Die Cast Spring O Ring With 1 Inch Inner Diameter
A sprung O ring with a 1 inch inner diameter and a 4 mm section, formed in iron. Quoting both the inner diameter and the thickness matters here, because a 1 inch ring in a thin section will pull oval under a hanging strap. Minimum 500 pieces per colour and production runs 2 to 7 days.

How This Part Is Produced
Six steps inside one factory, from the mould to the packed carton.
Technical Features
- Die cast zinc alloy or formed iron with an optional sprung gate
- Inner diameter and wire thickness both specified, because either alone can mislead

Quality Control
- Incoming zinc, brass, iron and stainless material checked against the grade ordered
- First article from each mould compared with the approved sample before the run starts
- Dimensional check on inner width and thickness during casting and stamping
- Plating thickness and colour compared against the approved colour plate
- Spring and swivel action tested by hand on hooks, snaps and side release buckles
- Counted, bagged and cartoned with the order's own packing list
Customisation Options
- Size or inner width changed on an existing catalogue style with no mould fee
- Finish chosen from nickel, gunmetal, black nickel, gold, light gold, rose gold, antique brass and rainbow
- Logo etched or embossed where the part has a flat large enough to carry it
- Painted or enamel colour where a plated metal tone will not match the brand colour
- Free 3D design from a photo or a physical sample if you have no drawing

Use Guide

- For a hanging charm choose a sprung O ring so the end user can change it
- Check the gate closes flush against the ring before approving a batch
| Compared with | What changes |
|---|---|
| Split key ring | A split ring is cheaper but scratches leather and is awkward to open by hand |
| D ring | A D ring holds a square pull, while an O ring allows the strap to swing |
| Oval spring ring | An oval gives a longer gate opening for thick webbing while taking the same wire section |

What Is the Difference Between an O Ring and a Spring O Ring
A plain O ring is closed, so the strap has to be sewn in. A spring O ring has a sprung gate, so the end user can clip and unclip the strap or charm.
