Conventional heat treating process for trim dies involved leaving an extra stock of material on the die, which was then subjected to induction or flame heat treating. After heat treatment, the dies were machined back to the required tolerances. While this approach had been employed for many years, it presented several challenges and limitations. One of the primary drawbacks of the conventional process was the need to machine the dies after heat treatment. This added extra time, cost, and complexity to the production process, reducing overall efficiency.
While laser heat treating offered numerous advantages, applying it to trim edges presented a unique set of challenges. One of the key difficulties was the potential for edge rolling or melting during the heat treating process. Achieving uniform heat distribution without compromising the structural and dimensional integrity of the dies required a comprehensive and precise approach.
Synergy’s Innovation: Multi-Point Temperature Control System (MPTC)
Synergy’s commitment to overcoming challenges led to the development of the Multi-Point Temperature Control System (MPTC). This groundbreaking system enables Synergy to regulate laser power and temperature distribution over the entire trim edge, ensuring consistent and controlled heat treatment without causing edge rolling or melting.
