Jis Die Springs provide heavy-duty support and long life in high-cycle stamping and forming dies.
Us Die Springs deliver reliable force and resistance to fatigue in demanding industrial press applications
Compression Springs absorb shocks and store energy in vehicle suspension systems and machinery
Tension springs provide constant pulling force to counterbalance weights, like in garage doors or machinery guards
Torsion springs apply rotational torque for closing mechanisms in clamps, doors, and levers
Die springs are heavy-duty compression springs that are commonly used in die machinery, stamping presses, and other heavy-duty industrial applications. They are designed to withstand high load and provide reliable and consistent performance.
Die springs offer several benefits, including high load-bearing capacity, long service life, efficient energy absorption, and resistance to fatigue and wear. They provide consistent force throughout their working range and are available in various sizes and force ratings to meet specific application requirements.
When selecting a die spring, you need to consider factors such as the required load capacity, working environment conditions, spring size and type, and the desired deflection and force specifications. It is recommended to consult with a spring manufacturer or engineer to ensure you choose the right spring for your application.
Die springs are typically made from alloy steel to ensure durability. Specific alloys such as 65Mn and 55SiCr are widely used for their high tensile strength and fatigue resistance.
Die springs are often color-coded to distinguish between different force ratings. The commonly used color codes are lightest load (blue), light load (yellow), medium load (red), heavy load (green), and extra-heavy load (brown).
Yes, die springs can be customized to meet specific load capacities, sizes, and force specifications. Customization options include altering the outer diameter, inner diameter, wire size, and length to suit your application needs.
The lifespan of die springs depends on several factors, such as the application’s operating conditions, load profile, and proper maintenance. However, die springs are designed to have a long service life and can withstand millions of cycles under normal operating conditions.
Die springs are primarily designed for heavy-duty industrial applications. While they may be used in some non-industrial applications, it is recommended to consult with a spring manufacturer or engineer to determine the suitability of die springs for your specific application.
Yes, Dingli Spring focuses on serving corporate customers.

A die spring can meet its initial load requirement and still cause trouble after it is installed in a production tool. Free-height loss, uneven wear, cracking, or reduced return force may appear only after repeated cycling. That is why die spring fatigue testing should be connected to the real tooling condition, rather than treated as […]
Mid-year tooling maintenance is when most replacement die spring orders are placed, and it is also when the most expensive selection mistakes happen. The shop pulls a worn spring out of a die, sees it is “the green one,” and orders the next box of green springs. The new spring fits the cavity but the […]
