(2025年08月15日)Technical Report: Extrusion Blow Molding Process and Applications
Process Fundamentals
Extrusion blow molding (EBM) is a manufacturing process that transforms thermoplastic materials into hollow products through three primary stages:
Material melting and parison formation
Mold clamping and air inflation
Cooling and ejection
The technology offers distinct advantages in production efficiency and material utilization, making it indispensable for various industries.
Key Process Characteristics
