The Rubber to Metal Bonding Process
Over Molding & Insert Molding
The most effective methods for rubber to metal bonding are transfer and injection molding. Here at Qualiform, we will use one of these two processes depending on the components intended application. Rubber to metal bonding is the ideal process for connecting rubber to metal parts. This process can create a wide variety of components including gears, shafts, bumpers, rollers and stops. You can also use this process to bond rubber to brass, plastic, steel and aluminum.
With Qualiform, you also gain the knowledge and expertise of our technical staff. We can help your OEM engineers with component design as well as the selection of optimal rubber materials and compounds. We will analyze the performance requirements of your applications, so we can provide the most accurate recommendations possible. Qualiform’s mission is to give you the quality and uniformity you need with each component. Thus, we offer versatile, custom rubber to metal bonding services for meeting even the most distinct customer requirements.
Two-Step Process for Rubber to Metal Bonding
The rubber to metal bonding involves two crucial steps for the prepping of metal components before bonding. First and foremost, we must remove and clean off any grease or contaminants. This step is also present in preparation for industrial coatings or painting of components. The second step is coating the metal in a heat-activated adhesive.
Once we apply the adhesive, we can begin the over molding process. First, we insert the component into the mold cavity. Magnets hold the component in place during the bonding of specific parts. For rubber encapsulation, however, we use chaplet pins to hold the part. Once the part is secure, we close the mold and begin molding. The high temperatures in the cavity begin to cure the rubber. It also activates the aforementioned adhesive. The mechanical bond begins to form between the metal part and the rubber as a result.

Complete Encapsulation with Rubber to Metal Bonding
Completely encapsulating metal parts in rubber requires a slight modification of the process. We use rubber insert molding instead of rubber to metal bonding, so we can more accurately create the bond. Rubber insert molding involves the suspension of the metal part within the cavity. As a result, we can maintain precision more effectively. This process is also applicable for molding specific areas on a metal part. In this context, insert molding can bond the following materials to rubber: steel, brass, aluminum, alloys, and exotics as well as engineered resins and plastics.
Bonding your components to rubber is an immediate upgrade for part stability regardless of the process. Rubber to metal bonding can implement additional properties into each component. These properties include meeting NEMA standards, conducting electricity, creating environmental seals, isolating noise and vibration, and resisting chemicals and corrosion.

Frequently Asked Questions | Rubber to Metal Bonding
In addition to superior product manufacturing, Qualiform offers dependable customer service for rubber to metal bonding services. We follow up with each client to provide an in-depth explanation of each molding process. As a result, our customers can make an informed decision on the method through which they want to create their parts. For additional questions, please contact our technical staff! Also, look at some of the others of the most common questions we receive below:
How do I get a quote?
To give you an accurate quote, we need a sample or print of the component you want to make. If possible, also include an estimate of your annual usage requirements. This is crucial for tooling design. Next, tell us which material you want to include in your component. However, if you are uncertain of which materials are best, simply describe the conditions of the component’s application. Our expert support technicians can help you identify the ideal material for your component.
Can Qualiform help me design my rubber components?
At your request, we can work with you from the beginning stages of design to final production of your rubber component.
What if I don’t know which materials to use?
We have a team of rubber molding experts who can give you polymer recommendations and help you determine your durometer requirements.
What is the average lead-time for placing an order that requires tooling?
Our lead times vary depending on the type of tooling:
- Prototyping: 2-4 Weeks
- Transfer or Compression Molding: 6-8 Weeks
- Rubber Injection Molding: 8-10 Weeks
If you need a faster tooling lead time, however, we can work with our tooling shop to meet your time restraints.
Is Qualiform tooling manufactured in the U.S.?
Qualiform purchases all tooling from suppliers in the United States, so we can more efficiently complete projects and offer expedited lead times.
What is Qualiform’s lead-time for rubber components?
In most cases, we can ship your rubber components 3-4 weeks after receipt of order. Lead times also depend on the quantity of components.
Can Qualiform use existing tooling?
Existing tooling will work in our presses for the large majority of projects. There is a chance we will have to make minor tooling modifications, however.
Who owns the tooling once I pay for Qualiform’s tooling?
Once you pay for your component(s), you own the tooling. We always customize tooling to every customer’s unique requirements.
Can Qualiform source my metal components?
Qualiform has access to a network of suppliers for the sourcing of metal stamps and inserts for your rubber to metal bonding project.
Can Qualiform match my custom color requirements?
We will work with our rubber resources to produce a color that fits your specifications.
