The hob of Meissen glass fiber pelletizer is easy to disassemble and assemble. Under the condition of meeting the mechanical function, it is necessary to design a head with rhythm in and out, tight joint, uniform heat transfer, convenient disassembly and assembly, and no material leakage.

 

The hob of Meissen glass fiber pelletizer is easy to disassemble and assemble. Under the condition of meeting the mechanical function, it is necessary to design a head with rhythm in and out, tight joint, uniform heat transfer, convenient disassembly and assembly, and no material leakage.

 

The hob of glass fiber pelletizer should be streamlined. In order to make the material extrude evenly along the runner of the machine head and avoid overheating decomposition of the material due to stagnation, it must not increase sharply in the machine head, and there must be no dead angle and stagnation zone. The runner should be lubricated as much as possible. It is recommended that the surface roughness Ra value is 0.4μm

 

The correct cross-sectional state of the glass fiber pelletizer hob is different from the actual cross-sectional state of the product due to the function, pressure, density, shrinkage and other factors of the plastic. This factor should be considered in the design to make the die have a proper cross-sectional state.

 

What is the mold of plastic profile products with continuous state of Meissen glass fiber pelletizer hob, also called extrusion mold, extrusion molding head or die head. The principle of Meissen glass fiber pelletizer hob extrusion (extrude) is composed of Latin "ex" (separate) and "trudere" (push), which generally describes the extrusion process of "applying pressure to drive the data through the mold. During the processing of the extrusion die, the polymer with powder or granular shape is usually withdrawn into the barrel of the shearing blade. Under the action of the screw or plunger, the polymer moves forward along the screw groove or barrel and gradually melts to become viscous fluid. Then it passes through the die set at the end of the barrel to form a continuation similar to the die state of the die. After that, it is cooled and shaped, it can be molded into products in the required state, such as various plastic pipe bars, sheets, plastic steel doors and windows, films, skirting lines for decoration, etc. The general design points of plastic extrusion molds are the peripheral parts of extrusion consumption. The technical form of extrusion molds is indirectly related to the stability of extrusion consumption, the quality of extruded products, the efficiency of extrusion consumption and the service life of the molds themselves. Therefore, the design of extrusion die is very important.

 

In the nose design, should pay attention to the following points:

 

Meisen glass fiber pelletizer hob material selection proper head to choose erosion resistance, friction resistance, good tensile strength, high hardness of steel. Some also according to the situation chrome.

 

The sufficient tightening ratio of the hob of the Meissen glass fiber pelletizer depends on the different plastic products and plastic varieties, and the design can produce sufficient tightening ratio of the head to eliminate the joint seam formed by the shunt bracket, so that the products are dense.
