Corrugator: corrugator is adopted horizontal structure with chain type transmission, equipped with open water cooling system and vacuum forming system. It greatly increases the production speed. The belling on line function decreases investment cost and improves production efficiency. Mold block moving adopts synchronous upper and lower mechanical drive system and advanced self-lubrication system. It assures moving accuracy and pipe quality stability. Mold blocks: they are corrugated forming molds which are formed by special aluminum alloy material through precision casting. They have high precision and strength, and excellent heat dissipation. Cutting machine: high-strength alloy steel blade, rotary cutting, smooth pipe incision, dustless cutting. The tracking device makes the cutting location precision. Germany siemens professional plc programmed controlling system makes operation easy and sensitive. 230
