In automotive transmissions, the shift synchronizer ring relies on friction to achieve synchronization. Applying an aluminum-molybdenum alloy coating enables self-locking functionality during gear operation, ensuring safe and smooth driving. The shift fork significantly impacts transmission shifting performance, reliability, and service life. Therefore, in product design, thermal spraying treatments such as CU-AL and NI-AL are applied to the working surface of the shift fork to enhance its wear resistance, lubrication, and fatigue strength.

During shift fork manufacturing, sandblasting the substrate surface is critical to ensure adhesion of the thermal spray coating. The sandblasted roughness profile and RA value must remain consistent, requiring stringent control over blasting angle, pressure, duration, coverage, and abrasive classification—requirements traditional sandblasting equipment cannot meet.

Responding to client needs, Paiting Technology developed a high-precision intelligent sandblasting machine for automotive components, featuring:

1. Servo manipulators for precise nozzle positioning and blasting time control.

3. Pressure-fed sandblasting with level sensors and pressure maintenance for short nozzle response time.

3. Three-stage abrasive separation and除尘: drum screening, cyclone separation, and cartridge filtration to ensure abrasive consistency.

4. Custom tooling with intelligent PLC programs enabling rapid switching between part models.

5. Broad applicability: shift forks, synchronizer rings, piston rings, brake discs, etc.

6. Equipment commissioning site
