Sunkai is a professional manufacturer and supplier of multi-layer rubber airbags. As a direct-source factory, we specialize in customizing rubber airbags with varying layer counts, dimensions, and pressure ratings to suit our clients' specific operational environments. Our products comprehensively cover a wide range of critical applications, including ship launching and docking, heavy object lifting, stranded vessel rescue, and cargo transfer in shallow waters. We invite you to contact us with your inquiries and requirements; our expert team is ready to provide you with the most professional and tailored solutions.
Sunkai Multi-layer Rubber Airbags are manufactured using a composite process that combines high-quality rubber with high-strength cord fabric. The multi-layer structure is tightly bonded without any voids, offering exceptional resistance to abrasion and tearing. With stable pressure retention capabilities, these airbags are capable of withstanding complex marine environments and various harsh operational scenarios. All products strictly adhere to international industry standards and undergo rigorous multi-stage testing for airtightness and pressure resistance, thereby ensuring safe and reliable operations.
Our factory meticulously selects high-toughness, premium-grade rubber and high-strength cord fabric as our core raw materials. These materials undergo rigorous professional inspection to eliminate impurities, thereby ensuring full compliance with quality standards. Subsequently, they proceed to a multi-layer compounding stage, where the rubber and cord fabric are precisely bonded according to custom specifications. Through a high-temperature, high-pressure curing process, the various layers are fused tightly together—free of voids or delamination—fundamentally enhancing the airbag's resistance to abrasion and tearing.
