The production cycle of a blow molding machine refers to the total time required from raw material input to final product output. Calculating the production cycle involves multiple stages, including raw material preparation, equipment startup and commissioning, normal production processes, and product inspection and packaging. To accurately calculate the production cycle, we need to consider the following factors:
1. Raw Material Preparation Time: This includes the time required to retrieve the necessary materials from the raw material warehouse, perform pretreatment (such as drying and mixing), and transport the materials to the blow molding machine.
2. Equipment Start-up and Commissioning Time: Before each production run, the blow molding machine needs to be started and commissioned to ensure normal operation and product quality. This time varies depending on the equipment model and complexity.

3. Normal Production Time: This refers to the time the blow molding machine operates in a stable state. This time can be obtained using the calculation methods for production quantity and capacity mentioned above.
4. Product Inspection and Packaging Time: After production is completed, the products need to undergo quality inspection and packaging. This time depends on factors such as product quality standards, packaging methods, and the degree of automation.
In summary, the production cycle of a blow molding machine can be calculated by adding up the time of each of the above-mentioned stages. It should be noted that due to various uncertainties in actual production (such as equipment failures and fluctuations in raw material quality), the calculated production cycle may only be a rough estimate.
