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

tangram.co.ukblow moulding and thermoforming Designers must design for process as well as purpose and material. In single-surface processes for example, there is only indirect control over the form of the second surface. Design must take this limitation into account. 2 Good design is important for any manufactured product but for plastics it is absolutely ...
