While foam and fabric products form our core, our Rotomolding Technology represents the future of indestructible fitness gear. Rotational molding (rotomolding) is a process that creates hollow, one-piece plastic parts with consistent wall thickness and high impact resistance.
At Nantong Hengan, we leverage this technology to produce specialized gym components that are virtually indestructible. From custom-molded kettlebell shells to specialized equipment bases and outdoor fitness parts, our rotomolded products are UV-stable, weather-resistant, and seamless. This lack of seams means there are no weak points to crack or leak under pressure. For our OEM and ODM partners, this opens a world of possibilities. We can help you design and manufacture unique, patented fitness tools that offer superior longevity compared to traditional injection-molded alternatives. If your project requires high-durability plastic components, our in-house design and rotomolding team is ready to bring your vision to life.
