2. Shut-off nozzle - Wikipedia

   en.wikipedia.org/wiki/Shut-off_nozzle

   Needle Shut-off Nozzle type HP - pneumatic or hydraulic actuation. The melt flow is shut off via a melt channel-axis positioned needle moving back and forth according to actuation. This nozzle type shuts off the melt stream directly at the nozzle orifice-mold interface which prevents drooling.

3. Injection molding of liquid silicone rubber - Wikipedia

   en.wikipedia.org/wiki/Injection_molding_of...

   Injection molding of liquid silicone rubber (LSR) is a process to produce pliable, durable parts in high volume. Liquid silicone rubber is a high purity platinum cured silicone with low compression set, good stability and ability to resist extreme temperatures of heat and cold ideally suitable for production of parts, where high quality is ...

   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 ...

   Similar type of feedstock is also used in the Metal Injection Molding (MIM) and in the Ceramic Injection Molding (CIM) processes. The extruder pushes the material towards a heated nozzle thanks to the controlled axial movement of a piston inside a heated barrel, or the controlled axial rotation of a screw inside a heated barrel,

7. Multi-material injection molding - Wikipedia

   en.wikipedia.org/wiki/Multi-material_injection...

   Multi-material injection molding (MMM) is the process of molding two or more different materials into one plastic part at one time. [1] As is the case in traditional injection molding, multi material injection molding uses materials that are at or near their melting point so that the semi-liquidous material can fill voids and cavities within a pre-machined mold, thus taking on the desired ...
