Industry × Material × Manufacturing Risk
Start with the engineering problem—not a generic process list
Use our technical guides to understand material behaviour, design risk and inspection requirements before you send a drawing. When the application is defined, JLYPT can review manufacturability and quote the part.
Inconel & Superalloys
Work hardening, concentrated cutting heat, notch wear and the practical differences between 718 and 625.
Read the guide →Titanium Machining
Heat control, tool engagement, thin features and surface-integrity considerations for demanding parts.
Explore titanium →Material Selection
Compare metals and engineering plastics by strength, corrosion, temperature, stability and machining risk.
Compare materials →Defect Prevention
Diagnose chatter, burrs, distortion, dimensional drift and surface defects before they affect a production batch.

Certification status, stated accurately
JLYPT lists ISO certifications separately from AS9100D- and IATF 16949-aligned process controls. Confirm the certificate and documentation scope for your programme before ordering.
Review certification scopeCertification Scope
See which systems are certified and which processes are aligned to industry requirements.
Inspection Process
Review CMM, material traceability and first-article documentation options.
Confirm Your Requirement
Send the drawing and specify the certificates, reports and critical dimensions your programme requires.
Industry

Your One-Stop CNC Machining Partner in China
JLY Precision Technology is a Chinese precision-manufacturing partner built for international B2B customers. We bring custom CNC machining, surface finishing and rapid prototyping under one roof, so you can take a part from first prototype to production without changing suppliers. With over 50 CNC machines, tolerances to ±0.005 mm, no minimum order quantity and 3-day prototype turnaround, we support engineers and buyers who need quality parts, fast, with clear communication in English.
Our core services span CNC machining (3-axis to 5-axis milling and turning), tight-tolerance precision manufacturing, micro-machining, surface finishing and anodizing, PVD coating, rapid 3D printing and urethane casting. Whatever stage your project is at, there is a service to match it.
100+ Materials, Machined to Spec
The right material drives cost, performance and lead time, so we machine the full range of production metals and engineering plastics and help you pick the best fit. Every material below links to an in-depth machining guide written by our engineers.
- Aluminium (6061, 7075) — light, fast-machining, anodises beautifully.
- Stainless steel (303, 304, 316, 17-4PH) — corrosion resistance and strength.
- Titanium (Grade 2, Grade 5) — best strength-to-weight, biocompatible.
- Brass & copper (C360, C110) — superb machinability and conductivity.
- Inconel & superalloys — strength and corrosion resistance above 700 °C.
- Engineering plastics (PEEK, Delrin/POM, nylon) — light, self-lubricating, chemical-resistant.
From Prototype to Production
Different stages call for different processes, and picking the wrong one quietly wastes money. We run every route in-house and match each part — and each stage of a program — to the most cost-effective method: 3D printing for early concepts, CNC machining for functional parts in the real material, and urethane casting for low-volume look-and-feel batches. Our guide on CNC vs 3D printing vs urethane casting lays out the full decision, and turning vs milling helps match process to part geometry.
Because we cover machining, finishing and prototyping together, you get engineer-to-engineer DFM feedback on every quote — practical suggestions that cut cost and lead time before you commit. See how much design choices move the price in our CNC cost reduction guide.
Precision, Quality & On-Time Delivery
Quality is measurable, not marketing. We hold tolerances to ±0.005 mm on critical features, verify them on calibrated CMM equipment, and back every order with material traceability and inspection documentation. Our processes are ISO 9001:2015 certified and AS9100-aligned for aerospace work, so parts meet the documentation and tolerance demands of regulated industries.
We serve aerospace, medical, robotics, UAV & drone, oil & gas, sensor, automotive and electronics customers worldwide. New to sourcing from China? Our guide on how to choose a China CNC supplier covers exactly what to verify. Ready to start? Upload your CAD files for a free quote and DFM review within 24 hours.
