Aventics’ clean line cylinder series

‘Energy Saving Guide’ for injection moulding ExxonMobil has launched its ‘Energy Saving Guide for Injection Moulding Companies’, in partnership with leading research consultancy, Applied Market Information. Developed by industry expert, Robin Kent, the free hand- book contains practical guidance and insights to help plastics processors cut their energy consumption. Theguideoffersbestpracticeadviceonalmost every aspect of an injectionmoulding plant, from howto create an ‘energyfingerprint’ tousing high performance hydraulic oils. The guide alsodetails likely savings that are available, including: • Fitting insulation to barrel heaters, which ac- count for up to 25% of the energy input of an injection-moulding machine, can cut heating costs by 50%. • Reducing compressed air leaks: reducing pressure drops and improving pipework can cut compressor energy consumption by 50%. • Switching to Mobil DTE 10 Excel™ hydraulic oil can help increase hydraulic efficiency by up to 6%. “Plastics processing is a highly competitive and energy-intensive industry where every detail matters,” saysMohamedMourad, industrial mar- keting advisor at ExxonMobil. “TheEnergy Saving Guide for Injection Moulding Companies covers every important detail tohelpplastics processors optimise their operationand cut power consump- tion. The practical, hands-on guidance can help operatorsmake a real impact on their bottom line and give them a competitive edge.”

With two newcylinder series to ISOstan- dards, Aventics has recently expanded its actuator product range for applications with high hygiene requirements. The pneumatics specialists now offer a solu- tion to meet strict requirements placed bythefoodandpharmaceuticalindustries. The new Aventics cylinders, available in SouthAfrica fromTectra Automation, comply with all relevant European standards for applications in food splash zones. Both the CCL-IS standard cylinder to ISO 15552 and the CCL-IC compact cylinder to ISO 21287 correspond to the basic principles of hygienic design: the cylinder bodies consist of anodised alu- minium, while the screws and piston rod are made of stainless steel. The scraper material and the lubricants are also FDA-approved. The CCL-IS standard cylinder is avail- able in eight sizes covering diameters from25 to 125mm. Themaximum stroke is 2 750 mm. Depending on their require- ments, users can choose between elastic and pneumatic cushioning. ST6 series proximity sensors canbe installed in just a fewsteps, without theneed for any special tools. The ST6 sensor series includes a wide range of versions with different line lengths and connections. Aspecial feature of the new cylinder series is the option to configure the air connections either on the cover or the base or both. Supply air and exhaust on one side increase flex- ibility for engineers, especially since the Mpumalanga Renovating Maintenance Services (MRMS), a leading cleaning and maintenance specialist servicing the lo- cal industrial cleaning, civil, and general construction sectors, has standardised on rental machines fromGoscor Cleaning Equipment (GCE) to ensure it receives the lowest total cost of ownership. When MRMS secured a three-year civil site-maintenance contract at Kusile power station in 2010, it purchased its first cleaning machine from GCE, part of the Goscor Group. Following a second cleaning contract at Arnot power station, MRMS decided to rent all its cleaning equipment on a long-term rental basis, GCE GMGreg Venter reveals. In August 2013, MRMS direc- tor FJ Steyn, discovered the Highpoint Vacuum HPVR 1000 cleaning truck showcased by GCE at Bauma, ideal for cleaning operations at power stations and

The unused air connections are sealedoff with locking screws. With nine sizes, the CLC-IC compact cylinder covers thewidest range available on themarket, withdiameters from16mm to 100 mm. This gives engineers a maxi- mum degree of freedom, since they can exert both lower and higher forces. The maximum stroke of the compact cylinder is 500mm, and ismeasured by a proximity sensor from the ST6 family tailored to the application. The CCL-IC can be mounted directly, without any additional fastening elements. With the Aventics Engineering Tools, users can configure Clean Line cyl- inders online. Tectra Automation, the pneumatic, electric and mechanical drive technology specialists of the Hytec Group, is the sole distributor of Aventics in southern Africa.

other industrial sites. As aresult,MRMSacquired its first vacuum truck. “Thewaythevacuum truck is put together is of a world-class stan- dard. Apart from the fact that I could not im- port a truck at the same price nor of the same quality, I would face an impossible lead time of 12 months,” Steyn explains. In addition, the Highpoint Vacuum

MRMS also secured a maintenance contract with GCE, which ensures more output from its cleaning machines in the long run, resulting in maximum availabil- ity and ultimately the lowest total cost of ownership.

HPVR 1000 is simple and easy to operate. MRMS o r d e r e d a n o t h e r t wo HPVR 1000 wet and dry vacuum trucks and received delivery of these vehicles during early 2016 for cleaning operations atMatla, Kusile, andArnot power stations and other industrial sites.
