ESKY manufactures custom silicone overmolded components using plastic, metal and engineered inserts for applications that require sealing, grip, cushioning, protection or integrated soft-touch surfaces.
Product development and dedicated tooling around your application.
Quality control, assembly, packaging and shipment coordination.
WHAT WE OVERMOLD
Explore substrate combinations, insert molding and functional applications. Material compatibility and tooling requirements are reviewed during DFM.
Rigid plastic substrates overmolded with sealing and soft-touch silicone features.
Metal inserts and housings bonded with silicone for structural and sealed assemblies.
Engineered inserts positioned and overmolded with repeatable shut-off control.
Connectors and electronic housings where contact areas must stay clean.
Grip and tactile surfaces molded directly onto functional parts.
Sealing rings and gasket features integrated into the overmolded part.
ENGINEERING CONSIDERATIONS
Successful overmolding depends on more than material choice. Substrate compatibility, insert positioning, local shut-offs, gate location, silicone flow, bonding method and molding pressure all affect part quality.
PROCESS
Early DFM review addresses material, bonding and tooling risks. Trial molding and validation confirm part performance before mass production.
Review your concept, drawing or CAD file for feasibility and manufacturing requirements.
Select compatible materials and evaluate bonding or mechanical retention methods for the application.
Shut-offs, gates and insert positioning engineered into the mold.
T1 samples reviewed against sealing and appearance requirements.
Validate dimensions, bonding and functional requirements against the criteria agreed for the project.
Stable repeat production with final inspection.
CASE STUDIES
Improving mold shut-offs, insert positioning and process control to keep silicone off electrical contact areas.
Managing support, positioning, flow and molding pressure around flexible electronic circuits.
Managing magnet positioning and molding conditions to protect magnetic performance during overmolding.
