Factory & Manufacturing
12,000 m2 of integrated manufacturing — from raw material to finished boat
Explore Our Manufacturing Capabilities
Production Capacity
12,000 m² facility producing 15,000+ boats/yr across SUP (8,000+), RIB (2,000+), inflatable dinghy (5,000+), and safety equipment lines. 200+ workers, 2 shifts.
Quality Lab & Testing
Independent QC lab with 4 testing stages: raw material inspection (tensile, tear, UV), 48h pressure hold at 1.25x rated pressure, seam peel testing, and load/balance verification on every boat.
OEM/ODM Capability
End-to-end OEM/ODM services: custom mould design, private-label packaging, custom tube colors, deck graphics (digital & screen printing), Hypalon upgrade option, and drop-ship logistics.
Manufacturing Workshops
PVC Cutting & Material Preparation
Automatic CNC cutting machines process PVC, Hypalon, and drop-stitch fabrics with sub-millimetre precision. Computer-optimised nesting minimises material waste and ensures every panel meets its dimensional specification before welding.
Tube Welding & Heat Sealing
Dedicated welding workshop with heat sealing machines and RF dielectric presses. Hot-air heat sealers bond and fuse PVC tube chambers, while RF welds produce high-strength airtight seams that exceed requirements.
RIB Hull Production — Fiberglass
RIB boat hulls are produced using hand-lay-up fiberglass moulding with polyester and vinylester resin systems. Each layer is hand-rolled and vacuum-bagged for consistent quality. Gelcoat spray booth provides a high-gloss, UV-resistant marine finish.
SUP Printing & Decoration
SUP boards are decorated using digital printing for full-colour graphics and screen printing for logos and repeating patterns. Digital printers produce photo-quality deck designs, while screen printing delivers durable, vivid brand marks.
Final Assembly & Rigging
Assembly line where fiberglass hulls and PVC tubes are mated, engines are mounted, steering and controls are connected, and electrical systems are wired. Each boat follows a 100-point assembly checklist signed off by the team lead.
Quality Testing & Inspection
Every completed boat undergoes mandatory air-retention testing, seam peel verification, and a full systems check before shipping. Our quality lab operates independently from production and reports directly to management.
Key Manufacturing Equipment
Testing & Quality Assurance Process
Every boat undergoes mandatory testing before shipping. Our quality lab operates independently from production and reports directly to management.
Raw Material Inspection
PVC, Hypalon, and drop-stitch fabrics undergo tensile testing (), tear propagation, and UV resistance verification before any batch enters production.
48-Hour Air Retention Test
Every tube chamber is inflated to 125% of rated pressure and held for 48 hours. Pressure drop below 5% triggers automatic rejection and seam re-inspection.
Load & Balance Testing
Completed boats are loaded to maximum rated capacity and tested for stability, freeboard, and handling. Each vessel is water-tested before final inspection.
From Material to Finished Boat
Every boat passes through 6 production stages with QC checkpoints at every step. No shortcuts, no skipped inspections.
Material Receiving & Incoming QC
All incoming materials are logged by batch/lot number in our ERP system. PVC fabric rolls, drop-stitch cores, valves, adhesives, and hardware are quarantined until QC sign-off.
Tensile strength (ASTM D751), tear resistance (ISO 4674), thickness gauge, adhesive viscosity, visual defect scan
100% of batches tested. Reject if tensile < 90% of spec, tear < spec min, or any visual defect
Responsibility: Incoming QC team (3 inspectors)
CNC Cutting & Material Prep
Computer-optimized nesting lays out panels on PVC stock to minimize waste. Automatic CNC cutting machines maintain 0.1 mm positional accuracy.
Dimensional check against CAD DXF files, edge quality inspection, panel count verification
Every 20th panel measured. Tolerance ±0.5 mm. Reject batch if >2% out of tolerance
Responsibility: Cutting workshop lead
Welding & Drop-Stitch Bonding
Drop-stitch cores are bonded to outer PVC laminates using heat lamination. Tube chambers are RF-welded or hot-air welded. Rail bands are triple-layer fusion bonded.
Peel test every 50 units (ASTM D751), weld width measurement, hot-air temperature log review, visual seam inspection under backlight
Peel strength min 8 N/cm. Weld width tolerance ±1 mm. Any visible channeling = reject
Responsibility: Welding QC (2 inspectors per shift)
Assembly & Rigging
Boats move to final assembly where all components are mated: hull + tubes, valves installed, D-rings, handles, fin boxes, and carry bag fitting. Each unit follows a 100-point assembly checklist.
100-point checklist sign-off per unit, valve function test (10 open/close cycles), hardware torque verification, visual inspection
Zero-defect policy on safety-critical items (valves, D-rings, handles). Minor cosmetic: AQL 2.5 (ISO 2859)
Responsibility: Assembly team lead + line QC
Pressure Testing & Quality Hold
Every chamber is inflated to 1.25× rated pressure (typically 20–25 PSI) and held for 24–48 hours. Pressure sensors log continuously. Chambers exceeding 5% pressure drop are rejected and sent for seam re-inspection.
24h pressure hold log, sensor calibration verified daily, temperature-compensated pressure reading, seam re-test after repair
Max 5% pressure drop over 24h at stable temp. Any chamber exceeding this = 100% re-test of entire production batch
Responsibility: Quality lab (independent of production, reports to management)
Final Inspection & Packing
Final visual and functional inspection. Surface defects, color consistency, label/BIN verification, packaging integrity, and accessory completeness. Units are vacuum-packed, boxed, and palletized for container loading.
Full visual inspection, accessory checklist per SKU, packaging drop test (1 m, random sample), label/bar code scan verification
AQL 2.5 for major defects, AQL 4.0 for minor. Zero tolerance on safety defects. 100% of units visually inspected
Responsibility: Final QC team (4 inspectors) + Packing team lead
Workforce & Departments
Engineers across R&D, mold design, materials lab, and production engineering. Average 7+ years in inflatable manufacturing.
2 shifts/day (07:00–15:30, 15:30–00:00). Optional night shift for urgent orders.
Monthly QC training, quarterly safety drills, annual skills assessment. New hires complete 40-hour induction before working on production line.
Material Tracking & Batch Control
Every batch of raw material is assigned a unique lot number in our ERP system. From arrival through production to the finished product, each boat's bill of materials links back to the original supplier batch. This enables full upstream traceability for any quality or compliance inquiry.
System: Custom ERP (Qingdao Vatrad Group internal system) + physical batch tags on each work order
Coverage: 100% of production materials — PVC, Hypalon, drop-stitch fabric, adhesives, valves, hardware, packaging
Records retained: 10 years (per CE 2013/53/EU requirement)
| Material | Source | Certification |
|---|---|---|
| Marine-grade PVC | Chinese and Korean suppliers | ISO 9001, REACH, RoHS |
| Hypalon (CSM) | Japanese supplier | ISO 9001, REACH |
| Drop-stitch fabric | In-house weaving + external partner | Internal QC + supplier ISO 9001 |
| Valves & Hardware | Chinese OEM suppliers | ISO 9001, material certs per batch |
