11 common faults and solutions for PVC, PP, PE extruders Before introducing the common faults of the extruder, let's first understand what is a plastic extruder? Plastic extruders are divided into twin-screw extruders and single-screw extruders, as well as multi-screw extruders and screwless extruders that are not commonly seen. Extrusion systems include screws, barrels, hoppers, heads, and
Common Problems and Solutions in the Granulation of Five Modified Plastic Particles 1. Break 1. The raw materials have miscellaneous materials. Check whether the materials in the material opening contain miscellaneous materials. 2. Poor plasticization, the processing temperature needs to be increased. (For glass fiber reinforced composite materials, it is often caused by exces
Common problems and solutions of plastic granulator Common problems and solutions to plastic granulators: when the plastic granulator unit is in use, the friction clutch is disengaged, the unit is interlocked, and the price of the polypropylene granulator is caused by the frequent occurrence of such failures: the main motor The main motor torque of the system is too high or too low; the frictio
The five common problems of PVC cable material extrusion are quickly collected and very practical! PVC (polyvinyl chloride) mainly plays the role of insulation and exterior decoration in the cable. The extrusion effect of PVC cable material directly affects the use effect of the cable and also affects the customer's desire to buy. The following Tianjin PVC cable material manufacturers list five c
The solution of pimples on PVC extrudate When pvc granulation, you will find small particles on the products extruded from PVC, sometimes there are no acne, but no reason can be found. The following is technical assistance in formulation and process. 1. Pay attention to the number of resin crystal points. Regular manufacturers produce less "fish eyes", which is one of the main reasons.
7 common pelleting problems and solutions for plastic granulation Starting from the two processes of wire pelletizing and underwater pelletizing, we will analyze the 7 common pelleting problems and corresponding solutions for you, and provide some suggestions for your pelletizing production line to continue to produce high-quality products in large quantities. 01 Continuum problem Cont
1. The length of the strip is greater than 2 times of the normal pellets are considered as strips. The main causes are pull-on or broken bars, the direction of the bar is not straight, the bar is not suitable for immersion in water, the cutter of the pelletizer is worn or notched, etc. Main solutions: 1) During normal production, adjust the direction of the strip into the pelletizer and adjust
Problems and solutions that are easy to occur in the extrusion granulation of plastic granulator Hot-cutting granulation method is prone to problems during extrusion granulation. For other extrusion granulation methods, mainly the cooling method of the pellets is different, the factors affecting the quality of the particles are the same, let's take a look together below. 1. The pellets
