Annealing Oven

ZonHoo annealing ovens are engineered to provide uniform heat treatment for material softening, stress relief, and microstructure adjustment in metals and alloys. Whether your material requires thermal cycling to reduce brittleness, improve ductility, or relieve internal stresses, a annealing oven offers repeatable results with precise temperature control and stable heating profiles.

As an OEM/ODM manufacturer, ZonHoo designs each annealing oven configuration, control system, and heating process around your materials and processing requirements. We provide an RFQ-ready scope—temperature range, chamber size, thermal cycling profile, and utilities—along with documentation scope to accelerate project approval and integration.

• Material softening and stress relief through controlled heating
• Uniform heating and thermal cycling for microstructure adjustment
• Precise temperature control for process consistency
• Repeatable results with stable temperature distribution
• Recipe control and data logging (opt.)
• RFQ-ready delivery: drawings, FAT/SAT, acceptance checks

Choose an annealing oven when your key goal is material softening and stress relief through thermal cycling:

• You need to soften metals and alloys to adjust their mechanical properties (increase ductility, reduce brittleness)
• Internal stresses need to be relieved after cold working, forging, or casting to prevent cracking or warping
• Uniform heating is required to achieve a consistent temperature profile across the load
• You need to control microstructure through a specific thermal cycle with temperature ramps and holds
• You require repeatable results with consistent heating, cooling, and cycling across multiple batches
• Tight temperature tolerance is required to prevent material degradation or damage

If your primary goal is surface hardening or strengthening, use a Tempering Oven; if your primary goal is aging of aluminum or other alloys, use an Aging Oven; for high-temperature drying, use a High Temp Drying Oven.
