Vacuum brazing, sintering, annealing and tempering in one compact system. Built for laboratory R&D, trial production and small-batch processing.
Develop joining and thermal-processing cycles on a compact vacuum platform. The VTHB-334 combines a molybdenum-heated chamber with an integrated control layout for work that moves between process trials and small-batch production. For a production line centered on one treatment, compare the dedicated vacuum heat treatment furnace types by process, load and cooling requirements.
For precision assemblies and small brazing batches. Discuss base metals, filler alloy, joint design and fixture dimensions with our team.
Our vacuum brazing joint design guide explains how clearance, filler placement and fixture restraint affect the trial.
For sintering trials and small components with thermal cycles compatible with the 1300°C maximum temperature and molybdenum heating system.
Plan sintering density checks around the incoming material, sample position and final part requirements when comparing trial batches.
For annealing studies and small production loads. Match the cycle to the alloy, component geometry and required material condition.
For an annealing-focused production route, explore the Vacuum Annealing Furnace for a wider choice of load sizes, hot zones and cooling configurations.
For tempering cycles within your heat-treatment workflow. Specify the material, prior treatment and target properties for furnace selection.
For repeated post-quench cycles, compare the Vacuum Tempering Furnace by working temperature, batch mass, recovery time and cooling requirements.
A 30 kg compact furnace with molybdenum heating elements, ±5°C temperature uniformity and an ultimate vacuum of 8 × 10−4 Pa.

The front-opening chamber gives direct access to the loading supports. Molybdenum heating elements serve the furnace’s brazing, sintering and heat-treatment applications.
Hot-zone selection also depends on material chemistry, carbon sensitivity and the process atmosphere. Our graphite vs molybdenum hot-zone comparison explains these selection factors.
The operator panel brings the furnace HMI, temperature controller, overtemperature monitor and process recorder together at the front of the system.
The compact all-in-one arrangement supports straightforward setup for laboratory and trial-production environments.
When developing a cycle, distinguish the controller reading from the temperature reached by the parts. The thermal lag and soak-time guide explains how load mass, shielding and measurement position influence the hold-time decision.

It supports vacuum brazing, sintering, annealing and tempering for laboratory R&D, trial production and small-batch processing. Share your material and process cycle so our team can match the application to the furnace.
The VTHB-334 has a furnace size of 300 × 300 × 400 mm and a load capacity of 30 kg. Other dimensions are available.
The furnace uses molybdenum (Mo) heating elements. Maximum temperature is 1300°C, with temperature uniformity of ±5°C.
The VTHB-334 suits small batches within its 30 kg capacity and 1300°C maximum temperature. If sintering becomes the main production process, or the load and temperature requirements move beyond this model, compare the Multipurpose Vacuum Sintering Furnace. It offers larger batch configurations and alternative hot-zone options selected for the material and thermal cycle.
Send your process, material, target temperature, component and fixture dimensions, batch weight, available utilities and installation location. Drawings and your planned thermal cycle help us prepare a suitable proposal.
Include your material, thermal cycle, component size and batch weight in your inquiry. Our team will help you define the furnace for your project.
