This is a full collection of stamped cable clamps and conduit clips produced on 25-ton to 80-ton high-speed presses at our Dongguan factory. You get a consistent ±0.05mm dimensional tolerance, a 28–32 HRC hardness range on carbon steel parts, and a standard lead time of 7 days for non-stock sizes. Every part is deburred and passivated before packing, so you can drop them into your assembly line without rework.
Our dies are built with D2 tool steel and ground to a clearance of 4% to 6% of material thickness. That clearance is the difference between a clean shear edge and a torn burr. We run progressive dies at 150–300 strokes per minute, and each station is monitored by a load sensor that flags any deviation above 0.5% of nominal tonnage. The result: a stamped cable clamp that snaps onto a conduit with a repeatable grip force, not a loose or cracked fit.
You are not stuck with one steel. We stock DC01 cold-rolled steel (0.5mm to 3.0mm), SUS301 spring steel, and SUS304 stainless. For clips that need to bite into a conduit, we use 65Mn spring steel tempered to 42–46 HRC. If you are in a marine or chemical environment, we add zinc-nickel plating (8–12 microns) or a clear passivation that passes a 72-hour neutral salt spray test per ASTM B117. All coils come with mill certificates, and we can share them with your QC team before production.
A conduit clip is a simple bend, but springback kills accuracy. We over-bend by 2° to 4° depending on the yield strength of the coil, and we calibrate that angle on the first 50 pieces of every run. Our in-house hardness tester (Rockwell B and C) verifies that the material is within spec before we touch the die. For a 1.0mm DC01 clip, you get a bend radius that matches your conduit outer diameter within 0.1mm, so the clip stays put under a 5 kg pull test.

Raw stamped edges are sharp enough to cut wiring insulation. We run every part through a vibratory finisher with ceramic media for 30 to 45 minutes, which brings edge radii to 0.1mm – 0.2mm. Then we wash and dry the parts in a degreasing line that removes all stamping oil. If you skip this step, your clamps will chafe cables during thermal cycling. We do not skip it. For high-volume orders over 50,000 pieces, we add a secondary tumbling step to ensure zero loose burrs inside the clip channel.
We pull 5 pieces from every 1,000-piece lot. Those 5 go to our 2.5D optical projector for hole position, width, and bend angle. One piece goes to the CMM for a full profile scan against your 3D PDF or STEP file. We keep the inspection report for 3 years, and we email it to you with the packing list. If a lot fails, it gets quarantined and reworked — it does not ship. That is why our return rate on stamped clamps is below 0.3% over the last 12 months.
If your conduit is an odd metric or inch size, we make a new progressive die in 15 days. Send us a sample of the conduit or a drawing with the OD and wall thickness. Our engineers will design a clip with a 0.2mm interference fit — that means the clip squeezes the conduit slightly, which prevents rattling. Prototypes are delivered in 5 days, and the prototype cost is deducted from the full tooling quote if you proceed. We have built dies for conduit sizes from 6mm to 50mm, including double-loop clamps for fuel lines.
No MOQ — you can order 1 piece for a prototype or 1 million for production, and the unit price adjusts accordingly.
Yes, we modify the progressive die to match your hole spacing, slot width, or mounting tab geometry, with a 15-day tooling lead time.
We use a Rockwell C tester on a flat test tab stamped from the same coil, and we log the result on the lot inspection sheet.
Repeat orders on existing tools ship in 5 days if the material is in stock, and we keep DC01 and SUS304 coils on the floor at all times.
Automated assembly lines hate variance. Our stamped cable clamps are measured for grip force on a test mandrel that simulates your conduit. We hold grip force within ±10% of the nominal value across a production lot. That means your robotic arm inserts the conduit with the same push force every cycle, and the clamp does not deform or loosen after 100 insertion cycles. For harness assembly, we also offer pre-lubricated clips that reduce insertion force by 20% without affecting retention.
Before you finalize your material spec, check our CNC cutting tool selection guide to see how die maintenance affects your part quality. For tolerance limits on bends and hole positions, read the CNC machining tolerances guide — it explains what we can hold without extra cost.
Send us your drawing, a sample, or just a sketch with the conduit OD and material preference. We reply with a firm unit price, tooling cost (if any), and a delivery date within 12 business hours. Our team in Dongguan has been running stamping presses for 20 years, and we know what a fair price looks like for precision manufacturing.
