GMI - Leader in the design and production of rotomoulded plastic tanks for the vehicle industry

EXPERTS IN ROTOMOULDED TANKS

The GROUPE MAILLARD INDUSTRIE designs and manufactures specific tanks and/or visible tanks in rotomoulded plastic for any fluid.

These tanks are particular suited to the special vehicles market: HGVs, utility vehicles, trains, worksite machinery, 2-wheeled vehicles, camper vans, ambulances, armoured personnel carrier…

Experience in the rotomoulding techniques makes it possible to create lightweight tanks with a design adapted to the constraints of each vehicle.

Design

Following analysis of your specifications data, our design office studies the design and geometry of the tank depending on the size and constraints of the vehicle.

Rotomoulding technology offers real benefits in terms of optimising the volumes available in the vehicle.

From the design stage onwards, and depending on requirements, our software can carry out static and dynamic resistance calculations (strength of the materials, simulation and movement of fluids, shocks…). This expertise ensures that you get the very best technico-economic solution.

Use and type of fluid contained

Depending on the use and type of fluid in question, tanks can be made in POLYETHYLENE (HDPE, LDPE, MDPE, PER…), POLYPROPYLENE (PP), POLYAMIDE (PA6, PA6-6, PA11, PA12)…

List of main fluids:
WATER, DIESEL, PETROL, LPG, UREA, COOLANT, HYDRAULIC OIL, WINDSCREEN WASHER, SPECIAL FLUIDS, BRAKE FLUID, WASTE WATER, CHEMICAL AGENTS, HELIUM, HYDROGEN, LIQUID FERTILIZER

Industrialisation – manufacture

The tools department manages the manufacture, validation and maintenance of the moulds independently to guarantees the flexibility and responsiveness of our production units.

Our production lines are able to manufacture complex tanks with inserts, accessories and screen printing from 0.5 to more than 30,000 litres.
Extensive experience in automated plastic welding means that we can create technical and aesthetic assemblies whilst guaranteeing the sealing of the tank, whatever its geometry.
Strict leakage tests are carried out on the production line and adapted to the constraints of each project.

Certification / Standard

GMI’s experience enables us to support customers in the partial or complete management of tank certification in France and internationally: TUV / UTAC / AIDIMA.

The application of PPAP procedures guarantees the reliability of the design, manufacturing and means implemented to meet customer requirements

 

Assembly and delivery

Delivery of complete functions ready to be assembled on a vehicle. (Plugging, filter, piping, pump, drain valve, gauge….). Our ERP operating system and our logistics unit allow us to manage the supply of parts and accessories supplied by our customers or sourced by our procurement department.
Tanks stocks can be managed internally using Fifo and/or JIT methods.

The benefits of a rotomoulded plastic tank

Impermeability

because the sides of the tanks are made without welding or gluing

Resistance

because they are manufactured without the use of tension in comparison with other plastics processing technologies

Lightweight

because the density is less than a metal tank

Anti-corrosion

because the material is inert and is not subject to oxidation

Recyclable

because the material is 100% recyclable
