2020 Maintenance Partnership

I have been working with printing and packaging companies’ maintenance departments for 40 years. Our company’s policies and procedures continue transitioning to keep up with the ever-changing requirements, solutions, and challenges to get the job done.

Depending on the type of business industry you serve, there will be projects that have “The Murphy’s Law” trophy. Let’s face it, our communication process can get lost down the supply chain, and when something goes wrong everyone goes into PANIC mode.

Developing a partnership as part of your supply chain, we can identify potential modifications that improve the performance and in most cases reduce out-of-pocket expenses. In the case of the hardened slitter rollers shown, WE SAVE THE AVERAGE CUSTOMER 40% WHEN COMPARED TO OEM COSTS.

Keys to a Successful Maintenance Project:

  • Identify the details
  • Communicate with team decision-makers
  • Plan in advance with your supply chain and logistics
  • Confirm dates for delivery of your products
  • Provide progress updates to keep them inline for installation

Your supply chain is an extension of your team to meet or exceed your project goals. PARTNERSHIPS ARE EVERYTHING!

I would be happy to assist you with your next maintenance project www.mgf-services.com.

Understanding Harden Slitters, Anvil, and Score Rollers for Printing, Packaging, and Industrial Industries

I get lots of questions about Harden Slitters, Anvil, and Score Rollers from my clients and potential clients in the Printing, Packaging, and Industrial industries.

There are hundreds of designs for slitters, whether it’s pneumatic or mechanical for razor, score or shear slitting substrates such as: paper, film, foil, cloth, non-woven, or vinyl. I will generalize a little bit in this post, because it’s impossible to cover every type of design in detail.

During the lifetime of your equipment you will need to replace your harden rolls more than a few times depending on your operational hours and applications. People often ask me, “How do I get the best value and extended life on my replacement?”

One of the biggest keys to harden rolls’ longevity is the hardness scale and effective depth on the roller construction. The Rockwell hardness on the slitters must be at least 2-4 points less than the roller construction hardness. The average hardness scale that can be achieved through normal heat treating practices are 62 RC. MGF’s process for these types of rollers goes beyond the normal heat treating with adding “cryogenic treatment” providing a 64-68 RC.

Nylon Rollers

I’ve worked around “Rollers” for decades. I practically grew up around them. Rollers are such an important component of any press and lots of industrial manufacturing machinery. Rollers get used a lot in a variety of ways. Whether they’re pushing something through or slowing something down, there is a constant state of friction. Friction causes wear. And rollers can wear out quickly. But now, there are incredible coatings for rollers, that allow the rollers to wear at a much slower pace. Nylon rollers are so versatile…let me tell you a little more about the logic behind it:

Copper and Ebonite® rollers have traditionally been utilized as metering, transfer and oscillator rollers in ink trains in offset and letterpress.

Nylon (Rilsan-11 ®) has come into its own as a higher performance replacement for copper and Ebonite ®. It provides superior ink transfer and virtually eliminates stripping and expensive maintenance. Nylon (Rilsan-11 ®) is more chemical resistant, as well as more resistant to scratching and surface damage. The physical properties of nylon (Rilsan-11®) allow it to be finished to a variety of specifications such as polished, spiral grooved, micro-grooved, knurled, or diamond grooved. These different surface configurations will affect the performance of the roller in different ways and allow it to be used in different positions. Smooth nylon (Rilsan-11 ®) is excellent for use in the oscillator or vibrator position while knurled, spiral or diamond-grooved patterns are ideal for the metering position to regulate the laydown of ink. The amount of ink depends on the surface configuration chosen.

Basics of Draw Rollers in Paper Machinery

Draw rollers, also known as pull, traction, driven, all have one thing in common: Tungsten carbide (Wolfram) coating.

The primary function of draw rollers are to guide and draw paper. The coatings on the roller determine the “lifespan of the roller.” The life of the roller coating depends on the operational use, of course. Typically, however, this coating will last years. How do you know when it’s time to repair? When the roller starts to look “smooth” or takes on a glazing appearance, it is time to “recover” your roller.

In my experience most customers that we service don’t have spare or extended downtime to recover. What you need to have is a pre-planned repair which includes:

  • Verifying dimensions
  • Verifying tolerances
  • Knowing the base material of roller
  • Knowing the type of grit (fine, medium, or coarse)
  • How many times has your roller been recovered
  • Committing to confirmed dates the press will be down to expedite your roller recovering.

Depending on the size of your roller, recovering a roller can typically be completed (by an experienced shop) in 5 to 7 days.

Should you repair or replace your Printing Machinery Parts?

The printing industry is ever-changing, but your machines are always running. When things start to fail, how are you supposed to know if it’s better to repair or replace your machinery parts?

Unless a part has reached its threshold to repair, you should be able to refurbish most mechanical applications. Such as:

  • Ceramic rollers
  • Idler rollers used in handling adhesives, hot plastics, sticky material
  • Draw rollers
  • Stationary jaws
  • Former board and noses
  • Corona Treater rolls
  • Chrome rollers

These parts can be extremely costly to replace. I have been repairing these types of parts for decades. If you hire the right company, you can save a lot of money by expertly refurbishing worn parts.

However, there are certain mechanical parts where repair/refurbished are not viable options. In these cases, replacement parts are the only recommendation to ensure quality and performance. These parts may require replacement rather than repair:

  • Concave/reverse/crown bowtie- rolls
  • Lead Rolls
  • Anodized chill rolls
  • Hardened anvil/slitter rolls

Through our 30 plus years in the maintenance repair industry, our growth opportunities come from listening to customers and providing services and improved products. My company, MGF Services, has a track record of 30 to 40 percent cost savings over the OEM market value. Older machinery in operations are faced excessive OEM price and delivery or no support at all. MGF’s reverse-engineering and network of extra services provide customers a solution to keep their equipment running without extended downtime.

  • Size of part to be coated
  • Coating thickness
  • Operating environment

What are you trying to accomplish?

  • Wear resistance
