How to improve the performance of bottle blowing mold

At present, the production technology of bottle blowing mold has reached a high level, but there is still much room for improvement. Improving any performance of the blowing mold will greatly improve the production of plastic bottles. So, what aspects can improve the performance of the bottle blowing mold?
First of all, the production of bottle blowing mold is currently made of steel. We all know that the cost of steel is very high. If a manufacturer needs to make a new bottle blowing mold in order to blow a new bottle, it often needs to pay a high cost. If we can find a cheaper material for bottle blowing mold, it will greatly reduce the production cost of plastic bottles.
Secondly, the life of the bottle blowing mold requires that the bottle blowing mold be blown in a high temperature environment. Therefore, the production life cycle of many bottle blowing molds is not long. Extending the life cycle of bottle blowing molds is also an effective way to reduce costs.
Finally, the production efficiency of the bottle blowing mold, the first mock examination with multiple cavities can effectively improve the bottle blowing efficiency, but how to achieve more cavities in the first mock examination in the limited space of the bottle blowing machine is a very challenging problem.
The bottle blowing mold is a very important part of the plastic bottle blowing molding. The improvement of the performance of the bottle blowing mold in all aspects is of great significance to the entire plastic bottle industry.
