How to use CNC spring machine to make paper clips
*How to use cnc spring machine to make paper clips ?
A paper clip is a simple yet ingenious tool, and its production can be replicated using a spring-coiling machine. Here’s a step-by-step overview of the process:
1. Material Selection: Begin with a spool of steel or galvanized wire, chosen for its balance of flexibility and strength. The wire’s diameter typically ranges between 0.8mm to 1.2mm.
2. Machine Setup: Load the wire into a spring-coiling machine. Adjust the machine’s settings to match the desired paper clip dimensions—most clips require two full loops (for gripping paper) and a third partial loop for structure.
3. Wire Feeding & Bending: The machine feeds the wire through a series of guides and rollers. A rotating mandrel or bending arm shapes the wire into the iconic double-loop design. Precision is key: The first two loops are tightly coiled to grip paper, while the final bend creates the clip’s "backbone."
4. Cutting & Finishing: Once shaped, the wire is cut to length, leaving smooth edges. Heat treatment may be applied to strengthen the metal, followed by coating (e.g., plastic or nylon) for corrosion resistance or aesthetics.
5. Quality Check: Inspect clips for consistent shape, tension, and durability. Defective units are recycled.
**Why Spring Machines Work**: These machines excel at rapid, uniform bending—producing hundreds of clips per minute. By adjusting mandrel size and feed speed, manufacturers can create various clip sizes or even custom designs.
While simple in concept, this process blends engineering precision with material science to turn a humble wire into an organizational staple.
