Direct Factory Wholesale & Custom OEM/ODM Large Outdoor & Indoor Trampoline Systems
Zhejiang Lingsha Technology Co., Ltd. (Funjump) — Strategic Manufacturing Partner for Global Trampoline Brands
Zhejiang Lingsha Technology Co., Ltd. (Funjump) is committed to manufacturing safe, durable, and highly stable trampolines for international procurement markets. We engineer customized trampolines ranging from small indoor toddler units to 16ft large outdoor recreational and commercial rebounders. Our brand philosophy centers around giving every user a joyful, safe jumping experience under rigorous structural protection.
Spanning over 68,000 square meters of modern industrial park, our plant houses over 100 skilled technicians, automated tube-bending machines, high-precision robotic welding lines, and automated sewing units. Operating multiple streamlined production tracks, our daily output exceeds 1,500 sets of trampolines, supplying major cross-border e-commerce brands (including Amazon Top Sellers) and international retail chains.
Equipped with an specialized in-house trampoline testing laboratory, we perform rigorous structural fatigue, spring tensile stress, UV degradation, salt spray anti-corrosion, and dynamic drop testing. Our internal quality control inspectors eliminate potential manufacturing flaws before shipment, ensuring absolute safety for end consumers worldwide.
Why Tier-1 Global Procurement Directors Partner with Zhejiang Lingsha Technology Co., Ltd.
B2B Technical Insight: The lifespan and safety of a large outdoor trampoline depend on frame steel thickness, anti-corrosion chemical treatment, spring elastic fatigue resistance, and polypropylene (PP) mat weave density. Funjump integrates China’s most robust industrial raw-material ecosystems with precision metalworking to yield market-leading safety margins.
We utilize high-grade Q195/Q235 steel pipes featuring double-sided hot-dip galvanization (internal and external wall thickness ranging from 1.5mm to 2.0mm). This structural framework passes a 500-hour neutral salt spray test (ASTM B117), guaranteeing resistance to rust, oxidation, and structural collapse even under extreme coastal atmospheric conditions.
Our jumping mats are constructed from premium 260g/m² Permatron Polypropylene (PP) material integrated with high-concentration carbon black. The perimeter connection uses 8-row precision stitching with reinforced UV-resistant polyester thread, preventing tears along the dynamic load points holding heavy-duty V-rings.
Funjump trampolines utilize waist-drum tapered springs fabricated from 70# high-carbon steel wire. Unlike standard cylindrical springs, tapered springs distribute dynamic tensile strain evenly, providing a smoother bounce curve, reduced deceleration impact on jumpers' joints, and over 100,000 continuous compression cycles without permanent deformation.
| Component Specification | Funjump Industrial Standard | Generic Market Alternative | Engineering Benefit |
|---|---|---|---|
| Steel Pipe Coating | Internal & External Hot-Dip Galvanization | Single-sided Cold Spray Paint | Prevent internal tubing corrosion & rust failure |
| Enclosure Net Fabric | 120g/m² High-Density PE UV-Shield Netting | 80g/m² Recycled PVC/Polyester Net | 3x higher resistance to tear and sun brittleness |
| Frame Foam Padding | 20mm EPE Closed-Cell Foam + PVC Cover | 10mm Thin Sponge + PE Cover | Waterproof protection, impact absorption |
| Perimeter Stitching | 8-Row Heavy-Duty Reinforced Stitching | 4-Row Standard Stitching | Prevents mat detaching from V-rings under load |
Fulfilling Strict International Import Protocols Across North America, Europe, and Australia
Compliant with mandatory US Consumer Product Safety Improvement Act (CPSIA) rules. Structural tests evaluate frame stability, impact dissipation, enclosure height containment, warning label permanency, and non-toxic heavy metal thresholds in paint coatings.
Certified for European safety standards (EN71-14). Rigorous checks include finger/limb entrapment prevention, edge padding shock absorption, structural integrity under static load overloads, and chemical safety (REACH & Phthalate compliance).
Constructed to withstand intense UV index levels in Oceania. Enclosure nets and safety padding undergo extended artificial weathering tests to prevent premature structural breakdown from heat and sunlight exposure.
Zhejiang Lingsha Technology Co., Ltd. operates under audited Business Social Compliance Initiative (BSCI) and ISO9001 Quality Management Systems, ensuring ethical manufacturing, transparent human resources, and reliable batch traceability.
Tool-Less Quick Assembly & Space-Saving Foldable Trampoline Technology
Historically, assembly complexity and tedious spring tensioning have been major causes of customer dissatisfaction and e-commerce product returns. Standard outdoor trampolines require hours of manual strain, specialized tools, and multi-person assembly effort.
Through continuous R&D feedback cycles, Funjump engineers developed a series of quick-connect frame joints and foldable fitness trampolines. By developing pre-assembled snap-lock modules and heavy-duty hinges, users can set up or collapse their trampoline without sacrificing frame stability or jumping safety.
Commercial E-Commerce Impact: Implementing our quick-assembly and compact folding structural designs has lowered product return rates for key Amazon sellers from 8.5% down to under 1.2%, significantly improving store ratings and profit margins.

Tailored Manufacturing for Global Retail Brands, Distributors, and E-Commerce Merchants
We manufacture a wide range of form factors including standard round trampolines (6ft, 8ft, 10ft, 12ft, 14ft, 16ft) and custom rectangular trampolines (6x9ft, 7x10ft, 8x11ft). Oval, hexagonal, and mini-rebounders are fully customizable to meet specific regional sales demands.
To prevent transit damage and excessive freight costs, we offer ISTA 3A / ISTA 6-Amazon certified drop-test packaging. Compact 5-ply corrugated mail-order cartons optimize container loadability (CBM), maximizing units shipped per 40ft HQ container.
Elevate your brand presence with custom screen-printed logos on jumping mats and frame pads, custom carton graphics, color-matched enclosure poles, and bundled accessories like basketball hoops, ladders, shoe bags, and anchor kits.
