# Custom LSR Waterproof Gasket For Industrial Lamps
*(工矿灯密封件防水件)*
---
Custom LSR (Liquid Silicone Rubber) Waterproof Gaskets for Industrial Lamps are precision-engineered sealing components designed to meet the rigorous moisture and dust ingress protection requirements of high-output industrial mining and general industrial lighting fixtures. Manufactured by 橡楚（湖北）橡胶有限公司 at our dedicated production facility in 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, these gaskets leverage the inherent performance benefits of LSR to deliver long-term reliable sealing in harsh operating environments common to mining sites, manufacturing plants, and heavy industrial facilities.
Unlike generic cut rubber gaskets, our custom-molded LSR waterproof gaskets are produced to match the exact dimensional and tolerance requirements of your specific industrial lamp housing design. We cater to custom geometries, including irregular housing flanges, integrated cutouts for wiring, and varying compression profiles, ensuring a perfect fit that eliminates gaps and maintains consistent sealing performance over the lifespan of your lighting fixture. These gaskets provide IP65 to IP68 level ingress protection when properly installed, preventing water penetration, dust accumulation, and corrosion of internal electrical components that commonly cause premature lamp failure in challenging industrial conditions.

Our industrial lamp waterproof gaskets are manufactured from 100% high-purity addition-cured liquid silicone rubber, formulated specifically for long-term outdoor and heavy industrial use. Key material properties include:
We offer formulations tailored to different compression and temperature requirements, with standard performance parameters as follows:
All custom gaskets are produced via precision liquid injection molding (LIM) to ensure consistent part-to-part uniformity:
---
LSR inherently retains its elasticity and sealing force far longer than organic rubber alternatives such as EPDM or nitrile. In the temperature-fluctuating, high-humidity conditions common to mining and industrial sites, LSR resists compression set, which prevents gasket relaxation that causes water leakage over time. This consistent sealing performance reduces maintenance frequency and extends the service life of your industrial lamps.
Our LIM manufacturing process enables us to produce gaskets for any custom industrial lamp geometry, from small 100W LED mining lamps to large 1000W high-bay industrial fixtures. We can integrate custom features such as locating tabs, mounting holes, stepped profiles, and adhesive backing for easy assembly directly into the molded part, eliminating secondary processing steps and reducing your production assembly time.
Industrial mining lamps operate across a wide range of temperatures, from freezing winter conditions in open-pit mines to high heat generated by high-output LED chips. Our LSR gaskets maintain their elasticity and sealing performance from -40°C to +200°C, resisting thermal degradation that causes cracking or brittleness in lower-grade materials. LSR is also inherently UV and ozone resistant, making it suitable for both underground mining and exposed above-ground industrial lighting applications.
Our platinum-cured LSR formulation is non-corrosive to copper wiring and aluminum lamp housings, avoiding the galvanic corrosion and electrical degradation issues that can occur with lower-quality rubber compounds. Low-halogen and low-toxicity formulations are available to meet international electrical safety requirements, with no harmful volatile organic compound (VOC) emissions during operation.

Our custom LSR waterproof gaskets are designed specifically for sealing industrial mining and general industrial lighting fixtures, with common use cases including:
---
Choose the appropriate Shore A hardness based on your lamp housing design and compression requirements:
All our gaskets are custom manufactured to match your exact product drawings or sample dimensions. We accept 2D CAD drawings, 3D STEP/IGS models, or physical samples for reverse engineering to produce an exact match to your sealing requirements. There is no minimum order quantity for custom development, and we support small-batch prototype production for product testing prior to full-scale manufacturing.
Select the right material formulation based on your application requirements:

At 橡楚（湖北）橡胶有限公司, we maintain a rigorous quality management system certified to ISO 9001, with every production batch tested to ensure compliance with specified performance and dimensional requirements. Our quality control process includes incoming raw material inspection, in-process dimensional checks for every molding run, and final performance testing for compression set, hardness, and visual quality before shipment.
We work closely with industrial lamp manufacturers to develop gaskets that meet your specific performance requirements, and provide full material test reports with every batch. For custom development projects, we offer prototype samples for your in-house ingress protection and environmental testing before full production.
