CASE 1: Chain guide for “puller block” in conjunction with extruder
| MICROPOLY: |
1” x 2” x 12” chain lube block |
| CONDITIONS: |
Frictional heat on expensive profiled UHMW chain guide caused softening of guide and replacement of 40 blocks, 2 or 3 times per year. |
| RESULTS: |
Customer cuts MicroPoly blocks into 6” lengths and machines sides down to provide two raised shoulders. MicroPoly has doubled the life of the UHMW. Change out on the guides had cost customer $500 per block. 40 blocks x 2 changes per year saved $20,000. |
CASE 2: Chain conveyor carrying 8,000-16,000 lb. pallets – furniture manufacturer
| MICROPOLY: |
1” x 2” x 18” conveyor chain lubrication block is used to lubricate #80 chain, 50 ft. long with a 24 ft. center distance between 8” sprockets |
| CONDITIONS: |
Chain was lubricated every month with molybdenum disulphide grease, which left marks on the wood boards as they moved along on the line. The excess grease dripped, creating safety hazards and housekeeping problems and contaminating the wood. The chain became noisy in about 6 weeks if not lubricated. Chain speed was 1 revolution every 2 minutes. |
| RESULTS: |
The MicroPoly lubrication blocks have been in use for 6 years without replacement. The blocks are mounted between two plates with spring pressure applied. MicroPoly has eliminated the problems they were having with contamination, housekeeping, noise, and safety. |
CASE 3: Automation for car body carrier
| MICROPOLY: |
MicroPoly Sprocket for #60 chain |
| CONDITIONS: |
Automation was designed without chain lubrication, causing problems with chain wear and unacceptable chain life. |
| RESULTS: |
Installed July 1999 and still running. |
CASE 4: Sheet metal processing automation
| MICROPOLY: |
MicroPoly Sprocket for double #40 chain |
| CONDITIONS: |
Conveyor chain was periodically manually lubricated with an oil sprayer. This caused the oil to drip, thus creating the need to contain the excess oil in pans. Because of the severe safety hazard, the steel pans had to be cleaned out before the equipment and the chain could be serviced. |
| RESULTS: |
MicroPoly Sprockets have eliminated the safety hazard and increased the chain life. |
CASE 5: Re-bar and angle iron, open conveyor, return guide
| MICROPOLY: |
1” x 2” x 12” chain lube block |
| CONDITIONS: |
Some radiant heat, less than 200 degrees. Previous chain guide material did not hold up and had to be replaced 3 or 4 times per year. |
| RESULTS: |
MicroPoly chain lube blocks, placed at interval spacing, reduced replacement frequency of chain guide to once per year. This resulted in saving significant material replacement and labor costs. |
CASE 6: Parts conveyor chain drive – automotive manufacturer
| MICROPOLY: |
1” x 2” x 20’ conveyor chain lubrication block |
| CONDITIONS: |
UHMW guide material supporting the chain wore out prematurely. This resulted in inconsistent parts feeding problems. The chain would disengage from sprockets when worn down, leading to frequent guide replacement. |
| RESULTS: |
With MicroPoly, inconsistent parts feeding problems and frequent guide replacement were eliminated. After 3 years of use, the blocks are still functioning. |
CASE 7: Sludge lift chain – waste treatment facility
| MICROPOLY: |
1” x 2” x 8” conveyor chain lubrication block |
| CONDITIONS: |
Water and dirt get into pins. Chain life is very short. Application is indoors with no heat. |
| RESULTS: |
Results are very good. All conveyor chains are now lubricated in this manner. |
CASE 8: Conveyor chain lubrication – automation builder
| MICROPOLY: |
1” x 2” x 12” conveyor chain lubrication block
|
| CONDITIONS: |
Either no lubrication was used, with a short chain life experienced, or manual greasing was required. The alternative was an expensive automatic lubrication system that tended to drip, creating housekeeping and safety problems. |
| RESULTS: |
Housekeeping and safety problems were eliminated with no manual greasing requirements. |
