Caps and Closures in PET Packaging

admin Cap Mould manufacture in india , , 0 Comment

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.

Growth Signs for PET Industry in India and World

admin PET Preform Design , , , 0 Comment

By and large, the growth prospects for plastic processing industry in India for the period 2014-2015 that the Central Institute of Plastic Engineering and Technology (CIPET) had projected have been achieved. Segment-wise, this forecast had predicted installation of additional 40,800 units of processing machinery:

  • Injection Moulding     –           26,700
  • Blow moulding           –           3,900
  • Extrusion                     –           10,200
  • Total                            –           40,800

Simultaneously, the demand for preform moulds too would have increased manifold. No wonder, delegates at the Conference of PLAST INDIA 2015 held at Gandhinagar in Gujarat in early February this year focussed on technological upgradation in the industry. Thus they discussed advanced materials and Applications for engineering and high temperature applications, technological innovations and emerging new opportunities in the field of packaging.

Secrets of Attractive Bottles for Beverages

admin PET Preform Molds Inserts , , 0 Comment

With the onset of summer, almost all of us would relish drinking chilled water or an aerated drink which these days come in attractive plastic bottles and not so much in glass bottles of yore. Interestingly, at the outset there were apprehensions over the base material used in these bottles and also other containers being hazardous to the environment. However, scientists in due course clarified and confirmed that such products are eco-friendly. Well, these are actually made from a material known as PET, acronym polyethylene terephthalate and the technology its applications has literally revolutionised the concept of packaging.

The technique in the making of these PET bottles is through moulding done through extrusion process. And their quality depends on the PET preform molds inserts used to mould the bottles. These moulds come in a wide range in tune with the needs of the bottling plant. They are products of high precision engineering and made from high quality steel, mostly imported from Japan. Read more
