MINI AUDIO FRONT COVER INJECTION MOLD DESIGN

With the continuous development of economy and industrial product technology, all walks of life demand more and more moulds, technical requirements are also getting higher and higher. Therefore, some important mold standard parts must also focus on the development, but its development speed should be faster than the mold, so as to improve the level of China's mold standard, so as to improve the mold quality, shorten production cycle and reduce the cost of. The plastic shell has the advantages of light weight, suitable for multi products, corrosion resistance aging, high strength, long service life, convenient manufacture, low price and other characteristics, is the ideal substitute of aluminum, iron, plastic industry is the inevitable development of the injection molding is the main method of forming thermoplastic parts, so a wide range of applications. The plastic injection molding is the raw material into the barrel through the heating and melting, making the high viscosity of the fluid, the plunger or screw as pressure tool, cavity melt through the nozzle into the higher pressure in the mold, after cooling, the solidification stage, and then ejected from the mould, a plastic products.  The biggest characteristic of plastic injection molding process is to copy, can reproduce the products required any number can be used directly or after treatment can be used, is a process suitable for mass production. Although the equipment investment is larger, but the number of products can be very large, a kind of economic and efficient mode of production is, therefore obtains the widespread application and rapid development.
