Injection moulding machines Check your hydraulic oil


Hydraulic oil expenditure represents a fraction of the cost of running injection moulding machinery. But a small change in hydraulic oil can result in big performance breakthroughs, such as prolonged component life, improvements in overall equipment efficiency and reduced cycle times.


Operating challenges: In injection moulding, hydraulic oil is generally exposed to compression, shear stresses and a wide temperature range. This can trigger the oil’s molecular breakdown, which reduces its lubricity and component protection. This means your equipment has to work harder, is less protected and may use more energy. High temperature operation can lead to oil oxidation, which can result in corrosion, a build-up of damaging lacquer and an increase in viscosity. Hydraulic oils can also become contaminated with process materials, water, dust and wear debris. This can trigger pump failures while increasing filtration costs.


Switch to advanced hydraulic oil: To combat all of these issues, it is important to use a hydraulic oil with excellent shear stability and a high viscosity index. High performance hydraulic oils maintain their optimum viscosity across a wide range of operating conditions, helping to protect equipment, improve energy efficiency and extend oil drain intervals. That, in turn, can help to reduce maintenance, cut costs and enhance operational safety by reducing employee interaction with machinery. Extending oil drain intervals can also cut waste lubricant disposal, improving a company’s overall environmental credentials.


Used oil analysis: Maintenance can be further reduced by the use of a used oil analysis programme, such as Mobil ServSM


Lubricant


Analysis. By analysing oil samples, it is possible to gain invaluable insights into how both the equipment and lubricant is performing. Issues can also be detected before they become a problem, helping maintain peak operational efficiency and productivity.

This Proof of Performance is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.


An energy saving guide for injection moulders 9 In the field


A manufacturer of plastic buckets, pails and drums


reduced its energy bill by 4.28%2


after switching to


Mobil DTE 10 Excel™ 68, a high performance hydraulic oil.


The ExxonMobil lubricant was trialled in one of the manufacturer’s Windsor Armour 150 tonne injection moulding


machines. The month-long test showed that Mobil DTE 10 Excel 68 enhanced the overall productivity of the machine, compared with the previous


lubricant, and improved its energy efficiency.
