CASE STUDY

ML6 Polyurethane Matte Finish Rollers Drive Thin Rolls of Plastic Films

Challenge

Polyurethane rollers were being used in the packaging industry to drive thin rolls of plastic films. In this case, the thinnest plastic films were found to cling to the surface of any roller, rather than release while being driven as desired. This application demanded a high coefficient of friction with low ‘tackiness’. The customer tried multiple different rollers, also cleaning rollers with MEK and with soap & water, none of which helped enough to solve this issue.

(Competitor roller with ‘tackiness’ problem unable to deliver the high coefficient of friction needed, leading to a solution that only ML6 precision polyurethane could provide.)


Solution

Meridian Laboratory leaned on our engineering expertise and high-performance testing to specifically develop ML6 polyurethane matte finish rollers (still unground and featuring ML6 industry-leading tolerances). The end solution is one which provides the same tolerances and durability which Meridian Laboratory ML6 precision polyurethane is known for, but now features a non-stick surface for passing materials.

(Top two ML6 rollers feature the new matte finish, compared to the bottom two standard smooth high friction ML6 rollers.)


Product Details

Standard ML6 Precision Polyurethane products feature an unground, cast to size, surface finish – allowing for the maximum amount of contact surface between roller surface and material being driven. This smooth, unbroken surface is similar in concept to a racing slick tire on a drag race, providing maximum friction. ML6 also features increased longevity over typical ground rollers, because the outer skin of Meridian Laboratory rollers are left intact. There are applications, like this one, where the perfectly smooth finish is not optimum.

After rigorous testing and prototyping, Meridian Laboratory found that a different surface finish would be required to drive the material successfully, without increasing the hardness of the durometer. This called for a precise Matte Finish. The outer surface of the ML6 rollers was cast to be rougher than our standard rollers to allow for less friction, and to increase the release properties between the rollers and the driven material. All of this was achieved without changing the hardness of the polyurethane. This rougher finish uses the same precision casting process as all other ML6 products, the surface of the parts are not ground or machined in any way. This provides for the same long-lasting service life of the part, with a surface that is ideal to the application.


Constant Improvement

Meridian Laboratory has embraced challenges since 1963, and we always look forward to providing all of our great customers with the best possible solutions. Matte finishes can be made available for all durometers and in the majority of sizes that we produce.

    I contacted Meridian Laboratory to obtain a slip ring for my Undergraduate Senior Capstone project. The project required … More a slip ring capable of highspeed data transfer with very little noise to drive an LED bar on a fan to generate images. Sven Krause was very knowledgeable and responsive and helped me figure out what product I needed. He even managed to get the slip ring donated to our team and had great advice on how to integrate it into our project. The project was a huge success thanks to Meridian Laboratory.

    I found Meridian's polyurethane ML6 fit and finish to be superior to other rollers we had sourced in the past. The tolerances … More were very tight and eliminated a lot of the jamming issues we were experiencing from the OEM's parts.

    I searched for a proper rotary ground and never found anything that was high quality, priced right and reasonably sized until … More I found Meridian Laboratory. Adam from technical sales guided me through options and quickly zeroed into a solution that was perfect for us.
    Communications were great for payment and shipping and the unit arrived as promised.
    What I received it, it was like a jewel. High quality, perfect size and installed in minutes. The ground works flawlessly at any rotation.
    I highly recommend Meridian Laboratory. We were able to install the rotary ground and simply forget it. It works that well.
