Explore our factory-direct wholesale fitness rebounders, mini trampolines, and outdoor safety trampoline series designed for global brands, commercial gyms, and distributors.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) operates at the nexus of biomechanical engineering and smart manufacturing, providing certified trampoline equipment for global brands.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) is committed to producing safe, highly stable, and high-performance trampolines. We specialize in custom manufacturing across diverse product categories, including indoor mini rebounders, commercial fitness trampolines, toddler activity enclosures, and heavy-duty outdoor recreational trampolines.
Our operation is underpinned by international quality assurance standards. We have successfully earned certifications including ISO9001, BSCI, GS (Geprüfte Sicherheit), EN71-14, ASTM F381/F2225, and AS4989. To maintain an unyielding commitment to safety, our factory houses a specialized trampoline physical & mechanical testing lab, staffed by certified inspectors who systematically eliminate potential defects prior to packaging.
Spanning a modern production footprint of 68,000 square meters and powered by a skilled workforce of over one hundred professionals, our facility integrates high-precision automated welding, CNC tube bending, and robotic sewing units. With a daily capacity exceeding 1,500 sets of trampolines, we deliver robust supply chain reliability to partners in North America, Europe, and Asia-Pacific.
Solving the fundamental B2B trade-off: Combining rapid toolless assembly with structural rigidity and commercial-grade durability.
At Zhejiang Lingsha Technology Co., Ltd. (Funjump), we actively integrate customer feedback into iterative hardware engineering. Traditional trampolines suffer from complex installation routines and difficult storage mechanics. Resolving this challenge required solving a complex design paradox: introducing movable joints and quick-release connectors without sacrificing frame stability during high-G acceleration.
Through dedicated structural analysis, our engineering team designed patented foldable fitness rebounders and quick-assembly mini trampolines that assemble and break down with virtually zero external tools. This innovation drastically reduces end-user return rates for e-commerce clients while optimizing shipping carton volumes by up to 35%.
We pride ourselves on long-term OEM/ODM partnerships. Our manufacturing standard enables international trade partners and top-tier e-commerce brand owners (including Amazon Category Leaders) to dominate their market segments through superior durability, whisper-quiet bungee systems, and pristine visual design.
Exploring the mechanical evolution, material science breakthroughs, and smart-sensor integration driving modern commercial rebound equipment.
Replacing traditional steel coil springs with high-elasticity synthetic latex bungee cords. Custom-formulated multi-strand latex cores wrapped in UV-resistant polypropylene offer a progressive deceleration curve, reducing peak force impact on knee and spine joints by 68%.
Utilizing high-tensile Q235 and Q345 cold-rolled galvanized steel tubing with dual-sided hot-dip anti-corrosion coating (1.5mm to 2.5mm wall thickness). Precision internal swaging prevents structural fatigue at high-frequency vibration points.
Incorporating embedded tri-axial accelerometers and BLE 5.0 telemetry modules into commercial fitness rebounders. Enables real-time tracking of jump velocity, vertical G-force, cadence, and caloric expenditure synced directly to fitness apps.
Heavy-duty 260g/m² Permatron® PP jumping mats reinforced with 8-row V-ring precision stitching using bonded nylon thread. Resists up to 5,000 hours of accelerated solar UV weathering without tensile degradation.
