Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Thickness of hard chrome plating ranges from 2 to 250µm. Various types of hard chrome include micro-cracked chromium, micro-porous chromium, porous chromium and crack free chromium. It is essential that the micro-cracked and porous coatings have a minimum thickness between 80-120µm in order to confer adequate corrosion resistance. Micro-cracked chromium has a Vickers hardness of 800-1000 kgmm2, while crack-free chromium has Vickers hardness between 425-700 kgmm2. The formation of micro-porous chromium is achieved by a specialised plating method involving the use of inert suspended particles. Porous chrome plating is developed by etching electrodeposited chromium. These are designed to retain lubricant, for sliding and bearing type applications.

Vikram manufactures four types of high efficiency tea rollers - Single Action in two sizes - 36" & 46" Double Action in two sizes - 36" & 46" These Tea Rollers are efficiently engineered - fitted with heavy-duty bearings and robust body to take any amount of pressure. The Direct Drive mechanism ensures minimum power loss. The most important advantage is that standard components are used across the entire range of rollers, thus requiring just one set of spares.

As we came across the performance of standard nitrile rubber rolls for de-husking of paddy in rice mills, with our in depth knowledge of polymer composites, we soon realized that this cannot be the ultimate material for de-husking, considering the three parameters of life in tonnage, de-husking efficiency and the most important of all the broken percentage. Hence few years back we started our laboratory experiments with different formulations, though we shall always remain in the process of improvisation in terms of all the three parameters, as of now we are in a position to offer to the industry, rolls made of elastomeric polymer composites which can give multiple times life while maintaining optimum de-husking efficiency through out its life. Now our focus is on reduction of broken percentage and for that we need full co-operation of the industry has a whole. We promise our full devotion of this mission of developing
