Detail Information
Custom LSR Overmolded Sensor Sealing Components
SiliconePlus manufactures custom LSR overmolded sensor sealing components for automotive sensors, electronic sensors, wearable sensing modules and industrial detection devices.
For sensor products, sealing failure may cause moisture ingress, unstable signal output, corrosion, dust contamination or early component failure. LSR overmolding helps integrate the silicone sealing area directly onto the plastic housing, metal insert, FPC or sensor module structure.
This is not a standard silicone gasket. It is a custom waterproof silicone overmolding solution based on your drawing, sample, substrate material, assembly method and testing requirement.
Designed for Sensor Sealing and Protection
Sensor sealing parts usually need to protect sensitive areas such as cable exits, connector interfaces, FPC edges, plastic housings, metal inserts and detection windows.
SiliconePlus can customize the silicone coverage area, sealing lip, bonding edge, compression structure and overmolded thickness according to your final assembly. This helps improve waterproof sealing, dustproof protection, insulation and vibration resistance.
For automotive silicone overmolding projects, the sealing structure should also consider temperature change, vibration, oil exposure, aging resistance and long-term assembly stability.
Key Engineering Points
Sealing Path Design
The silicone sealing path can be customized around connector areas, sensor housings, cable exits or FPC edges.
Insert Positioning
Plastic, metal, FPC or sensor modules need stable positioning during LSR injection molding to reduce offset and flash risk.
Bonding Evaluation
Substrate material, surface condition, bonding area and silicone grade should be reviewed before mold development.
Waterproof Target
IP67 or IP68 sealing performance should be evaluated together with the complete product structure and final assembly test.

Custom Structure Options
Different sensor projects require different silicone overmolding structures. Some products need silicone over plastic housing, some need silicone over metal inserts, and some need FPC silicone overmolding around flexible circuit areas.
Common structure options include sealing lips, cable exit protection, connector interface sealing, soft-touch cover areas, strain relief ribs, bonding edges, dustproof barriers and overmolded insulation zones.
Silicone hardness, wall thickness, compression ratio, parting line position, gate location and venting design should be confirmed before tooling starts.
Application Areas
Automotive Sensors
Used for EV sensors, connector sealing areas, wire harness sensor modules and automotive electronic protection parts.
Wearable Sensors
Suitable for skin-contact sensor modules, FPC sealing areas, sweat-resistant structures and compact waterproof parts.
Industrial Devices
Used for detection modules, outdoor sensor housings, cable transition zones and dustproof electronic components.
Medical Electronics
Suitable for medical electronic modules, diagnostic device parts and precision sealing components requiring stable production control.
