Product Overview
The Automotive Compressor Swash Plate Seat is a supporting and positioning component within an automotive air conditioning compressor. It provides a designated mounting interface for the swash plate assembly and helps maintain the required relationship between connected components during operation. Its geometry, fit, and dimensional consistency are important to assembly alignment and the movement of the compressor mechanism.
Sangroove (Jiangsu) Machinery Co., Ltd. manufactures customized swash plate seats using casting and precision machining processes. QT600 ductile iron is the listed main material, while 45# steel, 40Cr, and customized alloy materials can be considered according to the project specification. Manufacturing may include tooling development, casting, heat treatment, CNC machining, and final dimensional inspection.
For compressor manufacturers and component suppliers, production can be organized around customer drawings and defined quality requirements. Critical mounting dimensions, material properties, hardness, and surface protection can be specified according to the compressor design and intended operating conditions.

Manufacturing Process
Drawing Review and Tooling Development – Review the seat geometry, mounting interfaces, and machining allowances.
Casting Process Selection – Evaluate lost foam, shell mold, resin sand, or green sand casting according to the component design.
Induction Melting and Composition Control – Manage material composition according to the specified grade.
Casting Quality Inspection – Check the cast blank for relevant defects before further processing.
Heat Treatment – Apply quenching, tempering, or stress relief as required by the technical specification.
CNC Precision Machining – Finish designated mounting surfaces, bores, and other critical features according to the drawing.
Surface Protection – Apply anti-rust oil, E-coating, or phosphating where specified.
Final Dimensional Inspection – Verify critical dimensions and other agreed quality characteristics before delivery.
