We offer versatile surface finishing options for CNC Milling Services to improve part functionality, appearance, and durability.
Achieved through fine polishing of the mold, this finish provides a clean and sleek appearance, ideal for products requiring a glossy surface.
This finish creates a tactile surface, improving grip and enhancing the product’s aesthetic appeal. It’s often used in products like tools or automotive components.
Offering a non-reflective surface, matte finishes help reduce glare and are often chosen for products with a modern, subdued look.
A highly reflective finish that gives parts a shiny, polished appearance, often used for high-end consumer electronics and cosmetics packaging.
This type of finish provides a smooth, velvety feel to the product, often used in consumer goods such as handheld devices for an enhanced user experience.
A custom pattern is added to the surface, offering both aesthetic value and functional benefits, such as preventing slippage on grips or buttons.

We carefully control temperature and pressure during overmolding to prevent damage to electronic components. The insulation properties of overmolding materials also safeguard electronic functionality while enhancing durability and aesthetic appeal.
We focus on material and design optimization early in the prototyping phase, use simulation software to reduce trial errors, and recycle compatible materials to cut costs and minimize environmental impact.
Overmolding can add materials that are non-toxic, biocompatible, or flame-retardant to enhance compliance with industry standards, ensuring the finished product exceeds safety and regulatory requirements.
Yes, we provide comprehensive post-processing services such as machining, painting, and texturing to improve both the functionality and aesthetics of overmolded parts.
Overmolding can reduce assembly time and costs by integrating multiple components into a single part, reducing the need for additional fasteners and assembly steps. This streamlined process can lead to significant savings in both production time and costs.
