The main reasons for insufficient filling are as follows:
1) insufficient resin capacity.
2) insufficient pressure in the cavity.
3) resin fluidity is insufficient.
4) poor exhaust effect.
As an improvement measure, we can start from the following aspects:
1) lengthen the injection time to prevent the resin countercurrent before the gate solidification due to the short molding cycle, which makes it difficult to fill the mold cavity.
2) improve the injection speed.
3) increase the mold temperature.
4) increase the resin temperature.
5) increase injection pressure.
6) enlarge gate size. Generally, the height of the gate should be equal to 1 / 2 to 1 / 3 of the wall thickness of the product.
7) the gate is set at the place with the largest wall thickness of the work in progress.
8) set the exhaust slot (average depth 0.03mm, width 3-smm) or exhaust rod. It is more important for smaller workpieces.
9) there is a certain buffer distance (about SMM) between the screw and the injection nozzle.
10) select low viscosity materials.
11) add lubricant.
