Question:

Is the injection pressure tight after the valve pin closes?

Is the injection pressure tight after the valve pin closes?

Answer:

In the process of injection molding, solution and shrinkage because of cooling, but because the screw to move slowly forward, so that the material in the tube to melt into the cavity, to supplement the needs of shrinkage, called pressure. It means to prevent product shrinkage, with pressure if production is stable. The pressure can also adjust the product size, without weld line
