What is Overmolding?
Overmolding is an advanced manufacturing process that involves molding one material over another to create a single, integrated component. This technique enhances functionality, aesthetics, and ergonomics, making it ideal for applications across industries such as automotive, medical devices, electronics, and consumer goods. With low pressure overmolding, we can achieve greater precision and flexibility, while the overmolding process ensures the optimal bonding of materials for superior performance. Whether using overmolding injection molding or other advanced techniques, we tailor the process to meet the specific requirements of your project, delivering high-quality, durable results.​​​​​​​

Detailed Overmolding Process
Overmolded parts are carefully inspected for defects, ensuring quality before additional surface finishing, if required.
Initial Substrate Preparation
Initial Substrate Preparation​​​​​​​
● The base material (substrate) is produced or sourced. Substrates can include plastics, metals, or other materials.
● Substrates are cleaned and prepared for optimal adhesion to the overmolded material.
Overmold Material Selection

Overmolding vs Insert Molding: While both techniques involve molding over a core material, overmolding injection molding creates a seamless, integrated part by molding a secondary material over a substrate, enhancing functionality and aesthetics. Unlike insert molding, which inserts pre-formed components into the mold, overmolding offers more flexibility and design possibilities.
