Small Precision Extrusion Casting Test Line

Small Precision Extrusion Casting Test Line

FDSI-22
The small precision extrusion casting experimental line consists of a precision single screw extruder, a set of casting die head, and a set of precision casting auxiliary machine set, which can realize all functions of screw plasticizing extrusion, casting, traction, edge cutting, winding, and edge collection of a casting line; the split structure is easy to carry and move, and the integrated design is easy to use and operate, which can greatly improve the experimental efficiency and shorten the product development cycle. It is an ideal experimental equipment for polymer material casting molding.
