Metlab Potero

Description

Metlab was founded in 1928 as a manufacturer of aircraft components. As part of the manufacturing process, Metlab created an in-house heat-treating facility to handle delicate, lightweight weldments. The company developed and patented the first "drop bottom" or "gantry" furnace, to allow long, slender tubes and weldments to be hung in the furnace to minimize distortion. This furnace design revolutionized the heat-treating of aluminum as well as aircraft landing gear - providing minimum distortion and rapid cooling.

In January, 2001, Metlab purchased J. V. Potero, Inc., which was founded in 1956. The company specializes in protective atmosphere heat-treating of small to medium sized batches, induction hardening, and black oxide finishing of steel parts.

Customers either issue us purchase orders, or we provide them with a pad that they can keep in the shipping and receiving department for their use to write up individual orders for heat treating and surface finishing.

Metlab recently undertook a project with a major crane manufacturer to flame harden the bridge crane wheels for a large overhead multiple bridge crane system. The crane is installed at an aircraft manufacturer and is used to lift airplanes as they are being assembled. Over 1,500 wheels approximately 6 1/2? O.D. x 2 1/2? wide, made from 1045 steel were hardened. The requirement was a hard and uniform outside rim hardened to 425 BHN (HRC 45) and a case depth of 1/8?, minimum.
