The cause -When a product line focused, often forcing the gas to a place cause air bubbles in it. -Throughout the process fill the mold, the air is retained in the products in these regions fill out product after all. Remedy -Thickness product design in the proper position. -The position of the gate. -Reduce the injection speed, because if sprayed at high speed, the gas does not escaped. -However, we must first exhaust system optimization, then new to reduce the injection speed. -Loss of pressure or the pressure reduction screw by reducing speed (especially when air bubbles are formed right near the gates of the spray). -If there are air bubbles, you need to put them into the easy escape of gas or more tiny light bars on the gas to escape.
