3. Molded pulp - Wikipedia

   en.wikipedia.org/wiki/Molded_pulp

   This newest form of molded pulp is the highest quality of thin-walled products available today. The process uses "cure-in-the-mold" technology which produces well defined, smooth-surfaced molded pulp products. After being formed, the product is captured in heated forming molds that presses and densifies the molded products.

Vacuum forming is a simplified version of thermoforming, where a sheet of plastic in various forms of High Impact Polystyrene Sheet (HIPS) for low impact products, or ABS for bathroom shower trays, and HDPE for exterior vehicle parts, plus various other types of vacuum ...

5. Rotational molding - Wikipedia

   en.wikipedia.org/wiki/Rotational_molding

   After the mold is rotated and all the surfaces are sufficiently coated with the melt-flow, the rotation stops and the melt-flow is allowed to pool at the bottom of the mold cavity. [20] Wall thickness is important for corner radii as well. Large outside radii are preferable to small radii. Large inside radii are also preferable to small inside ...

   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.

9. 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 ...
