Abstract

It has been found that when layered preforms are being injection molded utilizing at least two materials, it is possible to maintain the same horizontal and vertical pitch of adjacent cavities as is possible when each mold cavity is being filled with a single material. Most particularly, it has been found that when the percentage of the material to be injected into a mold cavity is relatively high, it is possible to utilize a single metering pot for four adjacent mold cavities. On the other hand, if one of the materials to be injected into a mold cavity constitutes a relatively low percentage of the volume of a mold cavity, it has been found that a small metering pot must be provided for each of the cavities of the four cavity mold. Most particularly, with this combination, it is possible to maintain the pitch of the single material mold and thereby maintain the small size of existing injection systems as opposed to an increase in the pitch of the mold cavities which would increase the size of the mold structure.
