I. Mold inspection:

1. For glass bottle manufacturers, most of them produce according to the molds provided by customers, or according to the newly opened molds of drawings and sample bottles. For the key dimensions of molds that will affect the forming, it is necessary to communicate and negotiate with customers immediately in the opening of molds, and reach a consensus on the modification opinions of key dimensions

2. All molds shall be equipped with the mouth mold, initial mold and finished mold when entering the factory, and shall be inspected according to the drawings or customer requirements.

Ii. Inspection of Parts:

1. It is the first 10-30 products produced before the retreat and retreat of the die machine. Each die is pumped 2-3 products for size and specification inspection. Inside and outside diameter of 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 quenching line, the quality inspection monitor will limit the products out of each mold to 2-3 only, and test in accordance with the drawings in all aspects. In addition to the above, the capacity measurement, material weight measurement, the inner and outer diameter of the mouth, when necessary, the Chiang 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.

Iii. Process inspection:

1. Under the condition that the mold is not changed, every 2 hours, 2 pieces of each mold are extracted for capacity and material weight detection. In addition, the inner and outer diameters of the orifice should be detected.

2. New molds may be replaced during the process because of the mold. Therefore, the molding workshop shall immediately notify the quality inspection workshop after the mold change.

Iv. Full Inspection:

1. After the products come out of the annealing line, the quality inspection personnel shall carry out a full appearance inspection on all products, which is:

(1) Bubble of the bottle: Bubble is a common problem in the production of glass bottles, and most quality inspection personnel cannot grasp the size correctly. For example, bubble of more than 1mm on the sealing surface of the bottle mouth is not allowed; Bottle body: Bubbles below 1mm - no more than 6 bubbles within the square centimeter; There are no more than 3 bubbles of 1mm

(2) Crooked neck: It is mainly caused by the dislocation between the mouth die and the forming die or the side of the mouth die is not completely placed on the forming die during the operation of the operator. It can be solved by correcting the operation of the operator. Even if it does not affect the fit with the lid, it also affects the appearance of the whole bottle.

(3) Oblique bottom: uneven material at the bottom, half of the thickness, even more than half, affect the quality of the product, lower the grade of the bottom product.

(4) The thickness of the sealing line: the sealing line is more than 0.5mm on the surface, and even the feeling of scraping is not allowed. The special sealing surface of the bottle mouth is not allowed. The main reason is that the mold is not closed in place or wear, need to be repaired, polished, polished and combined.

(5) material color: Generally speaking, the material color will not change greatly except for the changes of the ingredients of the raw materials. If the phenomenon of turning blue or turning blue occurs, the formula can be adjusted appropriately for color removal.

(6) The inside and outside diameter of the mouth and the appearance of the concave mouth: the inside and outside diameter of the mouth and the door are prone to problems. Outer diameter: Because the mouth die is easy to be stained with oil in use, resulting in small anti-slip teeth, the lid on the left and right slip, can not be tight; There is a notch in the mouth of the bottle, and the inner plug of the lid can not be tightly inserted, which will lead to wine leakage. The main reason is that the material is too soft; Or the core-pulling speed is too fast after the material enters the initial mold, and the material is not fully formed; It is also possible that the core is too short, and can be properly lengthened a little bit.

(7) seat material (bottle skew) : the main reason is that the material is too red (temperature is too), not completely cooled, caused by particles after molding, may also be formed out of the product is not in the center of the bottom caused by.

(8) Thin shoulder: Generally, square bottles are easy to appear. Because the mold design is so, it mainly relies on the soft material action and the timing (material color) of the operator to prevent the dead Angle from running, which leads to thin arms, so that the inspection is difficult to grasp, and the damage is large during transportation or wine filling and sales, resulting in losses. During the inspection, you can use a rubber hammer to gently tap the arm, and immediately report any problem, so as to correct it.

(9) The bottle is not bright: the bottle is spotless, foggy, and the transparency is not good. Mainly in the mold in the molding of release agent, there is a layer of carbide on the inner surface, it can be polished.

(10) hemp material: hemp material on the bottle body is much, mainly because the furnace temperature in the pool is too low, the material is not fully cooked, or the feed machine is too fast, which can reduce the machine speed, reduce the amount of material, ensure the solution temperature in the pool and other measures.

V. Sampling inspection of warehousing:

The quality management personnel shall carry out sampling according to the AQL counting sampling plan for the finished product batches that have been packed and are to be stored. Sampling shall be carried out in an all-round way (upper, middle and lower parts) as far as possible, and inspection shall be conducted strictly according to the standards or customer requirements. The qualified batches shall be immediately stored, stacked neatly and marked clearly. The unqualified lot shall be immediately marked, isolated and required to be reworked for disposal until it is qualified by random inspection.

Vi. Inspection of roasted flower processing bottles:

1, color rered: the main reason is the temperature, the speed of the net belt is too slow, and the color removal agent caused by the reduction reaction.

2. Poor adhesion of flowered paper: in addition to the material of flowered paper itself, it is mainly caused by too low temperature. Because of different materials of flowered paper, the required temperature of baking flowers is not the same, therefore, it is necessary to adjust the baking flowers.

3, flower paper foam: there are many holes on the bottle flower paper baked out, the reason is that after pasting the flower paper, the bubble in the flower paper is not brushed off, or the surface of the flower paper is not dry, immediately caused by baking flowers. To have baked flowers but not qualified products can be scraped off with hydrochloric acid, re - decal baking.

4, different degrees of mixed packaging: because the bottle type is identical, the flower paper in addition to different degrees is completely the same, decal, baking, inspection, packaging, easy to mixed packaging of different degrees of bottles, resulting in customer complaints, quality accidents.
