Bottle blowing machine product detection abnormalities and solutions
Bottle height, bottle wall thickness, body diameter size, injection point capacity, volume shrinkage rate, and body diameter shrinkage rate, when exceeding the process control specifications, double sampling and measurement and follow up.
Finished product of blowing section
1. Bottle height, bottle wall thickness, body diameter size, injection point capacity, volume shrinkage rate, and body diameter shrinkage rate, when exceeding the process control specifications, double sampling and measurement and follow up.
2. Heat resistance: After filling with hot water, the center temperature of the bottle is 91±1℃. When the bottle body is obviously deformed, double the sampling and measurement. If the excess is true, an isolation order will be issued to notify the production improvement and follow-up.
3. When the load, drop strength, and heat-resistant vacuum index fail to meet the specification requirements, double the sampling and measurement. If the excess is true, an isolation order will be issued to notify the production improvement and follow-up.
4. When there is a slight abnormality in the appearance of the product, contact the production line to take preventive measures to avoid the occurrence of substandard products. When the appearance is abnormal, an isolation order will be issued to notify the production improvement, and the semi-finished products will be isolated for inspection during the relevant period.
Tracing and isolation of non-conforming products
Once unqualified products are found in production, the on-site adjustment and improvement should be notified immediately, and the defective products should be tracked and isolated. Operation method: Sampling inspection of the previous pallet produced during this period. If defective products are found, continue to sample the adjacent and previous pallet board until no defective products are found.
