What Is Overmolding?
Overmolding is a specialized manufacturing process in which a secondary material is molded over a rigid base component to create a single, unified part. This method is commonly used to improve grip, durability, protection, and visual appeal. With professional overmolding molding services, manufacturers can combine rigid plastics or metals with softer elastomers or secondary plastics to enhance product performance while reducing assembly steps and long term costs.

Insert Molding vs Overmolding: Key Differences
両方 インサート成形 そして オーバーモールディング are advanced molding techniques used to combine multiple materials into a single component. However, each process serves a different purpose depending on the part’s functional and structural requirements.
| Comparison | インサート成形 | オーバーモールディング |
|---|---|---|
| Manufacturing Method | Pre-formed inserts are placed into the mold before plastic injection | A secondary material is molded over an existing plastic part |
| Main Function | Provides internal strength and functional reinforcement | Enhances surface feel, protection, or appearance |
| Production Steps | Single molding cycle with no post-assembly | Multi-step process requiring multiple molding stages |
| Material Usage | Plastic molded around metal or rigid inserts | Soft elastomers molded over rigid plastic substrates |
| Strength & Durability | High structural strength and long-term reliability | Limited structural strength, focused on surface performance |
| Thread & Fastener Support | Ideal for embedded threads and wear-resistant features | Not designed for threaded or load-bearing reinforcement |
| デザインの柔軟性 | Controlled by insert placement and mold design | Greater freedom for textures, grips, and sealing features |
| Production Efficiency | Faster cycle times and lower labor costs | Longer cycle times due to additional molding steps |
| Common Applications | Connectors, housings, reinforced components, sensors | Handles, grips, seals, protective coverings |
| Best Application Fit | Structural and functional components | Ergonomic and cosmetic enhancements |
