Oil Program
Skip to the bottom to see some great before
and after photos of
what your system might look like if you don't keep your oil clean!
Oil Program Rates
Rate per test = $99 (+ Element) 
Over 3 machines = $79 (+ Element, less 5%) per test conducted by MRI staff

MRI oil test kits = $49 per kit.
Hydraulics & Pneumatics Magazine says studies show that contaminated oil causes over 75% of molding machine downtime. Abrasive wear from particles in the oil, which are slightly larger than the clearance spaces in the valves and pumps, is what destroys them. Many companies make a conscious effort to keep the hydraulic oil in their machines clean, yet few of them realize just how clean the oil should be.
SPI's Recommended Guidelines for Hydraulic System Filtration state "constant monitoring and maintenance of system fluids can improve machine operating performance more than any other single factor. Scheduled monitoring of the system filtration levels must be part of the standard maintenance program. Of equal importance is the degree of keeping accurate records of maintenance data. This allows for proper analysis of component failures and machine performance."
MRI provides complete oil analysis for your equipment on a 90 day cycle. The analysis offers viscosity trends, an ISO particle count bar graph and table, which track the analysis history of your machine, as well as, the ISO code ranges for injection molding machines.
We recommend Filtroil’s On-Line .01 micron bypass filtration system and cartridges. The system comes complete with a testing port for drawing samples and a gauge that indicates when to change filters. MRI can provide the filtration units you need and install them on your machines at our regular service rates. (Ask us about pricing and multiple unit discounts.) We can then implement our Oil Program by coming in quarterly, taking the oil sample, replacing the element, and sending you the analysis described above for your records. We take on all the work and simply bill you quarterly.
Sources of Contamination
Machine Manufacturing
Weld spall, sand-blast grit, and metal chips are produced as the machine is
manufactured and often lurk in a manifold block, reservoir or other parts of the
system.
New Oil
New oil does not come with any cleanliness guarantees nor are they part of
the oil specifications. When tested, new oil is consistently below acceptable
levels of contaminants.
Machine Operation
As soon as a new machine begins to operate, hydraulic components begin to
wear and generate additional contaminants. This continues throughout the
life of the machine.
Moisture and Foreign Particles
Contaminants are brought in through the air breathers as oil surges up and
down the reservoir introducing moisture and particles including plastic fines
and pellets into your system.
Exposure to the Atmosphere
Although the rod packing, seals and wipers retain the oil in the cylinder,
contaminants can enter the system as the rod extends and retracts during normal
machine operation.
Dirty Environment
Not all maintenance is done under the cleanest of conditions. Particles
over 5 microns can easily get into the hydraulic system when it is
open for repairs.
