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. Evaporation (deposition) - Wikipedia

   en.wikipedia.org/wiki/Evaporation_(deposition)

   Evaporation takes place in a vacuum, i.e. vapors other than the source material are almost entirely removed before the process begins. In high vacuum (with a long mean free path), evaporated particles can travel directly to the deposition target without colliding with the background gas. (By contrast, in the boiling pot example, the water vapor ...

4. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   [5] This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow.

5. Acrylic resin - Wikipedia

   en.wikipedia.org/wiki/Acrylic_resin

   Acrylic resin is a common ingredient in latex paint (UK: "emulsion paint"). Latex paints with a greater proportion of acrylic resin offer better stain protection, greater water resistance, better adhesion, greater resistance to cracking and blistering, and resistance to alkali cleaners compared to those with vinyl. [2]

6. Vacuum chamber - Wikipedia

   en.wikipedia.org/wiki/Vacuum_chamber

   The vacuuming is continued for another 2 to 3 minutes to make certain all of the air has been removed from the material. Once this interval is reached, the vacuum pump is shut off and the vacuum chamber release valve is opened to equalize air pressure. The vacuum chamber is opened, the material is removed and is ready to pour into the mold.

7. Suspension polymerization - Wikipedia

   en.wikipedia.org/wiki/Suspension_polymerization

   The morphology of the polymer can be changed by adding a monomer diluent, an inert liquid that is insoluble with the liquid matrix. The diluent changes the solubility of the polymer in the monomer and gives a measure of control over the porosity of the resulting polymer. [6] The polymer beads that result can range in size from 100 nm to 5 mm.
