　　The screw of the injection molding machine can reach the set melt adhesive stroke, but cannot reach the set injection molding stroke (with residual adhesive amount). This situation means that there is glue in the barrel, but it cannot enter the mold cavity. Possible causes:

　　1. The fluidity of the melt adhesive is insufficient.

　　The fluidity of the melt adhesive is insufficient, the flow resistance is high, and the colloid is difficult to fill into the mold. This situation may also be caused by the following reasons:

　　a) The flowability of the raw materials themselves is poor;

　　b) The processing temperature of the barrel is set too low or the temperature has not reached the set value, such as inaccurate temperature display.

　　c) The mold temperature is low. Although the colloid in the barrel has good fluidity, it cools down too quickly after flowing into the mold channel, resulting in poor fluidity in the mold cavity and insufficient filling of the colloid.

　　2. Improper setting of injection molding process parameters.

　　The injection pressure is low, and the colloid cannot overcome the filling resistance; Low injection molding speed, long cooling time of adhesive glue during filling, reduced fluidity, resulting in high filling resistance; Short injection molding holding time and stopping filling before the product is fully filled can all lead to insufficient adhesive.

　　3. The filling channel is blocked.

　　Due to the blockage of the filling channel by cold glue, impurities, or other substances, the filling cannot be completed, which can also result in the product not being fully filled with glue. At this point, it is necessary to check whether the injection nozzle, main channel, branch channel, gate, etc. of the injection molding machine are unobstructed. If there is any blockage, it needs to be cleaned thoroughly.
