RUBBER TO METAL BONDED COMPONENTS – CRITICAL TO SEVERAL INDUSTRIES

Rubber to metal bonding or adhesion is a very common practice in several industries since such processes are required for various applications. Be it for sticking silicone parts or rubber parts to hard or very hard metal parts, the adhesion processes used in rubber to metal bonding is same but with varying levels of adhesion. Rubber to metal bonded products are especially prevalent in the automotive and engineering industries, wherein such processes help to insulate noise and offer protection to the components. There are essentially three components of any rubber to metal bonding.

  • Rubber
  • Bonding agents
  • Substrate

In certain components, adhesion is required only for assembly purposes whereas others require very close controls. The levels of adhesion required for any rubber to metal bonded component depends upon the following factors:

  • Type of application intended
  • Types of metal
  • Preparation of surface
  • The number and types of nonmetallic inserts
  • Conditions of curing
  • Type of adhesive used 

The processes of rubber to metal bonding generally include:

  • Preparation of the surface to be bonded by cleaning it thoroughly
  • Preparation of inserts by methods of blasting or degreasing
  • Vulcanization of the prepared inserts for obtaining the desired adhesion

More commonly, adhesive cements are used for rubber to metal bonding. The adhesives used for such bonding are either solvent based or water based. Solvent based adhesives are low on hazardous air pollutants. It is important that the adhesive for each of the applications be chosen keeping in mind the rubber materials and the metals used in the process. It is also to be remembered that the adhesive chosen should be able to withstand the potential use and wear and tear of the components that are to be bonded. Adhesives are available both in single coat and double coat system, each catering to specific needs. Two coat systems are generally used in instances wherein the component is used in harsh conditions.

RUBBER WASHER – GET TO KNOW ALL ABOUT IT

Image
Rubber in its various avatars, both natural and synthetic, is used for creating different components for industrial applications. Every rubber material comes with different characteristics. These characteristics determine the components that a particular rubber material can be used for. Rubbers and its various compounds are widely used for creating washers. Washers act as gaskets around bolts and are used in applications that involve high compression. Rubber washers are created from molded rubber. Although washers are made from metal too; however rubber washer ismore popular as compared to its metal counterpart. Rubber washer is more resistant to fluids and it does not rust like metals. Rubber washer is flexible and it is because of this reason that it is widely used in applications that require constant expansions and contractions. Rubber washer can stand the test of time even in very heavy duty applications.One of the main tasks of rubber washer is to prevent leakages by creating

Rubber bush manufacturer

Image
Rubber bushes are usually found to have cylinders bounded to their outer regions and their inner regions have rigid metal layering. Bushes are used for taking up radial or axial road and torsional movement. Bushes can also be utilized for regulating conical deflection. Bushes are made up of different materials and come in various sizes. Rubber bushes are usually made up of natural rubber (which is also called poly-isoprene) of varying grades and alternative synthetic rubber (elastomers). The bushes are usually pressed into any place or a loosely fitted assembly. A rubber bush manufacturer supplies simple, laminated, pivot, spherical, flanged, void, suspension, torque arm, conical, and equalizer bushes. The rubber bushes are manufactured through a specific process. Almost every rubber bush manufacturer adopts the following process for making rubber bushes. Preparing and collecting rubber compounds according to the individual requirements of each client. Gathering material

Rubber Cap –Helping to Plug Gaps Perfectly

Image
A rubber cap as the name suggests, is a cap or a plug made up of rubber. A rubber cap is essentially used for plugging gaps in a variety of applications that involves high heat and highly reactive chemicals. These caps are popularly used in powder coating and medical sterilization applications. These are also used in furniture, gadgets and any equipment that may require high level of protection against fluids and temperature. Rubber cap are more commonly used in applications that need very tight closures. These caps offer a high level of noise insulation too. Rubber caps are very long lasting since they can withstand a high range of temperature, highly reactive chemicals, wear and tear, and corrosion. Rubber caps are available in more than 350 varieties of polymers, but out of all the varieties, the following three are the most important. ·          EPDM rubber caps: EPDM rubber caps are generally used in applications that involve harsh chemicals. They can withstand high levels t
