Pull test: welded plastic eyelet vs. metal grommet strength
A side-by-side pull test: a Carmo HF-welded plastic eyelet against a standard metal grommet in PVC-coated fabric, pulled until the fabric tears. The welded eyelet fuses with the foil across the whole flange instead of being punched through it: in Carmo's workshop pull test on PVC-coated nylon (600 g/m²), a single welded eyelet held about three times the force of a metal grommet, and a double-welded eyelet about four times. In-house test with an uncalibrated newtonmeter: indicative, not a certified standard test; ask Carmo for a test on your own material. The reason to weld eyelets, not set metal ones.

Carmo workshop pull test: an HF-welded plastic eyelet against a metal grommet, in PVC-coated fabric. The metal grommet is punched through the fabric; it grips only the rim it clamps. Under load, the grommet tears out of the fabric. The welded eyelet is fused to the coating across its whole flange. The weld spreads the pull into the fabric; it holds far more force before tearing. Carmo in-house test, uncalibrated newtonmeter: indicative. Ask for a test on your material.
