I. Die Inspection
1. Most of the manufacturers specializing in glass wine bottles are based on the mould provided by customers or the newly opened mould according to drawings and sample bottles. For the key dimensions of the mould which will affect the forming process, they must communicate and negotiate with customers when opening the mould and reach consensus on the modification of the key dimensions.All moulds must be matched with the die, the initial die and the finished die when they enter the factory, and checked according to the drawings or customer's requirements.
II. First Inspection
1. In the first 10-30 products produced before the die is put on the machine and annealing line, 2-3 products are selected from each die for dimension inspection. The key points of inspection are mouth height, inner and outer diameter, correct and clear bottom engraving and correct bottle body pattern.
2. When the bottle comes out of the annealing line, the head of the quality inspection team will limit the product produced by each moulding to 2-3, and inspect it in all aspects according to the drawings. The key point is that besides the above, capacity measurement, material weight measurement, inner and outer diameters of the calibre are also needed. If necessary, the bottle will be filled with water, and the cap supplied by the customer will be used for physical assembly to check whether it is or not. Can cover in place, whether leakage. The internal pressure, internal stress, acid and alkali resistance were tested.
