PCB Overmolding Services
EI Sales connects OEMs to advanced PCB overmolding solutions for electronics that face harsh conditions. Overmolding adds a protective layer over the circuit board or subassembly, forming a sealed structure that resists contamination, vibration, and mechanical stress.
This method reinforces assemblies without complex secondary housings and is common in portable devices, industrial controls, and field-deployed electronics where durability is critical.
PCB Overmolding Capabilities
Our PCB overmolding programs are built around board geometry, material compatibility, and environmental exposure. Each project is reviewed for thermal impact, component clearance, and long-term performance under mechanical load.
Low-Pressure and High-Pressure Overmolding
Low-pressure systems safeguard sensitive components, while high-pressure molding supports structural reinforcement and higher production volumes.
Full and Partial PCB Encapsulation
Boards can be fully encapsulated for maximum sealing or partially overmolded to protect connectors, sensors, or exposed circuitry, depending on performance needs.
Customized Molded Housings for PCBs
Molded housings are designed around the board layout to reduce separate enclosures and simplify final assembly.
Protection Against Moisture, Dust, and Chemicals
Overmolding creates a barrier against water ingress, airborne contaminants, and industrial chemicals, extending product life in demanding settings.
Mechanical Reinforcement for Harsh Environments
The molded material absorbs shock and vibration while strengthening solder joints and component leads in mobile or high-impact applications.
Integration of Mounting Features and Cable Strain Relief
Mounting tabs, alignment guides, and strain relief features can be built into the molded structure to reduce hardware count and streamline assembly.
Overmolding for Rigid, Rigid-Flex, and Flex PCBs
Rigid, rigid-flex, and flex circuits are supported, including complex geometries and mixed-material constructions.
Compatible with Thermoplastics and Polyurethanes
Engineered thermoplastics and polyurethanes are chosen based on temperature resistance, flexibility, and chemical exposure requirements.
Low-Pressure and High-Pressure Overmolding
Low-pressure systems safeguard sensitive components, while high-pressure molding supports structural reinforcement and higher production volumes.

Get Rugged PCB Protection Without Redesign
Overmolding strengthens assemblies without major layout changes or complex housing redesign. Existing board designs can often be adapted for molding through targeted tooling updates.
This strategy shortens development timelines while adding environmental sealing and structural reinforcement, reducing reliance on separate enclosures or potting compounds.
Built for Harsh, High-Demand Applications
Overmolded assemblies operate in environments that see vibration, moisture, temperature variation, and mechanical stress. Tooling is developed with close attention to material flow, venting, and shrink characteristics to maintain dimensional stability and component clearance.
Production planning includes defined inspection checkpoints to maintain consistency across manufacturing runs and verify critical dimensions.
