High-demand commercial and domestic trampoline architectures custom manufactured for Amazon top sellers, retail distributors, and commercial indoor fitness parks.
Zhejiang Lingsha Technology Co., Ltd. (Funjump) sets the global benchmark in engineered trampoline manufacturing, combining large-scale production capacity with rigorous metallurgical and textile engineering.
At Zhejiang Lingsha Technology Co., Ltd. (Funjump), we are committed to producing safe, stable, and scientifically designed trampolines tailored to international market requirements. Our comprehensive OEM/ODM manufacturing capability spans indoor and outdoor recreational systems, adult fitness rebounders, and toddler sensory play units.
Operating from a state-of-the-art facility spanning 68,000 square meters, our workforce of over 100 skilled engineers and specialized assembly technicians utilizes fully automated production lines. Our daily factory throughput exceeds 1,500 sets of completed trampolines, empowering global retail brands and cross-border e-commerce leaders (including top-ranked Amazon sellers) to achieve seamless market penetration and resilient supply chain performance.
To guarantee absolute safety compliance and zero-defect delivery, our factory houses a specialized, fully equipped trampoline safety testing laboratory. We maintain rigorous compliance certifications including ISO9001, BSCI, TÜV/GS, EN71-14, ASTM F381-16, and AS4989.
Exploring how specialized OEM inside trampoline manufacturing adapts to distinct commercial, residential, and clinical applications worldwide.
In compact metropolitan environments across Europe and North America, spatial footprint and noise vibration are critical constraints. Funjump's 55" indoor toddler trampolines utilize silent, high-tension elastic bungee cords and sound-dampening rubber feet instead of traditional metallic springs, reducing decibel transmission by up to 65% while providing a safe, low-impact bounce inside residential apartments.
Boutique fitness centers demand extreme structural durability. Our 40"-51" OEM fitness rebounders feature heavy-gauge Q235 steel tubing, T-bar height-adjustable stabilization handles, and commercial-grade 260g Polypropylene jumping mats. Engineered to sustain continuous daily dynamic loads exceeding 150 kg without frame distortion or mat fatigue.
Specialized pediatric therapy facilities utilize our quick-assembly inside trampolines to assist children with motor skill development, proprioceptive input processing, and balance control. Soft-enclosure safety netting combined with seamless frame padding guarantees zero contact with rigid structural metalwork during high-frequency therapeutic movements.
For large indoor commercial amusement parks, Funjump manufactures custom rectangular and circular trampoline systems engineered with curved safety poles, basketball hoops, and integrated climbing attachments. All materials comply with stringent international commercial playground safety standards.
Solving real-world consumer friction points through precise engineering and user-friendly structural design.
Historically, traditional trampolines presented significant consumer frustration regarding complex assembly, difficult spring tensioning, and labor-intensive seasonal disassembly. Balancing structural rigidity with ease of installation required radical engineering breakthroughs.
Through the dedicated efforts of the Zhejiang Lingsha (Funjump) R&D team, we successfully engineered proprietary foldable fitness rebounders and tool-free quick-disassembly mini trampolines. By utilizing precision-machined interlocking steel connectors and pre-tensioned bungee modules, end users can set up or store their trampoline within minutes without compromising structural frame stability.
This engineering milestone has unlocked tremendous commercial success for our international trade partners, directly propelling multiple partner brands to the #1 Best-Seller position on Amazon within the fitness and recreational toy categories.
Leveraging Zhejiang's world-class hardware supply cluster, deep raw material integration, and direct port logistics.
Situated in Zhejiang Province—China's primary hardware and steel processing hub—Funjump maintains direct long-term procurement contracts with top steel mills. We secure high-grade hot-dip galvanized steel tubing (with double-sided zinc coating >= 120g/m²) at stable, competitive prices, shielding our OEM client partners from global raw material price volatility.
Our facility enjoys direct access to Ningbo-Zhoushan Port, the world's largest container port by cargo throughput. This geographic proximity minimizes overland drayage costs, guarantees reliable vessel booking allocations, and supports standard FOB Ningbo trade execution with rapid turnaround times (10-35 days during off-peak, 35-55 days peak season).
From raw tube bending and automated robotic welding to high-density precision textile stitching and custom branded packaging, 100% of core production steps are executed in-house. This vertical integration guarantees strict quality control, rapid sample turnaround, and unmatched flexibility for private-label customization.
Comprehensive visual breakdown of our specialized metalworking, sewing, packaging workshops, and finished product logistics facilities.
Our dedicated QC laboratory conducts rigorous mechanical dynamic load testing, salt spray anti-corrosion trials, and UV degradation accelerated tests to eliminate defects prior to shipping.
Pioneering smart-sensor integration, advanced polymer materials, and next-generation springless kinetic bounce architectures.
Funjump is currently field-testing embedded micro-accelerometer sensors woven into the perimeter of PP jumping mats. These Bluetooth-enabled sensors measure impact force, bounce frequency, trajectory symmetry, and real-time caloric expenditure, syncing directly with iOS/Android fitness applications.
In alignment with global net-zero sustainability mandates, our material science laboratory is developing 100% recyclable Thermoplastic Polyurethane (TPU) jump mats. These mats match the high tensile strength of traditional polypropylene while allowing complete post-consumer cradle-to-cradle recycling.
Advancing beyond traditional steel springs, Funjump is expanding its modular composite bungee system. Utilizing multi-strand natural latex cores encapsulated in friction-resistant nylon braiding, these cords deliver smooth, progressive deceleration—eliminating joint stress and operational noise.
Detailed technical alignment across North American, European, and Asia-Pacific toy safety and recreational equipment directives.
