Rotational Molding   2007-10-14 SCS Cases Rotationally molded cases:  Low, Medium or High Density Polyethylene plastic pellets are ground into a powder and then, combined with color pigment as well as any other additives such as anti-stat or fire retardant materials that might be required, are then added to a case tool.   The case tool is mounted on the end of a rotating arm of the roto-mold machine, this arm then goes through a series of stations where the material melts and coats the inside of the slow speed spinning tool. The arm then moves into a water bath area where the case tool is cooled slowly and then finally to a free air spin where the tool is cooled down gradually to room temperature. The tool is then removed from the arm where an entire case emerges only to have the hardware attached and any case interior details added.    This process works best when there is a need to produce a smaller quantity of cases from 1-100 pieces. This low stress method of manufacturing produces an incredibly stout case that is imperious to almost all chemicals and is able to take abuse better than anything else on the market. The color is molded throughout the entire case and the material is virtually maintenance free.   Return to Overview
