OD 12mm Die Springs — Reliable Compression Force for Mould & Industrial Applications

Engineers and toolmakers who rely on consistent spring-back force know the frustration of springs that fatigue prematurely or fail to meet load specifications. These OD 12mm die springs are engineered for mould tooling, stamping fixtures, and mechanical assemblies where repeatable compression performance is non-negotiable. Whether you are building a new injection mould or replacing worn springs in a progressive die, these components deliver the controlled resistance your application demands.

Each spring features an outer diameter of 12mm and is available in four inner diameter options — 6.1mm, 6.3mm, 6.5mm, and 6.6mm — to suit different guide pin sizes. Body lengths range from 10mm to 300mm (approximately 0.39 in to 11.81 in), and load ratings span light, medium, and heavy duty to match your deflection and force requirements. Springs are offered in five color-coded load grades: Yellow (light), Blue (medium), Red (heavy), Green (extra heavy), and Brown (ultra heavy), following standard die spring color conventions.

Typical use cases include injection mould stripper plate actuation, stamping die lifter mechanisms, CNC fixture clamping systems, and general-purpose compression spring replacement in industrial machinery. The compact OD 12mm form factor makes these springs well-suited for tight-clearance tooling where space is limited but reliable spring force is essential.

⚙️ Compatible with standard 12mm OD die spring pockets. Match inner diameter to your guide pin diameter. Color indicates load grade per ISO 10243 / JIS B 5012 conventions.

✅ Key Features of These OD 12mm Die Springs

🎨 Color-Coded Load Grades

Five colors — Yellow, Blue, Red, Green, and Brown — identify light through ultra-heavy load ratings at a glance, reducing assembly errors in multi-spring tooling setups.

📐 Wide Size Range

Body lengths from 10mm to 300mm (0.39–11.81 in) and four inner diameter options (6.1mm, 6.3mm, 6.5mm, 6.6mm) cover the majority of standard 12mm OD die spring applications.

🔁 Consistent Compression Performance

Wound to maintain stable spring rate across repeated compression cycles, supporting reliable stripper plate return and lifter actuation in production tooling.

🔩 Standard Die Spring Geometry

OD 12mm profile fits standard die spring pockets and guide pin configurations used in injection moulds, stamping dies, and fixture plates.

📦 Flexible Pack Quantities

Available in single-piece (1pc) and five-piece (5pcs) packs, allowing you to order exactly what you need for prototyping, maintenance, or production restocking.

🏭 Broad Application Compatibility

Suited for injection mould stripper actuation, progressive die lifters, CNC fixture clamping, and general industrial compression spring replacement across a range of machinery types.

❓ Frequently Asked Questions

How do I choose the correct inner diameter for my application?

The inner diameter (ID) should match or slightly exceed your guide pin diameter to allow free sliding without excessive lateral play. This product offers IDs of 6.1mm, 6.3mm, 6.5mm, and 6.6mm. Select the ID closest to your guide pin OD while ensuring the spring can slide freely without binding.

What does the color of the die spring indicate?

The color identifies the load grade following standard die spring conventions: Yellow = Light load, Blue = Medium load, Red = Heavy load, Green = Extra heavy load, Brown = Ultra heavy load. Selecting the correct load grade ensures the spring delivers the required force at your specified deflection without over-stressing the spring body.

How do I select the correct body length?

Body length should be chosen based on your required free length and working deflection. A general guideline is to limit deflection to 20–30% of free length for light loads and up to 40–50% for heavy loads, depending on the spring grade. Measure your pocket depth and required stroke to determine the appropriate free length. Available lengths range from 10mm to 300mm.

Are these die springs suitable for high-cycle production tooling?

These springs are designed for compression die spring applications including production mould tooling and stamping dies. For very high-cycle applications (millions of cycles), ensure you are operating within the recommended deflection range for the selected load grade to maximize service life. Contact us to confirm suitability for your specific cycle requirements.

Can I use these springs in corrosive or high-temperature environments?

Standard die springs are intended for typical industrial tooling environments. If your application involves elevated temperatures, chemical exposure, or high humidity, please contact us to confirm material and finish compatibility before ordering.

Should I order 1pc or 5pcs?

The 1pc option is ideal for prototyping, testing, or single-spring replacement. The 5pcs pack offers better value per unit for production tooling builds, maintenance stock, or applications requiring multiple springs of the same specification. Both options ship the same spring — only the quantity differs.

How do I confirm the spring fits my existing die spring pocket?

Measure your pocket bore diameter (should accommodate OD 12mm with a close fit), pocket depth (determines maximum free length), and guide pin diameter (determines required ID). Cross-reference these measurements with the variant options available. If you are unsure, contact us with your pocket and pin dimensions for confirmation.
