Founded in 2019, Shenghuang Industrial & Trade Blow Molding Factory has established itself as an elite pioneer in the plastic blow molding sector. Headquartered in Huangyan, Taizhou, Zhejiang province—a world-renowned hub for state-of-the-art mold design and advanced manufacturing infrastructure—the enterprise designs, engineers, and fabricates heavy-duty industrial plastic installations. Over the years, we have transitioned from regional component tooling to global contract manufacturing for high-impact marine infrastructure, logistics packaging, custom automotive parts, and robust environmental systems.
Operating from a purpose-built facility, Shenghuang manages high-capacity blow molding machinery capable of generating ultra-thick walls (6mm to 8mm) using high-molecular-weight High-Density Polyethylene (HDPE). This focus on technical excellence enables us to provide commercial-grade OEM Jetski Ramps, U-shaped and V-shaped modular floating docks, and custom components for marine infrastructure operators across five continents.
Our proximity to Ningbo and Shanghai ports combined with Taizhou's extensive local mold engineering supply chain means product-development-to-production times are reduced by up to 35% compared to other industrial zones.
The global demand for reliable personal watercraft (PWC) docking solutions has surged, fueled by the expansion of waterfront developments, tourist resorts, and private marine properties. At the center of this growth is the need for durable, low-maintenance, and easy-to-use docking systems. OEM Jetski Ramps manufactured via high-pressure blow molding have emerged as the industry standard due to their outstanding strength-to-weight ratio, chemical resistance, and long-term reliability.
At Shenghuang, we formulate our dock cubes and PWC ramps using premium High-Density Polyethylene (HDPE) blended with proprietary UV inhibitors and stabilizers. Unlike timber docks that decay or aluminum ramps that corrode, marine-grade HDPE is resistant to chemicals, saltwater, and gasoline.
Our blow-molding process maintains material integrity, ensuring high impact resistance even in extreme temperatures (-60°C to +80°C). By choosing a high-molecular-weight raw material, our structures handle dynamic stress and frequent impacts from watercraft hulls without cracking.
A key challenge for PWC launching systems is managing the transition from water to ramp. Our U-shaped and V-shaped floating docks feature a molded entry pocket that centers the jetski hull as it approaches the ramp. The concave-convex surface pattern provides slip resistance for operators walking around the platform.
Integrated rollers or low-friction guide strips can be added to the OEM designs. This setup reduces friction, allowing operators to launch and retrieve watercraft with minimal throttle or winch power, protecting the PWC hull from scratches and wear.
Our Taizhou factory operates an in-house mold shop. We customize load distributions, overall lengths, connecting pin systems, and structural ribs to match your specific commercial project requirements.
We incorporate high-grade UV-15 stabilizers into our HDPE compound to protect against intense sun exposure, preventing fading, chalking, and structural degradation in tropical marine environments.
Our production lines run under a certified ISO 9001 quality management system. Every batch of HDPE raw material is tested for melt flow rate, and completed dock sections undergo strict pressure and load tests.
Procuring directly from a primary manufacturer like Shenghuang in Zhejiang offers significant advantages for global distributors, marine construction companies, and commercial marinas.
Our automated blow molding lines run continuously, lowering per-unit production costs. This efficiency allows commercial marine developers to maximize their budgets, especially when compared to local distributors who add retail markups.
As a true OEM partner, we do more than just sell stock products. We work with clients to design customized docking solutions. Whether you need a specific color, custom anti-slip textures, or unique connecting features, our engineering team can develop and build it.
Located near Ningbo and Shanghai ports, we handle complex international logistics. We consolidate shipments, optimize container space to reduce shipping costs, and prepare all export paperwork for customs clearance.
We employ a dedicated team across sales, engineering, and quality control, ensuring every client receives professional support and prompt service from start to finish.
Our flexible R&D setup allows us to quickly design and manufacture custom products to meet specific regulatory requirements and unique client specifications.
We invest in energy-efficient machinery and use recyclable raw materials, combining advanced manufacturing technology with eco-friendly production practices.
Our dedicated support team assists with pre-sales layout planning, shipping consolidation, import compliance, and step-by-step installation guidance.
Floating Dock's modular design and superior quality hold up quite well in a typhoon depending on the installation. Our customers are reporting excellent results for the docks that were hit hand in all the typhoon.
Yes, In the areas where there is not a local dealer presence, we can ship your Floating Dock system directly to you local freight terminal for pickup.
Absolutely, The dock can be left in all year even in salt water. The Floating Dock system is designed to be left in the ice for the winter. The special design of the cube allows the dock to pop up on top of the ice.
The issue when it comes to ice and its affect on the system is water flow. If there is a heavy current or moving ice, the key question to ask yourself is, "When the ice thaws out, does it just dissipate back into the water level or are there large blocks of heavy flow ice moving around that would severely damage stationary docks?" If you answer "Yes" to the first part of the question, you can leave our dock in all year. If you answer "Yes" to the second part of the question, then your next move is as obvious as the ice will tear out and wash away any structure.
The cubes can be used as a floating platform, gangway, finger pier or any other type of customized configuration you so desire. Available walking platform must be at least three cubes wide . The dock is extremely stable to walk on and will support your body weights due to the balanced buoyancy of each cube(which is about 200 lbs).
Yes, you can use the dock anywhere you can drive your crafts. The cubes only draw about 2 to 4 inches of water with the craft off it. The minimum functional water depth is measured at the back of the dock where the drive-on takes place. The dock needs to be able to flex in order to drive on top of it. System is fine at rest on the bottom during low tides. The important thing is that there is enough depth at the stem of the dock to allow the boat to back off.
Our factory start our floating dock business from year 2019, is one of the earliest floating dock manufacturer in China. floating dock is becoming the largest floating dock supplier in China, offer the super quality floating dock products.
Yes, we provide full OEM branding services. We can add corporate logos directly into the blow molds to create permanent embossed branding. Custom colors can also be formulated for bulk orders of 500 units or more, ensuring your docks align with your company's visual identity.
