Issues one should avoid in the Rotational Molding process


Rotational Molding is a process where many types of hollow pieces are created with the plastic molding technique. The product is molded in high temperatures but low-pressure plastic with heat and biaxial rotations so as to produce concave in the required shape and design. It is an entirely low-pressure process that is inexpensive and can be used for complex requirements.

It was difficult for the people of that traditional era to mold the product into a new one. New air has emerged after rotational Molding has come up with great benefits inspiring them to design product in such a way that people couldn’t manufacture traditionally. The Rotational Molding method is eco-friendly, and it can be recycled too.

After the completion of the rotational molding design process, we will step in moving into the manufacturing process, which is to complete a rotational mold or tool. Molds should be constructed so perfectly and accurately that it does not hamper the productivity and does not affect the schedule which should always be on track.

Mold costs are usually the deciding factor of the project, dictating the mold production process selection. Finding a rotational molding provider with an in-house mould or metals shop is also critical to the success of most rotational molding customers since they may create, change, or fix moulds in-house, reducing downtime for maintenance. 

Issues which you can face

  • One of the most basic complaints with rotationally molded product design is flat walls. The rotomolding method makes it impossible to accomplish long or wide flat surfaces. Usually, through the rotational molding technique, they attempt to shape a hollow vessel with little interior structure or no. Experienced rotomolding practitioners would resist large flat surfaces instead of adding any shape or geometry into the product.
  • One of the significant distinctions between the rotational molding and other plastics molding processes is that the raw materials are crushed to powder. In contrast, many other plastics molding processes use pellets or film. To avoid material flow issues, you must leave at least five times the wall thickness between any walls, ribs or surface of the product.
  • Another issue people commonly face is sharp corners. During the early rotational mold designing, sharp corners should be avoided whenever possible It reduces the flow of materials through the mold. Due to the inability of the substance to move adequately through the mold, voids in the sharp corners would most likely not fill incorrectly because this material will not be able to flow through the mold.

The Final Verdict

Rotational Molding is a versatile plastic manufacturing technique, and it can be used to produce parts for a variety of industries. In almost every business segment, rotationally molded plastic materials are found. So, this manufacturing method is adopted by everyone from the furniture industry to the medical department nowadays. The rotational molding manufacturers are ecstatic with the present boom and anticipate better earnings by the end.
