SKB Injection Molded Case

Molding processes are all very similar: a material, usually a thermoplastic, takes on the shape of a cavity. That cavity is created by a mold tool, and is a 3D mirror image of the finished part. What differs between molding processes is how the material gets into the cavity. It can be placed in it, as in rotational or compression molding, or it can be forced in under pressure, which is injection molding. Continue reading

Why HDPE Transit Cases are Rotationally Molded
A Rotationally Molded Case

High-density polyethylene (HDPE) makes excellent transit cases, especially when formed by the rotational molding process. HDPE is lightweight, strong, corrosion-proof, and resistant to solvents and acids.  It remains stable through a wide temperature range. Rotational molding (roto-molding for short) distributes HDPE powder over the surfaces of a mold.  The mold is heated and rotated.  This allows liquid HDPE to create hollow shapes with complex geometries.
