Bottom accumulation in blow molding machines can be attributed to a variety of factors, such as inadequate temperature, processing methods, and insufficient blow molding time. While the specific circumstances may vary, let's explore practical solutions to address bottom accumulation.
Insufficient heating temperature at the bottle bottom is a major contributor to accumulation. When the bottle bottom fails to reach the required heating temperature during blow molding, it hampers the air blowing process. Adjusting the temperature of the bottom heating lamp offers a viable solution.
Another crucial factor is inadequate pre-blowing time. When the pre-blowing time is too short, it leads to uneven air distribution at the bottle bottom, resulting in accumulation. Extending the pre-blowing time effectively resolves this issue.
Although relatively uncommon, a shortened stretching rod can also cause problems. While blow molding machines undergo quality tests before leaving the factory, there may be instances where smaller manufacturers neglect responsible measures. In such cases, replacing the stretching rod is necessary.
Insufficient high-pressure blowing time is yet another factor. When the high-pressure blowing time is set too short, the bottle bottom may not form properly, leading to deformation or accumulation. Prolonging the high-pressure blowing time provides an effective solution.
Misalignment or deviation between the bottle bottom mold and the mating mold can also contribute to deformation or accumulation. By adjusting the position of the mold bottom and the mating mold, manufacturers can ensure proper alignment without any deviation.
In general, resolving bottom accumulation in blow molding machines requires diligent attention to fundamental processes. Implementing these practical solutions empowers manufacturers to minimize or eradicate the issue, thereby optimizing their production processes.
