Recently, the one-step flow coating PERT insulation pipe production line HSD315 developed by Qingdao Huashida Machinery Co., Ltd. has passed the appraisal of Shandong Equipment Manufacturing Industry Association, and the overall technology has reached the international advanced level.
This production line can form the inner tube, polyurethane foam layer and sheath layer in one go. Its flow-coated insulation and flow guiding mold can precisely control the thickness of the foam layer and is not limited by the material of the inner tube, solving the problem that the traditional "one-step method" process cannot detect the foam thickness in the production of PERT pipes. In addition, the production line achieves fully automatic production, which can reduce the number of operators by 1 to 2 compared with traditional processes.
On June 6th, China Chemical Industry News and the new media "Chemical Industry Number" reported on this, affirming Huashida's industry status and technological innovation achievements.
