2. Mold (cooking implement) - Wikipedia

   en.wikipedia.org/wiki/Mold_(cooking_implement)

   Bundt-style silicone and metal pans (2008) Late 19th- and early 20th-century food molds. A mould (British English) or mold (American English), is a container used in various techniques of food preparation to shape the finished dish. The term may also refer to a finished dish made in said container (e.g. a jello mold). [1]

3. Core (manufacturing) - Wikipedia

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

   This allows the entire mold to be made from green sand and from removable patterns. The disadvantage of this is more mold-making operations are required, but it is usually advantageous when the quantities are low. However, if large quantities of casting are required, it is usually more cost effective to simply use a core. [6]

4. Rotational molding - Wikipedia

   en.wikipedia.org/wiki/Rotational_molding

   One of the first applications was to manufacture doll heads. The machinery was made of an E Blue box-oven machine, inspired by a General Motors rear axle, powered by an external electric motor and heated by floor-mounted gas burners. The mold was made of electroformed nickel-copper and the plastic was a liquid polyvinyl chloride (PVC) plastisol ...

5. Molding (process) - Wikipedia

   en.wikipedia.org/wiki/Molding_(process)

   A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. [2] The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object.

6. Pattern (casting) - Wikipedia

   en.wikipedia.org/wiki/Pattern_(casting)

   When the pattern is to be removed from the sand mold, there is a possibility that any leading edges may break off, or get damaged in the process. To avoid this, a taper is provided on the pattern, so as to facilitate easy removal of the pattern from the mold, and hence reduce damage to edges. The taper angle provided is called the Draft angle ...

7. Investment casting - Wikipedia

   en.wikipedia.org/wiki/Investment_casting

   Produce wax patterns: Although called wax patterns, pattern materials may also include plastic and frozen mercury. [6] Wax patterns can be produced in one of two ways. In one process, the wax is poured into the mould and swished around until an even coating, usually about 3 mm (0.12 in) thick, covers the inner surface of the mould.

8. Injection moulding - Wikipedia

   en.wikipedia.org/wiki/Injection_moulding

   Circular pattern around gate, normally only an issue on hot runner molds Injection speed is too fast, gate/sprue/runner size is too small, or the melt/mold temp is too low. Jetting: Jetting is a snake-like stream which occurs when polymer melt is pushed at a high velocity through restrictive areas. Poor tool design, gate position or runner.

9. Full-mold casting - Wikipedia

   en.wikipedia.org/wiki/Full-mold_casting

   The pattern is then coated with a refractory material. The coated pattern (2) is placed in a flask and packed carefully with green sand (4) or a chemically bonded sand. Finally, the molten metal (1) is poured into the mold, which vaporizes the foam (3) allowing the metal to fill the entire mold. The vapor is simultaneously extracted from the ...
