News Release: STMC Sets New Standard for PPS Injection Molded Part Finishing with Advanced Cryogenic Deflashing Technology

PPS, a high-performance engineering plastic valued for its excellent heat resistance, chemical resistance, and mechanical strength, is widely used in manufacturing precision components for automotive, electronics, aerospace, and other industries. However, its high rigidity and strength make the flash and burrs formed after injection molding particularly difficult to remove. T

STMC’s cryogenic deflashing technology presents a revolutionary solution to this industry challenge. The process utilizes ultra-low temperatures (down to -120°C and below) generated by liquid nitrogen or compressed air to rapidly embrittle the flash and burrs on the surface of PPS components. Subsequently, these embrittled residues are instantly removed by blasting with soft media particles, achieving a precise, efficient, and non-destructive cleaning process.

Core Advantages of STMC’s Cryogenic Deflashing Technology

Whether utilized as a service or delivered as equipment, STMC’s technology offers these core advantages:

1. Exceptional Precision and Part Integrity: Precisely removes micron-level burrs without damaging the part’s critical dimensions or structure, especially suited for high-tolerance PPS components like gears, connectors, and sensors.

2. Comprehensive Coverage: Effectively cleans complex features inaccessible to traditional tools, such as internal holes, threads, and cross-holes.

3. Significant Cost-Efficiency: High batch processing capacity and fully automated operation can replace multiple skilled workers, drastically reducing overall production costs.

4. Environmentally Friendly Process: A chemical-free operation using recyclable media, aligning with modern clean production standards.
