An injection molding process by which the characteristics of a product may be controlled by molding the product of two or more dissimilar melts by simultaneous injection of the dissimilar melts into the mold in such a manner that the dissimilar melts intermix at transitional zones to provide a one-p

대표청구항 ▼

An injection molding process comprising injecting a primary melt composition into a mold channel perimetrically surrounding a mold cavity thereof, introducing said primary melt composition, under positive pressure, into said mold cavity from said channel at a plurality of points lying in a plane bisecting said mold cavity, simultaneously injecting a predetermined quantity of at least one secondary melt composition into said mold cavity at a point having a linear projection normal to a plane bisecting saiD mold cavity, said primary and said at least one secondary melt compositions being characterized by at least one dissimilar property, controlling said injection of said at least one secondary melt composition into said die cavity so as to promote formation of an island thereof within said primary melt composition, controlling said introduction of said primary melt composition into said mold cavity so as to permit said primary melt composition to intimately mix with a continuous peripheral portion of said island of secondary melt composition for thereby promoting formation of a transition zone therebetween and setting said primary and secondary melt compositions and said coalescent transition zone therebetween within said mold cavity so as to form an injection, integrally molded/plastic article of unitary construction exhibiting specific preselected properties at predetermined areas thereof.
