Customized High Load Rectangular Flat Wire Die Spring and Mold Spring for Stamping Injection Molding

JIS die springs are compression springs used in industrial molds, metal stamping dies, and mechanical tooling systems. They provide the force required for repeated compression and recovery, helping support mold opening, return mechanisms, pressure application, and component ejection. Selecting the right spring specification is essential for maintaining smooth mechanical operation and achieving consistent production results.

Our JIS-style die springs are available in a variety of sizes and load options to accommodate different tooling structures. Customers can select suitable models according to outer diameter, free length, required compression force, working stroke, and installation space. For projects with special requirements, customized specifications can be evaluated based on technical drawings and application details.

• Reliable Spring Force: Designed to deliver compression force within the specified working range, supporting repeated movements in mold assemblies and industrial equipment.
• Multiple Size Options: Different diameters and lengths allow engineers to select springs that fit their tooling designs and available installation space.
• Durable Performance: Suitable material selection and appropriate heat treatment help maintain spring properties under specified operating conditions.
• Easy Identification: Color options may be available for different product series. Buyers should confirm the applicable color classification and load rating before selection.
• Flexible Customization: Selected dimensions, colors, and other specifications can be discussed according to customer requirements and manufacturing capabilities.

The quality of a die spring depends on material consistency, forming accuracy, heat treatment, and dimensional control. During production, appropriate inspection procedures help verify product dimensions and spring performance against agreed specifications. Load testing and other quality checks can be arranged according to the requirements of the selected product series.

JIS die springs are commonly used in stamping dies, progressive dies, punching tools, plastic mold mechanisms, automotive component production, and industrial machinery. They provide the compression force needed for mechanical return, mold movement, and other repetitive tooling operations.
