We are engaged in manufacturing, exporting and supplying excellent quality corrugated pipe extrusion line in weifang, shandong, china. 250h corrugator (making pipes of id90-250mm) Innovative mould blocks cooling solution of model 250h corrugator from zhongyuntech brings a fast and high efficient cooling of mould blocks, substantially increasing the production efficiency of pe double wall corrugated pipes. Innovative design of both the corrugator frame and mould blocks moving structure. The all-new design of corrugator structure makes the left frame and the right frame which the mould blocks are mounted on be able to open and close freely. The mould blocks on different models of extrusion lines can be interchanged completely through adopting a highly standardized system solution! innovative clasp style rapid assembly technology of mould blocks can realize easy and fast assembly of mould blocks on their bearer plates. Based on the further optimized design for the structure and running mechanism of mould blocks, it makes the mould blocks running forward and backward bidirectional on the corrugator! it effectively overcome the structural defects that ordinary corrugator only allow the mould blocks run in one direction. In the field of pe/pp double wall corrugated pipe machinery, zhongyun group is the only enterprise in china that has manufactured all the three kinds of corrugators. We are the top manufacturer in asia in the field of double wall corrugated pipe machine.
