Learn about the differences between roto-molded and injection molded cases.
When you are ready to design your custom case with Packaging Strategies, Inc., you will likely have to ask yourself one question: injection molded or roto-molded? These two methods for building custom cases offer two methods for constructing a sturdy and long-lasting case that protects your valuable equipment. The cases primarily differ in the way they are built, as well as their weight. Deciding which case is better suited for your needs may require you to think carefully about what will go into the case and your primary design needs. Fortunately, Packaging Strategies Inc. can help you make this crucial decision.
Injection Molded Cases: Reliable Strength, Less Weight
Injection molded cases use a standard mold for each particular case size. The plastic used in these cases is often a combination of different polymers, which creates a stronger yet lighter case.
An injection molded case often has very even corners and single watertight walls. Most models come with plastic catches, air valves, and gaskets. Using single walls rather than double walls contributes to the lightweight nature of injection molded cases.
Roto-Molded Cases: Extra Toughness When Needed
Roto-molded cases are always heavier than their injection-molded counterparts. One primary reason for this is that rotationally molded cases have double walls in the corners. This is where you add extra strength, especially to protect loaded cases from drop impacts.
Case molds are placed on a large machine that rotates on the vertical and horizontal axes. Heat, speed, and cooling are the key factors that determine the final design of each case. Roto-molded cases are often custom-made to the customer’s required features, which means a slightly longer construction time.
Which Case Should You Use?
For most common applications, injection molded cases will handle the job well. However, if you need a larger case or additional strength only found in roto-molded cases, that may be the better solution.
When Should You Opt for More Protection from Roto-Molded Cases?
It’s better to be safe than sorry when protecting your valuable equipment. When should you decide to add more protection and use a roto-molded case design?
- When exceptional strength and durability are required
- The cases must withstand high impacts and rough handling
- When you need to transport equipment that is large and uniquely shaped
- When in need of exceptionally waterproof and airtight cases
- When thermal or sound insulation properties are required
