Fully Automatic PET Stretch Blow Moulding Machines. The new P-E-T Active machines are fully operational. Each blow molding machine produces product by a double stage production process. The first step is pre-form production with the use of injection machine section. The final form (bottle) is made during the stretch blow molding process. Its efficient and reliable and ensures we can meet even tight production schedules.
Polyethylene terephthalate or PET was first manufactured in 1941, but only became commercially viable in the 70s. a new era of plastic bottle and container manufacturing had arrived.
At P-E-T Active products we start the process with pellets of PET which are loaded into an injection moulding machine which moulds the pre-forms. Using our own moulds we have the ability to currently produce up to 30000 pre-forms a day. Please see our latest projects page for more info on future technology plans for 2010.
The Pre-forms are loaded into a heating oven and then transferred into an air blowing machine. A mandrel is then into the pre-form and air is blown into it under high pressure. This forces the walls of the pre-form against the steel mould which forms the final shape.
The containers are quality inspected and transferred into stock or to the packaging department for dispatch.
