Benefits of Rotationally Molded Transit Cases


Rotationally molded transit cases make traveling much easier.

Transit storage demands strong cases that will protect your goods through long periods of transportation and stand up to moving, shifting, and sometimes rough treatment. The strength and transportability of your case options are directly impacted by the production methods by which they are made. Rotational molding (or roto-molding) makes especially strong transit cases from high-density polyethylene (HPDE), a sturdy but lightweight material that resists corrosion and damage by solvents and acids. HPDE powder is distributed over the surface of a mold before heating and rotating the mold to allow for the liquid HPDE to perfectly fit the shape of your mold. This ease of production and applicability to a wide variety of shapes and sizes make rotationally molded cases perfect for your transit needs. Following are just a few of the benefits of using rotationally molded transit cases.


While some other production methods will require larger tools and equipment to create larger cases and molds, roto-molding is applicable to a wide range of shapes and sizes. This flexibility makes roto-molding a great choice for making cases that meet the exact specifications of your storage and transit needs, at a consistently lower cost.

Added Strength

Since the rotational molding method entails a coat of powdered HPDE heated and rotated in a mold, the corners are thicker with more material. This is a common area for breakage in transit cases, which are put through a lot in their lifetime. The extra material in the corners helps to prevent this kind of breakage from dropping, shifting, or generally rough transit. An added benefit to the way rotational molding shapes the corners of your transit cases is that they are designed to leave no sharp corners. This makes them easier to move and transport safely and prevents injuries for transit employees.

Increased Stability

One problem with traditional molding production is the residual stresses often left in transit case material. With roto-molding, there are no residual stresses left behind from production, making your transit cases more stable. With no residual stresses, your cases will be stronger and resistant to distortion and other types of damage.

Long Life

Not only are rotationally molded transit cases more resistant to damage and warping, but they will also maintain a newer look for longer, which will extend their use-life and add to their cost-effectiveness. The color of your cases, for example, is blended throughout the material at the beginning stages of the production process. This will allow them to maintain its new appearance despite rough treatment and years of use. Additionally, any number of case colors are available through roto-molding, meaning your transit cases can come in any number of colors to allow for easy organization, identification, and inventory.
