This machine is a twin-screw extruder, and the granulator unit consists of an extruder, a cold water tank, and a granulator combination
1、 Equipment Overview:
*This machine is suitable for mixing, plasticizing, and extrusion processing experiments of engineering plastics, modified plastics, and color masterbatch. It has functions such as plasticizing homogenization, coloring and sampling, and filling modification.
*Specially manufactured screws and barrels with high processing accuracy and quality assurance
*Brand motor drive, stable and reliable screw speed control
*The material with adjustable particle size and thickness is fully plasticized and mixed in the screw.
*This product uses household 220V voltage, adjustable extrusion speed, and extrusion temperature can be set arbitrarily between room temperature and 400 degrees.
*The height of the extrusion center is 300MM, and the maximum output for ABS material is around 0.8KG-3KG per hour.
*This machine is a twin-screw extruder
2、 Application scope of laboratory small single screw extruder:
*Melting, plasticizing, and extrusion of materials
*Optimization of extrusion molding process parameters
*Establish small-scale experimental lines for films, sheets, pipes, granulation, etc
3、 Machine principle
The principle of this machine is to feed plastic particle raw materials into a hopper, melt them through a screw heating zone, rotate and extrude them, and use an extrusion hole mold to squeeze out the melted plastic. Then, other auxiliary processes such as cooling, traction, and winding are used to make the required product size.
