1. After the product comes out of the annealing line, the quality inspection personnel must perform a full inspection of all products. The focus is:
(1) Bubbles in bottles: Bubbles are the easiest problems in the production of glass bottles. Most QC personnel in inspections cannot accurately determine the size. For example, the bubbles above 1 mm on the sealing surface of the bottle mouth are not allowed to have. Bottle: ∮ 1mm below the bubble - less than 6 square centimeters less than 1; 1mm <∮ <6mm bubble is not more than 3, and the spacing is above 20mm; the surface is not allowed to break the bubble, etc. Difficult to grasp, only with a film of different shapes compared.
(2) Neck neck: The main operation is to get started. In the operation, the die and die are misaligned or one side of the die is not completely placed on the die, requiring the operation to be corrected. Even if it does not affect the fit with the lid, it also affects the appearance of the entire glass bottle.
(3) Inclined bottom: uneven feeding at the bottom, half thick, or even more than half, affecting product quality and reducing the product grade.
(4) The thickness of the stitching thread: The stitching thread exceeds the surface of 0.5 mm, and even the feeling of hand scraping is not allowed, and the special bottle mouth sealing surface is not allowed. The main reason is that the mold is not in place or worn, and it needs to be repaired, polished, polished and combined.
(5) Material color: In general, the color of the material will not be changed. In addition to the changes in the ingredients of the raw materials used, generally it will not change. If there is a phenomenon of turning green or returning blue, the formula may be properly adjusted for color removal.
(6) The inner and outer diameter of the mouth and the presence of a notch in the mouth: The inner and outer diameters of the mouth and the doorway are most likely to cause problems. Outer Diameter: Because the die is easy to get oily during use, the anti-skid teeth become smaller, the lid of the bottle is left and right slippery, and it cannot be tight; the inside of the glass bottle is bright and the lid cannot be tight after inserting the inner plug, which can lead to tightness. The main reason for skipping wine is that the material is too soft; or the operation starts after the material enters the first mold and the core pulling speed is too fast, and the material is not completely formed; or it may be that the core is too short, and the core may be appropriately lengthened. Can be solved.
(7) Blocking material (bottle deflection): The main reason is that the material is too red (temperature is too high), not completely cooled, caused by the formation of particles after molding, and it may be that the molded product is not placed on the bottom. Caused by the Central Government.
(8) Thin shoulders: Generally, the square bottle is easy to appear. This is because the mold design is mainly based on the operation of the soft material and timing of the operation (material color) to prevent the blind corners from stumbling, resulting in a thin arm, which makes the test difficult to grasp. On the way, there is a great deal of damage during transport or bottling and sales. In the test, you can use the adhesive to gently tap the armrest area and find that the problem is immediately reflected in order to correct it.
(9) The glass bottle is not bright: the bottle is numb, fog, and the transparency is not good. Mainly after the mold in the molding release agent, the inner surface of a layer of carbide, which can be polished to solve.
(10) Hemp material: There is more hemp material on the bottle body, mainly the pool furnace temperature is too low, the material is not fully cooked, or the feeder speed is too fast, the machine speed can be reduced, the discharge amount can be reduced, and the temperature of the molten material in the pool can be guaranteed. Measures to solve.
Incoming sampling:
The quality management personnel sample the finished product batches that have been packaged and are to be stored in the warehouse according to the AQL count sampling plan. Samples shall be sampled in all directions (upper, middle, and lower parts) as much as possible. The inspection shall be conducted strictly in accordance with standards or customer requirements. Qualified batches shall be put into warehouses immediately, stacked neatly and clearly marked; unqualified batches shall be immediately marked, segregated, and reworked and disposed until they pass the spot inspection.
Family health management is gradually emerging, and hyperbaric oxygen chambers are also gradually entering the public's field of vision. Hyperbaric oxygen chambers can provide convenient home care for family members and improve their quality of life.
DOING hard shell Hyperbaric Oxygen Chamber provides an oxygen rich environment, which can increase the oxygen partial pressure and oxygen content in the human blood, promote cell metabolism, and alleviate symptoms of hypoxia. Meanwhile, sufficient oxygen helps promote tissue regeneration, thereby accelerating wound healing.
The oxygen production principle of DOING high-pressure oxygen chamber is molecular sieve oxygen production. Molecular sieve first compresses and filters the air, and then adsorbs nitrogen from the air under high temperature and pressure, leaving a high concentration of oxygen.
DOING hyperbaric oxygen cabin is equipped with two transparent observation windows, which are well lit and can provide a good visual experience for the personnel inside the cabin. There will be no shortage of light, and the cabin will not lack a sense of security for the personnel inside.
DOING high-pressure oxygen chamber is equipped with automatic and manual pressure relief valves. When the automatic pressure relief valve is not working or there is an emergency situation inside the chamber, the manual pressure relief valve can be used to manually reduce pressure and ensure safety.
