Metals used in production processes accumulate unwanted residual stresses within their internal structures during operations such as casting, forging, machining, welding, and heat treatment. These stresses can cause the material to deform, crack, or fatigue earlier than expected in later stages.

    Stress relief processes enable the controlled reduction of internal stresses in both non-hardened materials (e.g., after rough machining) and hardened–worked materials (in a fatigued state), as well as after processes like welding, wire EDM, and sinker EDM.

    Applying stress relief, especially to molds and parts operating at high temperatures (e.g., in metal injection molds), extends the material’s lifespan, enhances dimensional stability, and ensures operational reliability.
