Your lock design deserves better than a generic catalog part. We machine door lock components exactly to your drawing, then verify every critical dimension before shipment. No surprises, no tolerance guessing.
At a glance: ±0.005 mm tolerance on request, 7–15 day lead time, no MOQ, ISO 9001:2015 certified factory.
We are a precision manufacturing facility in Dongguan, China, with 20 years of experience across CNC machining, metal stamping, springs, and heat sinks. One factory, four processes, one responsible partner.
Internal/external threads per ISO, ANSI, DIN standards
Batch Size
1 piece to 100,000+ pieces
Inspection
CMM reports, optical comparators, surface roughness testers, material certs
Lead Time
Prototypes 5–7 days; production 10–15 days after drawing approval
MOQ
No MOQ — start with a single prototype
Every batch gets a full dimensional report. If we machine it, we measure it. That is non-negotiable.
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality. Each part carries a unique batch number. We track material heat numbers, machine operator, tooling, and inspection results back to the source. If a problem appears in your assembly line, we trace it in minutes, not weeks.
2. Inspection report per batch. You do not have to trust our word. Every shipment includes a dimensional inspection report with actual measured values, not just pass/fail marks. Need a full CMM report? We provide it. Need material certificates? Included.
3. One factory for CNC + stamping + springs + heat sinks. Your door lock assembly likely needs more than just machined parts. Maybe a stamped latch plate, a torsion spring, or a heat sink for an electronic smart lock. We do all four in-house. One purchase order, one quality system, one shipping point. Fewer suppliers means fewer coordination headaches.
Where These Parts Are Used
CNC machined door lock parts are the hidden workhorses of security hardware. We machine components for:
Mortise locks — cylinders, tailpieces, face plates, and bolt housings requiring tight tolerances for smooth operation.
Electronic smart locks — fingerprint reader housings, motor mounts, and heat sinks for the control board. Precision here prevents misalignment and overheating.
Padlocks — shackle retainers, cylinder bodies, and key pins made from brass or stainless for corrosion resistance.
Commercial door hardware — lever handles, escutcheons, and strike plates machined from solid aluminum or zinc alloy for durability in high-traffic buildings.
Automotive door latches — pawls, rockers, and linkage arms that demand repeatable geometry over thousands of cycles.
These parts share one trait: they must fit and function without adjustment. Our machining tolerances make that possible.
Q: What is your MOQ?
A: No MOQ. We machine one prototype for your fit test, then scale to your production volume. Many suppliers refuse small batches; we built our workflow around them.
Q: How do you guarantee tolerance and quality?
A: We program every part from your 3D model, use in-process probing on the machine, and verify finished parts with CMM or optical measurement. The inspection report is included with every batch. If a dimension is out of spec, we rework or remake at no cost — but we rarely need to.
Q: What is your lead time for CNC machined door lock parts?
A: Prototypes ship in 5–7 days. Production runs take 10–15 days after you approve the first article. For urgent orders, we can split the batch and ship partial quantities to keep your line running.
Q: Do you provide material certificates?
A: Yes. Every material purchase comes with a mill certificate. We keep records for 5 years and attach copies to your shipment. For aerospace or medical-grade requirements, we source certified materials on request.
