Hebei Yuxin Plastic, a leading PVC film manufacturing company saved more than $133,000* annually by switching to ExxonMobil’s gear and bearing oil, Mobil SHCTM 636. The introduction of the advanced lubricant in its PVC film calender machine helped to reduce component wear and quadrupled oil drain intervals.
The manufacturer, based in Xiongxian, North China, was suffering from increased downtime, due to frequent oil changes and bearing replacements. After an on-site investigation by an ExxonMobil field engineer, the cause was determined to be the operating temperature of the calender roll bearing, which exceeded 100°C, resulting in quick oil oxidation and bearing failure.
After switching to Mobil SHC 636, a lubricant renowned for excellent high temperature oxidation stability and anti-wear capability, the operator saw reduced maintenance and increased uptime. On a wider scale, it also reduced employee interaction with the machine, diminishing potential risk of injury.
“PVC manufacturing is both a thriving and challenging industry. Increased competition means every detail in a plant’s operation must be optimised,” said Rainer Lange, Mobil SHC Brand Advisor - EAME at ExxonMobil. “Our field engineers give customers a personalised service that can increase overall plant performance. In this case, the introduction of the right lubricant resulted in more uptime and annual savings of more than $133,000.”
