Undercuts: Elements with inverted return lips or recessed characteristics on sidewalls are excellent applications for that one of a kind abilities of pressure forming.

Machined Aluminum: A temperature-controlled mold machined from a block of aluminum is Evidently the top-quality different for high-quality pressure forming. Tolerances may be held to marketplace standards, and plates can frequently be milled and laid up with .
