2. Polycarbonate - Wikipedia

   en.wikipedia.org/wiki/Polycarbonate

   Polycarbonate. Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many ...

   Short video on injection molding (9 min 37 s) Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.

4. Injection moulding - Wikipedia

   en.wikipedia.org/wiki/Injection_moulding

   Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting), glasses, elastomers, confections, and most commonly ...

   Blow molding (or moulding) is a manufacturing process for forming hollow plastic parts. It is also used for forming glass bottles or other hollow shapes. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with softening ...

6. Plastic compounding - Wikipedia

   en.wikipedia.org/wiki/Plastic_compounding

   Plastic compounding scheme. Compounding consists of preparing plastic formulations by mixing and/or blending polymers and additives in a molten state to achieve the desired characteristics. [1] These blends are automatically dosed with fixed setpoints usually through feeders/hoppers. It is mostly a blend of copolymers such as ABS, SAN, SMA etc ...
