Two kinds of shaping devices for PE pipe production line

According to the difference of raw materials and manufacturing rate, different quality demand can choose different shaping structure. At the present stage of PE plastic pipe production line more popular shaping equipment has two key kinds: cylindrical mouth mold sleeve and block combined mouth mold sleeve.  The effective selection of pipe fitting shaping equipment plays a great role in the quality of pipe fitting and the rationality of manufacturing.  

In the two kinds of shaping equipment, the cylindrical mouth mold sleeve is widely used, which has more widely applicable characteristics.  For cylindrical die sleeve, the stability and symmetry of water flowing through the inlet ring immediately harm the extrusion quality of PE plastic pipe production line, and the cooling speed of melted raw materials in the die sleeve can also harm the quality of pipe fittings.  

For the production and manufacture of PE pipe with small diameter and rapid extrusion, the extrusion rate of 35m/min or more can be achieved according to the diameter of pipe fittings and the production and processing of raw materials.  The block shaping equipment is composed of several layers of thin metal sheet, with a circular hole in the middle of the die, and fixed by the support column on both sides.  The space between each layer of thin metal sheet is standard throughout the guide direction of the embryo material.  The space increases slowly. When it is close to the guide end of the blank material, the space in the middle of the metal sheet is smaller to avoid hoarding and squeezing of the blank material still in the melting state in the middle of the sheet. With the generation of hard layer on the surface of the pipe fitting, the spacing in the middle of the metal sheet can be increased slowly.
