Diffusion Bonding Hot Press

Diffusion Bonding Vacuum Hot Press

This versatile Diffusion Bonding Hot Press is an integrated system capable of exerting a force up to 200 tons in vacuum or controlled environments at temperatures up to 2400°F on parts heated in an effective hot zone 8" wide x 12" high x 20" long.

Water cooled rams and a cold wall resistance furnace are loacted within the vacuum chamber. External press frame supports chamber, vacuum, and hydraulic pumping systems. Saturable-core reactor power supply with solid state linear power control provides low voltage power to heating elements. Platens up to 8" x 20" in a variety of materials are easily attached to the rams. With the platens removed and the rams withdrawn, the system may be used as a general purpose high-temperature vacuum furnace.

FEATURES

• Joins material by simultaneous application of heat and pressure.
• Bonding occurs in solid state eliminating need for melting materials or melting point metal filler.
• Can be used as a general purpose high-temperature vacuum furnace.

APPLICATIONS

Materials may be joined by the simultaneous application of heat and pressure for a prescribed time in a high vacuum or inert atmosphere. The bonding occurs in the solid state, thereby eliminating the need for melting the materials as in welding, or the introduction of a lower melting point metal filler, as in brazing. Distortion and localized stresses are minimized and inaccessible surfaces can be successfully joined. Varying section thicknesses may be bonded to achieve a non heat affected zone surrounding the junction. Due to the vacuum environment, atmosphere senstive material can be processed without encapsulation. High vacuum cleans the surfaces to be bonded and assures high integrity joints.
