Film metalizers present a special set of challenges to roll cover manufacturers. Homogeneous surface finishes, high release properties and tight dimensional tolerances require compounding and manufacturing expertise.
Engineered compounds from Stowe Woodward address the needs of the film metalizer with a family of cover compounds that deliver good surface finishes absent of voids or occlusions and with the necessary release properties for smooth film processing.
High abrasion and temperature resistance ensure that the performance properties remain viable for the life of the cover.
Coating
A bone hard cover is used to achieve special surface features and to attain specified caliper.
The successful cover resists fracture, wear, and degradation due to heat.
Pull
The pull roll maintains an equal tension across the film surface prior to entrance into the treater section.
The roll must retain its contour and hardness because cover hardening reduces the coefficient of friction thus impacting performance. This position also requires a high degree of resistance to ozone degradation.
Vacuum Winder Roll
The vacuum winder roll maintains an equalized tension across the film surface prior to entrance into the treater section.
The roll must retain its contour and hardness under challenging conditions. Roll hardening reduces the coefficient of friction thus impacting performance.
