Production of the products in the closed form. First – just as in hand method – we apply gelcoat (manually or by SPRAYING)
Next, we stack structural layers in the mold (glass mats, fabrics, synthetic mats, mats in the form of a sandwich, Coremat, rovicore, etc.) as well as any strengthening and adaptations.
Once that’s done the mold is closed, it can be closed with a specially prepared membrane laminate PWS (punch) or the membrane made of plastic bag or silicone.
In any case, it is critical to ensure tightness of the mold. Once the mold is closed vacuum is being generated and then the mold is filled with a suitable resin through a specially made channels or openings. Resin injection and filtering of the carrier material happens through created underpressure.
