Speaker Notes:
eTools are "stand-alone," interactive, Web-based training tools on occupational safety and health
topics. They are highly illustrated and utilize graphical menus. Some also use expert system
modules, which enable the user to answer questions, and receive reliable advice on how OSHA
regulations apply to their work site.
Here is an OSHA eTool, Thermoforming Machines module of the Machine Guarding eTool, that was
developed as a product of OSHA’s Alliance with the Society of the Plastics Industry, Inc. (SPI)
which was added to our Web pages September 2007:
Thermoforming is a manufacturing process using thermoplastic sheet or film. Employees load the roll
of plastic sheet or film on the roll-fed thermoformer roll stand and then thread it through the end
feed rollers. When the machine is activated, the plastic sheet or film is advanced into the oven
for heating and then into the form station where the parts are formed and then advanced to the trim
station. The plastic web is then automatically wound on the scrap rewinder or it can be trimmed and
fed into a tub, conveyor, or directly in to a grinder. If the scrap is not fed directly into a
grinder, it is typically baled and then manually fed into a web grinder/granulator.
The following illustrate the areas where potential hazards may be found and possible solutions may
be implemented when using thermoforming machines.
