The overmolding injection molding process involves adding material (overmold) to a rigid part (substrate) such as metal or plastic to form around it.

To provide your large plastic parts, we focus on the smallest of details. We achieve precise measurements with our large-tonnage presses to ensure your part's form, fit, and function meet expectations. With custom plastic injection molding presses ranging up to 1,500 tons of clamp and over 50 types of resins to choose from, our facilities are specially equipped and designed to handle your large orders from start to finish.

– Overmolding considerably reduces the need for secondary operations by avoiding manual assembly between two molded parts. Operators then have more time to perform other tasks, which lowers production costs.

Thunderbird Molding has the engineering expertise to meet the challenges of producing larger parts. To ensure the success of your finished large parts, our engineers work with you on the right design, the right materials and resins, and the right press to prevent costly freeze-offs and short shots. We engineer molds to complete your custom plastic injection molding project on time, reduce your costs, increase your parts quality, and optimize performance.

– In terms of product durability, overmolding is recommended because its process creates a chemical bond between the substrate and the material called « bonding ». This effect allows to create a better link between a substrate and a material. Bonding replaces gluing or fixing and guarantees optimal durability.

The advantages of this process are multiple. They can be seen both in the production process and in the quality of the final product.
