Engineered to exceed ASTM F381-16, EN71-14, and AS4989 global structural standard requirements.
In the global play equipment and outdoor physical activity sector, product longevity, structural safety, and rapid customization are paramount. Zhejiang Lingsha Technology Co., Ltd. (Brand: Funjump) operates at the nexus of advanced structural engineering and mass-scale OEM/ODM production. As an authoritative Custom Trampoline And Swing Set Manufacturer & Factory, Funjump maintains a centralized manufacturing complex spanning over 68,000 square meters, powered by automated production pipelines, robotic welding units, and an enterprise workforce exceeding 100 specialized engineering and assembly professionals.
With an established daily throughput exceeding 1,500 full trampoline systems, our operational model bridges high-capacity output with granular custom specifications. We fulfill structural, aesthetic, and mechanical requirements across indoor and outdoor recreational formats, fitness rebounders, and integrated multi-play swing set systems. Our infrastructure is certified under international standards including ISO9001, BSCI, GS (Geprüfte Sicherheit), EN71-14, ASTM F381/F2225, and AS4989.
Our 68,000 square meter factory contains segregated automated metallurgy workshops, precision high-speed textile stitching units, automated electrostatic powder coating lines, clean-room packaging zones, and comfortable staff quarters. This fully integrated ecosystem guarantees total oversight over raw material handling, structural fabrication, and packaging resilience.
Funjump houses an internal Trampoline Safety Testing Laboratory equipped with dynamic impact simulation rigs, tensile spring fatigue testers, UV degradation weatherometers, and salt-spray corrosion chambers. Dedicated quality control inspectors monitor every production batch to eliminate structural defects prior to shipment.
How Funjump engineered zero-tool quick-assembly mechanisms and high-tenacity frame architectures without compromising structural rigidity.
A persistent operational friction point for commercial distributors and direct consumers is the complexity of trampoline assembly and seasonal storage. Traditional designs rely on rigid bolted joints and manual spring pullers, introducing high labor times and potential joint shear risks under off-center dynamic loads. Adding movable parts or quick-release connectors typically introduces frame wobble, decreasing structural stability.
Through Finite Element Analysis (FEA) and dynamic stress mapping, Funjump’s engineering division developed a patented Quick-Disassembly Snap-Lock Connector and Foldable Fitness Frame Architecture. By utilizing precision-swaged structural steel tubing and self-locking pin joints, our foldable mini trampolines and full-size outdoor frames can be erected or packed down in minutes with minimal tooling. Structural integrity is preserved via interlocking T-sections that distribute kinetic impact vectors across the entire perimeter frame.
We utilize heavy-duty hot-dip galvanized steel tubing (both internal and external corrosion barrier) with minimum 1.5mm to 2.5mm wall thickness. Zinc application exceeds 120g/m² to prevent inner tube degradation caused by trapped moisture.
Our high-tensile carbon steel springs undergo heat treating and specialized zinc plating. Engineered with tapered waist geometry, they deliver smooth deceleration curves and achieve over 50,000 fatigue cycles under continuous max-load testing.
Jumping mats are manufactured using 260g/m² high-density polypropylene (PP) imported woven fabric featuring carbon-infused UV protection. Mat perimeter V-rings are reinforced with 8 rows of heavy-duty cross-stitch polyester thread.
