How To Do Temperature Control Work When Forming Uhmw Sheets

In general, the temperature during the molding of the uhmw sheets has a great influence on the product quality, and special attention needs to be paid to controlling the temperature in the middle of the mold slightly lower than the temperature at both ends. 


To have uniform and stable temperature conditions to assist, the distance between the die lip should be equal to or slightly less than the thickness of the plate. The uniform and stable temperature ensures that the flow rate of the extruded melt volume is stable and equal pressure, so that the longitudinal thickness error value of the liner is minimum. 


Molding mold temperature control to stabilize the temperature is too high or low to affect the flow rate of the melt, so that the thickness of the formed uhmw sheets will produce a larger error. At higher temperatures, the molten material is easily decomposed and there are bubbles in the liner; when the temperature is low, the surface of the liner is dark and not smooth.


The above content is our introduction to the temperature control work that needs to be done when the uhmw sheet is formed. I also hope that I can better help you through the above description.
