Injection Molding Barrel Temperature Control for Resin Scorching

The patent applies local quality by setting different temperature reduction amounts for different barrel sections. The front part (prone to scorching) receives a smaller temperature reduction (first value) compared to the rear part (less prone to scorching) which receives a larger temperature reduction (second value). This localized differential temperature control prevents scorching where needed while maintaining higher temperatures in other sections to reduce restart heating time.

The patent implements local quality by applying different temperature control strategies to different barrel sections. The front part uses a smaller temperature reduction to prevent scorching, while the rear and middle parts maintain higher temperatures through larger temperature reductions. This ensures molten resin throughout the barrel remains within appropriate temperature ranges, preventing deterioration while still preventing scorching at the vulnerable front section.

The patent applies parameter changes by dynamically adjusting the temperature reduction amount based on the specific barrel section. Instead of a uniform temperature reduction, the system implements differentiated temperature reductions where the front part receives a smaller reduction (first value) and the rear part receives a larger reduction (second value). This optimized parameter adjustment reduces energy consumption during temporary stops while minimizing the impact on restart heating time.
