Product Description:

1. Use a screw of a specific shape to rotate in a heated barrel, and the plastic sent from the hopper is squeezed forward, so that the plastic is evenly plasticized (ie melted), and the plastic is squeezed through the head and molds of different shapes.

2. In the plastic extrusion process, the plastic insulation and sheath of the wire and cable are carried out by continuous extrusion. The extrusion equipment is generally a single-screw extruder. Before the plastic is extruded, it is necessary to check in advance whether the plastic is wet or whether there is Other debris, then preheat the plastic and add it to the hopper

3. During the extrusion process, the plastic enters the barrel by gravity or reaches the feeding screw, and continuously advances under the inference of the rotating screw, starting from the preheating section and gradually moving to the homogenization section. At the same time, the plastic is stirred and squeezed by the screw, and is transformed into a viscous flow state under the action of the shear friction heat between the external heat of the barrel and the equipment, forming a continuous and uniform flow in the screw groove.

4. Plastic extrusion is mainly based on the plastic state of plastic. The plastic molding process of plastic in the extruder is a complex physical process: including mixing, crushing, melting, plasticizing, venting, compacting and final molding and shaping, this process is realized continuously. Plasticization stage (mixing, melting and homogenization of plastics) molding stage (extrusion molding of plastics) shaping stage (cooling and solidification of plastic layers)

Our machine compare other factory advantages:

1.Our squeezing machine can adjust the final product size as customer require, can adjust different capacity! The final product has semi-plastization and full-plastization!

2.Different screws and barrel ,Our screw L/D is 6:1, and other factory is L/D is 4:1 , for example diameter 350mm screw, length is 2100mm. if L/D:4:1, the length is 1400mm.

Why we choose L/D is 6:1 ,not 4:1. Because It is very import to material!

3.Our electric control box has big space!!! The space is large enough, the control cabinet is easier to dissipate heat, and the equipment runs more stable!
