Precision LSR Injection Molding for Custom Silicone Components
ESKY supports liquid silicone rubber projects from mold development and material selection through precision molding, inspection and repeat production.

ESKY supports liquid silicone rubber projects from mold development and material selection through precision molding, inspection and repeat production.
Product development and dedicated tooling around your application.
Quality control, assembly, packaging and shipment coordination.
WHY LSR
Liquid silicone rubber suits parts where detail, consistency and material performance matter together.
Small features molded cleanly and repeatably.
Complex shapes handled efficiently by injection molding.
Consistent dimensions across high-volume batches.
Sealing lips and gasket features molded in place.
Skin-contact and tactile surfaces.
LSR bonded over sensitive inserts and substrates.

CAPABILITY
LSR projects run on dedicated injection molding cells with in-house mold development and precision inspection support.
MATERIAL & DESIGN
These design topics are reviewed together at DFM, because each one affects the others.
Matched to function and feel.
Positioned around appearance and flash control.
Air trap management for complete filling.
Filled without short shots.
Gate and runner design for the geometry.
Shut-off and clamping strategy.
Compensated in the tool design.
Positioning and protection of inserts.
PROCESS
A structured path from review to stable LSR production.
Manufacturing route and critical features reviewed.
LSR grade and hardness proposed at DFM.
Tooling engineered around the geometry.
T1 samples produced and reviewed.
Dimensional and functional verification.
Pilot batch before full volume.
Final inspection before shipment.
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.
Balancing geometry, hardness and molding consistency for better tactile performance.
