Fabric Over-molding
In Fabric Over-molding, also sometimes called "back molding" or "in-mold decoration" (IMD) processes, finished decorated parts are produced by inserting film or fabric products into the mold. Apart from decoration or lettering, surface texture and deep gloss can also be generated.
Visual and tactile appeal, enhanced by molded-in fabrics, is increasingly important to markets such as consumer electronics. During the process, fabric is placed in the mold and over-molded to become one with the plastic. Fabric overmolding can also "open the door" to improved functionality. For example, overmolded layers can act as gaskets to provide a water-tight seal.
The main benefit of fabrics over-molding is the integration of two formerly separate and sequential manufacturing steps into a single operation, saving on manufacturing costs. Furthermore, flexibility is gained as the decorative finish of the parts can be changed without interrupting production by using different films from one shot to the next.
