TRADE SHOW PREVIEW PET planet Insider Vol. 20 No. 10/19 www.petpla.net 70 Zero Cooling, multiple benefits Nissei ASB Machine Co., Ltd., a leading manufacturer of machines and moulds for injection stretch blow moulding of PET and other plastics, intends to be making a strong impact with the target audience with live moulding demonstrations of five ASB-Series machines strongly showcasing ASB’s recently introduced “Zero Cooling” moulding process at its 712m 2 booth. The major sectors of the PET container market that utilise one-step injection stretch blow moulding (ISBM) process are commonly those where containers are designed for market appeal and brand quality. This is par- ticularly true for cosmetics, personal care, pharmaceutical, household or general food packaging. Zero Cool- ing - ASB’s advance in pre- form cooling technology - is claimed to suit the needs of these industries as it enables increased product quality at short moulding cycles. Taking full advantage of ASB’s propri- etary 4-station, 1-step moulding method, the required preform cooling is now shifted away from the injec- tion station and into the second, conditioning sta- tion to reduce injection cycle times. Crucially, the Zero Cool- ing moulding method, first announced in 2018, enables short cycle times while avoiding the need for thin, compromised design preforms that are suscep- tible to several quality related problems, most notably the undesirable ‘fisheye’, ‘body ring’ and ‘orange peel’. Now, with the preform designer able to freely focus on a shorter preform design with a thicker wall section that optimises stretch ratios, the result is improved quality as well as increased productiv- ity, states the company, and contin- ues: Actual results from typical Zero Cooling moulds have shown 15% or greater increase in stiffness and topload strength, improved control of material distribution and an average of 1.5 times productivity increases while improving on visual quality. In addition, since the container strength has now been improved by better orientation, more scope is available to apply additional light-weighting to the container’s specification. The advanced cooling method also enables the moulding of heavy- weight premium cosmetic contain- ers in dramatically shortened cycle times exhibiting no haziness even when using standard, lower cost PET grades, rather than the higher priced specialised, low-crystallisation grades that are normally required. All this is intended to result in visual qual- ity while saving cost and boosting productivity by 2-3 times over conven- tional moulding of these glass-like, premium designs. ASB-12M - small size with vast capability The model ASB-12M has estab- lished itself in the class of small, fully automated 1-step stretch blow mould- ing machines. Its Version 2 specifica- tion is intended to bring great perfor- mance and utility to the table. The Vision1 control system ensures that response & communication speed is 2.5 times faster than dedicated PLC systems enhancing machine cycle efficiency and control precision. The PC based system makes it flexible in use and compatible with Industry 4.0 for enhanced factory networking. Also, a larger, easy to read panel provides easier access to relevant information without changing pages. Other advan- tages include touchscreen opera- tion, improved operator feedback Hall 14 Nissei ASB Booth B38
