What are the Basic Requirements to Make the molds of Rotational Molding?

Once a design of rotomolded product is successfully completed and confirmed, the next step is to make a mold for manufacturing. Mold or tooling is a critical component for any plastics molding process. This is what is used to shape the product. How well the mold is designed and manufactured will greatly dictate the quality of the part produced from the mold.

When it comes to rotational molding, having the right molds is half the job done. Before the start of the making the molds, a number of specifics need to be taken into consideration in order to increase efficiency and improve product quality. Below are the basic requirements.

• Mold structure is reasonable. The mold can be opened and closed easily, and the inserts are easy to mold in.
• The material selected to fabricate the mold has the strength in order to avoid the damage or minimize the repairing for a long lifespan.
• The mold wall thickness is appropriate to allow the heat source to quickly transfer heat into the powder, also allow for cooling the product fast, which is beneficial to speed up the rotational molding process.
• It is critical that the molds be designed accurately and completely for the process in effort to keep the process efficient and on track. The inner surface is smooth and the cavity is clean. The internal space gap is enough for material flow.
• Mold costs are typically the determining factor of the project, which will dictate the selection of the mold manufacturing process
• Timeline for the project is also important, which means that products can be available on the market more quickly.
