From Inquiry to Stable Production — How We Deliver Your Machine
From bag-type analysis and custom configuration to factory acceptance testing (FAT), export packing, and long-term support, Lingfeng follows a proven workflow built on 30+ years of experience — so your plastic bag making machine arrives ready to run and keeps running.
Requirement & Bag-Type Analysis
Tell us your bag type (T-shirt, flat, bags-on-roll, side-seal), film material (PE / PP / PET / PLA), width, target speed, and output. Our engineers recommend the right machine configuration around your production goals.
Custom Configuration & Build
Welding, painting, high-precision parts machining, hand assembly, and debugging. We share clear photo/video updates at key milestones so you can track build quality and the timeline with confidence.
Material Testing & Trial Run
We run the machine under real conditions using your film (or an approved equivalent) and verify key outputs — seal strength, flatness, cutting accuracy, and 10-micron delivery precision — reducing risk before shipment.
FAT Acceptance — Video or On-Site
Run a Factory Acceptance Test via live video call or in-person visit. We demonstrate stable running performance, safety checks, and output quality. We ship only after your approval.
Export Packing & Safe Shipment
Your machine gets anti-rust treatment and secure standard export crating. We focus on shock resistance and long-distance ocean-freight protection so it arrives ready for installation.
Installation, Training & Support
Commissioning guidance, operator training, and a 20-year-experienced after-sales team online. With a 1-year warranty, software upgrades, and overseas on-site engineer service, we help you reach stable production faster.
