When it comes to manufacturing industrial heated rollers, R2R Engineering sets itself apart from the competition. In fact, they specialize in manufacturing high-mix, low-volume rollers and rotating equipment. What's more, their product line is versatile and flexible, making them perfect for virtually any application. We have compiled some useful information for you in this article. Read on! Below you'll find more details about the advantages of R2R rollers.

Stabilization of Substrates

The R2R transfer setup consists of a hot roll lamination unit, an electrochemical delamination unit, and a rewind unit. The process begins by growing 2D material on a metal film, laminating the film between plastic substrates, and then electrochemically separating the two layers. The finished product is glued to a glass slide for further characterization.

The thermal and mechanical strains produced by the process are significant, and this is why it is essential to stabilize the substrate before transferring it. Thermal mismatches in the process of thermal pyrolysis cause substrates to stretch, and soften. Thermal mismatches create a third distinct gas zone that cools the substrate. The third gas mixture is injected upstream from the far end of the annular gap and issued out of the inner tube. The third gas mixture quickly combines with the hydrocarbon flow away from the substrate, resulting in a significant increase in surface area.

In addition to stabilizing the substrate, double-sided processed film substrates have improved high-frequency signal transmission and might prove a key to Industry 4.0. This new process could enable flexible electronic manufacturing at a fraction of the cost of standard PCB technology. The technology can also be applied to existing infrastructure. These processes are also a key part of Industry 4.0. The benefits of R2R are extensive.

Thermal Treatment of Substrates

An example of an application for R2R Engineering industrial heated rollers for the thermal treatment of substrates is the production of flexible fabricated parts. The exemplary application demonstrates a substrate thickness of 125 m and a width of 1270 mm. The substrate is heated from about 120 to 180deg C using a drum rotating in a first and second direction. As the substrate is heated, tension is applied to it in both directions.

The characterization of the rollers is done to determine their adequacy in applying pre-tensions. The results can be used to improve R2R applications. The web is then treated in a manner that increases its heat capacity. Moreover, the rollers are misaligned when being moved along the web. Misalignment can also reduce the maximum pre-tension. This can increase the risk of web buckling.

Coating Quality of R2R Rollers

Coating quality of R2R Engineering industrial heated rollers varies with distance between the coater lip and the web, ink viscosity, surface energy and coating method. Various research groups have investigated these aspects. The most important factor in coating quality is uniformity. The web material used to coat the roller should be a thin, nonbreakable, flexible plastic film, such as polyethylene terephthalate.

The coating quality of R2R Engineering industrial heated roller machines was evaluated by comparing the results obtained with other technologies. In the current study, a SOFC was coated with YSZ electrolyte. YSZ is commonly used as an electrolyte in solid oxide electrolyzer cells and batteries, but it is not available in all applications. The higher the temperature, the higher the number of coating defects it produces.

Idler rollers manufactured by R2R Engineering are available in both live-shaft and dead-shaft options. These industrial heated rollers are available in a variety of coating materials, including zinc and nickel. These rollers can be customized for specific applications. Their precision is unmatched, and they feature a hardened surface for excellent heat transfer and low-fouling properties. These rollers can be used in many industries, and are highly reliable and extremely durable.

Flexibility of Design

The versatility of R2R Engineering industrial heated rollers is enhanced by the New Way Air Turns, which drive temperature from both sides of the web simultaneously. These innovative rollers eliminate the need for tension bars and spreaders, allowing better control over the web between the rollers. The flexibility of the design also eliminates the need for a tension bar or spreader, allowing for more effective stretching patterns.

Several studies have evaluated the effect of temperature disturbances and web tension fluctuations in a dryer. However, only a few have examined the effects of thermal deformation at the inlet of the dryer on web defects. The thermal deformations caused by driven rollers can cause unevenness in the web, resulting in a sine-wave-shaped deformation in the transverse direction. The irregularity of the web's surface can also affect the coating section, where the coating layer may become nonuniform and unstable.
