1. Economic compare to other process like injection moulding and blow moulding.
2. Less expensive moulds.
3. Different parts can be moulded at the same time.
4. Very large hollow products can be made.
5. Low maintenance.
6. Low scrape in production
7. Uniform wall thickness is possible.
8. Stress free parts

The roto moulding industry started with manufacture of water tank and such kind of products which were not possible in other moulding process like injection and blow moulding. But now, its products are taking place of injection moulding and blow moulding products.

Therefore, the applications and area of roto moulding is increasing. The roto moulding is making way in following industry.

1. House holds: Water Tank (vertical and horizontal), Loft tank etc.
2. Material Handling: Crates, Pallets, Dust bins, textile trolley etc.
3. Automotive: Fuel Tank, Mud guard etc.
4. Road Safety: Road barrier, Traffic Cone, Road Divider, Traffic Bollard etc.
5. Packaging: Insulated ice Box/cooler box, bins etc.
6. Playing Equipment: Ladder and Slide, Rocker, Garden chair, Toys etc.
7. Agriculture and Construction: Septic Tank, Horse Trough etc.
8. Special Application: Toilet Booth, Telephone booth, Dummy et

LLDPE (Linear Low Density Poly Ethylene) is the most widely used raw material for roto moulding process. The density used for this material is between 0.930 to 0.936. Vinyls (both liquid and powder form) are the second most widely used raw material for roto moulding.

Rotational Moulding is a thermoplastic processing method for producing hollow parts and products from the most simple to the very complex.

The rotational moulding process consist of 6 steps-

1. A predetermined amount of plastic raw material is deposited in one half of a mould.
2. The mould is closed.
3. The mould is rotated bi-axially and heated inside an oven of roto moulding machine.
4. The plastic melts and forms a coating over the inside surface of the mould.
5. After a proper heating in a fixed time, mould is removed from the oven and cooled.
6. The mould is opened and the hollow part/product is removed. It is the final and finished product ready
to send in the market
