Manufacturing Process

Every incoming batch of PVC fabric, fiberglass mat, resin, and hardware is inspected against specification. Fabric samples are tested for tensile strength, thickness uniformity, and UV resistance before release to production. Non-conforming materials are quarantined and returned.

Approved fabrics are laid on the automatic CNC cutting machine and cut with sub-millimetre accuracy. Computer-optimised nesting arranges panels to minimise waste —typically below 5%. Cut panels are labelled by boat model and chamber, then bundled for transfer to the welding workshop.

Panels are tacked and bonded using heat sealing machines with hot-air welding at controlled temperatures of 200–300 °C. Main seams are reinforced with RF dielectric welding for airtight, high-strength joints. Completed chambers are inflated to 1.5× working pressure for 30-minute air-retention validation.

SUP board drop-stitch cores are bonded to outer PVC laminates using heat lamination. Thousands of internal polyester threads connect top and bottom layers, creating a rigid structure at 12-15 PSI. Rail bands are triple-layer fusion bonded for edge strength.

SUP board deck graphics are applied using digital printing for full-colour photo-quality designs, and screen printing for durable logos and repeating patterns. Prints are cured and sealed for UV and abrasion resistance.

Valves, D-rings, handles, fin boxes, and deck pads are installed on the assembly line. Each board follows a 100-point assembly checklist with mandatory sign-off at each stage.

Every completed board undergoes mandatory quality gate: chamber air-retention test, hardware function check, fastener torque verification, and cosmetic inspection. Custom and prototype builds also receive in-water trials covering stability and handling.

Boards are deflated, folded per procedure, packed in heavy-duty woven bags or retail boxes, and loaded for shipment. Each package is labelled with model, serial number, and destination. We coordinate with freight forwarders for FCL and LCL container shipments worldwide.
