# Industrial Mining Light LSR Sealing Overmolding Part
---
Industrial mining lighting systems operate in some of the harshest environmental conditions in the industrial sector, requiring reliable sealing solutions that resist moisture, dust, vibration, and temperature fluctuations. Our Industrial Mining Light LSR Sealing Overmolding Part is a custom-molded liquid silicone rubber (LSR) component designed specifically to create permanent, leak-proof seals between housing components of high-power industrial mining lights.
Manufactured by 橡楚（湖北）橡胶有限公司 at our 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 overmolded sealing parts combine the excellent elasticity and chemical resistance of LSR with precision bonding to metal or plastic light housing frames. Unlike traditional cut gaskets or adhesive-bonded seals, our overmolding process forms a monolithic integrated seal that eliminates gaps, reduces assembly steps, and delivers longer service life in underground mining, open-pit mining, and heavy industrial processing applications.
Core selling points of our product include: custom dimensional alignment matched to your mining light housing design, long-term compression set resistance for consistent sealing performance, full compatibility with high-power LED heat output, and resistance to common mining industry contaminants including oil, dust, and humidity.

Compared to alternative sealing solutions (such as cut rubber gaskets, EPDM seals, or adhesive-bonded silicone seals), our LSR overmolding parts deliver four key advantages for industrial mining light applications:
Our overmolding process bonds LSR directly to the light housing substrate during curing, creating an integrated seal with no gaps between the seal and housing. This eliminates the risk of seal displacement, loosening, or leakage caused by vibration during mining equipment movement, a common failure point for loose gaskets.
LSR outperforms EPDM and other general rubber materials in harsh mining conditions: it resists UV degradation for open-pit mining applications, maintains elasticity at sub-zero underground temperatures, and does not crack or harden when exposed to long-term heat from high-power LED chips. The low compression set ensures the seal maintains consistent pressure even after years of use, avoiding performance degradation that requires premature replacement.
LSR injection overmolding can produce complex seal geometries, including irregular edges, stepped profiles, and integrated locating tabs that match the exact dimensions of your mining light housing. We can adjust part hardness and thickness to meet your specific assembly and sealing requirements, with tolerances as tight as ±0.05 mm for small-to-medium sized sealing parts.
Integrated overmolded seals eliminate the need for on-site assembly of separate gaskets, reducing labor time and the risk of incorrect gasket placement during light manufacturing. The longer service life of LSR also reduces maintenance and replacement costs for end users in the mining industry, making our overmolding parts a cost-effective long-term solution.

Our Industrial Mining Light LSR Sealing Overmolding Parts are designed for a wide range of high-power lighting applications in the mining and heavy industrial sectors:
Application notes: These sealing parts are designed to provide environmental ingress protection for lighting assemblies. They are compatible with most common housing materials used in industrial lighting manufacturing, and can be customized to fit any standard or custom mining light housing size.

To select the correct LSR sealing overmolding part for your industrial mining light, please consider the following factors:
We produce custom overmolding parts matched exactly to your housing design, with no minimum order quantity for custom development. Common standard sizes fit 100mm to 500mm diameter round mining lights, and rectangular housing designs up to 800mm in length. All dimensions can be adjusted according to your CAD drawings to ensure perfect alignment during assembly.
