Hardigg cases for commercial, industrial and military applications are made of rotationally molded plastic. This rotomolding process results in high impact protection and seamless airtight and watertight packaging. Hardigg offers 295 standard case sizes, the largest selection in the industry.

How Hardigg Cases Are Produced

Rotational molding, or rotomolding, is a process in which plastic resins are loaded into a mold that is heated as it is rotated, both vertically and horizontally. The rotation causes the plastic to coat the inner surface of the mold, and the heat fuses it. Then the mold is gradually cooled by air or water spray. The rotation continues during the cooling process in order to maintain even walls.

Hardigg cases are exclusively produced by rotomolding because the process results in seamless cases which are uniform in thickness and have more material in corners, where the most stress occurs. Complex design elements can be incorporated into the molds, since no core mold is required. Also, the material used is not stressed during production as it is in thermoforming, pressure forming or injection molding. This lack of stress results in a stronger finished product.

These rotomolded Hardigg cases are lighter than metal or fiberglass, and therefore less expensive to ship. They are airtight, watertight, dust-proof and corrosion-proof. Hardigg also offers customized foam interiors to protect against shock and vibration. And Hardigg takes the personnel into consideration as well as the product: their cases are designed for the easiest and most efficient handling, loading, and stacking.
