Rotational molding is also known as rotational molding (Rotational Moulding), it is the amount of powdered resin loaded into the cold state of the mold, driven by the rotational molding machine around the two mutually perpendicular axis of slow rotation and rotation, while heating the mold with an additional source of heat, so that the powdered resin melted and with the help of its own gravity evenly coated on the surface of the entire cavity of the mold, and finally after cooling! Finally, the hollow products are obtained after cooling and demolding.

CNC Turning FAQs

1.Q: How do I know if rotational molding is the right process for my product?

A: The geometry of the part, the amount of parts needed, your tooling budget and the application the part is being used for will all influence your decision to rotational mold the part.

2.Q: What types of products are typically made through rotational molding?

A: This includes shells and containers of all sizes, playground equipment that needs to be durable and safe, as well as automotive parts that require precise specifications, and custom-designed outdoor furniture.

3.Q: What materials should I use for my project?

A: Different materials are used in different industries. If you have not selected a material for your application, we can provide assistance and guidance. Usually production samples are provided for confirmation, but final customer approval is required before mass production.

4.Q: Do you offer extended molding services such as assembly, packaging or decorating?

A: We can provide some standard packaging services. If you need to provide customized packaging, decoration, or assembly services, please contact us.

5.Q: How long does it take to build an rotational mold?

A: 4-8 weeks on average, depending on the complexity and cavitations of the mold.

6.Q:Is rotational molding environmentally friendly?

A:Rotational molding can be considered more environmentally friendly than some other plastic molding methods. One of the key reasons behind this is its ability to generate minimal waste. The process uses precise quantities of material, and any excess can often be recycled for future use. Additionally, rotational molding results in products that boast long lifespans and excellent durability. This aspect reduces the need for frequent replacements, subsequently decreasing the demand for new materials and reducing waste. Thus, while it’s important to continue efforts towards sustainable practices, rotational molding already has certain inherent eco-friendly advantages.
