# Liquid Silicone Glass Frame Overmolding Sleeve
Produced by 橡楚（湖北）橡胶有限公司
---
Liquid Silicone Glass Frame Overmolding Sleeve is a custom-molded protective component manufactured by 橡楚（湖北）橡胶有限公司 from high-purity food-contact compatible liquid silicone rubber (LSR), designed to overmold the exposed edges of glass panels and frames to deliver impact absorption, sealing, and user safety protection.
Our overmolding sleeves are produced via precision LSR injection molding, ensuring consistent dimensional tolerance and strong adhesion between the silicone sleeve and glass substrate (or integrated plastic/metal framing members) for long-term durable performance. Unlike extruded rubber gaskets or cut-to-size protective strips, our custom-molded LSR overmolding sleeves form a seamless, gap-free fit around entire glass frame perimeters, eliminating moisture ingress points and weak edges that can degrade over time. Ideal for a wide range of residential, commercial, and industrial glass applications, our product balances soft touch comfort, UV resistance, and thermal stability to outperform alternative protective materials in long-term use.
At 橡楚（湖北）橡胶有限公司, we manufacture custom Liquid Silicone Glass Frame Overmolding Sleeves tailored to exact client specifications, supporting small-batch prototype development and full-scale mass production to meet project requirements.

Our Liquid Silicone Glass Frame Overmolding Sleeves are produced from 100% pure addition-cure liquid silicone rubber, with no fillers or recycled rubber content added. Key material properties include:
Below are standard performance parameters for our Liquid Silicone Glass Frame Overmolding Sleeve. Custom adjustments can be made to meet specific application requirements:
Our standard production parameters are controlled to ensure consistent quality for every order:

Unlike assembled or spliced protective strips, our precision LSR injection molded sleeves form a continuous, gap-free perimeter around glass frames. This design eliminates gaps where moisture, dust, or debris can accumulate, preventing corrosion of metal framing and water damage to adjacent building or equipment components. The seamless structure also eliminates sharp edges at splice joints, improving overall user safety.
Liquid silicone rubber’s inherent chemical structure provides outstanding resistance to UV radiation, ozone, extreme temperature fluctuations, and moisture, outperforming organic rubber (EPDM, neoprene) alternatives. Our overmolding sleeves will not crack, harden, discolor, or deform after years of outdoor exposure, maintaining protective performance and appearance far longer than alternative materials, reducing long-term replacement and maintenance costs.
The elastic nature of LSR absorbs impact energy effectively, reducing the risk of chipping, cracking, or shattering of glass edges when bumped or jostled. For applications where users may come into contact with glass edges, the soft, non-abrasive silicone surface prevents cuts and scrapes, making it ideal for high-traffic and public use applications. Even in low-temperature environments, the sleeve maintains its flexibility, retaining impact absorption performance that rigid protective covers cannot match.
We produce fully custom Liquid Silicone Glass Frame Overmolding Sleeves tailored to exact glass frame dimensions, profile shapes, hardness, and color requirements. Whether you need a small square sleeve for a 100 mm instrument glass panel or a large continuous sleeve for a 3 m architectural glass door, our injection molding process can accommodate a wide range of sizes and profile designs to match your project specifications.
