The term “gasket” is used throughout the industry and refers to a wide range of products. When we encounter customer drawings labeled as a gasket, we can categorize them in one of two ways, related to the best means to manufacture the part: they’re either molded or die-cut. These are two very different manufacturing methods, each with their own unique characteristics.
A gasket fills the space between mating surfaces, and is then compressed to prevent leakage. Simple. Understanding the end-use application environment will guide the selection of the best part.
Die-cut gaskets are made from a sheet or roll of material in a specific thickness. A steel-rule die cutting tool is made from the mechanical drawing and parts are stamped out of a press one after the other. There may be secondary operations required on some parts but for the most part, the die-cut parts are ready to use as they come off the press.
Molded gaskets are manufactured in typical environments, where most molded rubber components are made. They are compression, transfer, or injection molded from uncured rubber compounds in custom-built mold tools, and cured under heat and pressure.
