Blow molding is a process specifically designed for mass production of hollow plastic containers. This issue will introduce Extrusion Blow Molding (EBM) in the blow molding process.
Process cost: Processing cost is moderate, and the cost per unit is low. Typical products: Chemical product packaging, consumer product packaging, and pharmaceutical packaging. Suitable production volume: Only suitable for large-scale production. Quality: High quality, with completely uniform wall thickness and suitable surface treatment options such as smooth, matte, or textured finishes. Speed: Fast, with an average cycle time of 1-2 minutes.
Blow molding can be divided into three categories:
- Extrusion Blow Molding (EBM): The lowest cost among the three categories, suitable for producing hollow plastic containers (PP, PE, PVC, PET) ranging from 3 ml to 220 liters.
- Injection Blow Molding (IBM): To be continued in the next issue.
- Stretch Blow Molding (ISBM): To be continued in the following issue.
