Small scale is easy to solve, but the scale is 10 times and the difficulty is 10 times. Suction is a mature process, and the manufacturing of fairing is easy. It's just that the cost is proportional to the volume. I asked a friend who is a plastic factory, a small fairing with the size of 60X60X30, the mold cost is 3000, but the cost of each production is only 100. If the output cost is only 365,438+000, then 400 yuan, 65,438+000 yuan is cheaper. For example, the cover imported by Chivalrous Man is twice as large as this one, with at least 6,000 molds. As for the totally enclosed shell 250X 100X60, there are 40,000 sets of plastic molds (excluding design cost), and one shell consumes about10-15kg of plastic raw materials. If it is ABS, the cost of raw materials will be more than 300. It's expensive to produce one, just like those shells that took part in Honda's energy-saving competition. Tens of thousands are normal. Finally, the cost of FRP mold is relatively low, because the basic mold materials of FRP mold are widely selected and the processing methods are diverse. For molds with low requirements, the cost of such a large scale is about 6.5438+0 million, which is very suitable for manual production. These are large equipment in front of plastic suction, and DIYER is basically hopeless. This is the result of my research before I made the shell.
