Industrial Applications

1. Plastic Injection Molding Die Temperature Regulation

After opening the molding die tool and ejecting the plastic part, the temperature decreases rapidly. The E5CWL-R1TC uses its fast 250 ms sampling time and 2-PID control with auto-tuning to quickly restore the die to stable thermal conditions without overshooting.

Problem Solved

Prevents temperature fluctuations that cause warping, material degradation, or inconsistent curing in plastic parts during short injection cycles.

2. Industrial Packaging and Sealing Machines

In high-speed packaging, heat is drawn away from the sealing jaws every time they clamp onto a product. The compact 1/16 DIN controller actively monitors the temperature drop via a thermocouple and switches the 250VAC 3A relay output to instantly drive the heating elements.

Problem Solved

Eliminates weak, inconsistent, or melted seals by instantly reacting to thermal drops with rapid sampling and precise relay actuation.

3. Thermal Stability in Laboratory Ovens

Maintaining precise internal temperatures for stress-testing components is critical. The controller utilizes its high ±0.5% indication accuracy and dual LED display to monitor the Process Value, driving heating elements smoothly via its PID algorithm to maintain strict thermal boundaries.

Problem Solved

Resolves imprecise heating controls and severe overshoot issues in testing chambers, ensuring highly repeatable and compliant testing environments.
