Overmolding is the process of molding a second layer of plastic around a pre-formed component, often for ergonomic or protective purposes.
Sanding smooths the surface of overmolded parts, especially where there’s a seam or excess material, ensuring a uniform finish and a comfortable grip in consumer goods.
Polishing is used to improve the appearance of overmolded components, particularly on high-visibility areas, giving the part a smooth, glossy finish that enhances aesthetics.
Texturing creates a matte or grippy surface on overmolded parts, improving tactile feedback and preventing slipping, commonly applied to tools or ergonomic handles.
Anodizing is applied to metal inserts in overmolded parts to provide corrosion resistance and an aesthetic finish that improves longevity in harsh environments.
Brushing is used for metal inserts in overmolded parts, giving them a uniform, matte finish that reduces reflection and improves the part’s durability and appearance.
Vibratory finishing is ideal for overmolded parts with intricate geometries, smoothing out the plastic surface and removing any excess material left after the molding process.

How does overmolding impact the function of electronic components?
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.
What are your strategies for minimizing waste in overmolds?
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.
How can overmolding help meet regulatory standards?
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.
Do you offer finishing services for overmolded parts?
Yes, we provide comprehensive post-processing services such as machining, painting, and texturing to improve both the functionality and aesthetics of overmolded parts.
What’s the impact of overmolding on assembly time and costs?
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.
