Jul 26, 2017

Blow molding machine can be divided into extrusion blow molding machine, injection blow molding machine and special structure blow molding machine three main categories. The tensile blow moulding machine belongs to each of the above categories. Extrusion Blow molding machine is a combination of extruder and blow molding machine and clamping mechanism, which is composed of extruder and Parison die Head, Blow expansion device, clamping mechanism, parison thickness control system and transmission mechanism. Parison Die is one of the most important parts to determine the quality of blow moulding products, usually with side feed type die head and central feeding die head. Large-scale products using storage cylinder type mold head. The storage tank has a minimum volume of 1kg, the maximum is up to 240kg. The Parison thickness control device is used to control the wall thickness of parison, and the control point reaches up to 128 points, generally $number point. Extrusion blow molding machine can produce volume range of 2.5ml~104l Hollow Products.
