Sorry, we do not build custom size formers. The setup costs and R&D to build a particular size former are staggering and we cannot alter our production line to build one unique item. The ThermaPress VF1 is also not scalable due the amount of engineering and critical dimensions that went into designing it. If you think you want a bigger, larger vacuum former than the ThermaPress VF1 . . we strongly recommend against it. Tests in our shop confirm that two regular sized vacuum formers will out produce and are much more efficient to run than one large sized vacuum former. Two formers hands down will out produce in volume a single large vacuum former of equal capacity. In addition, overall costs of ownership are much greater on a larger vacuum former. Larger membranes can be very costly to replace if ruptured.
