Product Overview
The Automotive Compressor Swing Arm, also known as a control lever arm in some designs, is a motion-control component used in automotive air conditioning compressors. In compatible variable displacement compressor mechanisms, it helps transmit mechanical movement associated with swash plate adjustment. Its geometry, pivot interfaces, and dimensional accuracy can affect the consistency of movement within the compressor assembly.
Sangroove (Jiangsu) Machinery Co., Ltd. manufactures customized compressor swing arms for automotive HVAC applications. Our production capabilities include tooling development, casting, heat treatment, CNC precision machining, and dimensional inspection. QT600 ductile iron is the listed main material, while 45# steel, 40Cr, and custom alloy materials can be evaluated according to project requirements.
For compressor manufacturers and component suppliers, we support drawing-based production with defined requirements for critical dimensions, hardness, and surface protection. The manufacturing process and inspection plan can be tailored to the component design, intended operating conditions, and agreed quality standards.
