Pet Preform extrusion blow molding is a process in which plastic is melted and extruded into a hollow tube. Subsequently, the parison is captured by enclosing the parison in a cooled metal mold. The air is then blown into the parison to expand into the shape of a hollow container, bottle or any other component. When the plastic is properly cooled, the mold is opened and ejected from the part. The most common extrusion materials are acrylic, polyester, polycarbonate, PVC, polystyrene, polyethylene, and the like. The two variations of extrusion blow molding are continuous and intermittent. It is further divided into the following sub-categories: Continuous extrusion equipment Runner blow molding system Shuttle machine Intermittent extrusion machine Reciprocating spiral machine Accumulator head machinery Safety precautions for extrusion blow molding are: Make sure the machine and floor are free of oil It is necessary to keep the machine and floor free of particles Never cross or be protected by machine guards Do not try to climb between the tie rods while the hydraulic pump is running Remember to wear enough noise protection The fire extinguisher should be at 75 feet, so know the location of the portable fire extinguisher For safety reasons, be sure to wear suitable foot and eye protection It is recommended not to wear soft shoes All of these technological processes require a great deal of practical and theoretical knowledge to get the final product through mass production.
