    en.wikipedia.org/wiki/Hand_mould

    In the printing industry, a hand mold specifically refers to a two-part mold used for casting hand-made type.Inside the mold is a matrix. [1]In particular, it refers to a system for casting movable type, pioneered by Johannes Gutenberg, which was widely used in the early era of printing in Europe (15th-16th century).

  4. Injection moulding - Wikipedia

    en.wikipedia.org/wiki/Injection_moulding

    Simplified diagram of the process 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 ...

  5. Metal casting - Wikipedia

    en.wikipedia.org/wiki/Metal_casting

    Mold cavity: The combined open area of the molding material and core, where the metal is poured to produce the casting. Riser: An extra void in the mold that fills with molten material to compensate for shrinkage during solidification. Gating system: The network of connected channels that deliver the molten material to the mold cavities.

  6. Transfer molding - Wikipedia

    en.wikipedia.org/wiki/Transfer_molding

    Transfer molding (BrE: transfer moulding) is a manufacturing process in which casting material is forced into a mold.Transfer molding is different from compression molding in that the mold is enclosed [1] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact.

  8. Riser (casting) - Wikipedia

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

    A bronze casting showing the sprue and risers. A riser, also known as a feeder, [1] is a reservoir built into a metal casting mold to prevent cavities due to shrinkage.Most metals are less dense as a liquid than as a solid so castings shrink upon cooling, which can leave a void at the last point to solidify.

  9. Sprue (manufacturing) - Wikipedia

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

    A sprue is a large diameter vertical channel through which liquid material is introduced into a mold. It connects the pouring basin to the runner. In many cases it controls the flow of material into the mold. During casting or molding, the material in the sprue will solidify and need to be removed from the finished part. It is usually tapered ...
