A blow molding machine manufacturer specializing in the development and production of PET materials blows plastic containers of various PET materials

Everyone may be very familiar with bottle blowing machines. The most important thing is the machine equipment used to blow bottles. The bottle blowing machine can blow plastic particles or softened liquids into people through certain technological means. Compared with other raw materials, the plastic hollow container is not only light in weight and low in price, but also very safe. It can be seen everywhere in our lives, especially the various beverages used at home. Bottles, etc. are all made of plastics as raw materials, which brings more and more convenience to people. However, what should people do if they use the bottle blowing machine? 1. Before using the bottle blowing machine, it is necessary to seriously check whether the moving parts are stable, and it is also necessary to seriously check whether the screws are softened. If so, they should be tightened immediately to ensure safety and safety during use. stability. 2. In places where the impact force is very weak, check whether the belt drive part is stable and whether there is serious wear and tear. It needs to be replaced and treated, and it is also necessary to add lubricating oil to each part to ensure the service life of the mechanical equipment. More years. Maintaining the bottle blowing machine in a certain order can not only ensure the stable production of the product, but also extend the use time of the machine and equipment. Therefore, in addition to the maintenance of the bottle blowing machine, the following maintenance rules must be accurately implemented to improve product quality and productivity. 1. If the blow molding machine fails, repair it as soon as possible. If you can take advantage of the power outage or the replacement of the product when the operation is done, it will help reduce the downtime and will never delay the machine production. 2. The parts that affect the blowing quality of the bottle blowing machine need to be replaced or repaired every six months. If there are any parts that affect the quality of the bottle blowing, the service time can be shorter and the maintenance cost can be reduced. 3. If you want to repair the bottle blowing machine in a small area, it is best to repair it together at the time of the glass melting furnace to avoid the downtime of the bottle blowing machine during the production process. How many problems do blow molding machines often encounter in the process of blow molding? 1. Thin on the top and thin on the bottom: postpone the pre-blowing time, or reduce the pre-blowing pressure to reduce the air flow. 2. Thicker underneath and thinner on top: the opposite of the above. 3. There are wrinkles under the bottleneck: the pre-blowing is too late or the pre-blowing pressure is very high, or the billet is cold here instead. 4. White bottom: the preform is very cold; too stretched; the pre-blowing is too late or the pre-blowing pressure is very low. 5. There is a magnifying glass at the bottom of the bottle: there is too much material at the bottom of the bottle; the pre-blowing is too late and the pre-blowing pressure is very high. 6. There are wrinkles in the bottom of the bottle: the bottom temperature is very low (the heat at the gate is good); the pre-blowing pressure is very high and the flow rate is very large. 7. The whole bottle is turbid (not uniform): cold is enough. 8. Partial whiteness: Excessive stretching, the temperature here is so high, or the pre-blowing is too late, or the stretch rod is hit. The following are the three remaining undesirable phenomena in the bottle blowing machine: (1) The bottle wall of the bottle blowing machine is very thick as a whole. The main reason is that the preform stretching temperature is very low and the preform stretching ratio is very small. (2) The bottom of the bottle of the bottle blowing machine is thin and the top is thin. The reason is that the drawing speed is very fast, the primary blow molding pressure is very low, and the secondary blow molding time is by no means appropriate. The temperature of the upper part of the preform is high and the temperature of the upper part is low during stretch blow molding. (3) The bottom of the bottle of the bottle blowing machine is thin and the top is thin. This is caused by the very slow stretching speed, very high primary blow molding pressure, improper control of the second blow molding time, and improper temperature control on both sides of the stretch blow molding. How to select a bottle blowing machine with a higher price than a low price. For the bottle blowing machine, many people who are new to the plastic bottle industry need to understand and learn a lot of knowledge before purchasing, and they need to buy according to their own needs. The more expensive the bottle blowing machine is, the better it is, but it may not be suitable for you. Since many factors are involved in the final production process of the bottle blowing machine, only finding the right one can play the smallest use and produce the best benefits. For some large-scale beverage, mineral water or cosmetics manufacturers, due to the very small amount of packaging used, they are often integrated with the product filling. This type of blow molding machine should be fully automatic, high-speed, stable and reliable in quality. The bottle blowing machine alone will never affect other links in the final production process and affect the overall production efficiency. For some small and medium-sized manufacturers, a semi-automatic, two-step blow molding machine can also be considered. On the other hand, it can reduce the cost of the first purchase of a blow molding machine. At the same time, this type of blow molding machine is also above the production capacity. Quite a bit higher, more and more in line with the needs of manufacturers. Since the plastic bottles produced by the blow molding machine are hollow products, if they are stacked in large quantities, they will put very little pressure on the storage. For some individuals or family workshops, you can consider using second-hand blow molding machines at the beginning. The price of this type of blow molding machine is quite high. If you understand the parameters of various aspects and buy again, there are still many machines with higher prices than low prices. Selected.
