What are some common issues in the filling and sealing process?
26-01-14
Common issues in the filling and sealing process mainly include leakage, deviation in fill volume, damage to bottle bodies, inaccurate dosing, inadequate sealing, burnt ends, and blistering.
I. Leakage Issue
Reasons: Uneven sealing pressure, minor defects on the bottle mouth, and aging of equipment seals.
Solution recommendations: Select a filling machine equipped with precise pressure-control functionality, regularly inspect and replace aged seals, and install bottle-body detection devices.
II. Capacity Deviation
Reason: Equipment without precise quantitative functions relies on manual adjustment, resulting in unstable filling volumes.
Solution suggestion: Use equipment equipped with a high-precision quantitative filling system, with error control within ±1 ml.
3. Bottle damage
Reason: There is a mismatch between the conveyor track and the bottle-clamping device. Conveyor tracks with fixed spacing or bottle-clamping devices made of overly rigid materials are prone to causing damage.
Solution suggestion: Choose equipment with adjustable conveyor track spacing, use bottle-clamping devices made of flexible materials, and appropriately adjust the production speed.
4. Inaccurate dosage
Cause: Improper control of the infusion rate and loosening of the screw on the dose adjustment device.
Solution suggestion: Use equipment equipped with a high-precision quantitative filling system and regularly inspect the dose adjustment mechanism.
5. Poor sealing
Reason: The sealing operation was not performed according to standards, and the intensity of the fusion-sealing flame was insufficient.
Solution suggestion: Use a filling machine equipped with precise pressure-control functionality and standardize the sealing operation.
Six, scorched head
Reason: The medicinal solution adhered to the neck of the ampoule and carbonized upon heating. Additionally, the solution was filled too rapidly, causing splashes that stuck to the inner walls of the ampoule neck.
Solution suggestion: Improve operational procedures, adjust equipment operating conditions, and prevent the liquid medicine from splashing.
7. Bubbling
Reason: Air was not fully expelled during sealing, or the temperature was too high, causing the flame to be too intense and leading to evaporation of the liquid medicine.
Solution suggestion: Standardize the sealing operation and appropriately adjust the flame temperature and heating time.
