# LED Module LSR Sealing Ring Overmolding Part
---
LED module sealing components are critical for protecting outdoor and industrial lighting systems from moisture, dust, and temperature fluctuations. Xiangchu (Hubei) Rubber Co., Ltd. manufactures LED Module LSR Sealing Ring Overmolding Parts using high-purity food-contact and industrial-grade liquid silicone rubber (LSR) to deliver reliable long-term sealing performance for LED lighting assemblies.
Unlike pre-formed rubber gaskets that require manual alignment during assembly, our overmolded sealing rings are directly bonded to the LED module frame or housing during manufacturing, eliminating gaps caused by misalignment and reducing assembly labor costs for lighting manufacturers. Our products are formulated to retain elasticity and sealing performance across extreme temperature ranges, resisting UV degradation and outdoor weathering that causes conventional rubber seals to crack, harden, or leak over time. As a specialized LSR product manufacturer based at No. 54, Neihe Alley, Fankou Sub-district, Echeng District Economic Development Zone, Ezhou City, Hubei Province, China, we produce custom overmolding parts tailored to the exact dimensional and performance requirements of standard and custom LED module designs.
Our LED Module LSR Sealing Ring Overmolding Parts are manufactured from 100% pure addition-cure liquid silicone rubber, with no recycled rubber or toxic filler additives. Key material properties include:
All standard overmolding parts meet the following performance benchmarks, with custom formulations available for specialized use cases:
Our overmolding process follows controlled parameters to ensure consistent bonding and dimensional accuracy:
As an overmolded component, our sealing rings are cured directly onto the LED module housing or frame, creating a permanent, gap-free bond that eliminates the risk of seal displacement during assembly or vibration. This integrated design achieves higher ingress protection ratings than loose-fit gaskets, even for irregularly shaped LED modules.
Unlike thermoplastic elastomers (TPE) or conventional organic rubber seals, LSR retains its elasticity and sealing performance after years of exposure to UV radiation, rain, and extreme temperature swings. Our formulations resist ozone degradation and yellowing, preventing seal failure that can cause short circuits or LED lumen degradation from water intrusion.
All our raw LSR materials are RoHS and REACH compliant, with low volatile organic compound emissions that do not outgas toxic fumes or cause fogging on LED lens surfaces. This is particularly critical for enclosed LED lighting systems, where outgassing can reduce light transmittance and shorten product lifespan.
Our precision liquid silicone injection molding process supports high-volume production of overmolding parts with consistent dimensional accuracy, reducing post-production sorting and rework costs. We can match overmolding production volume to your LED module manufacturing schedule, supporting just-in-time delivery for large-scale lighting projects.
We engineer custom overmolding parts to match the exact geometry of any LED module design, from small 10mm square modules for smart lighting to large 1m linear modules for outdoor billboard lighting. We can adjust hardness, bonding adhesion, and sealing profile to meet your specific assembly and performance requirements.
Our LED Module LSR Sealing Ring Overmolding Parts are designed for a wide range of indoor and outdoor LED lighting applications, including:
Choose the right LSR hardness based on your assembly method and sealing requirements:
We produce custom-sized overmolding parts to match your exact LED module dimensions, with common size ranges including:
Please provide your 2D CAD drawings or 3D model files for accurate quoting and sample production.
We offer two standard material grades to match different application requirements:
At Xiangchu (Hubei) Rubber Co., Ltd., we follow strict quality control processes aligned with our ISO 9001 certification to ensure every batch of LED Module LSR Sealing Ring Overmolding Parts meets published performance specifications. Our quality control process includes:
