Extrusion blow mold

Features on extrusion blow molds: 1, Single cavity to 12 cavities. 2, volume from 0.1L to 120L. 3, Blow mold size capacity up to diameter 50 cm 4, made by mold steel S136 or aluminum 7075-T6 and QC-7, Beryllium-copper alloys are the most common mold materials due to it’s good thermal conductivity with good durability. 5, high production capacity, long life time. Features & Application Extrusion Blow mold Extrusion blow mold is the mold for extrusion blow molding, extrusion blow molding only works on special machinery: Blow molding machine. as you know, we are professional manufacturer of extrusion blow molding machine. we also made this extrusion blow mold for our extrusion blow molding machine. Extrusion Blow Molding Extrusion Blow Molding is one of several blow molding methods to produce plastic bottles, jars, and jugs. It is a common blow molding technology used to process many different plastics, including HDPE, PVC, PC, PP, and PETG – and very common with bottles requiring multi-layer technologies (bottles with special oxygen / moisture barrier requirements to improve product compatibility & stability). Steps of EBM process Extrusion Blow Molding is the simplest type of blow molding. A hot tube of plastic material, called a parison, is dropped from an extruder and captured in a water cooled mold. Once the molds are closed, air is injected through the top or the neck of the container; just as if one were blowing up a balloon. When the hot plastic material is blown up and touches the walls of the mold the material “freezes” and the container
