What multi-material overmolding techniques combine PVC with rubber seals?

Multi-material overmolding techniques are essential for creating durable and functional components, especially when combining PVC with rubber seals. One common method is two-shot injection molding, where PVC is first molded, followed by rubber in a second shot, ensuring a strong bond. Another approach is insert molding, where pre-formed rubber seals are placed into a mold before PVC is injected around them. Adhesive bonding is also used, applying specialized adhesives to enhance the bond between PVC and rubber. Additionally, co-injection molding allows simultaneous injection of both materials, improving efficiency. These techniques ensure reliable seals for industrial, automotive, and medical applications, offering flexibility and durability. Proper material selection and process control are critical for optimal performance.
