Every day we receive raw materials, both through tanks with a capacity of about 30 tons of PET or in BIG BAGS containers, and these are stocked in specific silos after the quality controls.
An automatic system placed on each moulding isle (press-robot-drying system) conveys the polymer (PET) into a 8-ton hopper. The material is left drying for about 5-6 hours at a temperature of 170 – 190C°.
We gather the material with a loading tube and activate the heating process through electric resistances, until the melting point (280/300°C). The melted material is then injected into a mould where it is cooled off by water circulating at 10°C, then we open the mould; the robot collects the preforms and place them onto a belt that conveys them to the packing boxes.
We label the box with the finished products and the operator will then stock it in a specific area of the warehouse.
