Fiberglass casing is a special fiberglass casing that is woven into a tube with glass fibers and processed through a high-temperature shaping process.

1. There are bubbles in the fiberglass tube:

reason: 

1. The paint concentration is too high and the painting temperature is too high;

2. The machine speed is too fast;

3. Machine failure;

4. The quality of the original glue is abnormal;

5. The work clothes are inappropriate;

6. The paint seepage is serious and bubbles appear on the inner wall of the pipe.

2. The inner diameter of the fiberglass tube is too small (large):

reason:

1. Improper use of tooling, wear and tear, dirty tooling, and debris in the holes;

2. The weaving of the blank tube is abnormal;

3. Flat tube;

4. Machine transmission failure.

3. The voltage is not enough (stable):

reason:

1. The paint concentration is too low;

2. Make bubbles;

3. Raw gum quality issues;

4. The blank tube is poorly woven and too sparse and loose;

5. Employees operate incorrectly.

4. Uneven color of fiberglass casing:

reason:

1. The dewaxing temperature setting is inappropriate;

2. The dewaxing temperature is unstable;

3. External cold air enters the dewaxing furnace;

4. The weaving of the blank tube is abnormal.

5. There are particles in the fiberglass tube:

reason:

1. The paint has not been filtered cleanly;

2. The paint bucket has not been cleaned after being used for a long time;

3. The quality of raw glue is abnormal;

4. The guide wheel is not clean, and hard glue is stained on the blank tube.

6. Fiberglass tube stains:

reason:

1. Caused by previous processes;

2. The billet pipe is contaminated with water stains, oil stains, or other pollutants;

3. Cross color;

4. The mopping floor is contaminated with dust or other debris;

5. The paint is not clean, contains debris, or is mixed with other colors.

7. Wall thickness does not meet requirements:

reason:

1. The weaving of the blank tube does not meet the requirements;

2. The inner hose does not meet the requirements when extruded or the extruded wall thickness is unstable;

3. The paint concentration is inappropriate;

4. The machine speed setting is inappropriate or unstable.
