Currently, almost all the large, medium and small industries engaged in the production of processed food including beverages, syrups, liquor and spirits, edible oils, filtered mineral water, cosmetics, shampoos, pharmaceuticals, industrial lubricants, pesticides and insecticides etc. pack their merchandise using technology of PET molding. The light weight durable and recyclable PET bottles and jars have replaced the fragile glass as the base of packing this wide range of items.
Thus there has been a consistent nationwide demand for the products and services of mold suppliers. However, the preform molds must possess qualities of high and optimum applications. The base metal for the molds should be steel of international standards, mostly of German, Swedish or Japanese make.
The designer and manufacturer of the molds should have an acknowledged expertise in developing modular concepts for standard interchangeable mold components as well as facilities for proper refurbishments. To cite an example, there are products of a company named Acme Disys markets can boast of. As for preform molds, it offers highly optimized PET preform mold solutions to all it’s customers across the globe resulting in weight saving, reduced cycle times and faster returns on investment.
In the system conceptualised by this company, a well-balanced cooling channel layout and turbulent water flow, results in very consistent cooling and efficient heat transfer away from the preforms. Above all, it has mastered the art of internationally advanced two- step dual taper locating technology. Each cavity self- locks independently to ensure high concentricity of product.
The demand for preform molds is directly driven by the consumption of PET bottles. As an industry, it has been growing at 19.2% CAGR (compounded annual growth rate). Over the long term, the demand is expected to be buoyed by:
- The improving economics of PET, through raw materials cost reduction and production efficiency and scale, making pricing comparable to glass bottles
- The favourable LCA (life cycle assessment) of one-way PET versus glass
- The growing emphasis on and commercial benefits of pack weight reduction
