High elasticity is one of the primary requirements for mold springs, especially when a quick and efficient opening and closing of the mold are critical. Without the right level of elasticity, the mold spring would not be able to perform its job correctly, causing delays in the production process and potential defects in the finished product. The dynamic stability of mold springs is important. Mold springs must maintain their performance under constant movement, resisting fatigue, wear, and deformation, which could result in reduced effectiveness and malfunctioning of the mold. The pressure from multiple mold cycles can take a toll on the spring, so choosing materials with strong fatigue resistance is essential for ensuring that the mold spring operates reliably throughout the production process.
