Manufacturing Capability
CHEMETAL USA manufactures tungsten and molybdenum high-temperature furnace components from plate, sheet, strip, foil, rod, wire, and other refractory metal forms. Our manufacturing capability includes precision machining, forming, fabrication, joining, and assembly for components used in vacuum furnaces, controlled-atmosphere furnaces, hot zones, and related thermal processing systems.
Depending on component structure and service requirement, manufacturing may involve machining for fasteners, supports, spacers, and structural parts, or fabrication for heat shields, chamber parts, crucibles, boats, trays, and carriers. Material and process route are selected according to operating temperature, furnace atmosphere, structural load, thermal cycling, and expected component life, so that each part is made for actual furnace service.
Component Types and Manufacturing Focus
Heating Elements
Heating elements are manufactured according to power input, geometry, assembly method, and service temperature. Stable geometry, reliable joining, and dimensional consistency are important because element structure affects both heat generation and heat distribution inside the hot zone.
Heat Shields and Radiation Shields
Heat shields are fabricated to reduce heat loss and improve thermal efficiency. Their manufacture requires attention to flatness, hole location, spacer alignment, layer consistency, and assembly stability, especially in multi-layer shield structures.
Crucibles, Boats, Trays, and Carriers
Crucibles, boats, trays, and carriers are selected according to process requirement, charge condition, furnace atmosphere, and service temperature. These parts require sound fabrication quality, dimensional control, and resistance to distortion during repeated thermal cycling.
Fasteners and Structural Hot-Zone Parts
Fasteners, spacers, holders, rails, and structural support parts are used to maintain assembly fit, component alignment, and dimensional stability inside the furnace system. These parts rely on precision machining, correct material selection, and compatibility with the existing hot-zone structure.
Built for High-Temperature Service
High-temperature furnace components must do more than match nominal dimensions. In vacuum and controlled-atmosphere furnace service, components are expected to fit correctly within hot-zone assemblies and remain functional under repeated heating cycles, structural loading, and maintenance intervals.
For this reason, furnace component manufacturing must consider not only dimensions and tolerances, but also material condition, part geometry, assembly fit, and service environment. Depending on the application, components may be made from tungsten, molybdenum, TZM, molybdenum-lanthanum, or other refractory metal materials.
Material selection depends on furnace structure, operating temperature, furnace atmosphere, service environment, maintenance requirements, and expected component life.
Furnace Component Uses
Tungsten and molybdenum furnace components manufactured by CHEMETAL USA are used in applications such as:
- Vacuum and controlled-atmosphere furnaces
- Hot-zone systems
- Crystal growth equipment
- Sintering and thermal processing systems
- Heat treatment furnaces
- Furnace maintenance, rebuilding, and replacement projects
These applications require components that are matched to furnace structure, service temperature, and maintenance requirements rather than treated as general fabricated metal parts.
More Than Manufacturing
In addition to component manufacturing, CHEMETAL USA also supports component repair, replacement, hot-zone rebuilding, and custom replacement part manufacturing for furnace maintenance and service. This broader involvement helps us understand furnace components not only as individual parts, but also as functional parts within complete furnace systems and hot-zone assemblies.
