All IMD pistons are made from the latest specification silicon aluminium alloy material.
This conforms to the required percentages of specialist metals, the most important of which is silicon. Silicon has been proved conclusively over a prolonged period, to give the best ring groove wear rates coupled with a low coefficient of low expansion rates. Strength has been achieved using a modern construction technique which has allowed the weight to be reduced in the piston. The weight of the piston is the most important factor in engine design, since the effect of reciprocating weight is transferred directly in terms of bearing loads, engine balance and maximum permissible speed. The lighter the pistons are, the lower are the loads placed on the crankshaft main bearings.
IMD have achieved piston weights comparable with the original parts, and will in the future improve upon this through innovative design.
This weight reduction is now common place in automotive piston manufacturing worldwide, our pistons conform to this industry practice without any compromise, is kept to the lowest level concomitant with adequate strength.
IMD Pistons can provide automotive vintage, classic motorcycle and modern vehicle piston assemblies. Please Let us know your specific requirements.
