Injection Molding with Insert Molding | HRB Industries

Insert molding is a more advanced molding process that seamlessly joins traditional injection molding with modern technologies to create complex, high-quality products that combine multiple materials into a single integrated component. This process is widely used in industries such as automotive, medical devices, consumer electronics, and industrial equipment, where the combination of metal inserts with plastic overmolding enhances structural integrity, electrical conductivity, sealing performance, and overall product functionality.

At HRB Industries Corporation, we leverage years of expertise and advanced facilities to provide the finest insert molding services in the industry. Our process begins with the design of the mold, where we work meticulously to ensure that the first phase captures the specific inserts required for each project—whether they are threaded inserts, metal contacts, bushings, or other embedded components. Our engineers carefully design the mold geometry to securely position and encapsulate the inserts, ensuring strong mechanical bonding and precise alignment.

After the mold is finished, we individually use state-of-the-art injection molding machines to inject liquid plastic around the metal or other inserts. The molten material flows around and through the inserts, forming a strong, durable bond that improves the final product's performance and longevity. This process eliminates the need for secondary assembly operations, reduces part count, and enhances product reliability.

Quality assurance is our guiding principle. An in-house control system is utilized in conjunction with rigorous testing protocols to create a safe and controlled production environment. Each component is validated through dimensional inspection, adhesion testing, and functional performance checks to ensure it meets our stringent quality assurance policies.

Being ISO 9001:2008 certified means that we are able to provide clients with products we are confident will surpass their expectations. Our emphasis on quality, combined with our technical expertise and responsive service, has made us a leading partner for OEMs across multiple industries. At HRB Industries, insert molding is not just a process—it is a solution that enhances product value and customer satisfaction.
