FORGED PISTONS

Piston manufacturing has been the result of continuous research and development of unique materials, engine and piston designs and technologies through time. The forged pistons manufacturing process begins from the raw materials to a skirt coating finished part. Racing conditions demand the strength that only forged pistons can offer the engine builder and vehicle manufacturer. When compared to cast pistons, forged pistons are by far tougher and proven to be extremely durable in abusive racing conditions of all types. The forgings are designed to stand up to the any abuse that high performance motorsport applications require without failing, typically before any other part of the engine breaks.

Cast pistons are often found to be on the brittle side and are absent from the grain structure found in forgings of any kind. It is cast pistons that will inevitably fail catastrophically when the inertia levels are exceeded. Forgings have tightly condensed grain that is aligned to the basic shape of the piston or in other forgings the shape of the part. This produces higher mechanical properties and a better resistance to stress and fatigue within an engines harsh environment thus maximizing performance.

Skirt shapes and profiles are very specific to each piston application. The shape of the pistons skirt is one of the most functional areas on the piston besides the piston rings and gudgeon pin. It is the skirts that provide stability and smooth operation the cylinder sleeves bores. The pistons stability within the bore is of paramount importance for a proper piston ring seal and which also reduces levels of friction. Some forging alloys expand more than casting alloys to produce the most power, least wear, and best seal at optimum running temperature. Some pistons manufacturers offer a skirt coating, which ultimately ads to the toughness of the piston working together to minimize friction and produce more horsepower, and provide improved wear resistance. This process allows the piston to be fitted to the bore with a finer tolerance of bore to piston clearance, allowing a better ring seal, without compromising the reliability of the engine. Design work is very detailed to insure the latest piston skirt profiles for minimal rock, tight clearances, and long skirt life.

Engineers specialize in building custom forged or cast pistons to your exact specifications. Light weight forgings and extra strength forgings, skirt coatings, offset pins, and a variety of other features are available from manufacturers. Custom pistons for drag racing, oval track, rally cars, modified saloon racing and moto-X amongst many other forms of racing and are able to manufacture just about any piston required.
