Blow Molding   2007-10-14 SCS Cases Blow molded cases: Most often molded of High Density Polyethylene which is blown with air pressure against the inside surface of the case mold. The case is made up of a two part tool. Once the part is formed, the tool is cooled with water and the part is removed from the case tool. The molded plastic case shell then goes to the final assembly area where secondary operations like adding the interiors or case labels are added. Most blow molded cases are double wall construction to help add strength to the case. The exterior of the case is textured to hide scuffs and scrapes. Most tools have an area on the lid where a customer can affix a label with either company or product name making the case appear as if they are private labeled.   Return to Overview
