Most of the glass bottle manufacturers in the product factory, will receive customers a variety of product quality problems, causing customer complaints, causing losses to both sides.
Reasons to blame: mainly in the production process, caused by improper quality control.Now on the production process quality control focus for some shallow discussion.
1.Test the mold
For the professional production of glass bottle manufacturers are mostly based on the mold provided by customers, or according to the drawings of the new bottle mold production,To the key dimensions of the die that will affect the forming,Communicate and negotiate with customers at the time of mold opening, and reach consensus on key size modification opinions.
All the molds in the factory must be the first die of the mold to form a complete set,Perform inspection according to drawing or customer requirement.
2. First item inspection
When the bottle first came out of the annealing line,The quality inspection monitor shall limit each molded product to 2-3 pieces,Check all aspects according to the drawing,The point is in addition to the above,Another volume measurement is required,Material weight measurement,The inside and outside diameters of the opening,Fill the bottle with water if necessary,Use the cover provided by the customer for physical assembly,Check whether the cover is in place,Whether is leaking,The acid and alkali resistance of internal pressure and internal stress were tested.
3. Process inspection
Without changing the mold,Every two hours,Two of each mold were drawn for capacity material weight test,In addition, the inside and outside diameters of the orifice should be tested,Prevent the mouth die from being easily smeared with oil in use,Lead to the lid is not strict and appear leakage of wine phenomenon.
It may be due to the mold in the manufacturing process,Put on a new mold,Therefore, after changing the mold, the molding workshop must inform the quality inspection workshop immediately,The quality control workshop must conduct the first piece inspection and process inspection for the bottles made with the new mold,Put an end to the quality problems caused by the missing inspection due to the change of mold.
