Abstract
This document relates to a molding tool for forming and back-injecting a bendable sheet including a mold that includes a first mold half and a second mold half. The first half is arranged opposite the second half forming a cavity for receiving the bendable sheet and a melt. Further, the mold includes at least one pin for holding the bendable sheet and the pin is retractable in response to a force exerted on the pin by a pressure of the injected melt during back injection.
