Our manufacturing process
At Amthor International, our goal is to create the highest quality tanks by using the best materials on the market and a human touch by our experienced welders and craftsmen. In addition to our tank manufacturing process, we have rigorous quality control checkpoints at every stage to ensure your tank is built to the highest standards and it will last for years to come.
This process starts by taking a flat sheet of metal, then it is rolled to created the side shell tank shape.
This is where the tank assembly begins. The side shell, top, floor, and interior of the tank are assembled and tacked together on a fixture model of a truck chassis.
The heads and baffles of your tank are either air blown or formed with a shear and break to the specific size of your tank.
This custom designed machinery is a large rotisserie robotic welder. This welder welds all longitudinal welds on the vessels and gives a tighter weld than any human can.
This is the final stage of tank production process where all components are assembled on the vessels.
This stage is where the tank is installed on the truck chassis of your choice. Piping and equipment is installed in this stage. Pumps are tested and calibrated.
Final stage of the manufacturing process. Blemishes and imperfections are cleaned and polished at this point.
Tank is shipped to customer.
