Stress Relieving Oven
ZonHoo stress relieving ovens are engineered to reduce internal stresses in metal parts, preventing distortion, cracking, and ensuring consistent quality during post-production processes. Whether your parts are forged, welded, or machined, a stress relieving oven helps stabilize materials by carefully controlling heating and cooling profiles, promoting uniform stress elimination across each load.
As an OEM/ODM manufacturer, ZonHoo designs the stress relief process, control system, and temperature cycling specifically for your materials and production needs. We offer an RFQ-ready scope—temperature range, chamber configuration, thermal cycling profile, and utilities—along with documentation scope to streamline project approval and integration.
- Stress relief through controlled heating and cooling cycles
- Uniform stress elimination to prevent cracking and distortion
- Precise temperature control for material stabilization
- Repeatable results with stable thermal profiles
- Recipe control and data logging (opt.)
- RFQ-ready delivery: drawings, FAT/SAT, acceptance checks
When to Choose a Stress Relieving Oven
Choose a stress relieving oven when your key goal is to eliminate internal stresses in metal components and prevent material distortion or cracking:
- You need to stabilize materials after cold working, welding, forging, or machining
- Internal stresses must be relieved to improve material integrity and prevent distortion during further processing
- You require uniform heating to prevent uneven stress relief across the load
- Your process requires controlled cooling to avoid rapid quenching or thermal shock
- You need repeatable results with stable heating and cooling cycles across shifts
- Tight temperature tolerance is essential to prevent material damage during stress relieving
If your primary goal is softening materials for shaping or stress elimination, use an Annealing Oven; if you need high-temperature drying, use a High Temp Drying Oven; if curing/volatiles are involved, use a Curing Oven.
