What is rotational Molding?

Rotational molding (also known as rotomolding) is a process which uses low cost tooling and engineered resins to produce seamless, durable, hollow plastic products.

The rotomolding process produces parts with uniform wall thickness, strong, virtually stress free outside corners, and a seamless design, making it a popular choice for parts that need to be inherently lightweight yet sturdy.

The process’ versatility also allows design and production flexibility, allowing you to produce complex shapes with undercuts, ribbing structures, textures, colors, molded-in threaded inserts, colored graphics, and expanded polyethylene, double wall sections.

Process

Advantages

  • Design Flexibility: Rotational molding allows for complex shapes and intricate designs. 
  • Cost-Effectiveness: Compared to other molding processes, rotomolding often requires simpler, cheaper molds, making it an economical option for low to medium production runs.
  • Uniform Thickness & Seamless Construction: The uniform wall thickness and seamless design inherent to rotomolding improves the structural integrity and durability of the final product and reduces the risk of cracks, leaks, or weak points.
  • Customization: Rotomolding enables easy customization of design, color, graphics, etc.
  • Suitable for Large Parts: Rotomolding is capable of producing larger parts than other methods.
  • Materials: Compatible with a wide range of thermoplastic materials, allowing manufacturers to choose materials that suit their specific needs, such as UV resistance, chemical resistance or food-grade properties.
  • Shorter Lead Times: The simplicity of the rotational molding process makes it ideal for short runs and rush deliveries.
  • Eco-Friendly: Rotomolding produces little to no waste as excess resin can be reused, resulting in a lower environmental impact.
