  3. Rotary wheel blow molding systems - Wikipedia

    en.wikipedia.org/wiki/Rotary_wheel_blow_molding...

    Rotary wheel blow molding systems are used for the high-output production of a wide variety of plastic extrusion blow molded articles. Containers may be produced from small, single serve bottles to large containers up to 20-30 liters in volume - but wheel machines are often sized for the volume and dimensional demands of a specific container, and are typically dedicated to a narrow range of ...

  4. Light resin transfer moulding - Wikipedia

    en.wikipedia.org/wiki/Light_resin_transfer_moulding

    A vacuum holds mold A and mold B together to result in two finished sides with fixed thickness levels. Vacuum rings around the tools hold the molds together for this process after dry fiber reinforcements are loaded into mold A before joining with mold B. The air is vacuumed out of the molds with a lower vacuum level, separate from the tooling.

  5. Injection moulding - Wikipedia

    en.wikipedia.org/wiki/Injection_moulding

    Filter for nozzle with a plastic toy next to it. Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today.

  6. Cube mold technology - Wikipedia

    en.wikipedia.org/wiki/Cube_mold_technology

    The cube mold technology is characterized by components that rotate vertically round the axis. The lower section of the mold runs on the machine base and the lower machine tie bars. The top section of the part runs on the upper machine tie bars. In this technology, components are molded within the rotating system at different steps.

  7. 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.

  8. 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 ...

  9. 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.
