VA CU R E MA ® – P ET e x t ru si on t ec hn ol og ie s Sacmi: increased productivity, lower energy and better quality Sacmi’s CCM48SB is an evolution from the company’s CCM48SA model and is capable of producing up to 1,600 caps per minute, with lower energy consumption than its predecessor. Cycle times and energy consumption have both been reduced. Sacmi says that this machine is suitable for light single-piece caps for water bottles with moulding diam- eters up to 33 mm, as well as for single and double piece caps for CSD (Carbonated Soft Drinks). Energy savings are delivered by its CCM (con- tinuous compressing moulding) technology, whose consumption is equal to 0.75 kWh/kg at its maximum production speed. The company says this is 25% less than the best values found for injection technology. The machine has a CVS 052 (CVS 3000) optical inspection system integrated on the CCM exit belt. The Sacmi stand also featured a number of other quality control inspection systems. The CHS 003 “stand-alone” visual inspection unit can control both plastic and aluminium screw caps. Its three-camera system, which can be increased to four, uses two vacuum belts. The two sides are controlled first by the internal cameras, followed by an external colour camera. Together, they provide data that “explodes” the cap and checks the surface condition point by point. It can inspect up to 120,000 pieces per hour. The four-camera CVS 360 is designed to provide total control of lateral wall cap development, including searches for burrs on the cap jumpers with injection-moulded safety bands. “Cavity Recognition” can identify and read the number of cavities moulded in the caps, using an illuminator and dedicated software that collates defect sta- tistics. The “Spark Tester” can identify invisible micro-holes or cracks by using ‘electric rigidity’ principles. The CHS range can either be integrated into the line or deployed for post-production batch checking. The Sacmi SBF range of rotary stretch blow moulding machines, with six to 24 blow moulding stations, can produce more than 64,000 500ml bph. www.sacmi.com Microgel RCP water chillers from Frigel North America NPE 2012 saw the intro- duction of a range of twelve new water chiller models by Frigel North America. The Microgel RCP line of self- contained, water-cooled chillers are single-zone units that have been designed to meet the special demands of PET, closure moulds, multi-cavity moulding and other applications that need refrigerated high pressure/high flow coolant. The Microgel RCPs are available in sizes rang- ing from 9.2 to 126.7t. They are equipped with shell-and-tube condensers and can operate with a Frigel Ecodry closed-loop clean water cooling system or a conventional, evaporative cooling tower system, with or without heat exchanger. When used with a closed-loop system, the RCP units can be equipped with a “free cooling” option, which automatically shuts down the compressor when the Ecodry or closed-loop cooling tower system can produce coolant at the chiller set point. This is claimed to help achieve significant electri- cal energy savings during cold weather operation, with fans providing coolant to the process rather than the refrigeration compressors. www.frigel.com
