Changshu smoothly da plastic products factory talk about how the processing of PVC plastic profile production?

PVC plastic profiles are widely used in water supply pipe, household pipe, electronic product packaging, medical equipment, food packaging, etc. , is a kind of more widely used plastic material, because the PVC material has no flammability, high strength, good resistance to climate change and the geometric stability of the popular, so is how the processing performance of PVC plastic profile so good? Let well da plastic products factory in changshu to introduce how the PVC plastic material is processed.



in the processing of PVC plastic profile when the melt temperature is a very important process parameters, if the improper parameters can lead to problems materials decomposition. The flow of the PVC particularly poor performance, the scope of its processing technology is very small. Especially big molecular weight of PVC material is more difficult to machining, so often used is small molecular weight of PVC material. PVC, shrinkage rate is low, general is 0. 2 - — 0. 6%.



don't usually need to dry processing of PVC plastic profile. Melting temperature kept at 185 & ndash; — Between 205 ℃ and mold temperature: 20 & ndash; — 50 ℃ can, at the same time, injection pressure can be big to 1500 bar the holding pressure, can be big to 1000 bar injection speed, to avoid material degradation, general use reasonably the injection speed.
