CASE STUDY

ML6 Polyurethane Significantly Improves Productivity and Reduce Downtime

Challenge

The world’s largest manufacturer of manila envelopes and folders, contacted Meridian Laboratories due to numerous challenges they faced with multiple rollers on various models of machines. Aside from the fact that factory supplied machine ground rubber rollers wore out quickly, the rollers caused numerous problems throughout the manufacturing process because of the very fact they were machine ground.  That’s where Polyurethane, ML6 comes in.

  • Inconsistent tolerances of the outside diameter caused paper jams
  • Poor friction on rollers as dust particles imbedded into the roller’s porous ground surface caused jams and misfeeds
  • Irregularities in rollers caused printing processes to shift or trail, which in turn produced flawed printing results and incorrect cutting actions
  • Flat spots on rollers caused jams and errors

These issues led to downtime and decreased productivity.

Within their fabrication processes, the manufacturer operated a variety of machines utilizing various sized wheels and rollers. Traditionally they operated their equipment until the parts failed. Although the metal core/insert on the parts remained usable, they were forced to purchase completely new parts – their current supplier providing no other option. Their supplier, the original equipment manufacturer, is located overseas which meant:

  • High priced replacement parts
  • Long lead times
  • Exorbitant shipping costs

Solution

After having purchased entirely new rollers for over 20 years directly from the original equipment manufacturer, they turned to Meridian Laboratory. To increase productivity and reduce downtime, the manufacturer needed a local, reliable supplier that could supply parts on demand as well as resurface their existing parts with new materials.

  • Meridian Laboratory’s precision molded polyurethane ML6 rollers fulfilled these requirements
  • Precision molding guarantees the exact surface finish, quality, and specifications on every single part. The diameters on precision molded Polyurethane ML6 rollers are guaranteed to be within +/-0.001” tolerance and T.I.R.
  • Since Polyurethane ML6 rollers are precision molded versus ground, the particles that eventually adhere to its surface can be easily removed, providing extended wear (longevity) and improved friction
  • Improved friction drive surface and higher tolerance parts decreases jams and machine errors

Meridian Laboratory can strip and recover parts in as little as a few days, depending on volumes. Additionally, all their products are manufactured in the United States and shipped worldwide; therefore, Thanks to Meridian Laboratory, they now have a set of spare parts in-house to install when spent rollers require refurbishment. This means decreased costs, minimum downtime and maximum uptime/productivity.

Since providing the initial samples, Meridian Laboratory now supplies different sizes and styles of parts in varying diameters and durometers based on their client’s applications and processes. This customer continues to turn to the expertise of Meridian Laboratory as they design new prototypes and create additional processes.

    I have work with Meridian Labs for many years. I started a new job and needed to have some pulleys covered with urethane … More for a very important piece of equipment. Vance came through and got the pulleys done in a few days. We machined a V-Groove in the urethane and got our equipment in full operation. I could not have done it with out their help. Best quality, fair pricing and a company you can count on.

    We ordered some custom urethane rollers to use as encoder wheels. They have gone way beyond our expectations to make sure … More our parts were correct and meeting our needs. Meridian Laboratory makes quality products and are extremely knowledgeable. They are a trusted resource for us.

    I ordered a drive roller for my high precision telescope tracking mount. A fantastic product that works perfectly. Vance … More was really helpful getting the product out to me. Great service and highly recommended.
