SPVC material is the largest usage amount and the most widely used material in medical tube industry, such as PVC infusion tube, dialysis tube, gas intubation, oxygen mask pipe that we are familiar with etc. The first set of SPVC medical tube extrusion production line of KINGSWEL MACHINERY BAODIE Company can be traced back to the 1990s, until now it has nearly 20 years research and development accumulation as well as debugging experience of medical SPVC polyester extrusion technology. We constantly improve the SPVC precision medical tube extrusion process (screw structure, die structure, vacuum forming method and control accuracy, as well as the precision of hauling speed), make the stability of the molding speed and size of the pipe accuracy control get continued higher. Now the third generation "SXG-T" series high-speed SPVC medical pipe extrusion line can achieve stable production with astonishing speed of 180 m/minutes, under the condition of meeting tube size volatility (CPK value≥1.67). In view of the widespread workshop length limitation problem in medical cleaning room, we have developed the second-stage tank with "synchronous coiling cooling", it can realize super cooling effect in short tank, and tube’s precision is out of affection. This can help clients realize capacity multiple increased without changing the existing plant.
