PET perform tools is the most modern and advanced tooling technique adapted in the fields of moulding house hold objects. For moulding the objects specific steels are used. This helps different objects to mould in different shapes and sizes. In plastic moulding the plastic is moulded in to certain shapes of various measures. A mould is used to control the shape of the object. The objects filled in the mould under pressure and cooled to obtain the specific shape. Actually a PET perform mould is a test tube of plastic using a plastic called PET. PET stands for the polymer called Polyethylene terephthalate. These type of polymers is lower heat resisters that can be easily transformed I to different shapes. The mould is actually using this polymer to mould certain shape for the plastic. The mould is available in different cavitation of different measures. The object filled in the mould gets the desired shape of the mould in which it is filled. PET bottle of plastic is such a moulding product using this type of moulds.
