The heyu vertical vacuum furnace arranges the hot zone along a vertical axis inside a cylindrical chamber, with the workload raised or lowered through a bottom- or top-loading mechanism. The cylindrical barrel distributes radiative heating evenly around long, slender parts, and the vertical loading path keeps shafts, bars, and rings hanging straight so that gravity-induced sag is minimized during high-temperature holds. The vertical hot zones offered in this platform measure Ø600×800 mm and Ø800×1200 mm, reach 2400°C, hold temperature uniformity at ±3 to ±7.5°C, and pull an ultimate vacuum of 2×10⁻⁴ Pa with a pressure rise rate of ≤0.67 Pa/h. Because the door sits at the bottom rather than the side, the vertical footprint leaves the top of the chamber free for pump stacks and gas-quench manifolds.
We engineer the vertical load path around long and rotationally symmetric parts that would deflect on a horizontal hearth, and the bottom-loading design keeps fixturing simple for shaft-type production. Custom builds are drawn to your workload envelope, and the production cycle for customized equipment is typically about 60 days from drawing confirmation. For long precision shafts and rings, that straight vertical payoff means less post-heat-treatment straightening, tighter concentricity, and less finish stock left on parts that would otherwise exit a horizontal hearth with a measurable bow after cooling.

Application Fields
Long shafts, bars, and rods
Vertical hanging eliminates gravity sag during high-temperature sintering or solution treatment, which is the main distortion mode for long precision shafts.
Ring and cylindrical parts
The cylindrical hot zone surrounds ring-shaped workpieces symmetrically, giving uniform circumferential heating that a rectangular horizontal chamber cannot match.
Heat-loaded bell jar processing
The vertical barrel layout suits bell-jar style vacuum cycles where the workload is raised into the hot zone on a lift, reducing floor-space demand compared with a long horizontal chamber.
Customization
Cylindrical diameter and height, bottom- vs top-loading, lifting stroke, maximum temperature, heater material, and gas-quench pressure are configured to your parts. We build to customer drawings or prototypes.
Packaging & Transportation
We support EXW and FOB. The heyu vertical vacuum furnace is packed according to international export requirements based on the nature of the actual goods.
