Cellulose acetate sheet, usually just called CA board. It's got a natural shine, so no painting needed. Thickness runs 3mm to 8mm depending on the clip size — bigger claw clips need thicker board or the grip won't hold.
Bad grinding. Raw acetate comes out of the cutting machine with hard, square edges. It needs two rounds of grinding, rough then fine, to round them off. Some smaller factories skip the second pass to save time. Easiest way to check: run a fingernail along the edge of a sample before placing a bulk order.
Two ways. Mold pressing for large runs — cheaper per piece, but tooling costs upfront. Or laser cutting / engraving after shaping, which works better for small custom batches but costs more per unit. Mostly comes down to order size.
Welding. Metal parts are usually stainless steel or alloy for spring tension. Weld placement matters a lot — off-center welds mean uneven pressure, and the clip cracks after a few uses. Decent factories pull-test the joint before shipping; cheaper ones often don't.
Polishing, right after grinding. Workers run the clips through buffing wheels with polishing compound — a few passes, not just one quick swipe. That's what gets rid of the tiny scratches left from grinding. It also smooths out any rough spots that got missed earlier on the edges. Skip this step or rush it, and the clip just looks flat, kind of dull. Do it properly and it has that wet-glass shine you see on the good stuff.
