STMC: Precision Deflashing for Electric Vehicles

As the EV industry grows, part manufacturing demands higher precision. STMC, a leader in cryogenic deflashing machines, uses its technical expertise to help EV manufacturers achieve precision at scale for rubber, plastic, and zinc alloy parts.

Covers Key EV Components

STMC’s technology works across a wide range of EV parts:

- Door buffers(rubber/plastic): Burr-free for precise assembly.
- Charging components (elastomer sleeves, zinc alloy heads): High surface quality and accuracy.
- Seals & gaskets (rubber): Critical for battery packs, requiring flawless edges.
- Camera housings(precision plastic): Consistent, non-destructive deflashing for complex shapes.
- Bushings & dampers(rubber/plastic): High-precision batch processing.

The process uses liquid nitrogen to embrittle flash, which is then blasted away without damaging the part.

Precision & Efficiency Combined

Cryogenic deflashing outperforms manual methods:

- Micro-level precision: Down to micron accuracy.
- High output: One STMC machine replaces 60-80 manual workers.
- 98%+ yield:Consistently high quality.
- Fast changeover: One-click switching between products.

Trusted by Top EV Brands

STMC’s reliable performance has earned it a place in leading EV supply chains, with over 15% market share in 2024. Tesla engineers have also validated STMC machines at its Shanghai factory for silicone parts.
