We use 5-axis CNC machines for complex undercuts and spring-loaded hook mechanisms. For high-volume runs, we combine CNC machining with secondary stamping to reduce cost per piece. All parts are deburred and tumbled before final inspection.
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality.
Every batch gets a unique lot number. We record machine parameters, tool wear, and operator ID for each run. If a defect appears in the field, we trace it back to the exact shift and machine. You get a full traceability report with every shipment.
2. Inspection report per batch.
We do not ship without data. Each batch includes a dimensional report with CMM measurements, surface roughness readings, and material hardness verification. You can check the numbers against your drawing before we pack the parts. No surprises at your incoming QC.
3. One factory for CNC + stamping + spring + heat sink.
Your clasp may need a stamped spring plate, a coiled torque spring, or a heat-treated pin. We do all of it under one roof. No multi-vendor coordination, no tolerance stack-up between suppliers. Send us the assembly drawing—we handle the rest.
Where These Parts Are Used
CNC machined clasps and hooks are not just for necklaces. Real applications include:
Luxury watch bracelets—folding clasps with micro-adjustable links, machined from solid 316L.
Medical alert jewelry—titanium hooks that must resist corrosion and repeated autoclaving.
High-end handbag hardware—rotating hooks and magnetic clasps with tight press-fit tolerances.
Industrial lanyards—safety hooks with spring-loaded gates, tested to 50,000 cycles.
Custom orthodontic retainers—small precision hooks machined from biocompatible titanium.
In every case, the part must open and close smoothly thousands of times. That requires exact geometry, not just a pretty surface. Our CNC process holds the critical angles and radii that make the mechanism feel solid.
Q: What is your MOQ?
A: No MOQ. We machine a single prototype for your evaluation, then scale to any quantity. Tooling cost is amortized only if you order over 500 pieces.
Q: How do you guarantee tolerance and quality?
A: We use a 3D model for programming, not a 2D sketch. First article is inspected 100% on a CMM. Production batches are sampled at AQL 0.65, and we send the full inspection report with each shipment.
Q: What is the lead time for a custom clasp?
A: Prototype in 7–10 working days after drawing approval. Production orders ship in 15–20 days. Urgent orders can be expedited for a 30% surcharge.
Q: Can you provide material certificates?
A: Yes. We supply mill test certificates for all raw material, including chemical composition and mechanical properties. For gold-plated parts, we provide plating thickness reports.
