Why Choose Linqi
Where others stop, Linqi begins — We specialize in the toughest welding challenges
Servo Precision ±0.005mm
Self-developed Dream S servo drive system with ±0.005mm repeat positioning accuracy. Supports 6 intelligent welding modes: time, energy, distance, power, frequency, and phase. 10-inch industrial touchscreen displays real-time weld curves, pressure waveforms and energy distribution — every weld fully traceable, analyzable and exportable
Tough Jobs Specialist
We solve industry pain points: PEEK/PPS with high melting point and poor flow? Our proprietary gradient heating achieves 95% base material strength. PP surface damage, dents or burns after ultrasonic welding? Our servo precision pressure control + staged ultrasonic energy output delivers 100% zero surface damage on PP welding. Your toughest challenge is our specialty
Free Sample Testing
Free sample welding before purchase — see results firsthand. Dedicated 1-on-1 engineer support covering melting point analysis, horn frequency matching, energy director design, and batch process parameter locking. Sample reports include weld strength, air-tightness, and appearance ratings — zero-risk decision making
15-Day Free Trial
Not sure about the equipment? Try 15 days first. Delivered and installed on-site, our engineers stay until stable qualified output is achieved. If yield rate doesn't meet our commitment during trial? Unconditional return with all shipping covered. Over 200 companies converted from trial to long-term customers — 96% trial-to-purchase rate
From Inquiry to Production, Worry-Free
Standardized service process with dedicated support at every step
Process Assessment
Submit drawings or samples. Engineers evaluate material properties (melting point, MFI, glass fiber ratio), weld joint design (energy director geometry, weld line placement), and cycle time — feasibility report within 1 hour
Solution Design
Complete process package based on test data: horn frequency & amplitude matching calculations, custom fixture 3D modeling, weld parameter window optimization (energy/pressure/time optimal range) for batch consistency
Weld Verification
Free sample welding with professional test report: tensile testing (weld strength ≥85% of base material), air-tightness (IP67/IP68), cross-section analysis (fusion layer thickness & uniformity) — data-driven process validation
Manufacturing
72-hour continuous full-load stress test after assembly. Each unit verified for resonance frequency deviation (≤±0.5%) and weld repeatability (CPK≥1.33) before shipment
On-Site Launch
Engineers on-site for installation, line integration and first-article tuning. SOP creation, operator training and certification, sign-off only after 200+ consecutive parts meet quality targets
Full Lifecycle Support
1-year full warranty, lifetime vibration system maintenance. Connected equipment enables remote parameter diagnostics and OTA upgrades, 48-hour response with regional spare parts depots to minimize downtime
