FAT Before Ship
A Purpose-Built Packaging Machine Factory
Located in Shantou, Guangdong — the birthplace of China's packaging machinery industry — our facility houses everything from administrative offices and engineering labs to precision machining workshops and final assembly lines.
From Raw Steel to Precision Components
Every critical part is manufactured in-house. Our sheet metal workshop and CNC machining center produce frames, forming collars, sealing jaws, and structural components to tight tolerances — eliminating reliance on outsourced parts.
Sheet Metal & Laser Cutting
Fiber laser cutters process stainless steel 304 and carbon steel plates into frames, panels, and structural components. All cutting, bending, and welding happens on-site for full dimensional control.
CNC Precision Machining
VMC 850 vertical machining centers mill forming tubes, sealing jaws, and precision fittings. Tolerances are held to ±0.02 mm for parts that directly affect bag-forming accuracy and seal quality.
Six Dedicated Production Lines
Our production floor runs parallel assembly lines for premade bag, collar type, vertical FFS, and pillow packing machines. Each line is staffed by experienced technicians who handle mechanical assembly, electrical wiring, PLC programming, and initial commissioning.
Every Machine Tested Before It Ships
Our 4-person QC team runs every machine through a structured Factory Acceptance Test (FAT) before crating. No machine leaves without passing — period.
Incoming Inspection
All purchased components — motors, PLCs, pneumatic valves, sensors — verified against specs before entering the assembly line.
In-Process Check
Dimensional checks during machining and sub-assembly. Wiring harnesses tested for continuity and insulation resistance before panel close-up.
Full Machine FAT
72-hour continuous run test with actual packaging film and product material. Speed, seal quality, weight accuracy, and rejection rate all logged.
Final Sign-Off
QC report, test video, and photos sent to you for approval before crating. Machine packed in fumigation-free wooden crate for export.
International Brand Components Only
We don't cut corners on components. Every electrical, pneumatic, and sensing system uses internationally recognized brands — the same parts you'd find in European and Japanese machines.
Siemens
HMI touchscreen (SMART 700) + PLC controller (S7-200). Core brain of every machine.
Schneider Electric
Circuit breakers (Easy9 series). Overload and short-circuit protection for the entire electrical system.
Omron
Rotary encoders (E6B2-CWZ6C) for precise film tracking. Ensures accurate bag length every cycle.
SMC
Pneumatic guide cylinders for bag opening, clamping, and sealing actuation. Japan-made precision.
AirTAC
Solenoid valves (4V210 series) controlling all pneumatic actions — fast response, long service life.
Panasonic / Servo
Servo motors for high-speed and high-precision applications. Used in pillow machines and candy packaging lines.
CE Certified. Shipped to 80+ Countries.
Our core machine lines hold valid CE certificates issued by TÜV-affiliated bodies. Every export shipment is professionally packed in fumigation-free wooden crates, loaded by our team, and shipped from Shenzhen or Shantou port.
Valid: April 2023 – April 2028

Professional Crating & Loading
Each machine is wrapped in protective film, bolted to a wooden pallet, and sealed in a fumigation-free plywood crate. Our team handles forklift loading to ensure damage-free container stuffing.
International Customer Network
Buyers from the Middle East, Southeast Asia, Africa, South America, and Europe visit our factory regularly to inspect machines before shipping. We welcome factory audits and arrange hotel transfers from Jieyang Airport.
