Product Introduction
Barrel heaters have very little impact on melting, an aspect of polymer processing that is misunderstood by quite a few. The main purposes of the heaters are to melt the polymer that remains in the barrel at cold startup, to assist in forming the initial melt, and to “trim” the barrel temperatures for specific purposes such as improving feed rate. However, don’t be mistaken, it is absolutely essential for extruders to process thermoplastic resins. Without the heaters, both twin screw and single screw extruders will be jammed very easily and very quickly.
The cast in heating allows liquid cooling as well, which we use circulating water. The fast heating that our heaters promote minimises the pre-heating time for the extruder. In the meantime, water cooling enables fast cooling process as well. The fast cooling and heating ability gives our extruder with fast response and accurate temperature control.

B.What are the advantages using under/in water pelletizing method?
Firstly, under/in water pelletizing method is necessary for materials that are too soft to be cut by other methods. When the material formulation is just too soft, using other pelletizing methods, such as water strand, air cooling hot-face or water ring hot-face, the granules will just constantly stick to the cutting knives, which the shape and size of the granules will be inconsistent and the production rate will be very low. Secondly, the shape of the granules pelletized under/in water are always in beautiful round shape due to the water flow, comparing to the rectangle shapes from other pelletizing methods. Thirdly, under/in water pelletizing twin screw extruder production line is highly automated comparing to other methods, where labour cost for operating the production line is much lower.China Spare Parts
