Rubber Molded Product

Use of Rubber Products
Rubber products are usually divided into three Main Categories: (1) tires,
(2) Industrial rubber goods used in motor-vehicle, aircraft, and ship construction, agricultural machine building, railroad transport, and construction, and
(3) consumer goods, including footwear (the most important in this category), mats, bathing caps, inflatable inner tubes and rubber rings, gloves, and pacifiers.
Most rubber products are made from hard raw rubber, although some are made from latexes, for example, seamless gloves with thin walls, rubber thread, and foam-rubber seats for automobiles and furniture.
Rubber Molded Products
Rubber molded products refer to a diverse group of vulcanized rubber products which are manufactured in a mold and the desired size and shape is obtained. Molded rubber products include diaphragms, vibration isolation devices, air springs, bushings, and all kinds of pads, boots, wiper blades, chassis bumpers, fascia, conveyor wheels, grommets, and more. They are used in a wide range of services.
 Shrinkage
This is the difference between corresponding linear dimensions of the mold and of the molded part. All rubber materials display some amount of shrinkage after molding when the part cools. The mold designer and the compounder must measure the amount of shrinkage and which is incorporated into the size of the mold cavity. Even though the mold is built to anticipate shrinkage, there is always an inherent difference which must be covered by adequate dimensional tolerance. Complex shapes in the Rubber Molded Product may restrict the lineal shrinkage in one direction and increase it in another. The rubber manufacturer always aims at minimizing these variables, but they cannot be eliminated altogether.
