In earlier versions, 16D was the standard length, offering reliable extrusion for basic applications. However, as rubber formulations became more sophisticated and end-product requirements more demanding, there was a need for greater control over material behavior within the extruder. This led to the development of 20D screws, which provide extended mixing and refining capabilities, enabling manufacturers to achieve improved product uniformity and surface quality.

Factors Driving Development

Several key factors have contributed to the ongoing evolution of the 150mm 16D/20D cold feed rubber extruder:

Market Demand for Higher Quality Products

Automotive, aerospace, and industrial sectors increasingly require rubber products with precise tolerances and consistent mechanical properties. This demand has driven refinements in screw design, temperature control, and die configurations.

Improved Energy Efficiency

Energy consumption remains a major consideration in industrial manufacturing. Newer designs of the 150mm extruder feature optimized screw profiles and barrel materials to reduce friction and improve heat management, resulting in lower overall energy usage.

Advanced Control Systems

Modern extruders now incorporate sophisticated control systems, including programmable logic controllers (PLCs) and touchscreen interfaces. These advancements allow for more precise control over processing parameters such as screw speed, temperature zones, and pressure. The result is enhanced repeatability and reduced scrap rates.

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. Table (shockproof) and other components, the circulating water pump injects the medium (softened water) into the electric heater (the automatic exhaust valve discharges the gas in the system), flowsthrough the barrel, pipeline, the machine head, and the screw return to the suction port of the pump.
