The usual method for making plastic bottles and other hollow items.
A method of fabrication in which a warm plastic parison (hollow tube) is placed between the two halves of a mold (cavity) and forced to assume the shape of that mold cavity by the use of air pressure.
A process in which a warm plastic parison or preform (hollow tube) is placed between the two halves of a mold (cavity) and is blown into the desired shape. This improves the gas barrier, stiffness, clarity and impact strength of the container compared to extrusion molding processes; and as a result, containers can be reduced in weight.
A method of fabrication in which warm plastic is placed inside between the two halves of a mold (cavity) and forced to assume the shape of that mold cavity by the use of air pressure. Examples of blow-molded containers are bottles and tight-head plastic pails and drums.
A plastics-forming process that uses compressed air to shape the final product by expanding it to fit the mold.
The process of extruding a hollow tube, called a parison, downward between two halves of a mold. As the mold closes, the bottom of the parison is pinched off and air is injected into the top forcing the material outwards to the walls of the mold.
The plastics fabrication process in which a parison is forced to form the shape of a cavity by applying internal air pressure.
A method of fabrication in which a warm plastic parison (hollow tube) is placed between the two halves of a mold (cavity) and, by using air pressure, the parison is forced to assume the shape of the cavity. The air pressure is introduced through the inside of the parison. The air pressure forces the plastic against the surface of the mold that defines the shape of the container.
An extruded tube (parison) of heated thermoplastic is placed between two halves of an open split mold and expanded against the sides of the closed mold by air pressure. The mold is opened and the part is ejected.
See 'Blow Moulding'
Blow-molding is a method of forming plastic whereby a hollow tube is made from molten plastic material and entrapped in a mold. Air is blown into the mold, expanding the tube and forcing it against the sides of the mold, thus forming into the shape of the part.
A method of fabrication in which a parison (hollow tube) is forced into the shape of the mold cavity by internal air pressure.
(extended definition) Process of forming hollow articles by expanding a hot plastic element called a parison against the internal surfaces of a mold. It is the usual method for making plastic bottles, wide-mouth containers, petrol tanks, etc.
Blow molding or blow moulding (see spelling differences) is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding; Extrusion Blow Molding, Injection Blow Molding, and Stretch Blow Molding.
