| Defects | Causes | Solutions |
| Pearly luster appears on the product and the gate part on the bottom deviates the center | 1The heating temperature for the pre-form is too low | Raise heating temperature |
| 2Blowing time is too early | Prolong the blowing time | |
| 3Heating of pre-form is not uniformed | Check if the rotating electric motor of the oven works | |
| 4The linear velocity for pulling pre-form is too low | Raise working pressure flux of pre-forms | |
| The product can’t be formed | 1 Insufficient pressure | Raise pressure |
| 2Insufficient blowing flux | Raise blowing flux | |
| 3Stretching rate is too high | Redesign stretching rate | |
| 4Blowing valve is damaged | Replace the valve | |
| Wall thickness of products is not uniform | 1Wall thickness of pre-forms is not uniform | Replace pre-forms |
| 2Stretching rate is too low | Redesign stretching rate | |
| The neck of the product shrinks into a loop | Blow time is too late | Advance blowing time |
| The bottom of the product does not form or is too thick | 1Blow time is too late | Advance blowing time
|
| 2 Heating temperature on the bottom of pre-forms is too low | Raise corresponding heating temperature | |
| Transparency of products is not good | 1The pre-form is not transparent enough | The plastic material is not dry enough |
| 2The second-time heating temperature for the pre-form is too high | Reduce the heating temperature and heating time | |
| 3There is moisture in the blowing air | Check if filter outlet is obstructed. |
