Overmolding is when a material being is molded over a second material.
The base layer is molded first and the additional plastic layer(s) are molded over and around the original part-resulting in a single, finished product.
To avoid plastic molding defects like distortion, gaps and stress fractures, mold must be meticulously designed and the overmolding process must be performed with utmost precision
Whether you are using metal or plastic resins, proper material selection is critical to ensure material bond together chemically and mechanically without experiencing molding defects like melt or distortion.
