Electropneumtaics and Hydraulics (I) Pvt Ltd Chakan, Pune, Maharashtra

Electropneumatics makes light duty tube bending and end forming machines for bending of copper and aluminium tubes and sections for the air conditioning, heating and cooling applications. Parts such as evaporator and condenser coils for air conditioners, chest coolers, deep freezers and refrigerators, stainless steel plates for heat exchangers, etc. can be formed on specially designed machines for these applications. They are highly productive machines engineered to fit the customer’s needs. Rigid, high-tonnage specialised hydraulic presses are available for stainless steel heat exchanger plate forming. Since material cost if a large percentage of the component cost, these presses are specially designed for fast operation and low rejection rates.

Though stamping is an age-old, well-established technology, the advantage Electropneumatics offers here is the latest developments in this technology through modern stamping presses and specialised forming machines. We can produce large parts and complicated draws such as roof panels, skin panels and other automotive sheet metal parts on these presses. Our stamping line of presses from 25T to 7000T with bed sizes up to 2500 (LR) x 1800 (FB) are used for mass production of stamped sheet parts. Further capacity can be added depending on need.

Servo Mechanical Presses of slide and cushion speeds and motion sequences make blanking, shallow drawing, trimming, coining, too tryout, transferprogressive die operations, etc. possible on the same press. The large, high-performance AC torque motors drive the eccentric gear arrangement replacing the flywheel, clutch and brake and offering dynamic control over forming operations and energy savings.

The need for quick and reliable diemould tryout is constantly increasing because of the increasing number of new models and smaller batch quantities that are being produced in the automotive industry. In addition, forming processes have become complex, especially with the newer difficult materials. Therefore, it has become necessary to break-in and prove dies (new and reconditioned) well in advance of production start to save expensive production time. Electropneumatics’ Die Spotting and Tryout Presses have all the features needed to accurately simulate the actual manufacturing process for die prove-out.
