WebGate depth for an ABS part needs to be 75 percent of the part’s wall thickness. For a .100-inch-thick wall, the edge gate depth should be .075 inch. Since the land is based on the depth I follow the rule that the gate land should be half the gate depth, but not exceed .030 inch. In this case, I use the default dimension of .030 inch. The relative permittivity (in older texts, dielectric constant) is the permittivity of a material expressed as a ratio with the electric permittivity of a vacuum. A dielectric is an insulating material, and the dielectric constant of an insulator measures the ability of the insulator to store electric energy in an electrical field. Permittivity is a material's property that affects the Coulomb force between two …
