    How was the military quick prototyping model process made at the air show?

    The various military equipment we saw on the air show are actually military equipment models produced by the prototype factory, also known as the prototype. According to the requirements, some of these prototypes will be scaled down according to the prototype in size, but the appearance and structure are basically the same as the prototype, and have some functions of the prototype. Some equipment can also be directly assembled into a real military equipment prototype for operation testing. Why do military equipment need to be modeled? Instead of directly producing products? To understand this problem, we must first understand the…

    Incorrect injection mold temperature

    1.The influence of mold temperature on appearance: Firstly, the mold temperature is too low, which will reduce the melt fluidity and may cause underinjection. Mold temperature affects plastic crystallinity, for ABS, mold temperature is too low, the product finish is low. Compared with fillers, plastics migrate more easily to the surface when the temperature is high. So when the temperature of the injection mold is high, the plastic composition is closer to the surface of the injection mold, the filling will be better, and the brightness and luster will be higher. But the injection mold temperature can not be too…
