Research and Development
Our company has always laid great importance to innovations and improvements in process raw materials, products and testing. The innovations are considered the need of the hour and some of the important development activities are detailed below.
Improvements in raw material
A continuous thought is given to improve the existing product by making use of latest suitable raw material. For example, earlier for the two wheeler stand standard mild steel grade of tube was used. We thought of using high strength micro-alloyed steel (HSLA) for this application. We could reduce the thickness of material to get the same strength of the component. This reduced the vehicle weight, cost and gave a better material to user.
Another example of similar weight saving is making use of high strength St 52 grade tube in place of solid bar for use as a anti roll bar( or a stabilizer bar) in a four wheeler . By making this development we are the exclusive source of steel tube for Anti roll bar for Indica.
Electric resistance heating
At Innoventive we have developed a novel heating method for heating for annealing of tubes .As such in resistance heating there is nothing new as it is being used since long time. But using the resistance of the tube itself for electrically heating it was a novel idea. And we have successfully used and implemented it. This novel tube annealing equipment is successfully working for last more than a year and is giving good consistent results. The advantages are clean heating efficient heating and >80% use of electricity for heating.
We have been using induction heating for annealing of tubes for some time .Recently we made use of induction heating for hardening of steel tubes .By making use of special alloy steel (15B27) we have been able to get Tensile strength of 140 KG /mm2 in tubes; developed for impact beam application .These steel tubes were exported for use in four wheelers as impact beams.
Same heat treatment, which we have developed is being used for developing Anti roll bar for a new four wheeler which is expected to be launched soon by a major auto group .This anti roll bar also employs another novel way of metal forming That is of progressive forward extrusion of tube to suit the end connections.
Presently we are also developing the tubular anti roll bar for a proposed Bajaj 4 Wheeler by making use of not only the improved steel grade but also by making use of innovative idea of multiple forward extrusion process for end connections .This beam is also induction hardened to the tensile strength in excess of 130 Kg /mm2.
