Application of blow molding grade ABS in automobile spoiler

For high-speed cars, the spoiler installed at the rear plays a very important role. In addition to being able to bring beautiful decorative effects to the car, more importantly, the spoiler can also effectively reduce the buoyancy of the car at high speeds, ensure the stability of the car, and help save fuel.

Generally, there are 4 kinds of materials that can be used to make car spoilers, including: FRP, aluminum alloy, carbon fiber and plastic. These materials have their own advantages and disadvantages: FRP has high rigidity, low cost, but poor environmental protection, and has been gradually eliminated; aluminum alloy has good diversion effect but heavy weight; carbon fiber has high rigidity and light weight, but expensive; plastic is light, It is beautiful and has great design freedom and easy processing. It is currently the most widely used spoiler material. This article will introduce new ABS materials for spoilers.

At present, the plastic spoiler can be processed by two processes, namely, one-time blow molding and injection welding. Among them, the blow molding process efficiency is high, the mold cost is low, and the post-processing volume is small. Therefore, most of the plastic spoilers are currently produced by blow molding. The production process of the injection welding method is: first injection molding the upper and lower pieces, and then welding the upper and lower pieces together. Although this method is faster in the injection molding stage, it often requires two injection molds, which is expensive. At the same time, the subsequent ultrasonic welding or hot plate welding also requires the cooperation of the molds, so the cost is higher and the overall efficiency is relatively high. Low, rarely used at present.
