You've got a technician standing in front of an electrical cabinet in a dusty factory, and what it does is swing that heavy door open and closed a thousand times a shift without squeaking or sagging—that's the real test, and these K Series hinges handle it because the anodized surface on the aluminum alloy ones is actually harder than the base metal, so it resists scratching form constant use.
We've been moving these for about eight years now, and most buyers go with the SUS304 stainless steel for outdoor application since it holds up better against moisture, but the zinc alloy option is pretty much fine for indoor instrument panels where you don't need that extra corrosion resistance, and you'll save roughly 15% on the unit cost.
The lead time for samples is usually 10 to 15 days, which is tight enough for most OEM schedules, but bulk orders take 20 to 30 days depending on the finish you pick—polished silver moves faster than anodized black because that black anodizing requires an extra dye bath step (check lead time before finalizing your PO).
10-year manufacturing defects, but it doesn't cover if someone overtightens the screws and strips the mounting holes—that's just user error, and we've seen it happen more often with the zinc alloy than the stainless steel version, so for heavy-duty loads I'd steer you toward the SUS304 even if it costs a bit more.
One thing buyers don't always think to ask is that the screw hole spacing on the K Series is standardized to 64mm center-to-center, which matches most European electrical cabinet frames, but if you're doing a custom panel layout you'll need to confirm that dimensoin before we start tooling samples.
Anyway, the anodized finish isn't suited for food-grade environments where you need a non-porous surface that can be sanitized with harsh chemicals—that's a different product line entirely, but for industrial equiment cabinets it's actually better than polished because of that it doesn't show fingerprints.
We don't have a strict MOQ for standard models, but for OEM/ODM with custom specs, we typically start at 500 pieces per design. We can discuss smaller quantities for sample orders though.
Yes, we can include our ISO9001 certificate with every bulk shipment. Just let your sales contact know, and we'll attach it to the packing list or send it digitally.
The black anodized finish is limited to aluminum alloy. Stainless steel hinges come in a polished silver finish or brushed option, but we can't anodize stainless steel.
We pack them in sturdy cardboard boxes with foam dividers between layers, then seal everything in plastic wrap. For larger quantities, we use palletized crating to keep them secure.
Custom colors or engraving add about 5-7 days to the standard lead time. So for samples, expect 15-20 days, and for bulk, 25-35 days. We'll confirm the exact timeline once we finalize the specs.
