One of the latest products is a full-plastic floor-mounted accelerator pedal.
“On the lightweighting front, we have been working on change of material from steel to aluminium to plastics as appropriate,” says ShailendraGoswami, CMD, Pushkaraj Group.
His next target is to offer plastic air inlet manifolds for CVs. Given the high stress factor in a CV engine, the challenge of increasing plastic content is more than cars. “Statistically, in the West, 50 percent of the inlet manifolds in cars are only in aluminium, 80 percent of fuel tanks are made of plastic," Goswami points out.
He shares a long list of plastic components ranging from air inlet manifold, rocker arm, battery case to fuel tank that he is sourcing, or in talks to source for Indian OEMs, from foreign suppliers.
Goswami, an engineer, who worked at Kirloskar Oil Engines before turning entrepreneur, points out that a plastic component is relatively easier to be used in a stationary engine, but it has to meet more stringent tests for application in commercial vehicle engines. It’s worth it since a plastic part “can cut weight by 60 percent compared to a traditional all-aluminium part”. He and his son, Pushkar (also an engineer) are scouting many markets to find such solutions. What next? “The futuristic applications for plastics will include parts like conrods and crank shafts followed by engine blocks”! That, perhaps, is too futuristic for India now.
