3 Corrugated packaging machines benefit from proper lubrication management
stability in order to ensure effective protection. There is also the possibility of glue spillage and fibre build-up along with the presence of metal particles if guide plates, slitter blades or rollers are not properly aligned. Choosing lubricants that continue to provide protection in the presence of contaminants is therefore essential to help maintain the peak performance of corrugating machines.
Are there any end-use factors that corrugators should consider when selecting their lubricants? A large percentage of corrugated card output will be intended for use as transit packaging for food. It is therefore essential that food- grade oils and greases are used that don’t compromise on overall performance. That’s why ExxonMobil has
developed Mobil SHC 462 PF, an NSF H1 registered food grade synthetic grease suitable for use in corrugators. It offers excellent high temperature performance up to 240 deg C and good wear protection, making it suitable for use in heated rollers. The Mobil SHC 462 PF is also suitable for Kosher, Pave and Halal food preparation offering processing engineers maximum flexibility during operations.
Will one lubricant be suitable for all parts of a corrugator? A typical corrugating machine will require a range of lubricants such as hydraulic oils, and grease for roller bearings. Different parts of the machine pose different lubrication challenges. Corrugators should therefore discuss each specific application with their
Identifying lubrication issues on a corrugated packaging line with a thermal ‘gun’
lubricants supplier or maintenance partner in order to ensure that all the parts of their production line are receiving the benefits available from appropriate high performance oils and greases.
How can lubricant selection help corrugators reduce their environmental impact? Effectively lubricating a corrugating machine can help reduce its overall power consumption, which not only reduces energy bills, but also positively impacts on an operator’s carbon footprint. In addition, high performance oils can offer extended drain intervals, which cuts the impact of waste oil disposal, while also reducing disposal costs. Improving environmental impacts can also help corrugators save money - even more reason to select high performance lubricants.
Will a high performance lubricant help a corrugator improve operational efficiencies? A properly lubricated corrugator can be more efficient than one using less effective oils or greases and this can be reflected in its
energy usage. Through outstanding traction properties, Mobil SHC Cibus Series lubricants have demonstrated the potential to provide significant energy savings: 3.6 per cent in gear applications* and 3.5 per cent in hydraulic applications.** There are health and safety
considerations, too. A well lubricated corrugating machine can be less prone to mechanical outages, which reduces the instances of unplanned maintenance and human-machine interactions. The fewer the interactions the less chance there is of an incident.
How do corrugators ensure that their material suppliers use high performance lubricants? Paper recyclers will be aware of the benefits of using high performance lubricants as recommended by original equipment manufacturers (OEMs). Some may also be working with their maintenance partners and lubricant suppliers to maximise the benefits available from choosing the most appropriate oils and greases.
