locking pin
The locking pin (or mold locking pin) is a hardened, precision-engineered component that secures the two halves of the blow mold in perfect alignment during the blowing process. It ensures the mold remains tightly closed under high-pressure air injection (up to 40 bar) to prevent flash (excess plastic), leaks, or misalignment that could compromise bottle quality. This part is essential for maintaining production consistency and safety in high-speed Sidel machines.
