The use of plastic to replace wood and plastic to replace steel is the development trend of fishing boat production, and it is also a major change in the world of materials. With the continuous development of the rotomolding process, more and more hull products are selected to be manufactured by rotational molding, so what are the advantages of the hull produced by the rotomolding process?
What are the advantages of rotomolding vessels:
The biggest advantage of the all-plastic rotomolding ship is safety. Since the specific gravity of polyethylene is lower than that of water, the all-plastic ship will not sink even if it is overturned. The crew of the falling water can climb or climb to wait for rescue. The rotomolding hull adopts one-time rotomolding molding, and there is no adhesion, which can always avoid leakage and damage.
At the same time, the all-plastic ship has strong corrosion resistance and is very environmentally friendly. The hull can be completely recycled. Through recycling, it will become a new ship. It will not cause sea pollution when the traditional wooden or FRP ship is sunk or abandoned.
Again, the maintenance cost of plastic boats is very low. The wooden fishing boat generally needs two years of maintenance, and the steel fishing boat will be extensively maintained in three years, and the maintenance cost is large. The rotomolding vessel does not have maintenance problems, and there is no rust, paint peeling pollution, and the hull is firm, and the new boat is built for a short time. For example, a 10-meter-long rotomolding vessel can take only half a day to build a hull. Even if the internal construction of the hull is fully installed and delivered, it can be completed in 3 days.
