Rubber-to-metal bonding is a great option for items that need metal stability but rubber’s flexibility. Rubber becomes incredibly strong and long-lasting when linked to metal. These properties are crucial in situations with noise, vibration, and harshness. Rubber-to-metal bonding creates dependable, personalised isolators for machinery. Manufacturers have the flexibility to choose the elastomer and metals to be bonded. Each material has unique qualities, such as temperature resistance, robustness, and more. Read More…

More Bonding Rubber to Metal Manufacturers
Rubber is attached to metal inserts in the mold during the molding process. The metal components are sprayed with a heat-activated adhesive before being placed in the mold. In many cases, the resulting bond is more powerful than the elastomer.
Different Rubber and Metals That Can be Bonded
Rubber materials or polymers can be joined with metal in various ways. Depending on the qualities they need, manufacturers select a polymer. For instance, a producer may use silicone if they require a flexible polymer. The six most frequently used in metal rubber bonding are natural rubber, fluoro-elastomer, ethylene-propylene, nitrile, neoprene, and silicone.
There are numerous metal choices as well. Manufacturers will select certain metals depending on how the rubber component will be used. Aluminum is a good option for manufacturers looking for cheap, robust material; however, steel, brass, beryllium, and copper are also frequently used.
Rubber to Metal Bonding Process
Metal inserts are prepared using degreasing equipment to clean off contamination. Next, heat-activated glue is sprayed on the metal inserts using a method similar to spray painting. After processing, the metals are inserted one by one into each mold cavity. Special magnets are built inside the mold to hold inserts in place while the mold is being loaded.
When an insert is encapsulated in the rubber, special chaplet pins will suspend the insert. Rubber can then encapsulate the metal. The rubber molding procedure starts after the metal inserts are in place. The metal adhesive is activated after the mold is sealed and molding starts, which enables the metal to adhere to the rubber.
Rubber to Metal Bonding Methods
Encapsulation
Encapsulation is also referred to as "insert moulding." Before the rubber is added, a metal insert will be put in a mold to complete encapsulation. As a result, a portion of the finished product will have hardly noticeable metal. This process is frequently used to create components like o-rings that use wiring.
Over-molding
Overmolding is when rubber is molded on a metal substrate. Both the rubber and metal will be visible in an over-molded item. This enables manufacturers to produce additional rubber and metal layers as necessary. One of the most frequently over-molded elements is a seal.
Transfer Molding
In transfer molding, metal parts are placed manually into a heated mold. The transfer mold's well pot is then loaded with material. The rubber is heated when the mold shuts, then transmitted through the runner—the gate sprues around the metal insert and into the mold cavities. The pressure and high temperatures cause the rubber to cure and vulcanize, allowing pieces to be removed. The transfer molding process has numerous advantages. First, tools cost less than injection molding machinery. It works well for complicated shapes. Finally, it takes less time to produce than compression molding techniques because of its reduced flash.
Injection Molding
Injection molding is a process that is also used in this approach of rubber-metal bonding. A metal item is first placed into the mold. The mold is then filled with a liquid elastomer. After the mold has undergone high pressure, temperature curing, and vulcanization, the portion is removed from the mold. Injection molding allows for quicker manufacturing times and is suitable for large quantities of goods.
Benefits of Rubber to Metal Bonding
After rubber-to-metal bonding, fewer components are needed during assembly. Fewer components are required because the rubber is directly connected to the substrates. Rubber-to-metal bonding optimizes the assembly process, creates materials with a longer lifespan, and creates corrosive-resistant substrates. The rubber-to-metal bonding can withstand a wide range of temperatures, enabling the bonded materials to be used under demanding circumstances without harm.
Choosing the Proper Bonding to Rubber Metal Company
To make sure you have the most positive outcome when selecting a bonding to rubber-metal company, it is important to compare at least 4 companies using our bonding to rubber-metal directory. Each bonding to rubber-metal company has a business profile page that highlights their areas of experience and capabilities and a contact form to directly communicate with the company for more information or request a quote.
