BOMO METALS · DRAWING-BASED MANUFACTURING

Vacuum Furnace Hot Zones & Components

Custom vacuum furnace hot zones and replacement components, manufactured to your drawing or developed from measured equipment and existing parts. BOMO Metals supports dimensional survey, design review and replacement planning for older furnace hot zones, from an individual component to an agreed assembly scope.

PRODUCT FAMILY 07

Choose the assembly or replacement scope

Explore five separate product and service pages. Complete assemblies, shield packs and heating-band layouts are reviewed as systems; material-specific components remain available through the related product links.

Three ways to start your project

Manufacture to drawing

Send the approved drawing, revision, material requirements and acceptance criteria. Identify complete assemblies, subassemblies and individual spare parts separately.

Survey and design review

Where drawings are incomplete, use measurements, equipment records and existing parts to develop the required geometry. Survey method, access and drawing approval are agreed for the project.

Replace an older hot zone

Record the present condition, interfaces to retain and intended duty. Compare an agreed rebuild scope with a new replacement assembly before committing to manufacture.

WORKSHOP WALKTHROUGH

See the hot-zone assembly and internal layout

This short workshop video shows a cylindrical assembly from the exterior into the internal component layout. Use it as a manufacturing reference when discussing access, component arrangement and the replacement scope.

For your own furnace, send a current drawing or measured sketch and photographs of the interfaces. The assembly shown does not establish a universal material grade, temperature rating or standard size.

Match the hot zone to the actual furnace

Discuss the work-zone dimensions, process atmosphere and vacuum requirements, thermal cycle, heating-system duty and loading arrangement. Metal grades and layer configurations are selected for the approved design; a photograph alone cannot establish operating suitability.

Vacuum heat treatment

Describe the alloy being processed, load arrangement, temperature cycle and required cleanliness. Mark the interfaces between the replacement assembly and retained furnace equipment.

Brazing and sintering

Identify process materials, potential deposits, supports and cleaning requirements. Review compatibility with the atmosphere and cycle before selecting materials.

Legacy equipment renewal

Start with the furnace model, available records and measured dimensions. A model name helps identify the equipment; replacement fit is confirmed against approved interfaces.

Connect the assembly, components and materials

Choose material-specific parts when the grade and individual component are already defined. For a coordinated internal assembly or a replacement project, use this hot-zone family and its dedicated pages.

Discuss the specified metal or alloy

Material grade, condition and compatibility with the furnace duty are confirmed for the approved design. Material melting points are not service-temperature ratings.

Questions before you send a drawing

What does a vacuum furnace hot-zone project include?

The agreed scope may be a complete internal assembly, a shield pack, heating bands, load fixtures or individual replacement parts. Start with the product page closest to your need, then identify the supplied and retained items in the drawing package.

Can you manufacture from drawings or develop a measured replacement?

Yes. Approved drawings can be used for manufacture; incomplete records can start a dimensional-survey and design review. Measurements, interfaces and material specifications must be resolved and approved before production.

Which materials should be specified?

State the existing or required grade and material condition. Molybdenum, tungsten and the separately specified MoLa and TZM options are reviewed against the component function and furnace duty; the photographs do not establish a grade or temperature rating.

Can I start with an older furnace and no complete drawing?

Send available equipment records, a measured sketch and photographs of the hot zone and connection points. Mark missing information so the survey method and replacement scope can be agreed.

Start with the drawing, measurements or existing hot zone

Send what is available and mark what still needs review: furnace information, geometry, material, process duty, quantity, destination and the replacement scope.
