An Introduction to the Importance and Methods of Temperature Control in Rubber Extruders

What methods are used for temperature control in rubber extruders? Let me introduce them to you: typically, temperature control is implemented as a closed-loop system, following the sequence of measurement, actuator adjustment, and set-point regulation. In other words, the temperature of the controlled process must be accurately measured, the deviation from the desired setpoint identified, and the control action adjusted accordingly to maintain the target temperature. The screw of an extruder consists of two main sections: the threaded portion, which serves as the working zone, and the section that connects to the drive mechanism. Screws come in three types: single‑start, double‑start, and compound. Single‑start screws are commonly used for gel filtration, while double‑start screws are preferred for extrusion molding, ensuring uniform material discharge. Compound screws feature a single‑start thread at the feeding end (to facilitate material intake) and a different configuration at the discharge end.

The screw of an extruder consists of a threaded section—comprising the working zone—and a portion that connects to the drive mechanism. Screws come in three types: single‑start, double‑start, and compound. Single‑start screws are typically used for gel filtration, while double‑start screws are preferred for extrusion shaping, delivering uniform discharge. Compound screws feature a single‑start thread at the feeding end for easy material intake and a double‑start thread at the discharge end, ensuring even output and excellent performance.
As the applications of extruders continue to expand and extrusion theory advances, the variety of screw and thread configurations has grown accordingly, including designs such as those with primary–secondary threads, those equipped with mixing sections, and those featuring分流 (diverting) baffles, among others.
