Abstract
A method for producing a carpet mat by injection molding, includes providing an injection mold including a cavity and a complementary core, each defining a portion of a mold recess for accommodating the finished carpet mat, providing the cavity with a surface having at least one vacuum opening bordered by a peripheral retaining barrier, applying vacuum to the core, inserting a sheet of carpet into the recess of the cavity and against the surface so that the carpet is in contact with the cavity, so that the carpet is held in the recess by the vacuum. Next, the cavity and core are closed together, thus sealing the recess, and a flowable supply of plastic is injected into the recess. Finally, the mold is opened after a specified period, allowing the plastic to at least partially solidify.
