2. Die forming (plastics) - Wikipedia

   en.wikipedia.org/wiki/Die_Forming_(Plastics)

   Die swell is an expansion of the melt as the pressure is released, and is dependent on polymer chemistry and die design. After curing, the solid, continuous part is drawn onto a take-up roller or cut into transportable lengths, depending on the type of part. This process may vary significantly depending on the type of die and extrusion process. [1]

3. Extrusion - Wikipedia

   en.wikipedia.org/wiki/Extrusion

   Rubber extrusion is a method used to make rubber items. In this process, either synthetic or natural rubber that hasn't been hardened yet is put through a machine called an extruder. This machine has a desired shaped mold and a pressurized conveyor system. The rubber gets heated and softened in the extruder, making it bendable.

4. Die swell - Wikipedia

   en.wikipedia.org/wiki/Die_swell

   Die swell occurs in instances of polymer extrusion, in which a stream of polymeric material is forced through a die, a specialized tool in manufacturing to shape or cut polymeric materials. Die swell is an instance where a polymer stream is compressed by entrance into a die, and is followed by a partial recovery or "swell" back to the former ...

5. Die (manufacturing) - Wikipedia

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

   A die is a specialized machine tool used in manufacturing industries to cut and/or form material to a desired shape or profile. Stamping dies are used with a press, [1] as opposed to drawing dies (used in the manufacture of wire) and casting dies (used in molding) which are not. Like molds, dies are generally customized to the item they are ...

6. Plastic extrusion - Wikipedia

   en.wikipedia.org/wiki/Plastic_extrusion

   This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow.

7. Slot-die coating - Wikipedia

   en.wikipedia.org/wiki/Slot-die_coating

   Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.

8. Ceramic mold casting - Wikipedia

   en.wikipedia.org/wiki/Ceramic_mold_casting

   The slurry hardens almost immediately to a rubbery state (the consistency of vulcanized rubber). The flask and pattern is then removed. The flask and pattern is then removed. Then a torch is used to ignite the mold, which causes most of the volatiles to burn-off and the formation of ceramic microcrazes (microscopic cracks).

9. Rubber pad forming - Wikipedia

   en.wikipedia.org/wiki/Rubber_pad_forming

   Rubber pad forming process, 1: bottom of the press. 2: lower die. 3: sheet metal. 4: rubber pad. 5: top of the press. Rubber pad forming (RPF) is a metalworking process where sheet metal is pressed between a die and a rubber block, made of polyurethane. Under pressure, the rubber and sheet metal are driven into the die and conform to its shape ...
