	Blow molding - Wikipedia, the free encyclopedia
		Blow molding is a manufacturing process by which hollow plastic parts are formed.
		The injection blow molding machine is based on an extruder barrel and screw assembly which melts the polymer.
		After a cooling period the blow mold opens and the core rod is rotated to the ejection position.

		EP 705678A discloses a moulding apparatus and process in which a flow of air or other gas is provided between the outside of the parison and the wall of the mould cavity as the parison drops through the cavity.
		Blowing air directly onto the parison, especially before the parison is inside the mould cavity, may result in excessive or asymmetric forces on it, causing it to distort or not to fall straight.
		Preferably the distributor is an annular arrangement located at the entrance of the mould cavity, having a central aperture for passage of the parison, an opening for attachment to a supply of gas, and at least one opening facing into the mould cavity for egress of the gas around the outside of the parison.

	Blow Moulding (Site not responding. Last check: 2007-10-12)
		Blow moulding is the process that takes an extruded pipe of plastic and introduces air into it, once sealed at both ends.
		Blow moulded products have a constant thickness of polymer at every point of the shell, and can be large in size.
		Blow moulded plastics are invariably thermoplastics because thermosetting plastics assume their final shape through heat and so can not be moulded with this process.

	Tat Ming - The Injection Moulding of PET Preforms and Bottle Caps
		In extrusion blow moulding, the bottle neck is not smooth, and has to be scraped to remove the flashing.
		Whether an air conditioner or a mould sweat protector is used, the clamping unit of an injection moulding machine must be fully enclosed to reduce the loss of dry air.
		Injection moulding of bottle caps is distinctly different from that of preforms in that it is thin-wall moulding.

	AMI Subject: Blow Moulding
		Blow moulding is used to create hollow enclosed components and there are two basic types of technology: extrusion blow moulding and injection blow moulding.
		In extrusion blow moulding a parison or tube is produced by extrusion.
		A mandrel or blowing stick is placed in the first mould, and the thermoplastics material is then injected into the mould flowing around the mandrel to create a tube.

	Watlow Ltd- Blow Molding in the Plastics Processing Industry
		Blow moulding is the art and science of making the hollow plastic containers that are indispensable parts of everyday life.
		Common processing techniques such as extrusion, stretch blow, injection and co-extrusion are all utilized in forming these parts.
		Whether it is a diverse and complex part that requires high performance such as an elastically functional automotive component; or a high-volume hollow piece such as a single-serve PET water bottle, the front-end blow moulding process still requires an exacting thermal solution.

	How to Process Plastics
		Structural Foam is a term commonly used to describe thermoplastic injection moulding components made by the injection moulding process which have a cellular core.
		Rotational moulding differs from all other processing methods in that the heating, melting, shaping, and cooling stages all occur after the polymer is placed in the mould, and no external pressure is applied during forming.
		Post moulding joining of the parts provides a means of achieving an end solution.
