TEMPERING OF LEAF SPRINGS

An expansion of Pyromaitre's core market, the leaf spring market has presented several recent opportunities for conversion to lean tempering. In addition to the significant speed advantages, 40-minutes as compared to the conventional 120-minutes, these leaf spring machines deliver further operating cost advantages. The conventional ovens required a 3 million BTU burner system, while the high speed oven required only 1.5 million BTU for the same capacity. The reduced length of the oven enabled the use of air for cooling rather than the traditional use of water. The waste heat from the air cooling chamber is used to heat the building during the winter months, off setting monthly plant heating bills. The operators were also quite fond of clean dry parts and were able to throw away their rubber aprons and gloves.

Conventional: 120 minutes

Pyro: 45 minutes
