TRADE SHOW PREVIEW 83 PET planet Insider Vol. 17 No. 10/16 www.petpla.net mould technology that facilitates the fill- ing of very thin wall sections. X-Mould is intended to give designers the power to design a 500ml bottle preform weighing as little as 7.2g that presents no production issues - and which can be processed on existing equipment. A new shine on old moulds, with Xcore With Xcore, it intends to offer a new metalising service for existing injection mould cores that will provide a cost-effec- tive way of modifying preform dimensions, down-gauging containers, and advancing materials saving. Xcore will be an alter- native and lower-cost solution to core- change programs for preform light-weight- ing within the range of 0.2-0.5g, when an investment in a completely new set of cores is hard to justify. Sipa calculates that on, for example, a 96-cavity tool, metal- lising cores to cut wall thickness down from 2.0mm to 1.9mm, achieving a weight reduction from 11.0g down to 10.7g, would pay for itself 2.6 times more quickly than changing the cores. A new generation of hot halves Hot halves have been given a thor- ough revision in the latest generation - the third - of Sipa injection moulds for PET preforms. New technical fea- tures include the incorporation of Xflow technology to produce a considerable enhancement in flow throughout the mould, creating a better balance and reducing pressure drops. Xflow makes use of the very latest con- cepts in polymer fluid dynamics to allow Sipa engineers to develop new design solutions that take greater account of melt rheology and so arrive at flow balances in the mould that are almost impossible to reach with traditional calculation systems. Third generation nozzles have an improved temperature profile and reduced pressure drop. Ease of maintenance has been improved, since it is now easier to remove nozzle inserts and install new ones; in addition, the performance of the nozzle tip over its guaranteed five million cycle lifetime has been improved. The new hot halves are compatible with standard cold halves and equip- ment used in the PET preform production sector. They use the same mechanical and electrical interfaces and same hot runner thickness, providing extra flexibility in use. www.sipa.it ATTN DRIES GENTLY AT A CONSTANT DEW POINT LUXOR A 80-2400 Now with ATTN ATTN brings more security in your drying processes.
