Rubber Seals
Rubber seals, sometimes referred to as rubber gaskets, are used to join mechanisms in order to prevent leakage and to aid in compression. Unlike wax or metal seals, rubber seals will expand and contract in order to fill the space for which it is designed. Rubber seals are available in a variety of shapes and sizes.
Rubber seals are ideal in situations that require the material to give and return to its original shape. While there are variations in specific rubber molding methods, all rubber seal manufacturers use heat and pressure to form the seals. The three most common methods used in rubber molding are injection molding, compression molding, and transfer molding. Although the particulars of the methods vary, all three involve pouring liquid rubber material into a mold, where it is cured in an oven and cooled into the finished product.
Some of the specific industries that benefit from rubber seals include the automobile, appliance controls, lawn and garden, sporting goods, medical, electrical, government, and recreational industries.
