Do there has a certain relative between thickness and diameter of the snap domes? Generally there has a certain relationship.
Snap domes material generally used is stainless steel 301 and 304, the shape we have circle, cross, triangle and oblong, with diameters from 3mm to 20mm. Here you can have a look at their relationship:
1. Diameter: 3mm-5mm; Material thickness: 0.04mm-0.06mm;
2. Diameter: 6mm-8mm; Material thickness: 0.06mm-0.08mm;
3. Diameter: 9mm-12mm; Material thickness: 0.09mm-0.1mm;
4. Diameter: 16mm-20mm; Material thickness: 0.12mm.
You see, the larger snap dome (metal dome) in diameter, the thicker material it will be used. The choice of material determines the quality and force of the product. If you want to know which types of material thickness your snap domes used, you can contact us directly.
