... force of approximately 9 MN (1000 tonf). This low pressure also tends to result in low internal stresses and very accurate dimensions. Lower-cost tooling is possible with the low pressures, but mold surface temperature control is critical to achieving dimensional accuracy. A small amount of blowing...

..., especially interior corners. Resin Casting Casting is one of the most basic low-pressure molding processes and utilizes hollow tools or molds, sometimes with a vacuum assist to ensure complete filling of the mold. The low molding pressures allow for the use of low-cost tools, but this can also result...
