  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 ...

    By using degradable polymers, costs due to waste transportation, landfill maintenance, new landfill excavation and environmental hazard control can be avoided. Lost end-of-life plastic potential: [ 5 ] processes such as energy recovery of the plastic by incineration or biological treatment and material recovery by recycling have to be taken ...

  4. Thermoforming - Wikipedia

    en.wikipedia.org/wiki/Thermoforming

    Its simplified version is vacuum forming. In its simplest form, a small tabletop or lab size machine can be used to heat small cut sections of plastic sheet and stretch it over a mold using vacuum. This method is often used for sample and prototype parts. In complex and high-volume applications, very large production machines are utilized to ...

  5. 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 ...

  6. Poly(methyl methacrylate) - Wikipedia

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

    It is a transparent thermoplastic, used as an engineering plastic. PMMA is also known as acrylic, acrylic glass, as well as by the trade names and brands Crylux, Hesalite, Plexiglas, Acrylite, Lucite, and Perspex, among several others . This plastic is often used in sheet form as a lightweight or shatter-resistant alternative to glass. It can ...

  7. 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.

    The UV performance test data can be found on our data sheets for each specific grade. Light Stability Characteristics Ultraviolet (UV) Stabilization Plastics are attacked and deteriorate when exposed to direct sunlight. When plastic tanks absorb the sun's ultraviolet light, the UV energy excites the polymers’chains, causing them to break.
