Crescent Industries features in-house overmolding services to support our injection molding capabilities and deliver the widest range of options for our customers. Plastic injection overmolding entails shaping a new form around or over an existing plastic molded form. The process allows for different materials and shapes to be molded closely together without a separate assembly process.

Overmolding provides the benefits of strength, flexibility, protection, aesthetic embellishments, and ergonomics yielded by various materials and forms, while reducing secondary processes and ensuring a tight, permanent fit between the molded components. Below, we will explore the advantages of overmolding before taking a closer look at the process itself.

Benefits and Advantages of Overmolding at Crescent

Plastic injection overmolded parts offers numerous benefits. and is used more frequently in conjunction with standard plastic molding. We are pleased to offer these services to give the following benefits to our customers' products.

  • Ergonomics: Overmolding is frequently used to add features — such as grips and soft plastic touchpoints — to parts that have been molded from harder materials for strength. The ability to mold softer plastic over a harder plastic core provides ergonomic benefits in industries that utilize special instruments and high-touch tools.

  • Multiple material qualities in one part: Overmolding allows for the strength of a harder plastic for core construction with the flexibility and grip of softer overmolded materials.

  • Increased strength and durability: Overmolding can be used to add protective features to corners and other vulnerable sections of components that otherwise may be susceptible to breakage, vibration damage and more. In addition to increasing the durability of the part, these features also provide better safety for operators.

  • Greater design and aesthetic flexibility: Overmolding is often used to add visual identifying aspects — such as color coding — to parts. It can also be used to improve the aesthetics of a product.

  • Reduced assembly time and cost: Overmolding can replace assembly steps that are more time-consuming and costly.
