What technical processes of injection mold molding will affect product accuracy?
When producing some important injection molded parts that require more precise dimensions, the allowable fluctuation range of the size of each part is very small, and even requires only one or two wire fluctuations. So, in the injection molding technology and process, what are the reasons that affect the product accuracy?
In the production process, the main factor that usually affects the dimensional accuracy of injection molded parts is the shrinkage rate of injection molded parts. The greater the shrinkage, the worse the accuracy. So how to change the shrinkage rate?
The shrinkage rate of the injection molded parts can be reduced by adjusting the machine, so as to achieve the purpose of improving the dimensional accuracy of the injection molded parts. We only need to greatly increase the time and pressure of injection or pressure holding to reduce the shrinkage of the injection molded parts, the shrinkage rate is significantly reduced, and the dimensional accuracy can naturally be improved.
In order to ensure the dimensional accuracy of the injection molded parts, the accuracy of the mold is the first condition that needs to be guaranteed, and it is more important to choose a stable and reliable injection molding machine with sufficient pressure for production.
