① Shorten the opening stroke of the injection mold to the minimum necessary so that the parts and runners fall off;

② Exclude any factors that make ejection difficult, such as the flashing edge around the ejector pin.

③ shorten the ejection stroke to the necessary minimum;

④ Use the fastest mold opening and closing speed, and at the same time, stop and close appropriately to prevent damage to the injection mold;

⑤ Look for any delays in mold closing and clamping pressure, which indicate failure of mechanical or hydraulic valves;

⑥ A large number of insert activities in the injection mold also increase the opening time of the injection mold. A little consideration of product design (reduction of undercuts) can often make the ejection action automatic or semi-automatic;

⑦If the delay is caused by the loss of the injection mold, the mold should be repaired to reduce the delay;

⑧ Developing good operating habits of injection molding machines is of great benefit to improving machine life and production safety.
