The housing featured dimensions of 3.12″ in length, 1.625″ in width, 4.625″ in height, with an outside diameter of 3.00″. The fan had an outside diameter of 2.670″, and a height of .869″. Both sections were required to meet dimensional tolerances of ±0.005″, and angular tolerances of ±0.5°. All of our manufacturing processes are subject to stringent quality measure; these two components received dimensional inspections prior to assembly and delivery. We currently manufacture 30,000 sets of these parts annually.

Blow molding is a manufacturing process that involves turning plastic material into a hollow plastic component. The first step is melting and extruding plastic pellets into a tube (i.e., parison). The tube is then enclosed within a pre-formed mold. Next, air is blown into the contained tube to force the material to conform to the shape of the mold. Finally, the material is allowed to cool and harden so it maintains the hollow form. The process can be used to manufacture parts and products in various shapes and sizes.
