Based in Dongguan, Guangdong—China’s premier hub for high-performance silicone component manufacturing—HS specializes in high-temperature custom dimension silicone seals, engineered as insulating, flame-retardant silicone gaskets for LED lighting, PC power supplies, and industrial machinery applications. Our EE-917-C4 silicone rubber gasket seals (also referred to as silicone rubber seals) are precision-crafted via moulding processing to meet the strict thermal and safety standards of electronics manufacturers, combining high-temperature resistance, electrical insulation, and full customization to deliver reliable machinery accessory solutions worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke flame-retardant gaskets for PC power supplies, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your LED lighting and electronics sealing needs.
Core Features of Our Silicone Seals & Gaskets Our silicone seals and silicone rubber gasket seals stand out for their high-temperature resistance, flame retardancy, and insulating performance—key traits that make them ideal for LED lighting, PC power supplies, and industrial machinery accessories.First, the material quality of our silicone seals is unmatched. We utilize premium silicone rubber (supplemented with EPDM, NBR, and NR options) that delivers exceptional high-temperature resistance (withstanding up to 260°C), flame retardancy (UL94 V-0 rated), and electrical insulation (dielectric strength ≥20 kV/mm), ensuring silicone rubber gasket seals protect sensitive electronics from heat, fire risks, and electrical leakage. This formulation maintains flexibility and structural integrity across extreme temperature ranges (-50°C to 260°C), critical for LED lighting and PC power applications.Second, custom dimension precision defines our silicone seals. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber seals fit seamlessly into LED light housing enclosures, PC power supply casings, and industrial machinery control panels—eliminating gaps that compromise insulation or thermal management. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber gasket seals with electronics brand identity without compromising performance.Third, durability is embedded in every silicone seal we produce. The robust silicone composition resists UV degradation, thermal aging, and chemical exposure, extending the service life of LED lighting and PC power components while reducing maintenance costs for electronics and industrial manufacturers alike.
Competitive Advantages of Our Silicone Seals & Gaskets Choosing our silicone seals and silicone rubber gasket seals means partnering with a manufacturer with 20+ years of silicone processing expertise, prioritizing safety, customization, and customer-centric service for electronics and industrial applications. High-Temperature & Flame-Retardant Compliance Every silicone seal undergoes 100% quality inspection before shipment, including high-temperature resistance testing, flame retardancy validation (UL94 V-0), insulation performance checks, and dimensional verification—ensuring zero defects and adherence to global electronics safety standards. Our strict quality control processes guarantee silicone rubber gasket seals meet the thermal and safety benchmarks required for LED lighting, PC power supplies, and industrial machinery. Custom Dimension Flexibility & Scalable Production We offer a MOQ of 500 pieces for silicone seals, making our solutions accessible to small and medium-sized electronics manufacturers, while our 10,000-square-meter production facility and 2000+ existing molds enable scalable production to meet bulk orders for major LED and PC power brands. Custom sizes, shapes, and material blends (silicone/EPDM/NBR/NR) for silicone rubber seals are available to fit any LED lighting, PC power, or industrial machinery component. Cost-Effective Factory-Direct Pricing As a direct manufacturer, we eliminate middleman markups, offering competitive pricing on high-temperature silicone seals without compromising flame retardancy or insulating performance. Our one-stop procurement service streamlines design, prototyping, and production, reducing lead times and supply chain costs for your LED lighting, PC power, and industrial machinery component orders. Technical Expertise & 24/7 Support Our team of silicone engineering specialists provides 7×24 online support for silicone seal inquiries, offering guidance on material selection and design optimization for LED lighting thermal management, PC power insulation, and industrial machinery safety. We leverage deep electronics industry knowledge to solve complex sealing challenges, ensuring silicone rubber gasket seals deliver optimal high-temperature and flame-retardant performance.
Applications of Our Silicone Seals & Gaskets Our versatile silicone seals and silicone rubber gasket seals serve critical sealing roles in electronics and industrial settings, thanks to their high-temperature resistance, flame retardancy, and insulating design:
LED Lighting Enclosures: Silicone seals act as insulating gaskets for LED panel lights and high-bay lighting housings—their high-temperature resistance dissipates heat from LED chips, while flame retardancy reduces fire risks in commercial lighting installations. PC Power Supplies: Custom-dimension silicone rubber gasket seals insulate power supply casings and component interfaces—their electrical insulation prevents short circuits, and flame retardancy complies with electronics safety standards for consumer and industrial PCs. Industrial Machinery Control Panels: Silicone seals seal electrical enclosures in industrial machinery—their high-temperature resistance withstands factory heat, and insulating performance protects operators from electrical hazards. Automotive LED Lighting: Flame-retardant silicone rubber gasket seals fit automotive headlight and taillight assemblies—their high-temperature resistance withstands engine bay heat, and custom dimensions ensure a perfect fit for vehicle lighting designs. Server Power Units: Silicone seals insulate server power supply units (PSUs)—their flame retardancy meets data center safety standards, and high-temperature resistance optimizes thermal management in high-density server racks.
At our Dongguan manufacturing facility, we leverage a team of over 100 skilled professionals and state-of-the-art moulding processing equipment to produce silicone seals that exceed industry standards. Our commitment to quality is backed by ISO 9001 and ISO 14001 certifications, validating the reliability and sustainability of our silicone rubber gasket seals for international electronics and industrial markets. We back all silicone seals with a 3-year warranty: if unused silicone rubber gasket seals develop quality issues within this period, we offer free returns and replacements. Whether you need high-temperature insulating gaskets for LED lighting or flame-retardant seals for PC power supplies, we deliver silicone rubber gasket seals that combine safety, performance, and value—engineered for electronics, built to protect.
