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
