Surface Finishing of Overmolding & Insert Molding
Injection molding surface finish is critical to a successful part design and it is used for aesthetic and functional reasons in injection molded parts for engineering products. The surface finish improves the look and the feel of a product as the perceived value and quality of the product increase with a suitable surface finish.
Glossy
A-grade finish is smooth and highly reflective, giving the product a shiny appearance. It’s often used for products where aesthetics are important.
Semi-glossy
The B-grade finish is less reflective than glossy but still has a smooth and somewhat shiny appearance.
Matte
C-grade finish is non-reflective and has a dull appearance. It’s often chosen for parts where glare or light reflection is undesirable.
Textured
D-grade finishes are intentionally rough or patterned. They can provide a better grip or a unique appearance to the product.
Overmolding vs Insert Molding
Overmolding process and insert molding process are two specialized injection molding techniques used to combine multiple materials or components into a single molded part. Here’s a comparison and explanation of the two processes:
Molding Cost: Both overmolding and insert molding can accelerate production and reduce assembly costs which generate greater profits for high-volume orders. However, overmolding process may require additional material and labor as it involves two steps, making it potentially more expensive than insert molding process.
Molding Process: Overmolding is a two-step process that involves injecting two-shots of resins to form the substrate and the overmolding. Insert molding is a one-shot injection molding process, but the metal insert needs to create in advance.
Material Compatibility: The overmolding process often involves using different materials with compatible bonding properties. The insert molding process can accommodate a wide range of inserts, including metal, plastic, or electronic components.
Both overmolding process and insert molding process provide unique benefits depending on the application requirements, offering improved functionality, reduced assembly processes, enhanced aesthetics, and cost savings. The choice between the two techniques depends on the desired outcome, design considerations, and specific project needs.
