2Pcs Die Spring 3/4" OD X 1" Length Alloy Steel SMH4004 Mould Spring, Red

Size -Specification: SMH4004;Material: Alloy Steel;Color: Red;Outer Diameter: 3/4 inch;Free Length: 1 inch;Wire Size: 4.6 x 2.2 mm / 0.18 x 0.09 inch;Max Load: 185 lbs;Package Content: 2pcs x Die SpringMaterial - Constructed from alloy steel, the compression die spring resists deformation through repeated high-load cycles. The alloy steel composition delivers tensile strength and resilience, supporting consistent performance in stamping press and demanding industrial applications.Feature - The die spring design provides force in a compact footprint, suited for tight installation spaces. The rectangular wire section increases contact area and load capacity, ensuring uniform force across the compression stroke. The spring returns to its original free length after repeated cycles, delivering reliable force for continuous press operations.Application - Press die spring applications cover metal stamping, plastic injection molding, die casting, and progressive tooling systems. The spring serves as a return element in stamping presses, providing consistent stripping force for blanking and forming operations. Widely used in automotive, electronics, and appliance manufacturing tooling, the die spring fits diverse production needs.Note - Install the die spring with a guide rod and housing pocket matching the outer diameter. Avoid exceeding maximum load or compressing beyond solid height to extend service life. Verify spring orientation and seating before each press cycle.
