Automotive | The types of plastic injection molds are:Injection mold is also called injection mold. The molding process of this mold is characterized by placing the plastic material in the heating barrel of the injection machine. The plastic is heated and melted, and driven by the screw or plunger of the injection machine, it enters the mold cavity
Die casting is a precision casting method that uses high pressure to force molten metal into a metal mold with complex shapes. It is characterized by using the cavity of the mold to apply high pressure to the molten metal. Molds are usually machined from stronger alloys, a process somewhat similar to injection molding. Most die castings are iron-fr
The easiest way to increase engine power is to increase the working volume of the cylinder, that is, increase the displacement. Generally speaking, increasing the workload will increase the volume of the engine, and the weight will also increase. This approach is unacceptable to modern passenger vehicle designers looking for compactness and driving
