Which Accessory Do You Need?

Select the accessory based on what problem you're solving in your die spring assembly:

🛡️

Protect Die Plates from Spring Wear

Spring end surfaces grind into plate surfaces over millions of cycles, creating pits and dimensional loss.

Recommended:Spring Washers (SSWA/SSWB/SSWC) — hardened steel washers between spring end and plate surface
🎯

Prevent Spring Lateral Migration

Springs shift sideways in oversized bores, causing uneven force distribution and accelerated wear.

Recommended:Spring Guide Pins — center the spring in the bore throughout the compression cycle
⚠️

Contain Broken Spring Fragments

Broken heavy-duty die springs produce high-energy fragments that can jam the die or injure operators.

Recommended:Spring Cages (Lamina/DANLY) or Spring Guards (DANLY) — fully enclose the spring
📌

Fix Spring Position During Die Changes

Springs fall out or shift position when the die is opened, requiring manual repositioning during setup.

Recommended:Spring Retainers (DANLY/LEMPCO) — lock spring position for quick die changes
🔼

Elevate Strip Between Progressive Die Stations

Metal strip needs to be lifted between stations to advance without dragging on the die surface.

Recommended:Stock Lifters (Heavy/Mini) — spring-powered strip elevation with automatic return

Accessory rule: At minimum, every die spring assembly should include washers. Add guide pins for Ø10+ springs. Add cages/guards for heavy and extra heavy duty. For detailed sizing, see our Why You Need Spring Accessories — Washers, Guide Pins, and Cages Explained.

Spring Compatibility Reference

Each accessory is designed for specific spring types and sizes. Verify compatibility before ordering:

Matching rule: Always verify the spring inner diameter before selecting guide pins, and the spring outer diameter before selecting cages. For detailed matching procedures, see our How to Match Spring Accessories to Your Die Spring Diameter and Type.

About Spring Accessories

Spring accessories are essential for proper die spring installation, performance optimization, and safety. Our 16-product range covers washers, guide pins, retainers, cages, guards, stock lifters, stock pushers, and roller guides from MISUMI, DANLY IEM, Lamina, and LEMPCO. These components extend die spring service life, improve force consistency, and ensure safe operation in high-volume stamping.

Frequently Asked Questions

SSWA: Standard flat washer for general use with most die spring sizes. SSWB: Wider contact area for larger-diameter springs requiring more surface protection. SSWC: Thicker profile for heavy-duty springs requiring maximum plate protection. All three are hardened steel designed to resist spring end grinding wear.
Add cages/guards whenever using heavy-duty (red) or extra heavy-duty (yellow) die springs, especially at deflections above 80% of rated maximum. These springs store significant energy — a fracture releases high-velocity fragments that can jam the die, damage precision surfaces, or injure operators. Cages/guards fully contain the spring to eliminate these risks.
The guide pin outer diameter should pass freely through the spring's inner diameter with 0.5-1mm clearance on each side. Check the spring's ID specification, then select a guide pin with OD ≤ (spring ID - 1mm). Too tight = friction increases spring stress; too loose = insufficient centering guidance.
Stock lifters use internal die springs to elevate the metal strip between die stations, allowing free advancement without surface dragging. Available in heavy-duty (Lamina) and mini sizes. Roller stock guides (DANLY IEM) use rollers instead of sliding surfaces to reduce friction and improve strip alignment accuracy at high speeds (>200 SPM).

Frequently Asked Questions

Which type of spring washer (SSWA, SSWB, or SSWC) should I use for my die springs?+
SSWA: Standard flat washer for general use with most die spring sizes. SSWB: Wider contact area for larger-diameter springs requiring more surface protection. SSWC: Thicker profile for heavy-duty springs requiring maximum plate protection. All three are hardened steel designed to resist spring end grinding wear.
When should I add a spring cage or guard to my die setup?+
Add cages/guards whenever using heavy-duty (red) or extra heavy-duty (yellow) die springs, especially at deflections above 80% of rated maximum. These springs store significant energy — a fracture releases high-velocity fragments that can jam the die, damage precision surfaces, or injure operators. Cages/guards fully contain the spring to eliminate these risks.
What size spring guide pin do I need for my die spring diameter?+
The guide pin outer diameter should pass freely through the spring's inner diameter with 0.5-1mm clearance on each side. Check the spring's ID specification, then select a guide pin with OD ≤ (spring ID - 1mm). Too tight = friction increases spring stress; too loose = insufficient centering guidance.
What are stock lifters and roller stock guides used for in progressive dies?+
Stock lifters use internal die springs to elevate the metal strip between die stations, allowing free advancement without surface dragging. Available in heavy-duty (Lamina) and mini sizes. Roller stock guides (DANLY IEM) use rollers instead of sliding surfaces to reduce friction and improve strip alignment accuracy at high speeds (>200 SPM).
