Heat Treatment Rack | Custom Furnace Fixture Rack Manufacturer – FH® Alloy
Custom Heat Treatment Racks for High-Temperature Furnace Applications

FH® Alloy, a brand of Wuxi Junteng Fanghu Alloy Technology Co., Ltd., manufactures custom heat treatment racks for demanding industrial furnace applications.

Designed for high-temperature service, our heat treatment racks are used to support, position, and separate workpieces during heat treatment cycles. With an open-frame structure and multi-point locating design, these racks help improve loading efficiency, maintain part spacing, and promote uniform heat circulation inside the furnace.

Whether you need a rack for carburizing, annealing, hardening, normalizing, or other thermal processes, FH® can provide a custom solution based on your furnace conditions and workpiece requirements.

Product Features
Stable Workpiece Positioning
This type of heat treatment rack is designed with multiple locating and supporting points to keep parts in the correct position during the entire heat treatment process. It helps reduce part-to-part contact and supports more consistent processing results.
Open Structure for Better Heat Circulation
The open-frame design allows furnace atmosphere and heat to circulate more freely around the loaded parts, which can improve heating efficiency and temperature uniformity.
Designed for Repeated Thermal Cycling
Heat treatment fixtures are exposed to repeated cycles of heating, soaking, cooling, and reloading. FH® designs each rack to withstand thermal fatigue and high-temperature service conditions.
Stackable / Multi-Layer Loading Capability
This rack structure can be integrated into multi-layer loading systems to improve furnace space utilization and support higher production efficiency.
Custom Structure Available
The support positions, spacing, frame layout, and overall dimensions can all be customized according to your product shape, loading quantity, and furnace process.
