Why are Screw-Type Air Compressor Head Castings Preferably Manufactured Using High-Strength Green Sand Casting?

Superior Vibration Damping and Material Density

Screw-type air compressor heads require exceptional structural integrity and vibration absorption to ensure the long-term stability of the rotors. High-strength green sand casting is preferred because it allows for the efficient production of high-grade gray iron (such as HT250/300) and ductile iron, which provide the natural damping properties needed to reduce noise and mechanical wear.

Anhui Shixuan Machinery Technology Co., Ltd., with its 18,000-square-meter facility and professional R&D team, specializes in optimizing these material properties. By utilizing advanced green sand molding, we ensure that the castings for air compressor parts possess the necessary dense microstructure to withstand internal pressures and operational stresses.

  • Mechanical Strength: Our process ensures that castings within the 0.5 kg to 80 kg range maintain high tensile strength and hardness.
  • Internal Soundness: Through precise mold design at our engineering technology R&D center, we eliminate micro-porosity, which is critical for the "pressure sealing" requirements of screw-type housings.
  • Cost-Efficiency for High Volume: With an annual capacity of 100,000 tons, green sand casting offers the most competitive cost-to-quality ratio for mass-produced air compressor components.

Technical Parameter Comparison for Air Compressor Castings

The table below highlights why optimized green sand parameters at Anhui Shixuan Machinery Technology Co., Ltd. are ideal for Screw-Type Air Compressor Castings- Green Sand Casting:

Technical Indicator Standard Green Sand Shixuan High-Strength Green Sand Requirement for Screw Compressors
