2. Permanent mold casting - Wikipedia

   en.wikipedia.org/wiki/Permanent_mold_casting

   Low-pressure permanent mold (LPPM) casting uses a gas at low pressure, usually between 3 and 15 psi (20 to 100 kPa) to push the molten metal into the mold cavity. The pressure is applied to the top of the pool of liquid, which forces the molten metal up a refractory pouring tube and finally into the bottom of the mold.

3. 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.

4. Metal casting - Wikipedia

   en.wikipedia.org/wiki/Metal_casting

   Shell molding is similar to sand casting, but the molding cavity is formed by a hardened "shell" of sand instead of a flask filled with sand. The sand used is finer than sand casting sand and is mixed with a resin so that it can be heated by the pattern and hardened into a shell around the pattern. Because of the resin and finer sand, it gives ...

5. Chill (casting) - Wikipedia

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

   A chill is an object used to promote solidification in a specific portion of a metal casting mold.Normally the metal in the mould cools at a certain rate relative to thickness of the casting.

6. 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.
