PRECISION INSERT MOLDING & OVERMOLDING
U.S.-Based Insert Molding Specialists
Serving the Medical Industry from the Heart of Georgia
Precision When It Matters
Insert Molding Solutions has the capabilities to meet the most demanding and precise needs of the medical industry. From insert molding and overmolding to injection molding and 3D additive manufacturing.
Prototyping & Low-Volume Runs
From first-article samples to short production runs, we take on the difficult, lower-volume work that high-volume molders pass on.
Why Insert Molding Solutions
Demanding Work.
Done In-House.
From our Cumming, Georgia facility, Insert Molding Solutions is equipped to fulfill the most demanding and precise molding needs. We bring insert molding, overmolding, injection molding, and 3D additive manufacturing together in one place, so your project moves from concept to finished part without the delays and quality gaps that come from multiple suppliers.
Insert molding, overmolding, and 3D additive in one facility
Difficult, high-tolerance components other shops turn away
Prototyping through production with a single partner
Tighter tolerances and improved part reliability
Insert Molding
Plastic molded around metal inserts and pre-placed components for strong, integrated parts.
Overmolding
A second material molded over a substrate for grips, seals, strain relief, and multi-material parts.
Injection Molding
Precision injection molding for components and full production, for tight tolerances and repeatability.
3D Additive Manufacturing
Rapid prototyping, tooling aids, and end-use production parts, all printed in-house and ready to scale.
What Is Insert Molding?
And Is It Right for Your Part?
Insert molding places a pre-formed component — often a metal pin, threaded insert, or electronic contact — into the mold, then injects plastic around it to create a single integrated part.
What's the difference between insert molding and overmolding?
Both place a component into the mold before injecting plastic, but they solve different problems. Insert molding forms plastic around a pre-placed part such as a metal pin, threaded insert, terminal, or electronic contact to create a single integrated component. Overmolding adds a second material over an existing molded substrate, often a softer material over a rigid one, for things like grips, seals, strain reliefs, and multi-material housings.
What are the benefits over assembling parts separately?
Molding components into one piece removes downstream assembly steps, which lowers labor and handling costs and reduces the chance of assembly errors. The result is also stronger and more reliable. The plastic locks the insert in place far more securely than press-fitting or fastening after the fact, and parts come out dimensionally consistent from one run to the next. For higher quantities, that consolidation can meaningfully reduce your total cost per finished unit.
What types of inserts can be molded?
A wide range of pre-formed components can be molded in place, including threaded metal inserts, pins and studs, terminals and electrical contacts, bushings, blades, and other metal or pre-molded plastic parts. The right approach depends on the insert’s material, size, and how it needs to seat in the finished part, which is something we’ll review with you before tooling.
What materials do you work with?
We work with a broad range of engineering and commodity resins selected to match your part’s strength, temperature, and regulatory requirements, along with the metal and pre-formed inserts your design calls for.
What production volumes do you handle?
We specialize in the work that doesn’t fit the high-volume offshore model, including prototyping, first articles, and low-to-mid-volume production runs, with the flexibility to scale as your needs grow.
