Core Product Lines

Two shoulder bag lines, one accountable factory

From soft PU and microfiber fashion bags to heavyweight canvas programmes, both lines share the same sample room, stitching floor, QC system and export team. You can build a coordinated range without adding a second supplier.

Unlike trading companies that coordinate several shoulder bag manufacturers, both lines run in our own 5,000 m² facility. If you are evaluating a custom fashion shoulder bag supplier, ask for the sample room, the stitching standard and the QC record—not just a catalogue.

After-Sales

A written resolution and target date, handled directly by the same dedicated team—not a third-party agent.

Stitching Engineering

Stitching craftsmanship built to 240N and 400 impact cycles

For sourcing managers, “good stitching” is not a visual claim. It is a set of measurable parameters. These are the standards we build and inspect against on every shoulder bag order.

7–8SPI

Stitch density

≥240N

Main seam strength

400/250cycles

Jerk test

3–5stitches

Backstitch at start/end

Stitch density and seam appearance

7–8 stitches per inch (SPI), with balanced top and bottom thread tension. Seams run straight, stitch length stays uniform through curves and corners, and every seam is checked for skipped or missed stitches, loose thread, bottom-thread loosening, puckering and uneven tightening.

Reinforcement at stress points

Every seam starts and ends with 3–5 backstitches. Handles, shoulder-strap attachments and D-ring tabs are reinforced with computer bartacking and a standard X-box stitch. These are the points that fail first on a loaded shoulder bag, so they are specified—not left to operator discretion.

Seam strength and oscillation impact

Main seams must reach ≥240N across a 100 mm × 30 mm test area (QB/T 1333-2018). In the jerk test, double handles or straps survive 400 continuous impact cycles; single handles or straps survive 250. The pass criteria: no seam opening, no hardware loosening and no breakage at load points.

Seam strength is tested to QB/T 1333-2018. Reliability tests are repeated per batch and per quarter—not just at the first sample.

5-Stage Quality Control

Five defensive lines, from incoming material to outbound audit

Quality is controlled at the source, not sorted at the end. Every stage has a defined owner, checklist and rejection rule—so a defect is stopped before it becomes a batch.

Final quality control inspection of finished shoulder bags at Guangzhou Ruiwei Leather Co., Ltd.

01IQC

Incoming Quality Control

Stop defective materials before they reach the line.

Fabrics & leather: Same-lot colour consistency; no holes, scratches or stains; thickness variation ≤ ±0.1 mm; no odour.
Hardware: Plating appearance free from peeling, burrs and deformation; rack plating is specified for mirror-smooth hooks and buckles; buckles and zippers operate smoothly; riveting strength checked; neutral salt-spray ≥ 24 h with no corrosion. Material hierarchy: solid brass for luxury, zinc alloy die-casting for volume programmes; iron hardware is not accepted on exposed parts.
Threads & trims: Colour match within half a shade; specified breaking strength; rub fastness; no fuzzing or thread breakage.

02IPQC

In-Process Quality Control

Patrol the high-risk operations before defects become a batch.

Cutting: Critical panel dimension error ≤ ±0.5 mm; no visual defects on main panels; grain direction aligned to prevent distortion.
Sewing: Uniform stitch density; no skipped, missed or loose stitches; 3–5 backstitches at start/end; bartack and X-box reinforcement at handles and straps.
Hardware assembly: Installation position error ≤ 0.5 mm; rivets and screws tight; no scratches or plating loss after assembly.
Edge painting & gluing: Smooth edge paint with no bubbles, white edges or unevenness; no glue overflow, gaps or delamination.

03FQC

Final Quality Control (100% inspection)

Every finished bag is inspected—not sampled.

Overall appearance: Symmetrical shape with left/right height difference ≤ 1 mm; no colour variation within the bag; no stains, press marks or visible scratches.
Stitching detail: Straight seam lines and smooth curves; no loose threads or exposed thread ends inside; zero defects on main visual panels.
Functional hardware: Zippers and locks open and close smoothly; strap adjustment runs freely without slipping; pockets align and close securely.
Labels & dimensions: Length, width and height tolerance ≤ ±3 mm; brand and care labels positioned correctly.

04ORT

Reliability Testing

Periodic destructive sampling that proves the construction.

Seam strength: Main load-bearing seams ≥ 240N (QB/T 1333-2018).
Oscillation impact: Double handles 400 cycles / single strap 250 cycles; no seam opening or connector breakage.
Zipper life: 1,000 reciprocating cycles with no tooth loss or functional damage.
Hardware corrosion: Neutral salt-spray 24 h; no plating loss or corrosion.

05OQC

Outgoing Quality Control

Audit the lot before it leaves the factory.

AQL II sampling: Major 2.5 / Minor 4.0 / Critical 0. Packaging integrity, assortment accuracy, carton marks and appearance re-checked before loading.
Final release: No mispacking, shortage or packaging damage. Only lots that pass AQL II and document review are released; the QC record travels with the shipment.

AQL II sampling levels used at outgoing quality control.
Inspection level	Major	Minor	Critical
AQL II	2.5	4.0	0

Critical defects are not accepted at any AQL level. Lots that fail AQL II or document review are held for rework and re-inspection.

What is your MOQ for custom shoulder bags?

Standard MOQ is 100 pcs per style per colour for both PU/microfiber and canvas shoulder bags. This supports new-brand testing and repeat orders. Custom-dyed leathers, custom logo moulds or exclusive hardware tooling may require 500–1,000 pcs to cover setup costs.

Can you manufacture both women's fashion shoulder bags and canvas shoulder bags?

Yes. For buyers comparing canvas shoulder bag manufacturers, both lines run in the same 5,000 m² facility with one sample room, stitching floor and QC system. We produce PU and microfiber fashion shoulder bags in litchi, Saffiano, Nappa, Nubuck, tumbled and animal-embossed grains, plus heavyweight canvas shoulder bags with PU or leather trims.

How do you verify stitching strength, zipper life and hardware durability?

Main seams are tested to ≥240N on a 100 mm × 30 mm area. Handles and straps undergo 400-cycle jerk tests (double) or 250-cycle (single). Hardware is neutral salt-spray tested for 24 hours, and zippers are cycled 1,000 times. Production is inspected to AQL 2.5 major / 4.0 minor / 0 critical.

What are your sampling and bulk lead times?

Sampling is 3–7 days per round in our own sample room. Bulk production is 35 calendar days including material preparation; repeat orders are typically 25 days. Export documents, customs support and sea, air or express freight are handled by the same team.
