Insert molding is a unique manufacturing method that allows manufacturers to integrate plastic or metal inserts into a molded component. Insert molding supports a range of design options while offering enhanced functionality and superior durability.
RD Rubber is a leading insert molding service provider with over 35 years of experience delivering quality products. We offer custom solutions for demanding applications, leveraging sophisticated technology and deep expertise to realize high-quality products. We are known for delivering superior solutions and satisfying customer experiences in the manufacturing industry.
What Is Rubber Insert Molding?
Rubber insert injection molding delivers a superior bond between components. In this process, metallic or other heat-resistant materials are encapsulated with bonded rubber to produce a single integrated component. Rubber insert molding is ideal for creating complex parts with greater structural integrity.
The manufacturer puts the heat-resistant inserts into the mold before encapsulating the inserts in a rubber material. They then cool the molding and visually inspect the finished product.
The Insert Molding Process
Rubber insert molding follows several steps, including:
- Engineering and material selection. We work with you to engineer a superior manufacturing process, selecting the ideal material for your project requirements.
- Mold preparation. We create a mold that accommodates the insert and allows for precise injection.
- Insert placement. We position the insert within the mold, ensuring its secure placement throughout the rubber injection process.
- Injection molding. We inject rubber or plastic into the mold to form the desired shape before curing the finished product.
Insert Molding vs. Overmolding
Overmolding and insert molding both combine distinct materials. However, there are several differences to consider when choosing one of these methods for use in a manufacturing project:
- Insert molding delivers superior durability and strength by integrating the insert with the injected rubber or plastic material
- Overmolding produces an additional layer of molded material over an existing component
- Insert molding is preferred for producing integrated components with improved durability
- Overmolding is a superior solution for introducing secondary features to a component, offering a flexible option for a breadth of manufacturing projects
The Unique Benefits of Insert Molding
Insert molding delivers several notable benefits, including:
- Improved product durability and strength (due to its integration with different materials) for a robust and solid finished product
- Lowered manufacturing labor costs with rapid assembly time and reduced additional component requirements
- Increased flexibility, which can be leveraged to create multifunctional parts and complex geometries for various project requirements
- Enhanced assembly process that produces a single integrated product, increasing efficiency while reducing labor costs
