Rubber extruders are machines designed to shape raw rubber into specific profiles or forms, often used in the production of rubber goods like seals, gaskets, hoses, tires, and belts. The extruding process involves forcing rubber through a die to create uniform profiles, and these machines are integral to ensuring consistency and high-quality production.

Historically, rubber processing was a labor-intensive and time-consuming task that required immense manual effort. However, the introduction of modern rubber extruders has streamlined this process, improving efficiency, precision, and output.

The 150mm16D/20D Cold Feed Rubber Extruder is a type of rubber extruder designed for processing and shaping rubber compounds under controlled conditions. The "150mm" refers to the extruder's screw diameter, which is crucial for determining its capacity and ability to handle different types of rubber materials. Meanwhile, the "16D/20D" indicates the L/D ratio of the screw–specifically, the length of the screw compared to its diameter. These numbers reflect the extruder's ability to handle varying levels of viscosity and different types of rubber.

What sets the 150mm16D/20D Cold Feed Rubber Extruder apart from other extruders is its innovative design and technological advancements that enhance performance, efficiency, and versatility in production.

One of the defining features of the 150mm16D/20D Cold Feed Rubber Extruder is its cold feed mechanism. Unlike hot feed extruders, which require heat to soften the rubber before it is fed into the extruder, cold feed extruders work with unheated, raw rubber. This not only helps to preserve the integrity of the rubber's physical properties but also reduces the risk of premature curing. Cold feed extruders are particularly advantageous for producing a range of rubber compounds, especially those that are sensitive to heat and require precise temperature control.

The system adopts forced circulation of media, and controls the temperature of each section independently in six units. Each unit is composed of a water pump, an electric heater, a temperature control instrument, a cooling water on-off solenoid valve, an automatic exhaust valve, a platinum thermal resistance, and an electrical contact pressure.
