Rectangular Section Die Spring with High Load Capacity for Precision Mold Applications and Custom OEM Manufacturing

Rectangular Section Die Spring is a high-performance compression spring specifically designed for precision molds, stamping dies, injection molds, and industrial tooling applications. Featuring a rectangular wire cross-section design, this type of die spring provides higher load capacity, improved fatigue resistance, and longer service life compared with conventional round wire springs.

Manufactured from premium alloy spring steel materials through advanced CNC coiling, heat treatment, and precision grinding processes, our rectangular section die springs deliver stable spring force, excellent elasticity, and reliable performance under high-pressure working conditions.
