Rotomoulding Facts

Here are some key facts about rotomoulding products (also known as rotational moulding products):

1. Manufacturing Process

• Rotomoulding involves placing powdered plastic into a hollow mold, which is then heated and rotated.

• The plastic sticks to the heated mould and melts for form a seamless, hollow product.

2. Material Used

• The most common material is polyethylene (PE) due to its flexibility and durability.

• Other materials include polypropylene (PP), PVC, and nylon, though less frequently.

3. Durability

• Products are highly durable and impact-resistant, making them suitable for rugged applications like water tanks, fuel tanks, and playground equipment.

4. Seamless and Leak-Proof

• The process creates seamless one-piece items, which makes them leak-proof and ideal for liquid storage.

5. Design Flexibility

• Complex shapes, contours, and double-walled constructions are possible.

• Embossed logos, inserts, and threads can be added during moulding.

6. Cost-Effective for Small Runs

• Tooling costs are lower than other plastic molding processes like injection molding.

• Best suited for low to medium production volumes.

7. Applications

• Common products: water tanks, kayaks, coolers, bins, traffic barriers, and playground equipment.

8. Environmental Impact

• Rotomoulded products usually haver a long design life which can be greater than 20 years.

• Rotomoulded products are usually recyclable and can be made from recycled plastics.

• The process produces minimal waste.
