The Twin screw extrusion machine, alslo known as extruder, is widely used industrial process for producing a wide range of products from food, plastic, and chemical industries. The extrusion process is based on the principle of plasticization and homogenization of the raw material in the presence of heat and pressure. This twin screw extruder is a key component in this process as it plays a crucial role in determining the final product quality and efficiency.
A twin screw extruder are versatile equipment used to precess and extrude various materials, particularly polymers and plastics , into the desired shape and size. The twin screw extruder machine provide a efficient process for mixing, kneading, and homogenization of the material being processed, it is mainly used for test or lab research with small capacity and small batch production ,widely used in unversity &colleage lab, chemical enterprise, scientific research institution etc.
Unlike simple single screw extruder, the twin screw extruder has two parallel screws in a heated barrel . There are two kinds of configuration as the direction of rotation of the screws either corotating (both screws rotating in the same direction) or the counter-rotating (screws rotating in the opposite direction).
When the twin screws extruder working , they create a self-wiping action that prevents material buildup on the barrel walls, ensuring consistent and uniform extrusion.
This mini lab extruder machine can process all kinds of plastic ,rubber materials such as soft/hard propene Polymer (PP) and polystyrene(PE) coordinated with the appropriate auxiliary machine,it is used for processing elastomeric compound for production of rubber strips, rubber profile, rubber channels, rubber chords, rubber tubing, rubber threads etc.
Our single and twin screw extrusion machines excel in producing sheet, pellets, PVC pipe, window profiles, vinyl siding, and profiles of wood and natural fiber plastic composites.

Working Principle
The twin screw extrusion machine consists of two parallel screws that rotate in opposite directions and are housed inside the barrel. When working ,the raw material is fed into the barrel through a hopper and it is transported through the screws towards the end of the barrel. The screws are designed for compressing and heating the raw material to a specific temperature range, so that convert the raw material into a homogeneous mixture as needed. This compound mixture is then forced through a die and cooled to form the desired product. The twin screw design provides a high degree of mixing and kneading action, which enhances the plasticization and homogenization of the raw material.
Usage of Laboratory Extruders
Laboratory extruder machine are small scale production extruders with a variety of important uses:
*Small Batch Production
Laboratory extruder machine are ideal to provide the delivery and response time for low volume production.
*Product Development
This laboratory extrusion equipment also can be vital for a manufacturing company to develop new products and test new extrusion processes.
