularly common. For example:


‌Automotive air conditioning compressor: Aluminum alloy die-cast parts are widely used in automotive air conditioning compressor, mainly used in the manufacture of compressor shell, valve plate, piston and other key components. These components need to withstand high temperature and pressure working environments, aluminum alloy's high strength and corrosion resistance make it an ideal material ‌


‌Household appliance compressor: In household appliances such as refrigerators, air conditioners and other compressors, aluminum alloy die casting also occupies an important position, mainly used in the manufacture of shell, bracket and other parts to reduce weight and improve efficiency ‌

Product Advantages of  CNC machined aluminum high pressure casting piston:


  • High Load Capacity: Withstands extreme pressures in combustion engines, compressors, or hydraulic systems.

  • Corrosion Resistance: ADC 12 aluminum inherently resists oxidation, while shot blasting adds a protective surface layer.

  • Reduced Friction: Precision-machined surfaces and shot-blasted texture minimize energy losses and heat generation.

  • Extended Service Life: Resilient to thermal cycling, abrasion, and mechanical stress in repetitive motion applications.

  • Cost-Effective Production: HPDC minimizes material waste, while CNC machining ensures quality consistency.

  • Customizable: Adaptable to specific design requirements (e.g., coatings, anodizing, or custom dimensions).

  • Sustainability: ADC 12 aluminum is fully recyclable, aligning with eco-conscious manufacturing practices.

  • Excellent Thermal Conductivity: Efficiently dissipates heat, minimizing thermal expansion and ensuring stable performance in high-temperature environments.

  • Improved Lubricant Retention: The textured finish from shot blasting reduces friction by retaining oil or grease, optimizing efficiency in dynamic systems.




Product Use of CNC machined aluminum high pressure casting piston:



  • Automotive Systems: Ideal for lightweight engine pistons, transmission components, or braking systems.

  • Hydraulic/Pneumatic Equipment: Used in pumps, cylinders, or actuators requiring high-pressure tolerance.

  • Industrial Machinery: Suitable for compressors, presses, and automated systems demanding precision and durability.

  • Aerospace & Marine: Corrosion-resistant properties make it viable for auxiliary systems in harsh environments.
