- Feb 06, 2018 -

Blow molding machine can be divided into extrusion blow molding machine, injection blow molding machine and special structure blow molding machine three categories. Stretch blow molding machines belong to each of these categories. Extrusion blow molding machine is a combination of extruder and blow molding machine and clamping mechanism, which consists of extruder and preform die, inflation device, clamping mechanism, parison thickness control system and transmission mechanism. Parison die is to determine the quality of blow molded products, one of the important parts, usually side feed die and the central feed die. Large-scale products used in blow molding cylinder type parison die. The smallest cylinder storage capacity of 1kg, up to 240kg. Parison thickness control device used to control parison wall thickness, the control point up to 128 points, usually 20 to 30 points. Extrusion blow molding machine can produce volume range of 2.5ml ~ 104l hollow products.
