Manufacturing process of compressor cylinder body
Jan 08,2026
The manufacturing of compressor cylinder body requires multiple processes to ensure dimensional accuracy and surface quality:
casting
Sand casting: Low cost, suitable for large-scale production, but with lower surface accuracy.
Precision casting: such as investment casting, can produce high-precision and complex structure cylinder bodies.
processing
Honing machining: The inner wall of the cylinder body is machined with a second level precision, resulting in low surface roughness and reduced friction and wear.
Numerical Control Machining: Used for machining complex structures such as airways and waterways on cylinder bodies.
heat treatment
Quenching+tempering: Improve the strength and hardness of the cylinder body, eliminate internal stress.
surface treatment
Coating treatment: such as sandblasting and polishing, to enhance surface hardness and corrosion resistance.
Water jacket or heat sink: A water jacket or heat sink is installed on the outer wall of the cylinder body to enhance the cooling effect.

Application scenarios of compressor front cover
Automotive air conditioning compressor: In automotive air conditioning systems, the front cover of the compressor needs to be lightweight, corrosion-resistant, and have good heat dissipation performance to adapt to the narrow space and harsh environment inside the car.
Structure type of compressor front cover
Integral front cover: It is cast or machined as a whole with the compressor cylinder or shell, with a compact structure, suitable for small compressors. This structure helps reduce the number of parts and improve assembly efficiency.
