This is the Stamped Metal Grommets Eyelets Ferrules Collection from BQUQ, a 20-year precision manufacturing factory in Dongguan, China. We produce these stamped components with a dimensional tolerance of ±0.02 mm, a hardness range of 20–45 HRC, and a standard lead time of 7 days for prototypes. Every part is made on high-speed CNC stamping presses, and we ship worldwide with no MOQ.
Why Our 20-Ton High-Speed Presses Beat Progressive Die Shops
Most small stamping shops use older mechanical presses with high runout. We run 20-ton to 160-ton high-speed precision presses with a spindle runout under 0.005 mm. This means your grommets and ferrules have consistent wall thickness and a clean, burr-free edge — no secondary deburring needed. We hold a flatness of 0.05 mm on parts up to 100 mm diameter, and we can punch holes as small as 0.8 mm without tool deflection.
Materials and Hardness: From Soft Aluminum to Spring Steel
We stock over 15 coil and strip materials for this collection. For electrical eyelets, we use brass C2600, phosphor bronze C5210, and beryllium copper C17200 with hardness up to 45 HRC after heat treatment. For structural ferrules, we use stainless steel 301, 304, and 430, cold-rolled steel SPCC, and aluminum 5052. If you need a specific finish, we offer zinc plating, nickel plating, and passivation with a salt spray rating of 72 hours minimum.
How We Control Burr Height and Edge Quality on Thin-Wall Parts
Burr height is the #1 complaint with stamped grommets. Our tooling uses a custom clearance of 5–8% of material thickness, which keeps burr height below 0.03 mm. We also use a laser-optical burr measurement system on every production lot. For eyelets with a wall thickness of 0.15 mm, we guarantee no tearing or rollover at the edge. If you need a rolled rim or a flared end, we do that in the same die — no extra cost.
Inspection Before Every Shipment: CMM and Optical Projector
We do not ship blind. Every batch passes through our in-house QC lab, which includes a Zeiss CMM, an optical profile projector, and a surface roughness tester. We check outer diameter, inner diameter, concentricity, and wall thickness on a sampling plan of AQL 0.65. For critical parts, we can provide a full dimensional report with a CPK value above 1.33. Surface finish is held to Ra 0.8 µm on the OD and Ra 0.4 µm on the sealing face.
Tooling Costs and Die Life for Short and Long Runs
We build our own dies in-house, so tooling costs are 30% lower than outsourced dies. A simple grommet die costs $800–$1,500 and lasts 1–2 million strokes before maintenance. For the Stamped Metal Grommets Eyelets Ferrules Collection, we have over 40 existing tool sets that you can use for free — just change the material and we run it. If you need a custom shape, we deliver a new die in 15 days, and we offer free die storage for repeat orders.
Prototype to Production: Same Day Quote, 3-Day Samples
Send us a 2D drawing or a 3D STEP file. We quote within 12 hours, and we make prototype samples in 3 days using our in-house tool room. For production, we run 24/7 shifts with automated feed and stacking. Our typical lead time is 7 days for 100,000 pieces, and 15 days for 1 million pieces. We also offer a soft-tooling option for low-volume runs of 1,000–10,000 pieces, so you never pay for hard tooling during the design validation phase.
How to Choose Between a Grommet, an Eyelet, or a Ferrule
These three parts look similar but serve different functions. A grommet reinforces a hole in sheet metal or fabric — we make it with a rolled rim for a smooth edge. An eyelet is a tubular part used for lacing or electrical termination — we make it with a flared or curled end. A ferrule is a compression or crimp fitting — we make it with a hexagonal or knurled outer profile for grip. If you are unsure which one fits your assembly, send us your application and our engineers will recommend a design within one working day. For a deeper understanding of how these parts interact with cutting tools, read our CNC cutting tool selection guide. To confirm your dimensional callouts, review our CNC machining tolerances guide.
Surface Finishes and Plating Options for Corrosion Resistance
Bare metal is not always enough. We offer five standard finishes for this collection: bright nickel plating (2–5 µm), zinc plating with blue or yellow passivation (5–8 µm), tin plating for solderability (3–6 µm), black oxide for a matte look, and electropolishing for stainless steel. Salt spray resistance ranges from 48 hours for zinc to 500 hours for electropolished 304. All platings are RoHS and REACH compliant, and we can provide a material certificate with every lot.
Packaging and Logistics for Global Delivery
We pack in anti-static bags, then in corrugated cartons with EPE foam inserts to prevent deformation. For high-volume orders, we use bulk packing with 10,000 pieces per box. We ship from Shenzhen port via DHL, FedEx, or sea freight. For urgent orders, we can air-ship samples within 24 hours to any major city in the US, EU, or Southeast Asia. Our export documentation includes a commercial invoice, packing list, and certificate of origin — all handled in-house.
What is the minimum order quantity for this collection?
There is no MOQ — you can order 100 pieces for a prototype test or 1 million pieces for production, and the per-unit price adjusts accordingly.
Can you customize the shape, material, or finish of a standard grommet?
Yes, we can modify any standard tool or build a new die for your custom shape, material, or finish, with a 15-day tooling lead time and free die storage.
How do you ensure quality on high-volume stamping runs?
We use in-process SPC with automated laser measurement every 500 pieces, plus a final AQL 0.65 inspection on a CMM and optical projector before shipment.
What is the lead time for a custom stamped metal grommet or ferrule?
Prototype samples are ready in 3 days, production orders ship in 7–15 days depending on quantity, and all quotes are returned within 12 hours.
