2. Vacuum forming - Wikipedia

   en.wikipedia.org/wiki/Vacuum_forming

   A simple visualization of the forming process Vacuum forming machine to produce inner liner/food liner of refrigerator. Vacuum forming is a simplified version of thermoforming, where a sheet of plastic in various forms of High Impact Polystyrene Sheet (HIPS) for low impact products, or ABS for bathroom shower trays, and HDPE for exterior vehicle parts, plus various other types of vacuum ...

3. Vacuum assisted resin transfer molding - Wikipedia

   en.wikipedia.org/wiki/Vacuum_assisted_resin...

   Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow.

   The Vac-u-form, was a toy invented by Eddy Goldfarb and released by Mattel in the 1960s around 1961 with the trademark filed on October 8, 1962. [1]Based on the industrial process of vacuum forming, a rectangular piece of plastic was clamped in a holder and heated over a metal plate.

5. Plastic forming machine - Wikipedia

   en.wikipedia.org/wiki/Plastic_forming_machine

   Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, and stamped to a specific shape in a 2-part mold. Or a vacuum can be used to pull the plastic sheet onto the mold in a simplified process known as vacuum forming. The excess material is trimmed off and recycled.

6. Resin casting - Wikipedia

   en.wikipedia.org/wiki/Resin_casting

   Specialist equipment can enable closed molds to be filled whilst under vacuum, a process known as resin vacuum casting, where air and gas bubbles are completely removed from the cast part. Pressure and/or centrifugal force can be used to help push the liquid resin into all details of the mold. The mold can also be vibrated to expel bubbles.

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 ...
