Explore our enterprise-grade outdoor trampoline models built to international safety standards (ASTM, EN71, GS, AS4989).
Pioneering Next-Generation Trampoline Engineering, Safety Innovations, and Global Supply Chain Excellence under the "Funjump" Brand
At Zhejiang Lingsha Technology Co., Ltd. (operating globally under the premier manufacturing brand Funjump), we are committed to engineering safe, high-performance, and structurally stable outdoor trampolines. Our core capabilities span custom manufacturing of high-capacity outdoor trampolines, commercial recreation jumping beds, indoor fitness rebounders, and specialized children's play structures. Designed for multi-demographic engagement—spanning children, teenagers, adults, and professional fitness enthusiasts—Funjump products harmonize leisure with robust kinetic safety.
To uphold strict international standards, our enterprise maintains rigorous certification compliance including ISO9001, BSCI, GS (Geprüfte Sicherheit), EN71-14, ASTM F381/F2225, and AS4989. Operating from an expansive, modernized manufacturing footprint covering 68,000 square meters, our facilities are staffed by over one hundred highly skilled engineers, technical operators, and QA specialists. Funjump's state-of-the-art facility features an in-house specialized trampoline safety testing laboratory, automated robotic welding stations, precision multi-needle computer sewing systems, and high-velocity automated packing lines—delivering an aggregate production output exceeding 1,500 complete trampoline sets daily.
Inside Zhejiang Lingsha Technology's automated production floors: metalworking, sewing, assembly, and warehousing precision.
Utilizing CNC tube-bending machinery, double-sided hot-dip galvanizing lines, and robotic laser welding stations. Our frame steel walls range from 1.2mm to 2.0mm thick, ensuring high torsional stiffness and rust resistance during long-term outdoor exposure.
Equipped with heavy-duty computer-controlled multi-needle sewing machines. Our UV-resistant polypropylene jumping mats are sewn with 8-row reinforced V-ring stitching using high-tenacity polyester threads, mitigating tear risks under heavy dynamic loads.
Standardized drop-test approved 5-layer corrugated export cartons with customized inner foam padding. Automated barcode scanning ensures 0% missing-part rates for complex multi-box OEM/ODM orders shipped worldwide.
How Funjump advances the state-of-the-art in recreational dynamics, kinetic energy absorption, and long-life polymers.
Traditional outdoor trampolines suffer structural fatigue at frame weld joints. Funjump resolves this with our patented T-Section Interlocking Connector System. By eliminating direct load-bearing welds at stress hotspots, our cold-rolled steel frames distribute kinetic energy evenly across the perimeter legs.
The heart of a high-performance bounce lies in spring calibration and fabric elasticity. We use high-tensile 60Si2Mn spring steel engineered with a conical coil geometry that provides a smoother, deeper rebound curve while minimizing dynamic strain on user joints.
Over 70% of outdoor trampoline injuries stem from spring contact or enclosure netting failures. Funjump integrates a direct-sewn net connection mechanism that connects the safety enclosure directly to the jumping mat's V-rings, completely sealing off access to the spring bed.

| Jumping Mat UV Resistance | Standard PP (Fades & degrades within 1,000 hrs) | 260g/m² Grade-A PP with 5,000 hr UV protection rating |
| Safety Net Attachment | Outer rope tie-down (Leaves spring gaps) | Zero-Gap direct V-Ring interlock system |
| Max Dynamic Load Weight | 80 kg - 100 kg total limit | 150 kg - 180 kg static/dynamic certified load rating |
Tailored OEM, ODM, and White-Label Solutions designed for B2B Importers, Retail Chains, E-Commerce Leaders, and Commercial Play Operators.
We partner with major e-commerce brands—including top-tier sellers on Amazon, eBay, and Walmart. We offer specialized ISTA-6A drop-test certified mail-order packaging, fast toolless assembly designs (such as our quick-disassembly mini and foldable fitness models), and custom branded instruction manuals.
For big-box brick-and-mortar retailers requiring mass bulk volumes, we deliver full-container load (FCL) efficiency. Multi-size SKU consolidation (e.g., 8ft, 10ft, 12ft, 14ft, 16ft round and rectangular units) allows optimal container space optimization with palletized floor loading.
High-duty usage environments require extra safety margins. Our heavy-duty commercial outdoor models feature reinforced double-truss legs, 2.0mm thick frame tubing, and ultra-high-grade padding designed for public parks, summer camps, resorts, and physical education hubs.
Size Options: 4X6FT, 55", 6FT, 8FT, 10FT, 12FT, 14FT, 16FT round, or 6x9FT, 7x10FT, 8x11FT rectangular formats.
Color Customization: Safety pad PVC sleeves (Blue, Black, Green, Pink, Camo, or multi-tone custom Pantone branding).
Accessory Add-ons: Integrated basketball hoops, water sprinklers, LED light strips, shoe bags, ladder systems, and ground anchor kits.
Every Funjump trampoline undergoes rigorous multi-stage quality assurance testing before leaving our facility.
Compliance with regional safety mandates is paramount for international trade. Zhejiang Lingsha Technology maintains dedicated compliance officers who continuously update product designs in accordance with revised safety standards:
Full adherence to structural integrity tests, frame stability under tilt, enclosure netting impact resistance, and warning label placements mandated by U.S. and Canadian regulatory bodies.
Comprehensive mechanical property verification, non-toxic material testing (REACH, Phthalates, Heavy Metals), and GS TÜV Rheinland certified factory audit credentials.
Severe weather UV resistance testing and high-impact structural testing optimized for Oceania's extreme outdoor solar radiation conditions.
Clear, transparent answers to commercial, procurement, and structural engineering queries.
Explore our broader range of toddler mini-jumpers, indoor fitness rebounders, and large outdoor family trampolines.
The true meaning of (Zhejiang Lingsha Technology Co., Ltd.) Funjump is to enable every customer using our trampolines to experience pure joy, health, and total peace of mind. Trampolines are not merely outdoor toys for children—they offer adults, families, and fitness enthusiasts a powerful avenue for physical wellness, cardiovascular conditioning, and happiness.
