A crucial component of a plastic thermoforming machine is its main unit. Let's take a closer look! In plastic thermoforming equipment, the plastic extruder is usually referred to as the main unit, while the subsequent equipment, the plastic extrusion molding machine, is called the auxiliary machine. After more than 100 years of development, plastic extruders have evolved from the original single-screw type to various models such as twin-screw, multi-screw, and even screwless extruders. The plastic extruder (main unit) can be matched with various auxiliary plastic molding machines for pipes, films, rods, monofilaments, flat filaments, strapping, extruded mesh, sheets, profiles, granulation, cable sheathing, etc., to form various plastic extrusion molding production lines to produce a variety of plastic products. Therefore, plastic extrusion molding machinery is one of the most widely used types of machinery in the plastics processing industry.
