Rubber Rollers

• RUBBER ROLLERS (OFFSET PRINTING MACHINE)


• INKING ROLLERS


• DAMPENING ROLLERS


• PRESS READY ROLLERS


• RILSAN ROLLERS


• Rubber rollers take advantage of the desirable properties of elastomers such as impact strength, shock absorption, compression and deflection, abrasion and chemical resistance, high coefficient of friction, and controllable degree of hardness. These properties make them suitable for handling manufactured goods without causing damage to the item or to itself, in comparison with metal rollers. Plus, the rubber covering can be regrouped or repaired to continue its service life, in most cases, in less time and investment than a metal core repair. They are the preferred machine parts for applications requiring high surface durability with low to medium hardness. Rubber rollers, with proper design and engineering of the rubber compound, can withstand degrading forces brought by mechanical and thermal factors, chemical and environmental factors.

Anilox Rollers

• The Anilox Roller is often referred to as the heart of the flexographic press. It is designed to deliver a precise and consistent amount of ink to the printing plate. ARC focuses on giving its customer a precise and durable roller.


• Funcationality: : A flexographic inking system is sometimes known as an anilox system. The purpose of the anilox roller is to pick up ink from the fountain roller (or, in some configurations, directly from the ink fountain) and deliver a predetermined, metered, uniform amount of ink to the rubber printing plate.


• Available with plated finishes. Engineering, boring, welding, lathe cutting, balancing, copper plating and finishing services offered. Dairy, food processing, mining, packaging, and converting, pulp and paper and printing industries served.


• A volume of 8.0 BCM is engraved within a range of 165 to 300 cells per inch. Higher line counts are better suited to lower cell volumes. A 2.0 BCM volume for process or combination printing is engraved between 700 and 1,200 cells per inch

Rotogravour Pressure Rubber Rollers

• Rotogravure (or gravure for short) is a type of intaglio printing process, which involves engraving the image onto an image carrier. In gravure printing, the image is engraved onto a cylinder because, like offset printing and flexography, it uses a rotary printing press.
  Once a staple of newspaper photo features, the rotogravure process is still used for commercial printing of magazines, postcards, and corrugated (cardboard) and other product packaging.


• Best of Features for Rotogravure:Because gravure is capable of transferring more ink to the paper than most other printing processes, it is noted for its remarkable density range (light to shadow) and hence is a process of choice for fine art and photography reproduction, though not typically as clean an image as that of offset lithography. A shortcoming of gravure is that all images, including type and "solids," are printed as dots, and unless the ink and substrate combination is set up to allow solid areas to flow together, the screen pattern of these dots can be visible to the naked eye.


• Benefits:packaging manufacturing, it does have the ability to print on thin film such as polyester, OPP, nylon, and PE, which come in a wide range of thicknesses, commonly 10 to 30 micrometers.

Plastic Extruders Rollers

• Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.


• This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted by the mechanical energy generated by turning screws and by heaters arranged along the barrel. The molten polymer is then forced into a die, which shapes the polymer into a shape that hardens during cooling.

Silicon Rollers & Wheels

• Silicon rubber is used in lamination of any product in high heat more than 200 degree celcius.


• SILICON ROLLERS ARE ALSO USED IN HOTMELT COATING (HOTMELT IS ONE TYPE OF WAX COATING). Hot melt compounds are generally applied by processing tufted carpet over two applicator rollers. These application rollers have another set of rollers above them, called press rollers, to control the contact pressure of the carpet to the application roller, and a doctor bar on the roller itself, to control the amount of hot melt picked up by the roller as it comes out of the hot melt. Both applicator rollers are positioned in containers or reservoirs of hot melt.


• SILICON RUBBER HAS NON-STICKING & HEAT RESISTANCE PROPERTIES.

Damping Rollers

The final set of dampening rollers are the form rollers, of which most presses contain two. These rollers contact the plate before the inking form rollers and desensitize the non-image areas of the plate before the application of ink. Web presses utilize other configurations of dampening rollers

Decrease processing time.

Standardize run conditions.

Develop tests to determine roller endurance.
