The speed of glass bottle manufacturers when changing products is the embodiment of the level of bottle making technology of bottle and glass enterprises. What we sometimes see is: the scene is in a hurry, molds and accessories are all over the floor, hot and cold glass bottles are flying around, this group of materials skips, and that group of jaw arms cannot be turned over; this group of clamp bottles cannot come out, That group of blowing heads is blocked; this group squeezes the bottles, and that group of molds cannot be closed. The work that should have been completed in one hour, the machine still cannot be stabilized in two hours, and sometimes the product will not be produced in half a shift, and when encountering slightly more difficult products, qualified products will not be produced in one or two shifts. The cumulative losses resulting from this are enormous. These phenomena indicate that the bottle-making technology is immature, and the bottle-making management needs to be improved. Over the years, we have been committed to the research of improving bottle making technology, especially in the active exploration and summary of how to quickly replace products.
