The Process of Rubber Molding
authoradmintime2016-05-02
Rubber molding is a molding process that produces a useable rubber product.
Rubber products are made from uncured rubber or elastomers. An elastomer is
any material with sufficient resilience or memory for returning to its original shape
in response to pressure or distortions. Rubber and elastomers can be derived
from natural sources, although they are mostly synthetic, produced through highly
controlled chemical processes.
Rubber is an excellent material for situations that require a material to
expand and return to its original shape. Specific industries that benefit from
custom molded rubber are automobile, appliance controls, lawn and garden,
sporting goods, medical, electrical, government and recreational. These
industries and others benefit from many different products that can be created
with this process.
Rubber molding creates molded rubber parts by pressing a block of rubber into a
Rubber moldingmetal cavity. The rubber is then exposed to heat, activating a
chemical reaction. While there are variations in specific methods, all rubber
manufacturers use heat and pressure method to form molded rubber products. The
three most common methods in the rubber molding process are injection molding,
compression molding and transfer molding. They all involve pouring liquid
rubber material into a mold where it is cured in an oven and cooled. Some
examples of molded rubber parts include rubber grommets, tubes, shock mounts,
stoppers, hoses, bumpers, washers, gasket and seals. Foam rubber goods are also
significant due to their many applications.
