The difference between PVC cold top extrusion and hot drawing extrusion, please detail

pvc cold top hard top extrusion processing is the production of PVC high calcium pipe, PVC high calcium rigid profile and other commonly used PVC extrusion production methods, PVC high calcium pipe cold top extrusion is also called the internal pressure extrusion method, directly in the head of the machine cooled and shaped, no need for shaping mold, the production speed is slow.

The production process is from the head of the mold out of the material directly into the sink dip or water spray cooling, so that the PVC material from the mold outlet quickly cool down cooling, to achieve the effect of cooling and shaping, using pvc cold top hard top extrusion method of processing the appearance of the product is brighter, glossy and good.

My company specializes in the production of pvc cold top hard top extrusion processing equipment and cold top die.

PVC hot-drawing extrusion is PVC material out of the head through the shaping mold cooling and shaping or soft PVC directly into the water cooling and shaping.
