Recently, STMC nailed it by using their in-house developed dual-wheel cryogenic deflashing machine to handle a massive order of card reader casings. These parts needed super precise edges, and the machine delivered a killer 98% success rate—way above the client’s tough standards.
The casings are made of ABS plastic, and their complex shape made traditional deflashing methods a no-go. That’s where STMC’s dual-wheel cryogenic machine came in. Built back in 2015, this beast was designed for high-precision jobs. Its twin-wheel setup blasts media evenly across the parts, shaving off rough edges without messing up the surface.
Here’s how they did it: First, every part got checked for defects—only the good ones moved forward. Then, workers loaded them into custom fixtures on the machine’s gearbox. Once the door shut, the wheels spun up, hurling media at high speed to clean up the edges. The fixtures rotated with the gearbox, making sure every angle got hit evenly. Ten minutes later—boom—job done. Open the door, and out came perfectly finished parts.
Compared to old-school methods, cryogenic deflashing is faster, more precise, and way gentler on the parts. For big batches with tight tolerances, it’s a game-changer, slashing production time and costs. STMC’s success with these card reader casings proves they’ve got serious skills in precision manufacturing—and gives other companies in the field a solid blueprint to follow.
Looking ahead, STMC plans to keep pushing R&D to make their cryogenic tech even better, so they can tackle more high-stakes jobs across different industries.
