A sheet of hot plastic will be placed on top and the bed sealed, pulling the plastic down over the mold. In the most common method of high-volume, continuous thermoforming of thin-gauge products, plastic sheet is fed from a roll or from an extruder into a set of indexing chains that incorporate pins, or spikes, that pierce the sheet and ...
If the force is applied for a longer period of time, however, a relaxation process takes place whereby a plastic, irreversible deformation of the sample takes place due to the slipping and disentangling of the polymer chains. [1] To prevent the slipping and flow of polymer chains, cross-linking can be used, both chemical and physical.

A common way of making preset inductors in radios is to wind the inductor on a plastic tube. A high permeability core material is inserted into the cylinder in the form of a screw. Winding the core further in to the inductor increases inductance and vice versa. It is normally necessary to use non-metallic tools to adjust inductors.
