More about roto molded cases and roto molding

The process of roto molding was actually invented in the 19th century and it has been used popularly since the 1940’s but in recent decades, it has increased greatly in usage due to improvements in the rotational molding process.

Rotational molding uses a heated mold that melts the plastic and rotates so that the plastic forms to the inside of the metal mold. This process is different from other processes related to thermoplastics, such as injection molding and blow molding.

Differences between the processes used in creating roto molded cases versus injection molded cases:

Because this process requires the mold to be heated and cooled, it takes considerably longer to produce product than other molding process like injection molding. Roto molding has a number of advantages including that it is much easier to produce larger cases using rotational molding. Rotational molding will naturally produce thicker plastic corners and edges with thinner flat walls making it the ideal solution for a lightweight, yet very rugged and durable hard case. Roto molding also creates much less waste than other molding processes; excess material is ground down to be reused. From the manufacturer’s perspective, roto molding also offers the ability to experiment with wall thickness to achieve an optimal ratio of material used to end product quality; other molded cases do not benefit from this option.

All of this requires more care on the part of the manufacturer: roto molded cases are produced in less mass than other molded cases and tend to have superior strength and durability. This makes the hard case hardware and features much more easily customizable.
