Thermoforming Plastics

About Vacuum Pressure & Heavy Gauge Forming

Thermoforming plastics generally uses one or both of two processes; vacuum forming or pressure forming. FLOE Thermoforming systems are either vacuum forming or vacuum and pressure forming systems.

The following diagrams illustrate vacuum and pressure forming processes.


Thermoforming-Diagram-VacuumVacuum forming pulls the plastic sheet material around the mold where a vacuum is applied inside the mold such that very small holes in the mold pull the air from between the plastic sheet material and the mold. The plastic sheet material then forms around the mold. Vacuum forming allows for sharper details, undercuts, tighter tolerances and molded in textures.





Thermoforming-Diagram-PressurePressure forming in conjunction with vacuum forming, applies additional outside air pressure on the plastic sheet material to aid in forming. Pressure forming, in addition to vacuum forming, allows for more complex shapes, parts with vents and louvers, and parts with even tighter tolerances.

Heavy Gauge Custom Vacuum Forming

FLOE Thermoforming offers vacuum forming and pressure vacuum forming systems capable of forming materials up to .600 mils (6/10″). FLOE’s Thermoforming machines provide the fastest cycle times and best cost efficiency when forming extremely large form-factor heavy gauge parts. Our machine strategy revolves around providing the right value proposition to our OEMs and Thermoforming Partners that they never thought possible. FLOE Thermoforming allows for the conversion of steel, fiberglass, composites and other materials to lighter weight, more durable and cosmetically appealing plastic part technologies. Conversion part examples include: very large agricultural equipment parts currently made of steel and fiberglass, very large steel waste dumpsters, very large composite boat hulls… the list is endless. Just let us know what you have in mind or need and our team will be happy to offer FLOE Thermoforming solutions!
