It depends on the benefits you need.
Vacuum forming works best on products that are simple and don’t require great detail. Vacuum forming plastics is a good choice for tight budgets, time constraints, items with large dimensions and lower volume, shorter runs. We use industrial vacuum forming as a suitable replacement for other custom forming processes that use sheet metal, fiberglass or wood.
Pressure forming is recommended when aesthetics are critical. The pressure forming process creates parts with detailed textures and crisp features, similar to injection molding. And because its tooling and production are simpler and faster than injection molding, pressure forming creates plastic products at a fraction of the cost. So, the process selected is based on your needs.
