Printing Rollers

To match international quality standards, we excel in rotogravure engraving machine that forms fine pyramidal pits known as cells into the surface of a copper-plated gravure printing cylinder as it is rotated. The dimensions of each cell (each of which corresponds to the image density of one scanned dot from the original) control the amount of ink the cells will contain, which thus determines the density of the printed image. An engraving head carrying a diamond-tipped stylus serves as the cutting tool for cutting the cells into the printing cylinder surface. The engraving operation is carried out by the stylus vibrating in response to a cutting-depth modulated actuating signal at a frequency of several kHz.

Copper plating is used primarily for its high plating efficiency as an undercoat for other metals, primarily bright nickel. Copper will cover small defects, such as pits and polishing lines. It can also be plated to heavier thicknesses and then buffed to remove and cover other defects prior to nickel/chrome plating. For these reasons, copper plating is used for plating die cast parts (aluminum or zinc) for highly cosmetic applications, such as automotive and motorcycle parts.

Hard chrome platting rollers acts as a protetive barrier to the engraved area and provides smooth finishing to the cylinders.

Our embossing rollers and capsule dish are in producing textured effects to suit almost any application. They can be used for embossing on pvc leather, pu leather, pe sheets, pvc sheets, pp sheets, glass, wallpaper, flooring and tissue paper. Our embossing rollers and dish capsules are highly durable and can be customized as per the requirement of the customer.
