To accommodate different laboratory setups and sample loading requirements, our box furnaces are available in multiple door configurations. Choose the design that best fits your workflow and workspace.
Top-opening models are ideal for loading heavy or large samples from above using overhead cranes or hoists. Bottom-opening designs support specialized hanging fixtures and downward-loading workflows. Sliding-door variants minimize the footprint in space-constrained laboratories. All configurations support programmable multi-segment temperature control with PID or PLC controllers for repeatable calcination, ashing, and laboratory sintering processes.
Atmosphere Furnaces
Brother Furnace's atmosphere furnaces allow heat treatment and sintering under precisely controlled gas environments, including reducing atmosphere furnace operation with H₂ or forming gas, inert atmosphere furnace processing with Ar or N₂, and oxidizing atmosphere for controlled oxidation studies.
By eliminating unwanted chemical reactions, our controlled atmosphere furnaces enable reduction annealing, powder debinding, MLCC sintering, fuel cell component processing, and magnetic material annealing with consistent, reproducible results.
The hydrogen atmosphere furnace models include full safety systems — automatic gas purging, flame arresters, and leak detection — for safe H₂ operation in laboratory environments.
Tube Furnaces
Brother Furnace's tube furnaces provide a precise, uniform heating zone within a cylindrical work tube, making them ideal for CVD tube furnace applications, gas-solid reactions, chemical vapor deposition (CVD), PECVD processing, and small-sample heat treatment under controlled atmosphere.
Our range includes horizontal tube furnaces, vertical tube furnaces, rotary tube furnaces, split tube furnaces, fast-cooling tube furnaces, and multi-zone tube furnaces — covering the full spectrum of laboratory and pilot-scale thermal processing needs.
All models are compatible with quartz, alumina, and silicon carbide work tubes, and support atmosphere or vacuum operation.
Crucible Furnaces
Brother Furnace's laboratory crucible furnaces provide a simple, reliable, and cost-effective solution for non-ferrous metal melting, glass frit preparation, salt bath processing, and low-melting-point alloy melting in laboratory and small production settings.
The open-top design allows easy access for sampling, stirring, and pouring, making it the preferred choice for aluminum alloy melting, zinc alloy casting, and flux melting in metallurgical laboratories and educational institutions.

Frequently Asked Questions
Common questions from engineers, procurement managers, and researchers evaluating Brother Furnace equipment for their thermal processing applications.
A vacuum sintering furnace removes all gas from the chamber before and during the sintering cycle, achieving the highest level of contamination-free processing. This is ideal for reactive metals (titanium, tungsten), cemented carbides, and materials sensitive to trace oxygen or nitrogen. An atmosphere sintering furnace replaces air with a controlled gas (H₂, N₂, Ar) rather than pulling a vacuum — typically lower in capital cost and suitable for materials that benefit from a specific reactive or inert gas environment. Many applications can use either; our engineers can advise on the optimal choice for your material and process.
Yes — all Brother Furnace products support full customization. We regularly customize hot zone dimensions, maximum operating temperature, vacuum level, atmosphere gas compatibility, quenching media, loading configuration, and control system (PID, PLC, SCADA integration). Please share your process parameters and we will provide a tailored technical proposal within 24 hours.
Our vacuum furnaces cover a wide range depending on the model and pump configuration. Standard models achieve 10⁻³ Pa (medium vacuum) with a rotary vane pump, while high-performance models equipped with a diffusion pump or turbomolecular pump reach 10⁻⁴ to 10⁻⁵ Pa (high vacuum). Ultra-high vacuum configurations are available on request for specialized research applications requiring <10⁻⁵ Pa.
Standard laboratory furnaces (muffle furnaces, tube furnaces, crucible furnaces) typically ship within 2–4 weeks. Custom vacuum furnaces — including vacuum sintering, brazing, heat treatment, and VIM furnaces — generally require 6–12 weeks depending on specification complexity and current production schedule. We provide a firm delivery timeline with every confirmed order.
Yes. All furnace shipments include comprehensive operation manuals, wiring diagrams, and maintenance guides. For larger vacuum furnace systems, we offer remote video-guided installation support and online operator training. On-site commissioning and training services are available upon request for customers requiring in-person support.
Brother Furnace equipment is deployed across a wide range of industries including aerospace & defense (turbine blade heat treatment, superalloy sintering), automotive & EV (tool steel hardening, battery material synthesis), medical devices (titanium implant annealing, surgical tool brazing), electronics & semiconductors (MLCC sintering, magnetic material annealing), powder metallurgy & MIM, cemented carbide & cutting tools, and university & research laboratories worldwide. If you are unsure whether our equipment fits your application, contact our engineers for a free consultation.
Vacuum gas quenching uses high-pressure inert gas (N₂ or Ar) to cool the workpiece after heating. It produces bright, distortion-free parts with no residue and is ideal for complex-shaped components, high-speed steels, and mold steels. Vacuum oil quenching uses quench oil as the cooling medium, achieving faster cooling rates — necessary for materials like bearing steels and carburized parts that require a higher critical cooling rate to achieve full hardness. Our engineers can recommend the right quenching method based on your material grade and required hardness profile.
