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
Frames, sheet-metal panels and machined parts such as forming collars and sealing jaws are made in our own workshops; electrical, pneumatic and drive components come from established brands, shown further down this page.
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
Forming tubes, sealing jaws, and precision fittings are machined in-house — the 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
Test run across two working days on your bag sizes and formats. 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.
Planning your own acceptance criteria before the balance is released? Our complete Packaging Machine Factory Acceptance Test checklist covers what to specify, what to measure, and which documents to collect before crating. See how this played out in our customer case studies.
Brand-Name Components
We don't cut corners on components. Core electrical, pneumatic, and sensing parts come from established brands — the main ones are shown below.
Siemens
HMI touchscreen (SMART 700) + PLC controller — the control core on our premade-bag machines.
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. Every export shipment is professionally packed in fumigation-free wooden crates, loaded by our team, and shipped from Shenzhen or Shantou port.
