摘要: A shim for a compression mold for manufacturing a component from reinforced plastic, typically from SMC, comprising a fixed molding element, a mobile molding element, and a mobile shim that can be moved by an actuator. The mobile shim comprises a conventional part made of steel but also a part made of a high expansion material with a mean coefficient of expansion that is high enough that its own expansion at the molding temperature places the shim in compression against the molding element and seals against this element, thus eliminating flash on the molded part. This material is advantageously a polyetheretherketone, or PEEK. A mold comprising this shim and a compression molding method are also disclosed.
