Production based on several methods of materials processing

A range of specialised plastics processing and metallurgy production methods enable us to provide you with optimum solutions. The combination of materials and their processing makes it possible to manufacture projects that incorporate structures, welded frames combined with rotomoulded, thermoformed or polyurethane parts.

Our foaming facilities (PU, PE, PSE…) also enable us to offer specific buoyancy solutions and to guarantee insubmersibility.

 

Rotomoulding

Rotomoulding is ideally suited to the demands of boating.

The characteristics of rotomoulded parts:
→ Resistance to ageing
→ Perfect Sealing
→ Life span
→ Reaction to shocks
→ Respectful of the environment
→ Lightweight
→ Rigidity
→ Ease of maintenance
→ UV resistance

GMI’s large capacity industrial facilities are ideally suited to small or big series production.

Examples of rotomoulded parts used in sports and boating:

Monohull boats
Rotomoulded floats: Marker buoys, mooring buoys
Obstacles for water parks: Leisure equipment and water slides
Pedalos, sliders: Canoes, kayaks
Floating platforms: Pontoons and accessories (life buoy housing units, fenders)
Swimming pool
Components Tanks for all types of fluid
