Popular Shipping Cases: The Difference Between Roto-Molded & Injection Molded Cases

The term “Shipping Cases” refers to several different types of protective cases, including Roto-Molded Cases and Injection Molded Cases. So what are the major differences between these two popular types of shipping cases?

Roto-Molded Cases

Roto-molded cases, a term short for rotationally molded cases, refers to a style of shipping cases manufactured using the rotational molding process. A plastic charge is placed into the case mold, which is slowly rotated in two planes as heat transfer causes the plastic charge to conform to the mold. Next, using either air, water spray, or a combination of the two, the mold is then cooled. And finally, the case is removed from the mold and a new plastic charge is inserted.

The end result is a durable and cost-effective shipping case.

Injection Molded Cases

An injection molded case is similar to a roto-molded case in the way that it performs after manufacturing. However, the manufacturing process for these cases is extremely different. The injection molding process involves feeding plastic into a heated barrel, mixing it, and pouring it into a mold. The plastic eventually cools and hardens to the specified configurations.

The Difference Between Roto-Molded & Injection Molded Cases

At the end of the day, the only major difference is the manufacturing processes for both Roto-Molded cases and Injection Molded cases. Other than that, these cases are very similar in a lot of ways. Both types of cases offer superior strength and durability. Both types of cases are designed to survive the most brutal situations and ensure the safety of your delicate equipment. Both types of cases are available through Packaging Strategies Inc. (PSI).
