The design of vacuum forming molds includes batch size, molding equipment, precision conditions, geometric design, dimensional stability and surface quality.
1. The size of the batch is used for experiments. When the mold output is small, it can be made of wood or resin. However, if the experimental mold is used to obtain data on shrinkage, dimensional stability, and cycle time of the product, a single cavity mold should be used for the experiment and it can be used under production conditions. Molds are typically made of gypsum, copper, aluminum or aluminum-steel alloys, and aluminum-resins are rarely used.
