Blow Molding Design Guide by Regency Plastics
geminigroup.netBlow molding is an umbrella term for forming hollow plastic parts by inflating a molten plastic tube, or parison, until it fills a mold and forms the desired shape. Think of it like inflating a balloon inside of a water bottle. There are three main types of blow molding: Extrusion Blow Molding Stretch Blow Molding Injection Blow Molding
Introduction to Extrusion - Dynisco
www.dynisco.comThe products of extrusion include: • Feedstock for Other Plastics Processes: Extruders are widely used as compounders, or mixers. The output from an extruder compounder is granulated or chopped to form the feed for another process, such as, injection molding or extrusion • Plastic Film: This is usually used for packaging or sealed into bags

Extrusion Blow moulding: In extrusion blow molding (EBM), plastic is melted and extruded into a hollow tube (a parison). This parison is then captured by closing it into a cooled metal mold. Air is then blown into the parison, inflating

Design Guides for Plastics - Tangram
tangram.co.ukmanufactured product but for plastics it is absolutely vital. We have no instinct for plastics. Most of those we use today have been around for little more than two generations. Compare that with the thousands of years of experience we have with metals. And plastics are more varied, more complicated. For most designs in
