Blow-Moulding Or Thermoforming Of Plastics Or The Like
(AREA)
Abstract
A method of manufacturing plastic containers with webbings, at which a polymeric raw material in the form of pellets is fed to a hopper of blow molding machine, then from the hopper to an extruder, where it is heated and then supplied to a head, at the head outlet the polymer mass is passed between a mandrel and a die, a tubular blank is formed by extrusion in a free air, moulds are approached and closed for blowing followed by supply of compressed air and molding polymeric containers of required shape. On the surface of the mandrel or die matrix or both together special grooves are made that provide non-uniform thickness of the container wall forming webbings.
