“ZENITH” three roll builder machines are specially developed for making printing rollers from rubber sheet.

Three Roll Builder “ZENITH” three roll builder machines are specially developed for making printing rollers from rubber sheet.

After a long experiment of almost 18 months in collaboration with Rubber Technologists from Germany, we "ZENITH - INDIA" have developed a new Rubber Compound for Inking and Dampening Rollers for printing machines. This compound is being manufactured from German raw-material & we are launching this product after getting positive response from our Domestic & International customers who had tested the rollers made from this compound.   High Chemical and Solvent Resistance. Uniform wetting of the Printing Plate. Maintains the required hardness for a longer period of time. Resistance to shrinking, swelling & abrasion. Resistance to hardening even when exposed to isopropyl alcohol and substitutes. Facilitates more rapid attainment of the ink water balance. Excellent resilience , with grinding tolerance of less than 5 microns. Achieves fine film thickness on its surface and on plate, resulting optimum fountain Solution on plate ie. ultimately on pa per to reduce paper stretching. Quick and easy to clean.  

STRIP BUILDER ZENITH strip builder offers synchronized consistent rubber application for large or small rollers. Machines are designed for efficient performance. Designed with provision of cold feed and hot feed extruders with built-in electrical,pneumatic controls and other application equipments. Roller covering extruder plant complete with movable carriage holding the cylinder to be covered.

Hot feed screw type extruders are heavy-duty machines built to suit individual needs. They are made in many different type and sizes to meet the production requirements for straining extruding, tubing, slab production or contoured shapes. The extruder’s size depends upon the hourly output required and method of feeding with a complete line of equipment is available to meet with all customers need. The Cold feed Extruders have been developed for processing cold rubber compound. Since these machines in addition to extruding profiles also plasticize rubber; they differ from hot feed extruders, they have longer screws; heavier gears boxes and higher drive power. According to present stage of development cold feed extruders can be used for extruding almost all rubber compounds, which are process able on hot feed extruders. Feeding is normally in the form of strips or pellets. Machines with longer screw diameters are often fed directly with wig-wag stored slabs.

Features : BED The basic bed is heavily steel fabricated, machined to a single frame on which whole machine with gearbox and motor is fitted, DRIVE Worm is driven with belt and reduction gearbox arrangement etc.
