Heat Treatment Fixtures Manufacturer | FH®

What is a Heat Treatment Fixtures | FH®?

A Heat Treatment Fixtures | FH® is a supporting, positioning, and securing device designed specifically for use in high-temperature furnaces. It stabilizes the workpiece during the heat treatment process, prevents deformation, and ensures uniform heat flow.

1. Functional Positioning: Provides a reliable loading platform in a variety of furnace types, including vacuum, chamber, push-type, pit-type, and lamp-type furnaces (such as Ipsen, Aichelin, ECM, KGO, NITRIX, AFC, IVA-SCHEMTZ, CODERE, and MATTASA).
2. Structural Features: Utilizing a lost-wax casting process, it achieves a smooth and flat surface. Combined with a patented high-temperature-resistant alloy, it achieves long-term stability in extreme temperature cycling and corrosive environments.
3. Improved Efficiency: Through precise load design, it increases loading capacity, reduces rework due to workpiece movement, and significantly reduces heat treatment batch costs.
What are common Heat Treatment Fixtures | FH® materials?

High-temperature alloys – Based on the company's proprietary heat-resistant alloy formula, these materials maintain strength above 1200°C and are suitable for vacuum and high-temperature furnaces.

1. Carbon Fiber Reinforced Carbon (CFC) – Considered the industry benchmark in vacuum heat treatment, they offer excellent dimensional stability and significantly reduce workpiece distortion.

2. Refractory Ceramics and High-Temperature Steels – Commonly used in open furnaces or where flame impingement resistance is required, ensuring the fixture itself does not become a source of heat loss.

3. Specialty Coated Steels – Surface carburizing, nitriding, or plasma spraying enhances corrosion resistance and extends service life, making them suitable for oil or salt bath heat treatment environments.
