Roto Molding

Polymer rotomolding, or rotational molding, is a manufacturing process used to create hollow plastic products. It involves heating a plastic material inside a mold while rotating it biaxially (around two perpendicular axes). This ensures the material coats the mold’s interior evenly, forming the desired shape as it cools and solidifies.

Advantages:

• Design Flexibility: Suitable for complex, large, and seamless shapes.
• Cost-Effective: Lower tooling costs compared to other methods.
• Durability: Produces strong, stress-free parts with uniform wall thickness.
• Material Efficiency: Minimal waste as excess material can be reused.

Applications:

• Industrial: Tanks, containers, and housings.
• Consumer Goods: Toys, furniture, and kayaks.
• Automotive: Fuel tanks and ducting.
• Medical: Equipment housings and containers.

Materials:

Commonly used materials include polyethylene (HDPE, LDPE, LLDPE)
