Mold Injection of the hot plastic material is the most often used procedure to produce plastic parts. This procedure involves the injection at high pressure of the plastified material in the cavity of a mold where it cools and will become solid.
The injection process has the advantage of repeatability, of high yield rate of production, plastic parts with high complexity of the shape, reduced costs of production comparing with other types of plastic part production.
By the nature of the production process, The mold in which the part is formed supports high pressure loads. For this reason in the mold construction process should prevent the deformations, the ware caused by the big number of injection cycles.
To obtain productivity, should focus on better thermal control to increase solidification rate in the mold .
