plastic recycling pelletizing machines head role and classification
plastic recycling pelletizing machines include extrusion die head and fixed mold in two parts.
1. The role of the head of
The extrusion head is the main component parts of sodium molding material, which allows the molten plastic from the extruder by the helical motion into linear motion, and further gradually oriented, to generate the necessary molding pressure to ensure the compacting of plastic parts, whereby the cross-sectional the shape is similar to the continuous profiles.
2. The role of stereotypes die
From the head of the extruded plastic parts, although with a given shape, but because the workpiece temperature is relatively high, due to the weight and deform, so need to use the shape of the workpiece sizing device for cooling stereotypes, to obtain energy meet the requirements of the correct size, geometry and surface quality. Usually cooling, pressure or vacuum methods, die in a predetermined shape from a plastic extruded stabilized, and its finishing to obtain a more accurate cross-sectional dimension, a more shiny surface lance feed system pieces.
3. The head of classification
(1) Press the extruded plastic parts classification
Extruded plastic parts usually have tubes, rods, plates, sheets, webs, monofilament, pellets, a variety of different profiles, blown film, wire and cable, pipe used in the nose called a nose, respectively, rods handpiece.
(2) the direction of exports by product classification
Can be divided into vertical and horizontal head nose. The former head of the stream in the direction consistent with the extruder screw axis, such as a hard tube head; the latter in the direction of the stream head extruder suspected axial rod at an angle, such as cable head.
(3) by the pressure inside the head size classification
Can be divided into low head (stream pressure is less than 4MPa), the press head (stream pressure 4MPa-lOMPa) and high-pressure head (stream pressure greater than lOMPa).
