Qingdao Huashida Machinery Co., Ltd., through continuous technological innovation, has obtained multiple national patents in the field of insulated pipe equipment, effectively improving equipment performance, reducing labor and material costs, and bringing significant benefits to pipe manufacturers.
Addressing the issues of insufficient production efficiency and precision in large-diameter plastic pipes, Huashida has developed a new type of large-diameter plastic pipe extrusion die. This die is connected to the extruder outlet and achieves rapid and precise die adjustment through components such as a auger, die body, expansion sleeve, die, and adjusting screw, effectively reducing material leakage and improving the uniformity of pipe wall thickness. In its structure, the expansion sleeve and die adopt spherical contact and can be further fixed by a pressure plate to ensure stability and sealing during the adjustment process.
Based on feedback from domestic and international customers over ten consecutive years, Huashida's insulated pipe equipment demonstrates excellent performance in production speed, efficiency, and labor and material savings, and has become a recognized leading brand in the industry.
