ISO 10243 Die Springs – German Standard Mold Springs

ISO 10243 die springs are high-performance compression springs designed for stamping dies, molds, press tools, and other industrial tooling applications. Manufactured with rectangular-section spring wire, these die springs provide high spring force in a compact installation space and are suitable for applications requiring reliable and repeated compression performance.

Designed according to ISO 10243 requirements, the springs are available in different load categories, including light, medium, heavy, and extra-heavy load options. Color coding helps users quickly identify the spring load class and select the appropriate spring for specific tooling requirements.

Our ISO 10243 mold springs are available in a wide range of outside diameters, free lengths, spring rates, and load capacities. They can be used with guide pins and spring pockets in stamping dies, progressive dies, injection molds, press tools, and automated tooling systems.

How to Select the Right ISO 10243 Die Spring

When selecting an ISO 10243 die spring, consider the required spring force, working stroke, free length, outside diameter, installation space, and expected service conditions. The spring rate and working deflection should be matched to the actual tooling requirements rather than selecting a spring only by color or maximum load.

For applications requiring long service life, it is recommended to operate the spring within an appropriate working deflection range and avoid excessive compression.

FAQ

Q1: What is an ISO 10243 die spring?
A: An ISO 10243 die spring is a rectangular-section compression spring designed for use in pressing tools, dies, molds, and other tooling applications. ISO 10243 specifies housing dimensions and color coding for these springs.

Q2: What is the difference between ISO 10243 and ordinary compression springs?
A: ISO 10243 die springs are specifically designed for high-load tooling applications and use rectangular-section spring wire. Their standardized installation dimensions and load classification make them suitable for compact die and mold assemblies.

Q3: What load classes are available?
A: ISO 10243 classifies springs according to spring rates, including light, medium, strong, and extra-strong categories. The corresponding color coding helps identify the load class.

Q4: Where are ISO 10243 springs used?
A: They are widely used in stamping dies, sheet metal forming tools, injection molds, press tools, and other applications where high spring force is required in limited installation space.

Q5: Can you provide custom die springs?
A: Yes. Custom solutions can be considered based on required dimensions, spring force, working stroke, free length, material, and application conditions.

Q6: How do I choose the correct die spring?
A: Provide the required outside diameter, free length, working stroke, required load, installation space, and application information. These parameters can be used to determine a suitable spring specification.
