Explore our premium-grade export models featuring high-tensile galvanization, UV50+ mats, and 360-degree safety nets.
Pioneering Safety Engineering, High-Throughput Automation, and Global OEM/ODM Solutions.
Zhejiang Lingsha Technology Co., Ltd. (operating globally under the flagship brand Funjump) stands as a premier authority in the global trampoline manufacturing landscape. With a modern production footprint spanning over 68,000 square meters and an agile workforce exceeding 100 skilled engineers and fabrication specialists, our infrastructure achieves a daily output capacity exceeding 1,500 complete trampoline sets.
Our operational framework is backed by international quality management systems, holding certifications such as ISO9001, BSCI, TÜV/GS, EN71-14, ASTM F381/F2225, and AS4989. By integrating an in-house specialized trampoline safety testing laboratory equipped with dynamic load simulators, salt-spray corrosion chambers, and UV endurance testers, we eliminate product deficiencies at the metallurgy and polymer level before shipment.
How China's Leading Manufacturer Overcomes Corrosion, Metal Fatigue, and High-Impact Deformations
Unlike standard external spray coatings, Funjump utilizes dual-sided internal and external hot-dip galvanization across all T-sections and leg tubes. Yield strength exceeds 240 MPa with a zinc coating thickness ≥ 120g/m², securing zero structural oxidation during prolonged 500-hour salt spray endurance tests.
Engineered using heat-treated high-carbon steel wire (70# spring steel), our waist-drum conical springs undergo 100,000-cycle dynamic bounce stress simulations. This geometry maximizes rebound energy efficiency while preventing permanent deformation under peak loads of up to 150 kg - 200 kg.
Manufactured using imported high-density woven polypropylene infused with carbon-black UV inhibitors. Reinforced with 8-row precision V-ring stitching using anti-rot hydrophobic polyester threads, maintaining structural tensile strength over 1,500 N per 5cm under continuous solar radiation.
Innovation Spotlight: Tool-Free Quick-Assembly Architecture
Addressing global consumer pain points regarding tedious installation, Zhejiang Lingsha Technology developed a patented interlocking pin connector system. This design eliminates frame bolt assembly friction while maintaining structural rigidity, reducing end-user setup time by 45% without compromising safety.
Tailored Engineering Solutions for Diverse Global Markets, Climates, and Commercial Ecosystems.
Designed for seasonal weather extremes (freezing winter freeze-thaw cycles and hot UV summers). Featuring curved safety poles with 10mm impact-absorbing EPE foam and heavy-duty ground anchor kits to withstand severe gale forces up to Category 8 winds.
Heavy-duty, high-throughput configurations scaled up to 16FT round or 8x11FT rectangular formats. Utilizing dual-entry self-closing safety enclosures, reinforced spring cover pads, and tamper-resistant frame latches for high-traffic public use.
Silent rebounding technologies featuring high-tensile elastic bungee cords in place of metallic springs. Ideal for indoor 55-inch toddler units and 51-inch T-bar adjustable fitness rebounders tailored for urban apartments and boutique gyms.
Direct Transparency into Our Metalworking, Sewing, Assembly, Packaging, and QC Audit Workflows.
Equipped with fully automated CNC pipe cutters, precision hydraulic benders, and robotic welding stations to ensure flawless seam integrity and dimension consistency across all steel frame elements.
Industrial heavy-duty sewing lines run 8-row PP mat stitchings, custom enclosure net hem weaving, and dynamic drop-test cardboard packaging to guarantee pristine arrival at destination ports worldwide.
Every production batch undergoes strict random sampling audits. Our QA engineers execute tensile load limit stress tests, 500-hour accelerated salt-spray rust tests, zipper fatigue tests, and drop-impact simulations to ensure 100% compliance with ASTM F381-16 and EN71-14 standards.
