Humpback Furnace manufactured by United Enterprises is a specialised continuous belt furnace featuring an inclined entry and exit (forming a hump-shaped profile) used for brazing, sintering and atmosphere heat treatment of small components.
Brief Description:
The humpback profile creates a natural barrier that traps lighter reducing gases (such as hydrogen or cracked ammonia) inside the heating zone, dramatically improving atmosphere stability and gas economy. This makes the design ideal for brazing of copper, brass and precious metal parts, as well as sintering of specialty alloys.
The furnace is offered in both electrically heated and gas-fired versions. Mesh belt conveyance, tight temperature control and in-house atmosphere generation make it a reliable, cost-effective option for atmosphere-sensitive processes.
Applications include copper-brazed assemblies, electronic components, hardware and jewellery components.

FAQs:
Q: Why a humpback design and not a flat belt furnace?
A: The humpback contains lighter reducing gases like hydrogen more efficiently, lowering atmosphere consumption and improving safety.
Q: What gas is typically used for brazing?
A: Cracked ammonia is most common; pure hydrogen or N2-H2 mixtures are used for high-end brazing of stainless and copper assemblies.
Q: Do you offer the furnace with quench section?
A: Yes. The exit can include a slow-cooling section, fast-cooling muffle or water/oil quench depending on the process.
