Shrinkage of the sheet during forming occurs with all materials, and must be factored into mold design. The level of shrinkage will vary according to:
*0.4-0.5% for female pressure molds
Tools can be designed with multiple cavities to allow for higher production rates, and to improve yields from single sheets by minimizing trim scrap. Single tools with molds for different part configurations can also be designed.
Guideline: space mold cavities at 2x the part height to allow for good material distribution and wall thickness uniformity.
