Rubber Molding: Different Choices for Different Applications

If you find yourself in need of the benefits only available through rubber products, then you need to know a bit more about what’s possible through rubber molding.

The molding process can be used to create almost any type of part or component, from very small pieces to enormously large ones. From insulator pads to strip mounts, cylindrical isolators, conical isolators, feet and bumpers, to torsional mounts and everything in between, rubber molding is capable of creating a solution to meet your particular needs.

Types of Rubber Used

However, there are two primary considerations in the realm of molded rubber – natural rubber and neoprene. Both offer vibration dampening and control, as well as slip resistance and other benefits. On the other hand, these materials are not ideal for the same applications.

For example, natural rubber should not be used in applications where the temperature will reach more than 150 degrees Fahrenheit. In addition, natural rubber will begin to degrade and breakdown if it is immersed in oil. If your application does not require the rubber to be immersed in oil and has a lower operating temperature, then this material can be an excellent choice.

Neoprene is a bit tougher than natural rubber, at least when it comes to heat and oil resistance. Neoprene is capable of withstanding temperatures up to 180 degrees Fahrenheit, and resists the corrosive effects of oil, as well. Obviously, temperature and oil resistance are both very important qualities, whether you’re manufacturing a rubber mount for consumer automobiles or seeking vibration control for industrial machinery.

Other Considerations

Of course, finding the perfect material for your rubber molding needs goes a bit deeper than just temperature and oil resistance ratings. You’ll need to know the compression involved in the installation scenario, as well as the disturbing frequency present if creating a vibration isolation product. Rubber molding will also require that you use the correct durometer for your application – the material’s resistance to indentation.

Other considerations when using rubber molding to create custom mounts, pads or isolators include resonance, shear and static deflection, all of which will play a role in creating the best product for your specific needs. Spring rate and transmissibility are also considerations that you need to make.

Finding the Right Firm

In order to make certain that your rubber molding needs are met, it’s advised that you work with a company known for innovation and quality. The right rubber molding firm will be able to help you identify the different requirements for mounts, strips, pads and isolators, and then create a unique design for your application based on those needs and the rubber material that works best for you.

Failing to work with the right molding firm can have damaging repercussions, so making the correct decision here is vital to ensuring the highest quality, best performance and highest longevity possible in your rubber products.
