When we understand the function of plastic parts, we need to pay attention to its advantages and disadvantages. In fact, it is a very important problem for the anti internal stress. If it is very easy to crack in the low temperature state, it is not guaranteed in the quality, especially for the mold design of the surface. The processing technology.
In fact, for the size of the processing pressure, the speed is also restricted and restricted, in addition to the state of pressure protection, the plastic parts in the application process, need to pay attention to whether to die and crack, especially for the pressure design, also should take into account the strong pull parts, and the speed of it. It is said that the degree of cracking is also very large if the holding period is too long.
