The term gasket manufacturing refers to the process of manufacturing strong and fully functional gaskets and sealing them with rubber or other seals. Gasket manufacturing, as the name itself suggests, is the production of gaskets from rubber or other suitable materials. It may be a complex process but it’s certainly no rocket science, and many rubber gasket manufacturers have learned to manufacture gaskets by injection molding techniques.
In addition to rubber, gasket manufacturing may be done with other materials such as aluminum, plastic, or other synthetic resins. Most gasket manufacturing involves the manufacture of interlocking seal blocks called gaskets. The blocks are constructed of a solid base made of a strong material (usually acrylic or PVC) and then topped off with a flexible, laminate-type coating that is pressed into place. The sealing top is then finished with a vinyl coating that prevents leaks from water entering the seams of the block. This is a relatively simple process but it must be done accurately and correctly if it’s going to provide the right seal for the product being manufactured.
For example, if a product is to be used for flotation and is in need of a strong seal, then the correct way to do it is to make the gasket blocks out of a strong, waterproof silicone rubber called tribulus terrestris. Then, they should be dipped into a silicone injection mold to create the final round shape. Because silicone rubber has a smooth feel to it, most silicone injection molding companies also use an epoxy resins to adhere the final layer of silicone rubber to the gasket blocks. This technique can also be used to create any number of other shapes, such as triangular, rectangular, circular, or other odd shapes.
