2. Thermoforming - Wikipedia

   en.wikipedia.org/wiki/Thermoforming

   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 ...

3. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   The type of acrylic used in tanning beds is most often formulated from a special type of polymethyl methacrylate, a compound that allows the passage of ultraviolet rays. Sheets of PMMA are commonly used in the sign industry to make flat cut out letters in thicknesses typically varying from 3 to 25 millimeters (0.1 to 1.0 in).

4. Water jet cutter - Wikipedia

   en.wikipedia.org/wiki/Water_jet_cutter

   The term abrasive jet refers specifically to the use of a mixture of water and an abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.

5. Vacuum forming - Wikipedia

   en.wikipedia.org/wiki/Vacuum_forming

   A sheet of vacuum-formed plastic. The pieces needed (in this case parts for a model aeroplane) will need to be cut out of the sheet. Once a vacuum forming has been created out of a sheet of plastic, a finishing operation will be needed in most cases to turn it into a usable product. Common vacuum forming finishing methods include:

6. Die (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Die_(manufacturing)

   Steel-rule die, also known as cookie cutter dies, are used for cutting sheet metal and softer materials, such as plastics, wood, cork, felt, fabrics, and paperboard. The cutting surface of the die is the edge of hardened steel strips, known as steel rule. These steel rules are usually located using saw or laser-cut grooves in plywood.

7. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   A common post-extrusion process for plastic sheet stock is thermoforming, where the sheet is heated until soft (plastic), and formed via a mold into a new shape. When vacuum is used, this is often described as vacuum forming. Orientation (i.e. ability/ available density of the sheet to be drawn to the mold which can vary in depths from 1 to 36 ...
