Looking down its length in the same manner you’d judge a two-by-four for straightness, he admires the part’s flatness. Molded for a Dodge Ram truck from thermoplastic polyolefin (TPO), the tailgate top cover is reflective of the Axiom Group’s core competency: functional plastic parts for automotive, molded in black and usually with a Class A finish. Axiom Group currently operates six injection molding machines at its production facility in Capac, Michigan.

Before design and mold changes determined by Axiom Group, the same “gun-sight” spot check for this particular part revealed banana-shaped warpage. Axiom notes that its engineering team uses advanced design for manufacturing (DFM) software to study every part it produces. These studies determine best-approach solutions like windage modification, design updates or injection strategies to counter the effect of defects like warp. Part of a two-component assembly that’s welded together, the new design required the addition of a lip and subsequently resulted in an undercut and a parting line. Axiom stays up to date with evolving injection tooling technology, incorporating design elements to render the parting line “almost invisible”, according to Stockwell.
