First, mold inspection:
1, for the production of glass bottle manufacturers are mostly in accordance with the mold provided by customers, or according to drawings, sample bottles newly opened mold production, will affect the mold key size, must be in the mold immediately communicate with customers, negotiations on the key size modification opinions to reach a consensus, the later product yield and molding effect has a vital impact. 2, all molds in the factory must be the mold of the mold, the initial mold, mold supporting, according to the drawings or customer requirements for inspection.
Two, inspection:
1, is in the mold after the machine before the fire, the production of the first 10-30 products, each mold draw 2-3 products for size specification inspection, inspection is the size of the mouth; The inside and outside diameter of the mouth; Whether the lettering on the base is correct and clear; Whether the bottle body pattern is correct.
2. When the bottle comes out from the anneal line, the quality inspection monitor will limit the products of each mold to 2-3 only, and test them in accordance with the drawings in all aspects. In addition to the above, it is necessary to make capacity measurement, material weight measurement, the inner and outer diameter of the mouth, if necessary, the Jiang bottle is filled with water, and the lid provided by the customer is used for physical assembly to test whether it can be covered in place and whether it leaks. And make internal pressure, internal stress, acid and alkali resistance test.
Third, process inspection:
1. When the mold is not changed, every 2 hours, each mold is pumped 2 for capacity and material weight detection, and the inner and outer diameter of the mouth need to be detected, because the mouth mold is easy to be stained with oil in use, resulting in loose lid leakage phenomenon.
2, the process may be due to mold reasons, replaced with a new mold, therefore, after the mold change molding workshop must immediately notify the quality inspection workshop, quality inspection workshop must be the newly changed mold out of the bottle part inspection and process inspection, to eliminate due to the change of mold, quality inspection is not known and missed to produce quality problems.
