What is Overmolding?

Overmolding is an advanced manufacturing process that combines two or more materials to create a single, cohesive product. By molding a layer of material (typically a softer, flexible material like rubber or TPE) over a base component made of a harder substrate such as plastic or metal, overmolding enhances the functionality, aesthetics, and durability of the final product. This innovative process is widely used across industries such as automotive, consumer electronics, medical devices, and industrial applications to deliver superior product performance and user experience.

At XC Machining, we specialize in providing top-notch overmolding services tailored to meet the unique needs of our clients. Our advanced capabilities and commitment to precision ensure that your products are manufactured to the highest standards of quality and functionality.

Surface finishes for Overmolding

We offer finishing services for Overmolding, providing a wide range of finishing options to enhance both the durability and appearance of your parts. Whether it’s for prototyping or full-scale production, our finishing solutions ensure that your parts meet the highest standards of performance and visual appeal for all needs.

Brushing is a technique that utilizes abrasive pads or brushes to add a finish to the surface of a material. It is commonly used on metal surfaces to enhance their visual appeal. This method is especially effective on stainless steel, creating either a linear or circular pattern on the surface.

Black oxide coating is a popular choice for enhancing the surface of steel and iron. This finish not only provides a visually appealing dark surface, but also offers excellent wear resistance. Additionally, the black oxide coating can enhance the lubricity and durability of the treated surface, making it an ideal option for various applications.

Passivation is a common process used to enhance the corrosion resistance of stainless steel by removing iron impurities and forming a protective oxide layer. This helps to improve the durability and performance of stainless steel in tough environments.

Paint serves as a surface coating that is effective on a wide range of materials, offering both aesthetic enhancement and protection against corrosion. It is available in numerous color options, making it suitable for application on metals, polymers, wood, and various other substrates.

Enhance the shine and smoothness of your materials by utilizing polishing techniques. By using abrasives such as buffing wheels or polishing chemicals, you can elevate the reflectivity and overall aesthetic of metals, resulting in a stunning mirror-like finish.

Alodine coating, also known as chromate conversion coating, is widely used on metals like aluminum. It serves as an excellent primer for paint or powder coatings, providing a durable and corrosion-resistant finish. By creating a thin layer of protection, it enhances the bond between subsequent coatings, ensuring long-lasting results.

Brushing is a technique that utilizes abrasive pads or brushes to add a finish to the surface of a material. It is commonly used on metal surfaces to enhance their visual appeal. This method is especially effective on stainless steel, creating either a linear or circular pattern on the surface.

Anodizing, a commonly used surface treatment for aluminum, creates a protective oxide layer on the metal’s surface. This not only enhances the durability and corrosion resistance of CNC machined parts but also adds to their visual appeal. Moreover, anodizing offers various options for coloring, making it an ideal choice for enhancing the overall aesthetic of the material.

Powder coating is an exceptional dry finishing method that utilizes electrostatic application of fine powder onto various surfaces. Once applied, the curing process takes place to guarantee a permanent treatment. With its remarkable ability to withstand impact, solvents, and UV radiation, powder coating provides an enduring and superior finish. From metals to polymers and even wood, there is a wide range of materials that can benefit from the protective coating of powder.
