Reasons and solutions for sagging in mobile phone spray painting:

Reason: Excessive diluent causes the paint viscosity to be too low, resulting in loss of stickiness; The oil output is too large, too close to the surface, or the spraying operation is too slow; Too much fuel injection each time or too thick or too short interval between re injections; Uneven surfaces, especially streamlined shapes that are prone to vertical flow.

Solution: Mix according to requirements; Control the oil output to ensure that the spray gun operates at a faster speed than before; It is not advisable to spray too thick each time, and it is best to control the interval between spraying in two batches; Control the oil output and reduce the thickness of the paint film; Mix according to the instructions for use.
