Surface Finishes for Overmolding
Improve the quality of your overmolded parts with excellent surface finishes. NOBLE offers a long list of surface finishing options to improve the cosmetic quality of your products. We provide exceptional secondary operations to improve the overall quality of products.
Glossy
A grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.
Semi-glossy
B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.
Matte
C grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.
Textured
D grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.

Overmolding FAQs
Overmolding is a manufacturing process in which a substrate or pre-existing part is encased in a second material to create a composite part with improved functionality, aesthetics, or durability. The process typically involves two or more stages of injection molding, in which the substrate or first material is molded first and then a second material is molded over it.
Traditionally, overmolding involves placing a part formed in one tool/machine into a second tool to mold a second material over the original part. The result is a part with a strong bond between the two materials. Modern overmolding is now called 2K or overmolding.
Traditionally, overmolding involves two injections of material to form the substrate and overmolding. Insert molding involves only one injection of molten plastic, but metal inserts need to be purchased or fabricated separately.
According to NOBLE’s more than ten years of experience in injection molding, the thickness of the overmolding material should be less than or equal to the thickness of the substrate below it, and at the same time, the melting temperature of the overmolding material should be lower than that of the substrate. Of course, chemical bonding of overmolded materials is not feasible or successful.
Based on the overmolding experience of NOBLE engineers, the overmolding design needs to pay attention to the following two major matters: 1. The wall thickness of the base material and secondary molding should be as uniform as possible to obtain cycle time. 2. Wall thickness should be controlled within the range of 0.711 to 3.81 mm to ensure good adhesion in most overmolding applications.
Overmolding is a manufacturing process that involves molding one material over another to create a composite part with improved functionality, aesthetics, or durability. The process typically involves two steps:
1. First, a substrate material is molded into a specific shape using injection molding or another molding process. The substrate material can be made of metal, plastic, or any other material that can withstand the molding process.
2. Next, a second material, called the overmold material, is molded over the substrate material to create a composite part. The overmold material is chosen for its compatibility with the substrate material, its mechanical properties, and its processing characteristics. The overmold material can be a thermoplastic or thermosetting material, depending on the specific requirements of the application.
