Industry Information
Bonding rubber to metal to produce metal and rubber products involves gluing rubber to metal by way of various adhesives. A mold is also used to give the rubber a certain shape when the rubber is bonded to the metal. While steel was originally the most common metal to use, today aluminum bonding is popular because it saves on both cost and weight without compromising the product's quality or seal strength. Metal bonding is used to fabricate products for many different applications within the automotive, aerospace, construction, plumbing, electric, industrial machinery, vibration absorber and medical industries, as well as rubber roller manufacturers. Silicon bonding is mostly used to make surgical instrument handles as well as other products including rubber lined rollers, engine mounts, gaskets, reinforced tires, bearings, rubber lined tanks/pipes, conveyor belts, electrical cables and plugs. Rubber bonding can take place with materials other then metal, although bonded metal is the most well-known, since all grades of steel, aluminum, copper, beryllium and brass adhere to bonded rubber. Glass, fabric and a variety of plastics are also utilized. However, the metal must be able to handle the high heat and pressure involved in the bonding process. The rubber material can be natural or synthetic, and includes silicon, neoprene and nitrile. 

In the rubber metal bonding process there are three main components: the rubber material, the bonding agents and the metal substrate. Any type of rubber can be used, providing that the material can flow into the mold without developing a significant level of cross-linking and that the substances making up the rubber material will not bleed rapidly to the surface of the uncured stock. The bonding agents consist of solutions based on solvent or water, with a primer coat based on phenolic-style resins and a topcoat of polymers and other materials. If the part will not be exposed to high heat, humidity or pressure, sometimes a single coating of bonding adhesive will work. Most of these solutions are patented. The thickness of the bonding layer depends on the nature of the rubber formulation. The application of the bonding agents typically requires the spraying of a gray primer coat over a slightly wider area than the black topcoat, using a low pressure, high volume barrel spraying machine. Before the substrate can be coated in adhesive, it must be cleaned well of all dust, grime and oils leftover from the fabrication process. The specific type of adhesive material is determined by a couple of different factors; the operating conditions of the finished part and the rubber and metal chosen as the materials.

The science behind the rubber metal bonding process is varied and complex; rubber to metal bonding is often referred to as a sophisticated industrial process because it takes both skill and patience. Often the type of polymer (rubber) chosen depends on what type of metal is to be used and/or the part being manufactured. Determining the appropriate bonding agent is critical. The selection process depends on the rubber to be used, the component design and the elasticity of the rubber. The traditional metal used in rubber metal bonding services is steel in all its forms and grades, but recently, an increasing amount of products are made of aluminum alloys and polyamides because they are less expensive and lighter in weight without compromising quality or durability. Almost any material can be bonded to rubber, provided that it can withstand the heat and pressures of the rubber molding process. However, the results of bonding rubber to alloys, such as bronze and brass, greatly depend on the composition of the alloys. Environmental factors have also changed the bonding material. Originally, solvent-based adhesives were used, but today they have mostly been replaced by water-based adhesive, an environmentally friendly alternative that has been proven to provide the same sealing properties that are able to withstand the same conditions and last just as long.

The bonding process, no matter what type of metal, bonding adhesive and rubber are chosen, is similar in almost all cases. After the substrate has been fabricated, it must be cleaned of all dust, debris, grime and oil using a sand blaster, chemicals and degreasers. Next, the bonding agents are sprayed onto the surface in coats. The rubber molding process is next, which is considered the most important and difficult step in the bonding process. The metal component is positioned within a mold, which is most likely injected with uncured rubber that is heated and almost molten. Sometimes, plated inserts are added for more strength. The rubber is left to cure, and when it has completely dried, the part is finished. Sometimes the mold itself is just slightly larger than the substrate, and the rubber forms a thin coating around the metal, while other products require complex rubber part designs that greatly differ from the substrate's dimensions. The products made by rubber metal bonding services are used in various areas of the industrial, commercial and medical fields. Many of the components are used for the isolation of vibration and noise in manufacturing applications. The motor vehicle industry in particular uses a large number of bonded rubber to metal parts. The steering wheel is joined to the steering column by various rubber bonded parts. Foot pedals and bumpers are examples of common items that have rubber/metal characteristics. Because of the wide variety of parts used today consisting of bonded rubber to metal, most of the shops that specialize in the manufacturing of these parts are custom shops that work with customers from the design level through production.
