The success of a PET packaging unit depends on the quality of the moulding facilities provided by the manufacturer of the system. The ultimate utility of the bottle or jar is proven by the superior properties in the caps and closures. These should possess high standards in terms of being leakage and pilfer proof. This is ensured when the cap closure mould manufacturer is of repute.
Such a company should have top class infrastructure for design and development of wide range of perfect PET moulds for the caps and closures to suit various patterns of the moulded packing containers. The moulds need to possess optimum properties for high-speed, high cavitations, high-volume applications. The hot runners need to be balanced for consistency in cavity-to-cavity filling. This is vital since a hot runner undergoes melt channel sizing analysis where balance, shear rate and pressure drop are optimized.
