Manufacturing
Machined, Assembled, and Run-Off Tested Before It Leaves Wenzhou.
Yaoshg does not outsource its core platforms. Flexographic presses, converting modules, and bag making lines are built on one campus—by teams who repeat the same architectures every week and sign off every machine on the test floor before crating.

Manufacturing Excellence overview
Campus Overview
35,000 Square Meters From CNC Cut to Export Crate
Converters judge manufacturers by Monday-morning register—not a brochure speed figure. Our Rui'an campus combines machining, three dedicated assembly halls, run-off bays, and export staging under one roof.
Project managers, fitters, and electricians share the same floor. Incoming components pass inspection gates before assembly. Finished machines move from test bay to crating without leaving the site.
Our company storyThree Assembly Halls · One Campus
Each product family has its own hall, jigs, and acceptance habits.
Image placeholderFlexible packaging printing production line
Stack, CI, and in-line flexographic presses assembled with overhead capacity for cylinder modules and drying tunnels. The stack, CI, sleeve gear-driven CI, gearless servo CI, and woven bag flexographic printing systems series follow repeatable workflows within each architecture family.
Every press leaves with documented anilox handling, tension setup, and color-deck alignment records.
- Registration calibration before hall exit
- Shared jigs within stack, CI, and in-line families
- Series specs on product pages—not duplicated here
Image placeholderSlitting and rewinding converting equipment
Servo turret slitters, duplex rewinders, rotary die-cutters, and dry laminators with tension calibration on dedicated jigs. Knife mounting and nip checks are stage-gated before run-off.
- Tension jigs for turret and duplex slitters
- Edge quality as an acceptance criterion
- Downstream handoff logic reviewed with print scope
Image placeholderPlastic bag making production
Plastic, courier, non-woven, and paper bag lines run on sealing test stands before crating. Dimensions, handles, stack quality, and waste rates checked against the customer brief.
- Sealing trials on PE, HDPE, and coated paper
- Feeder tuning and sealing bar profiling
- Optional inline print integration trials

What We Build Here
Four Production Lines · One Manufacturing Standard
In-house assembly for core platforms—not contract manufacturing for anonymous brands.

Post-Press
Slitting, Laminating & Die-Cutting
Converting modules built with tension discipline and edge quality as acceptance criteria.
- Turret slitters · Laminators · Rotary die-cutters

Bag Making
Plastic, Paper & Non-Woven Bag Lines
Sealing test stands validate cycle stability before crating for export fulfillment and retail programs.
- Courier mailers · T-shirt bags · Square-bottom paper bags
Production Pipeline
Six Stages From Purchase Order to Export-Ready
Documented path for single presses and multi-machine lines alike.
- Engineering release & hall assignment · BOM, suppliers, flexo / converting / bag routing
- Fabrication & incoming inspection · CNC, welding, component sampling
- Mechanical assembly & stage sign-off · torque records, alignment sheets
- Electrical integration & safety validation · panel mount, PLC/HMI, interlocks
- Run-off testing & factory acceptance · FAT checklists, optional customer witness
- Finishing, crating & dispatch · serial records travel with the machine
