Extrusion blow moulding diagram.
Blow moulding machine diagram.
The thermoplastic is a blow moulding materials which is contain the form of small pellets or granules.
Blow molding or moulding is a manufacturing process for forming and joining together hollow plastic parts.
A hollow mold then closes around the parison and cycles to the blow station.
Extrusion blow molding injection blow molding and injection stretch blow molding.
It is also used for forming glass bottles or other hollow shapes.
In general there are three main types of blow molding.
When at the blow station the parison within the mold is molded through utilizing air pressure while another parison is being extruded from the machine.
This lesson is titled the process and the equipment.
Blow molding machine is a one type fabrication of plastics it is used to manufacture of hollow object by inflating heated plastic tube to fill a mold or die and form for require shape.
This tube is referred to as a parison.
The feed acts as the melted plastic and it is to be passed through the extruder head section and forming it into a parison.
Blow molding is the process of inflating a hot hollow thermoplastic preform or parison inside a closed mold so its shape conforms to that of the mold cavit.
The overview of all the parts of moulding machine is shown in the above diagram under segment a.
The feed from the extruder is given as an input into the blow molding machine.
