What is the difference between injection molding and thermoforming?
A. Thermoforming involves making custom plastic enclosures by preheating a flat sheet of plastic and bringing it into contact with a mold whose shape it takes. This can be done by vacuum, pressure and or direct mechanical force. The process offers close tolerances, tight specifications, and sharp detail for your custom plastic parts. Injection molding involves taking plastic of your choice in the form of pellets or granules and heating this material until a melt is obtained. Then the melt is forced into a split-die chamber/mold where it is allowed to “cool” into the desired shape. The mold is then opened and the part is ejected, at which time the cycle is repeated again.
