1. The PE pipe production line adopts DC/AC motor, and Eurotherm DC/AC digital converter and high efficiency screw to ensure high efficiency extrusion. 2. This PE pipe machine adapts basket type composite die head, which ensures not only the uniformity of high speed extrusion but also the stable performance of tubular goods. 3. This PE pipe making machine adopts high efficiency double chamber vacuum calibrating technology and spray cooling bath to improve the rate of finished products of tubular goods and meet the demand of high-speed production. The vacuum bath and cooling bath adopt stainless steel. 4. This PE pipe production line adopts multi-caterpillar haul-off and ensures the synchronization. 5. The cutting machine adopts special saw blade with low noise, equipped with chip collector. 6. The whole pipe line adopts PLC control system and large liquid crystal screen, which makes the operation very convenient.
