Hongwo stands out as a pioneering NBR foam manufacturer in Asia
HONGWO builds core competitiveness via diversified foam processing technologies. We are equipped with intelligent automatic production equipment and supported by professional technical teams with rich foam industry experience, delivering full-process customized processing solutions aligned with clients’ product targets. Versatile processing enriches foam forms and functions while consistently guaranteeing stable performance and quality. Moving forward, we keep upgrading intelligent production lines and eco-friendly crafts, supplying competitive foam product solutions for global partners and maintaining leading position within the industry.
Precision Cutting Technology
Equipped with automatic CNC cutting equipment, we process NBR foam substrates into various sizes, thicknesses and contours according to customer drawings and specifications. High-precision cutting ensures dimensional consistency and flat surface with controllable tolerances, meeting demands for mass standardized production and special-shaped customization while guaranteeing assembly accuracy.
Flexible Hot Press Molding Technology
With mature hot press molding technology, various textures, embossed patterns and structural contours can be formed on NBR foam. Flexible molding processes expand design possibilities. We create differentiated shapes for water floats and protective cushions, endowing products with unique market competitiveness.
Reliable Adhesive Lamination Technology
Our advanced adhesive lamination firmly bonds NBR foam with fabrics, films and hard panels. The composite layer resists peeling and repeated bending. It expands foam functionality to enhance sealing, shock absorption and anti-slip performance for industrial gaskets, fitness accessories and protective liners.
Exquisite Sewing Technology
Our professional sewing team achieves precise stitching between foam and fabrics to realize complex 3D structures. Meticulous sewing improves structural durability and appearance quality, widely applied in life-saving buoyancy gear, sports protectors and functional water products, balancing durability and aesthetics.
Eco Water-based Dipping Coating Technology
Leading water-based dipping technology fully replaces oil-based coating. A dense protective layer is formed on foam surface to boost resistance against water, chlorine, UV radiation and tearing. Finished goods are non-toxic, odorless and phthalate-free, complying with global environmental standards, serving as our core differentiated technology for water buoyancy products.
One-step Mold Foam Forming Technology
Our self-developed one-step mold forming technology requires no extra coating, with integrated foam shaping. Products feature uniform texture, anti-peeling & anti-cracking property and ultra-low water absorption. Solid color mixing is available, ideal for high-end water articles and life-saving goods requiring zero solvent emission and long service life.
