Business Areas

• Silicone raw material extrusion and mold molding processing: We mix and mold silicone raw materials to produce customized silicone products according to the drawings and specifications required by clients. Through precise injection and extrusion processes, we stably mass-produce molded parts that maintain high heat resistance and excellent elasticity.
• Manufacturing of silicone packing and gaskets for industry and construction: We manufacture silicone gaskets and hoses used in areas requiring airtightness and waterproofing, such as building exteriors, facility piping, and electronic devices. They have excellent durability and weather resistance, providing stable sealing performance without deformation in various environments.
• Development of high-functional silicone materials: We develop and supply high-value-added functional product lines such as heat-conductive sheets, self-fusing silicone tape, and high-elasticity silicone sponges. We are actively responding to fields requiring high functionality, such as heat management for electrical and electronic components and special insulation work.

Products

• Silicone gaskets, hoses, and air tubes: These are essential parts that help maintain airtightness and fluid transfer for construction and industrial equipment. They feature excellent resistance to high temperatures and chemicals, functioning stably for long periods.
• High-elasticity silicone sponge: This is a silicone material product that exhibits excellent resilience and cushioning effects with a uniform foam structure. It is widely applied to various industrial machines and parts that require vibration damping, sound absorption, and thermal insulation.
• Heat-conductive sheets and self-fusing tape: These are special silicone product lines that efficiently dissipate heat from electronic devices and ensure electrical insulation. Self-fusing tape fuses to itself without a separate adhesive, providing reliable insulation and waterproof performance.

Special Notes

• Over 30 years of accumulated silicone molding technology know-how: Through a long history of operation, we have accumulated rich technical data ranging from raw material mixing to extrusion, injection, and vulcanization processes. Based on this accumulated know-how, we respond quickly to the demanding physical property requirements of our clients.
• Production infrastructure based on the 1st and 2nd factories: We operate the 1st factory (headquarters) and the 2nd factory in Haseong-myeon, Gimpo-si, Gyeonggi-do, and have established systematic manufacturing facilities. Through multiple production facilities, we flexibly respond to large-scale orders and high-mix, low-volume production.
• Product lineup covering various industrial sectors: We possess a wide portfolio ranging from general packing and gaskets to construction materials and heat-dissipating sheets for electronic components. We have built trust in the industry through uniform quality control and continuous technological innovation.

💡 A Word from JOBPLOY
Dongsung Silicone Co., Ltd. is a company that manufactures parts by mixing silicone raw materials and performing extrusion and mold molding. Since there are many processes involving molding presses and extrusion machines that use heat, it is essential to wear safety protective gear such as heat-resistant gloves and follow machine safety rules. The work includes tasks that require careful attention, such as product dimension inspection and burr removal. As the workplace is located in Haseong-myeon, Gimpo-si, it is recommended to carefully check commuting routes and accommodation-related matters before joining the company.
