Thanks to polymer scientist and engineers, the polyethylene terephthalate (PET) has ushered a new era in the packaging of both and non-edible products. However, the overall quality of packaging depends on the PET preform molds inserts, particularly the ones produced on the globally well known Husky brand systems. These are H-PET Injection Moulding machines.
Apart from the high grade steel usually imported from Japan or Sweden, the other yardsticks to ascertain the superior quality of a preform mould are –
- Low Preform eccentricity, not more than 0.1/0.2mm
- Low I.V. (Intrinsic Viscosity Loss) Loss
- Low weight variation between cavities, less than +/-0.2 gm
- Excellent Perpendicularity
- Low Preform temperature at exit to avoid scratches on Preform
- Smooth finish
- Flash free
- Accurate Thread Finish for better Closure Fitting
- Uniformity in Wall Thickness with high clarity
- Dust Free
- Almost Zero ‘AA’ level, suitable for beverages
As for manufacturers of top quality preform moulds Delhi NCR (national capital region) has some companies of international repute like the NOIDA-based Ashish Tools. This company has mastered the art of designing and developing moulds with such top precision that while blowing the preform the material is uniformly distributed and thus ensure superior sturdiness and improved transparency.
The preforms are made under rigid quality control conditions here while a fully equipped laboratory ensures that all products meet and even exceed beyond international standards. They are available in a variety of neck and weight categories.
A notable hallmark of this company’s products and services is its expertise in a perfectly balanced hot runner system that ensures uniform melt flow and pressure in all the cavities. Best sliding properties of all moving parts ensures minimal maintenance cost.
Although India’s share is less than five per cent share of the world’s $550 billion packaging industry’s share, the country is making great strides in this segment. For instance, the Indian Institute of Packaging has developed a new technology to pack tender coconut water with higher shelf life and qualities to retain its natural flavour.
