  2. 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 ...

  3. Polymer solution casting - Wikipedia

    en.wikipedia.org/wiki/Polymer_solution_casting

    The polymer solution casting process utilizes a mandrel, or inner diameter mold, that is immersed in a tank of polymer solution or liquid plastic that has been specifically engineered for the process. Due to a combination of thermal and frictional properties, the polymer solution then forms a thin film around the mold. [1]

  4. Injection mold construction - Wikipedia

    en.wikipedia.org/wiki/Injection_mold_construction

    Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.

  6. 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 ...

  7. Vacuum assisted resin transfer molding - Wikipedia

    en.wikipedia.org/wiki/Vacuum_assisted_resin...

    Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow. [2]

  8. 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.

  9. Fusible core injection molding - Wikipedia

    en.wikipedia.org/wiki/Fusible_core_injection_molding

    However, these types of machines cost approximately 35% more than horizontal machines, require more space, and require two bottom molds (because one is in the machine during the cycle and the other is being unloaded and loaded with a new core), which adds approximately 40% to the tooling cost. For small parts, horizontal injection molding ...
