Using Plasma Coating To Improve Web Traction In Printing Applications

When it comes to serving the printing and packaging industry, delivering to market machinery that can maintain print quality, improve speed of production, and increase profitability is a sure-fire way to stay ahead of the competition as an OEM.

Paying careful attention to the web, how it is kept on the rollers and in contact with the printing componentry throughout the printing process, can really help control these variables, and adjusting the traction to suit the type of paper or plastic being printed can add real performance-driven precision to the machines you design and produce.

The rise of bespoke surface coatings

Customer demand, time pressures and factory automation are just some of the drivers shaping today’s manufacturing landscape. Machines are running faster, and for longer, than ever before, and for OEMs this means making adaptations to their machine designs in order to maintain optimal performance in increasingly hostile conditions – keeping quality of output high and waste levels low.

One such adaptation is the use of bespoke surface coatings, capable of enhancing the performance of a machine for its intended application. Whether that’s applying a carefully considered surface roughness to improve the traction of a product to the machine, colour coding a production line for factory efficiency or improving the longevity of equipment with improved abrasion resistance, bespoke surface coatings can withstand the increasingly harsh environments of modern manufacturing.

Plasma or polyurethane for abrasion resistance – what’s the difference?

Plasma coatings and polyurethane coatings are both popular, long established systems for protecting components against abrasion. Knowing which one is right for your facility can prevent costly coating failure, replacement and extensive machine downtime. 

Marcote’s surface coating specialists have an unrivalled knowledge of each coating system and many years’ experience specifying and applying the right coatings on an application-by-application basis. To help you make the informed choices, we caught up with Sam Woodcock, Managing Director of Marcote, to discover the difference between two often confused coatings – plasma and polyurethane:

From semiconductors and piping systems to centrifuges and agitators, applications that use chemical extraction, heating elements and treatment baths benefit from a chemical resistant coating to prevent the expensive and often catastrophic effects of corrosion.

An important part of many industries, chemical resistant coatings prolong asset life, prevent machine or component failure and maintain industrial uptime. Here, we look at the science behind chemical resistant coatings and explore a number of performance-driven coating systems.

If your system needs to be non-stick, to improve production line performance, improve hygiene and make clean down faster, selecting the right surface treatment can feel daunting. There are many things to consider, including which coating is right for the substrate you want to treat, operating temperatures, corrosion levels and load capacity. Here, we will explore how to make choosing the right non-stick coating as easy as possible.

For manufacturing applications, applying a non-stick coating to key machinery contact points such as conveyor belts, weigh pans, chutes and moulds can make clean down quicker, maintenance faster and hygiene better.
There are performance benefits to the right non-stick coating too, like improved production flow rate and product release to prevent bottle necks and reduce the need for human input in key areas of the process.

Here, we look at the science behind non-stick coatings, like Teflon/PTFE and Xylan.
