First, the fiberglass tube has bubbles:

the reason: 

1. The paint concentration is too high and the paint temperature is too high;
2, the machine speed is too fast;
3. Machine failure;
4, the original rubber quality is abnormal;
5. Tooling is not suitable;
6. The lacquer is severe and the air bubbles inside the tube.
Second, the inner diameter of the glass fiber tube is small (large):

the reason:

1. The tooling is improperly used, worn, dirty, and there are debris in the hole;
2. The blank tube weave is abnormal;
3, flat tube;
4. Machine drive failure.
Third, the voltage is not enough (stable):
the reason:

1. The paint concentration is too low;
2, bubble out;
3, the original rubber quality problems;
4. The blank tube is poorly woven, too loose and loose;
5. The staff is operating incorrectly.
Fourth, the fiberglass casing color is uneven:

the reason:

1. The dewaxing temperature setting is not appropriate;
2. Dewaxing temperature is unstable;
3. The outside cold air enters the dewaxing furnace;
4. The blank tube is weaved abnormally.
5. The glass fiber tube has particles:

the reason:

1. The paint has not been filtered;
2. The paint bucket is not cleaned for a long time;
3. The quality of the original rubber is abnormal;
4. The guide wheel is not clean and there is hard glue stained on the blank tube.
Sixth, glass fiber tube stains:

the reason:

1. The former process is caused;
2. The billet at the billet is contaminated with water stains, oil stains or other contaminants;
3, cross color;
4. Mopping the floor with dust or other debris;
5, the paint is not clean, there are sundries or mixed with other colors.
Seven, the wall thickness does not meet the requirements:
the reason:

1. The blank tube weaving is not satisfactory;
2. The inner hose is not required to be extruded or the extruded wall thickness is unstable;
3. The paint concentration is not appropriate;
4. The machine speed setting is inappropriate or unstable.
