The manually operated EXO-FORMER 24 forms thermoplastic sheets using the basic
principles of vacuum forming/thermoforming. A rigid thermoplastic sheet is held immobile
above a heat source until it reaches flow temperature. It is then moved over
and on to a vacuum table where an internal motor or an external pump, or a
combination of the two, quickly evacuates the air trapped between the
plastic and the mold. This creates the negative air pressure required to
allow the positive pressure of the Earth�s atmosphere to force the warm
plastic completely around the mold. At this point the plastic cools back to
its original, rigid state, yet now the plastic is no longer flat, but
Only thermoplastics can be used with the EXO-FORMER 24, because only this
type of plastic material can be softened by heat and returned to its
original rigidity when cooled.
Common types of thermoplastics include Polystyrene, ABS, PVC, PET-G, CAB,
Low and High Density Polyethylene, Polypropylene, Polycarbonate and Acrylic.
It should be noted that terms such as Vacuum Forming, Vacuforming
and Thermoforming are used interchangeably in the plastics industry to refer
to the same process. Likewise, Vacuum Forming machines are also refered to
as Vacuformers, Thermoformers or Vacuumform Machines in the thermoplastics
industry. A finished part produced by one of these machines is often refered
to as a Vacuform or Thermoform.
While it appears that the thermoplastics industry generally refers to these
machines as Thermoformers or Thermoforming machines, we at Vacugenic Corporation
prefer the term Vacuum Forming Machine. It is our view that the word Thermoforming
can be misleading. This is because while many industrial processes use heat to form
items, not all use a vacuum as part of the process. Vacuum Forming, on the other hand,
clearly implies something formed with the aid of a vacuum.
It is in this light that Vacugenic, our company name, was formed, coming from the terms "genic"
and "vacuum", literally meaning "produced by a vacuum".
