Plasto Water Tanks

Plasto provides a wide range of overhead water tanks, underground tanks, horizontal water tanks and loft tanks of various layers and sizes. Every tank comes with a 10 years guarantee and the tanks are made from high quality food grade plastic keeping the water safe for drinking. Plasto water tanks are UV stabilized that protects the tank from harmful UV rays and doesn’t allow the sunlight to enter the tank. With this the water remains cool and algae free.

How are water tanks made?

Plasto water tank manufacturing process depends on various factors and varies on the type and size of the tank being produced. The process includes Raw material preparation, molding, finishing, quality control, packaging & shipping. Plasto water tank manufacturing includes two major processes. A) Roto-molding process B) Blow-molding process.

Roto-molding process also known as rotational molding process of manufacturing hollow water tanks. The process starts with adding powdered resins in a hollow mold, shaped like a tank. Future, the mold is heated and rotated on multiple axes to all the material to take the shape of the mold. The mold is distributed equally because of which a thick layer of the material forms inside the tank. Then the mold is kept aside to cool down. Once the material solidifies, the tank is removed from the mold. Further the water tank is finished and inspected by the quality engineer and sent further for screening, packaging and shipping. With the help of roto molding process tanks with complex shapes can be produced and of larger sizes where the tanks are used for industrial use or in waste water management. The process is relatively easy and efficient which allows a smooth manufacturing of water tanks.

Plasto water storage tanks made from roto-molding process are as follows:

1) 2 & 3 Layer Non-ISI water tank
2) 3 Layer underground tank
3) 2 Layer ISI tank
4) 4 Layer foam tank
5) Bio-Septic tank
6)  6 Layer Super Cool Double Foam Tank


Blow-molding process is another tank manufacturing process of making hollow plastic water tanks. In this process a tube of melted plastic, called a parison is placed in a mold and inflated by blowing the air inside the tube. Because of high air pressure, the melted material takes the shape of the mold. When the process completes the cycle time, the material is kept aside to cool down and solidify. Then the tank is taken out from the mold and processed for finishing. Once the finishing completes, the water tank is inspected by the quality engineer and then sent for screening, packaging and shipping.

Plasto water storage tanks made from blow-molding process are as follows:

1) 6 Layer vertical water tank
2) 6 Layer easy-clean water tank
3) 3 Layer ruf-tuf water tank
4) 2 Layer water tank
5) 3 Layer Loft tank
6) 8 Layer Tank
7) JET Pressure Tank
8) High Pressure Tank
