Rubber Manufacturing

Rubber is an elastomeric material of which there are two main types: natural rubber and synthetic rubbers such as neoprene, silicone, EPDM and styrene. Rubber companies provide rubber parts or components and offer rubber forming services. The two main services that rubber manufacturers offer are rubber molding and rubber extrusion. In fact, industrial rubber molded products are extremely popular and include rubber diaphragms, rubber grommets and rubber washers. Many industrial rubber products undergo secondary rubber manufacturing services to fit unique applications, such as a rubber baseboard being die cut to fit an exact wall size. Rubber manufacturing is essential to many different industries including the chemical processing, construction, automotive, electronics, medical, petrochemical, and aerospace industries. These industries use fabricated rubber products in essential applications like sealing, insulating and vibration absorption.

Types of Rubber Manufacturing:

Polyurethane Molding

Polyurethane is a very versatile material and can take many different forms. These materials exhibit many properties of rubber, plastic, and metal, but it typically lasts longer than plastics and is more resistant to impact than rubber. There are two main ways in which polyurethane is molded. Open casting involves pouring a mixture of liquid raw materials into a mold which is then cured to form the final product. Closed casting is similar except that the mixture is injected into a pressurized cavity. Depending on the raw materials used, polyurethane can be more elastic or more rigid for a variety of applications.

Rubber Extrusions

The rubber extrusion process allows different rubber materials to be shaped into useful products. Products like weatherstripping, rubber seals, rubber grommets, and rubber bushings are all results of the rubber extrusion process. Extruding involves pressing rubber through a die which shapes the rubber and cuts away material, leaving a rubber profile. The dies can be designed to produce almost any shape imaginable, so rubber extrusions can be custom made to satisfy a diverse range of requirements.

Rubber Molding

The rubber molding process differs from other rubber shaping processes through its use of molding cavities. Before the rubber can be shaped, it must first be melted. The melted rubber is then poured into a mold where it solidifies, taking the shape of the cavity. The cavities used in this process can be customized and designed to produce much more complex and irregular rubber shapes than other rubber forming methods. Some common molded rubber products include washers, grommets, and seals.

Rubber Rollers

Rubber rollers are generally comprised of a cylindrical metal core surrounded by a rubber tube which creates a semi-elastic rolling surface. These rollers are used extensively in many industrial settings, and they are perfect for printing and transportation applications. Some common rubber rollers include ink rollers, drive rollers, guide rollers, and conveyor rollers. Additionally, the rollers can be fabricated from a variety of rubber materials such as neoprene, EPDM, nitrile, and silicone, so these rubber rollers can meet the needs of many industries.

Rubber to Metal Bonding

Rubber is bonded to metal using a variety of different adhesives. A metal substrate is sprayed with the bonding agent and then placed inside a mold. Rubber is then injected into the mold and allowed to cure, and once the rubber has solidified the part is complete. The process is used to fabricate products like rubber rollers, gaskets, seals, electrical cables, and engine mounts, and these kinds of products are utilized in the construction electric, medical, automotive, and aerospace industries.


Foam is a low density material comprised of polymer materials with air bubbles trapped inside. Fabricating foams involves aerating molten polymer materials which are then allowed to cool leaving small pockets of air within the material. Open cell foam and closed cell foam are the two main varieties of foam. Open cell foam is flexible and soft while closed cell foam is more stiff and incompressible. These materials are used for both industrial and commercial applications like insulation, support, and cushioning.
