Tops Precision provides specialized high-quality overmolding services that improve product durability and functionality with visual appeal. Among the wide range of products that need overmolding our advanced techniques combine to deliver precision with superior strength while maintaining performance excellence.
Plastic injection molding via overmolding applies supplemental materials that bond to base substrates to reinforce product features regarding friction control lasting quality and operational capabilities. Through this manufacturing process businesses can integrate different materials into unified products that decrease the amount spent on assembly operations alongside increasing product dependability.
Chez Tops Précision, we offer top-quality precision engineering as well as top technology at the highest levels in providing high-quality overmolding solutions. Onsite they have insert molding, multi-material overmolding, and precision injection molding with seamless material integration for medical, automobile, industrial, and consumer applications. We provide custom solutions with a focus on durability, efficacité, and turnaround for low and high volumes.
This is a process where base material (typically metal or plastic) is placed in the mold and another material (such as rubber or thermoplastic) is injected over it, then it is ‘insert molded’.
Overmolding is the word for when an extra material layer is applied on a present part for better grip, beauty, durabilité, or protection.
In an overmolding context, this means using different materials to over-mold to optimize product performance.
Materials used include:
The precision molding techniques used in overmolding result in strong bonding between materials, accurate dimensions, and defect-free finishes.
Tight tolerances can be achieved due to this, meaning parts fit together perfectly with no excess gaps or material defects.
It guarantees consistency and provides good quality in every batch.
Overmolding is a two-step process a second material is over-molded over an existing part. De l'autre côté, insert molding is a one-step process where plastic is molded around an inserted component. Typiquement, over molding will join hard and soft parts such as plastic over rubber for ergonomic grips, or insert molding will put metal or plastic inserts in to make the object stronger. Insert molding consists of fusing plastic over the insert with or without glue and overmolding requires both to complete the joining process.
If you’re interested in grips, revêtements protecteurs, and soft-touch features, then overmolding is your best option. Insert molding has many applications in threaded components, connecteurs électriques, and metal-plastic hybrid parts.

Here is the table to summarize the design factors required for the over-molding process;
Design Factor | Best Practice | Reason/Benefit |
Sélection des matériaux | Choose compatible materials (par exemple., TPE over ABS) | Ensures strong chemical/mechanical bonding |
Épaisseur de paroi | Maintain uniform thickness (avoid thin sections) | Prevents warping and ensures even cooling |
Contre-dépouilles & Features | Use mechanical interlocks or undercuts | It improves adhesion and prevents delamination |
Bonding Surface | Increase surface roughness or use texture | Enhances adhesion between layers |
Conception de moules | Venting and proper flow paths | Reduces air traps and defects |
Gate Placement | Position away from critical bond areas | Ensures proper material flow and bonding |
Shrinkage & Tolérance | Design for material shrinkage differences | Prevents misalignment and defects |
Cooling Strategy | Uniform cooling channels in mold | It prevents warping and enhances the quality |
Overmolded Part Size | Avoid excessive thickness in over-molded layer | Prevents stress concentration & cracking |
Volume de production | Choose the right molding process (manual vs. automated) | Balances cost and efficiency |
We work systematically and quality-driven to get flawless overmolding results.
We’ll talk about your project requirements, material selection, and design considerations, to optimize the function.
We prototype rapidly to test the material compatibility, force, and performance before building at full scale.
Tolérances étroites, defect-free production without defects, and our advanced molding machines.
Strict inspection of material adhesion, durabilité, and dimensional accuracy of every over-molded part.
En outre, we provide on-time delivery and scalable production for small-batch or large-volume orders.
Choosing appropriate materials for overmolding is essential in producing durable, fonctionnel, and tightly bonded layers. Typically an overmold merges a more rigid base material (substrate) with a softer overmold material for improved grip, comfort, or protection.
