Rubber Extrusion

The temperature controller is a key piece of equipment for achieving precise temperature management in the rubber extrusion process. Through the synergistic effect of heating and cooling systems, it ensures that the rubber compound maintains an optimal physical state during extrusion. Its core principle lies in utilizing heat conduction and thermal convection to uniformly transfer heat to each section of the extruder (feeding section, compression section, metering section). Meanwhile, it implements closed-loop control via the PID algorithm and temperature sensors (such as PT100 platinum resistors) to dynamically adjust temperature deviations.

Preheating Stage:

Extrusion Stage:

• Control the temperature of the feeding section at 50-70°C to prevent scorching;
• Raise the temperature of the compression section to 80-100°C to build up melt pressure;
• Precisely control the temperature of the die head within ±2°C to avoid surface defects.

Cooling and Shaping Stage:
