Problem Performance:Printed text or patterns come off easily, especially after sterilization or long-term storage.
Cause analysis:
The surface of the centrifuge tube is not thoroughly cleaned and adheres to oil or dust.
The ink used is incompatible with the material of the centrifuge tube, and the adhesion is insufficient.
Improper drying time or temperature setting, resulting in incomplete curing of the ink.
Solution:
Perform surface treatment on the centrifugal tube before screen printing, such as cleaning, drying or corona treatment, to enhance the adhesion.
ｓｅｌｅｃｔ the matching ink according to the material of the centrifugal tube (e.g. PP, PE, etc.) and conduct a small-scale test.
Optimize the drying process and adjust the appropriate temperature and time to ensure that the ink is fully cured.
Calibrate the photoelectric positioning system and ｒｅｐｌａｃｅ deteriorated sensors if necessary.
Problem performance: the printing pattern or text is blurred and not aligned, especially when high-precision screen printing on small batches of centrifugal tubes.
Cause analysis:
1. the mechanical parts of the screen printing machine are loose, resulting in inaccurate transmission and positioning.
2. Ink viscosity does not meet the requirements, affecting the clarity of the pattern.
3. The photoelectric positioning system is not calibrated properly, failing to accurately detect the position of the centrifuge tube.
Solution:
-Check the mechanical parts of the equipment regularly and tighten loose screws or other connectors.
-Adjust the ink consistency according to the material of the centrifugal tube and screen printing requirements to ensure its fluidity and adhesion.
-Calibrate the photoelectric positioning system and ｒｅｐｌａｃｅ deteriorated sensors if necessary.
Problem: The equipment generates excessive noise during operation, affecting the working environment.
Cause analysis:
-The internal parts of the equipment are loose.
-Insufficient lubrication of the drive system.
-Motor or reducer failure.
Solution:
-Check and tighten loose parts regularly.
-Add lubricant to the unit's drive system.
-Check the motor and reducer and ｒｅｐｌａｃｅ damaged parts if necessary.
Problem performance: Centrifugal tubes may be stuck, piled up or even derailed during the conveying process, resulting in the equipment failing to operate normally.
Cause analysis:
-The size of centrifugal tube does not match with the track of loading machine.
-The friction coefficient of the loading rail surface is too high or too low.
-Vibration or external interference during loading.
Solution:
-Ensure that the size of the centrifuge tube matches the design of the equipment.
-Clean the track surface regularly to keep it flat and clean.
-Adjust the vibration parameters of the equipment to ensure stable operation.
Problem performance: during the operation of the equipment, the packaging speed is fast and slow, affecting the production rhythm.
Cause analysis:
-Motor or transmission system failure.
-Equipment control program is not stable or the parameters are not set reasonably.
-The material supply system is not uniform.
Solution:
-Inspect and repair the motor and transmission parts, and ｒｅｐｌａｃｅ them if necessary.
-Upgrade the equipment control system or recalibrate the parameters.
-Check the feeding device regularly to ensure its proper operation.
Problem performance: After the packaging is completed, the sealing part is loose or cannot be sealed completely, resulting in product exposure or contamination.
Cause analysis:
-Improper setting of heat sealing temperature or time.
-Dirt or wear on the surface of the heat sealing device.
-Packaging materials with poor heat sealing performance.
Solution:
-Adjust the heat sealing temperature and time parameters of the device and ｓｅｌｅｃｔ the best value according to the material characteristics.
-Clean the heat sealing device regularly to ensure its surface is smooth and clean.
-Use high quality packaging materials suitable for the equipment.
Problem performance:
1. Touching the ink when it is not completely dry causes damage to the pattern.
2. Drying too fast, resulting in poor ink flow in the screen printing process.
Cause analysis:
-The drying system temperature setting is unreasonable.
-The humidity of the production environment is too high or too low, affecting the performance of the ink.
-Ink and drying equipment is not enough to match.
Solution:
1. Adjust the temperature and wind speed of the drying system according to the characteristics of the ink to avoid too high or too low.
2. Install humidity control equipment in the production workshop to keep the environment stable.
3. Use high-quality ink that matches the equipment to ensure the drying effect.
Problem performance:
1. Printing pattern is blurred or unclear.
2. Too much ink penetration, resulting in blurred edges of the pattern.
3. Screen leakage or part of the pattern is missing.
Cause analysis:
-Insufficient screen tension or poor screen quality.
-Ink viscosity does not meet the requirements, too thin or too thick.
-Insufficient surface treatment of the pipette, insufficient adhesion.
Solution:
1. Regularly check the screen tension and ｒｅｐｌａｃｅ the screen with a high quality screen if necessary.
2. Adjust the ink viscosity according to production needs to ensure that its fluidity and adhesion is moderate.
3. Clean the surface of the pipette to ensure that it is free of dust and oil.
During long-distance transportation, goods are easily damaged or lost after many transshipments. Especially for high-value or fragile goods, this kind of problem is more prominent.
Solution:
-Packaging needs to meet international transportation requirements, especially fragile goods should use shockproof materials.
-ｓｅｌｅｃｔ additional insurance services to ensure compensation in case of loss or damage.
-Check the appearance of the package upon receipt, take photos and contact the logistics company if you find any problems.
International logistics costs are high, especially when transporting over long distances or when special commodities are involved (e.g. dangerous or fragile goods). In addition, different logistics companies charge different rates, which can easily confuse consumers.
Solution:
-Compare the prices and services of multiple logistics companies and choose the most cost-effective option.
-Understand the advantages and disadvantages of different modes of transportation (sea, air, land), according to the time and budget to choose the right program.
-If the shipping volume is large, you can negotiate with the logistics company to get bulk discounts.
Customs clearance is an important part of international logistics and express delivery, and many parcels are stuck in customs due to inconsistent declarations or incomplete materials. In addition, different countries have different tariff policies, which may lead to additional costs.
Solution:
-Make sure the declaration information is accurate, including commodity name, value and usage.
-Familiarize yourself with the tariff policy of the destination country and estimate the related costs in advance.
-Seek the help of a professional customs broker to ensure smooth customs clearance.
Cross-border transportation involves many links, including domestic transportation, international transportation, customs clearance and final delivery. Due to the complexity of the links, logistics timeliness is often affected by uncontrollable factors, such as weather conditions, flight delays or policy adjustments in the destination country. These issues may lead to prolonged express timeframe and affect the consumer experience.
Solution:
-Use well-known logistics companies with global networks, such as DHL, FedEx or UPS.
-Know the holidays and customs working hours of the destination country in advance.
-Choose a service with real-time tracking function, so that you can easily keep track of the logistics dynamics.
