What are the characteristics of the elastomer extruder?

China's blow molding machine industry gradually plays the word ah plastic industry concern is increasing day by day, the demand for extrusion machines gradually transformed into energy-efficient, high output base blow molding machines. elastomer extruder as important equipment for plastic molding also has a very important role in the rubber industry. It conveys, compacts, melts, shears, and mixes the extrusion of the material through external power transmission and heat transfer from external heating elements. So, what are the characteristics of an elastomer extruder?

Principle of elastomer extruder

Extrusion equipment is constantly being improved and perfected. During operation, heating, pressurization, and shearing are used to convert the solid material body into a uniform and consistent melt, which is sent to the next process of melt production involves mixing additives such as masterbatch, blending resins, and re-crushing. The finished melt must be homogeneous in consistency and temperature. The pressurization must be high enough to extrude the viscous polymer

Features of elastomer extruder

The extruder does all of this through a barrel with a screw and auger. The pellets enter the barrel through a hopper at one end of the barrel and are then transferred through the screw to the other end of the barrel. In order to have sufficient pressure, the depth of the threads on the screw decreases with increasing distance to the hopper. The external heating and the internal heat generated in the plastic and the screw due to friction soften and melt the plastic. Generally, different polymers have different applications, and elastomer extruders are designed to have discharge ports, multiple loading ports, special mixing devices along the screw, cooling and heating of the melt, external heat sources, the relative size of the gap change between the screw and the barrel, and the number of screws. For example, twin-screw elastomer extruders allow for more adequate mixing of the melt compared to single-screw elastomer extruders. Tandem extrusion uses the melt-extruded from the first elastomer extruder as feedstock for a second elastomer extruder, typically used to produce extruded polyethylene foam.

Advantages of plastic recycling twin-screw extruder compared with a single-screw extruder

Higher production capacity.

Energy and time savings due to the elimination of pre-drying and crystallization.

Superior quality of the final product, which does not turn yellow.

High flexibility, because the plastic recycling twin-screw extruder has good self-cleaning properties and can change formulation and color very quickly.

Simpler logistics, because the new product in granular form and the different recycled products can be processed together.
