Heat Treating

Laserage has been heat treating ceramic material for hybrid microelectronics in high-temperature kilns for over 30 years. Today our heat treating capabilities include salt-pot furnaces, small box ovens, small vacuum furnaces and kilns for heat-treating a variety of materials from nickel-titanium alloys, stainless steels and alumina ceramics to polymers. Furnace atmospheres can range from air to hard vacuum with the option of adding partial-pressure quenching using argon or nitrogen.

Salt-Pot Furnaces

We presently have five salt-pot furnaces which are designed to heat treat small metal parts in a molten salt bath. The advantage of heat treating in molten salt is primarily the very rapid heat-transfer rate coupled with the ability to closely control temperature.

The useful working space is 8 inches diameter x 12 inches deep. Small parts are typically batch annealed together on fixtures and can be water quenched to effect a very rapid cooling rate. These furnaces are often used for shape-setting of Nitinol components.

Please consult our product engineering staff to learn more about Forming/Shape Setting of Nitinol components.

Laboratory Ovens

We have a number of small laboratory ovens with heated workspace ranging in size from 4 x 4 x 4 inches up to 23.6 x 19.6 x 29.5 inches. Typically these ovens are operated in air from ambient plus 10°C to 260°C. The oven illustrated to the right is operated with a horizontal air flow which allows for tighter temperature uniformity.

These ovens can be used for forming and shape setting polymer components, stress-relieving welded components, shape setting Nitinol and heat-treating titanium parts.

Vacuum Furnaces

Laserage has the ability to fully anneal small stainless steel and cobalt chromium components in a vacuum atmosphere. The useful working space inside the vacuum chamber is 8 inches diameter x 12 inches deep. Typically these furnaces are operated from 500°C to 1300°C. The advantage of annealing in vacuum is the ability to avoid oxidation.

In addition to annealing in a hard vacuum, partial pressure annealing in argon or nitrogen can also be achieved. Please consult our product engineering staff to learn more about vacuum annealing of metal components.

High Temp Kilns

Laserage has been heat treating ceramic substrates for hybrid microelectronics in high-temperature kilns for over 30 years.
Typically these kilns are operated from 500°C to 1425°C in air. The useful working space inside the kilns is 15 x 15 x 15 inches.
