computation of core working dimension in mold design
computation of core working dimension. Cores are used to mold the internal shape of plastic parts. […]
computation of core working dimension. Cores are used to mold the internal shape of plastic parts. […]
computation of cavity working dimension. Cavities are mold parts for forming the external shape of plastic parts. […]
manufacturing tolerance. The manufacturing tolerance directly influences the dimension tolerance of plastic parts, […]
the shrinkage of plastic parts, due to the nature of plastic ( to expand when hot and to shrink when cold), the dimension of plastic parts after molding and cooling is smaller than that of the cavity.
today we discuss the working dimension of molding parts. Because it refers to the dimension in direct contact with plastic in cavity and core, […]
today morning, you want to know some things about thread ring cavity, actually thread ring cavity is a kind of active insert used to mold the outer thread of the plastic parts, […]
molding parts refer to those in direct contact with plastics to form the shape of plastic parts, wherein those constituting the contour of the plastic parts are called cavities and those constituting the internal shape of the plastic parts are called cores. […]
the material is selected for the part molding area according to the surface roughness of the plastic part and the expected number of injection cycles. […]
the mold surface roughness is a very important technical parameter in mold making, because the surface finish of the molding area directly affects the surface roughness of the plastic part. […]
the number of molding cycles is up to 100K, used to a low volume of plastic parts. Mold materials do not have to be highly wear-resistant. […]
