Small Compression Spring Ballpoint Pen Springs

Technical specifications

Customization guide

Adjustable parameters include diameter, wire thickness, and free length to meet specific force requirements or fit constraints. For example, thinner wires reduce compression force for lightweight applications, while thicker wires enhance load capacity for heavy-duty use.

Supplier's note

1. Technical Breakthroughs:

   • Material Innovation: Stainless steel construction offers triple the corrosion resistance of standard carbon steel, extending lifespan in humid environments.
   • Uniform Coiling: Precision manufacturing ensures ±2% spring rate consistency, critical for applications like pen mechanisms requiring repeatable force.
   • Scalable Design: A 15mm diameter max size accommodates heavy-duty industrial tools while maintaining compact form factors for pens.

2. Optimal Version Selection:

   • Base Model: Ideal for standard ballpoint pens or low-force applications where cost efficiency is prioritized.
   • Advanced Model: Suited for mechanical pencils or precision instruments needing enhanced durability (e.g., 20% higher spring rate than competitors).
   • Pro Model: Best for industrial machinery or extreme environments (e.g., automotive parts) where 500hr salt spray resistance ensures reliability.

With the Pro Model’s premium corrosion resistance, you can ensure springs withstand aggressive chemicals in lab equipment. Pair this with its high spring rate to deliver stable performance in heavy-duty tools.
