Recently, STMC received a special “test case”—a sample zinc alloy toy car from an overseas client. The challenge was clear: address the problematic flashing, particularly along the parting lines and gate areas. The client’s goal was to find a high-efficiency, non-destructive finishing solution. STMC accepted the challenge and delivered a perfect result: we utilized our self-developed Cryogenic Deflashing Machine, designed specifically for zinc alloys, to provide expert contract processing services.
This was more than just a standard processing job; it was a live demonstration of our equipment’s capabilities. As the manufacturer of the machine, STMC knows that the most powerful testimony is a flawless finished product achieved with our own technology. Leveraging our deep understanding of the machine’s performance, we precisely set the process parameters. The toy car was exposed to ultra-low temperatures (below -80°C), instantly embrittling the flashes, which were then removed by high-speed media bombardment—resulting in a smooth, clean, and perfectly intact product.
