发明名称 Method of molding using an inflatable seal
摘要 The invention is a mold adapted for forming a member from a thermoset or thermoplastic resin about a substrate at a distance from the end of the substrate without leaking of the thermoplastic or thermoset material onto the portion of the substrate between the end and the starting point of the member being formed about the substrate, wherein the mold comprises (A) a mold casing adapted for forming a member from a thermoset or thermoplastic material about a substrate at a distance from the end of the substrate, (B) an inflatable seal adapted for forming a seal about the substrate when inflated at a distance from the end of the substrate such that the thermoset or thermoplastic material is contained to the area of the substrate about which the member is to be formed, (C) a means for inflating the seal such that the seal can form a seal about the substrate at a distance from the end of the substrate. This invention further relates to a method of using such a mold to form a member from a thermoplastic or thermoset material about a substrate at some distance from the end of such a substrate. The novel mold and method of this invention allows the formation of a member from a thermoplastic or thermoset material about a substrate at a position some distance from the end of a substrate.
