Are you having trouble with cracks in the plating transferring onto the mirror-finished rolls for film molding? It can be improved with crack-free plating.
Hard chrome plating has excellent hardness with a hardness value of HV750 to 900, but it has the issue of cracks (fine fissures) in the coating, which means that no matter how much the surface is polished to a mirror finish, the cracks can transfer to the product. Our company has long had the technology for a non-crack chrome plating called "Cloamore." The hardness can reach up to HV1800 through heat treatment at temperatures between 200°C and 600°C, and due to being crack-free, it has excellent corrosion resistance. However, since the coating can only be applied as a thin film with a thickness of up to 5μ, it has not been applicable to mirror surface rolls until now. However, we have developed a "Super Mirror Crack-Free Roll" that solves these problems by forming a special two-layer structure. 【Features and Effects】 ■ Achieves a super mirror crack-free surface with a roughness of Ry0.05 or less. ■ Since Cloamore is on the outermost layer, it has a hardness of about HV1200, which is approximately 1.5 times that of hard chrome plating, making it less prone to scratches due to its excellent wear resistance. ■ Being crack-free enhances corrosion resistance and reduces resin accumulation on the roll surface. It is also expected to improve anti-fouling properties and non-contamination effects. *For more details, please feel free to contact us.

basic information
Do you have any of the following concerns? - The surface of the rolls for film molding is polished to a super mirror finish of Ry0.05 or less, but there is a problem with micro-cracks from hard chrome plating transferring, which is affecting quality. - Even minor scratches on the surface of the rolls for film molding can transfer to the product, so we want to minimize scratches as much as possible. If you are struggling with issues such as the enlargement of micro-cracks or the transfer of cracks due to the deterioration of plating in optical applications like film molding, please consider our super mirror crack-free rolls. Currently, we are in the prototype stage and are not yet able to accommodate large sizes; the processable size is approximately Φ300x800 (long face). *For more details, please refer to the related links or feel free to contact us. ★Notice★ We have launched 'Chrome Plating and Roll Navigation.' https://otec-kk.info/
