The Concept of Overmolding in Injection Molding
Overmolding involves injecting a second material onto an existing substrate or component during the injection molding process. The primary material, known as the substrate, provides structural support while the secondary material adds additional features or properties to enhance the final product’s performance.

This technique allows for greater design flexibility by enabling manufacturers to incorporate different colors, textures, hardness levels, or even multiple materials with varying characteristics into a single part. It also eliminates assembly steps that would otherwise be required if separate parts were used.
Remedy by LSR (Liquid Silicone Rubber)
Liquid Silicone Rubber (LSR) has emerged as one of the preferred materials for overmolding due to its unique properties and versatility. LSR is highly durable, resistant to extreme temperatures (-50°C to 200°C), UV radiation, chemicals, and aging effects.
By utilizing LSR in overmolded components, manufacturers can achieve excellent sealing capabilities against moisture ingress or environmental contaminants. Additionally, LSR enables precise control over softness/hardness levels and offers superior biocompatibility suitable for medical applications.
