1. Fundamental Principles of Extrusion Blow Molding
Extrusion blow molding (EBM) stands as a foundational manufacturing process for creating durable hollow plastic products. This versatile technology combines thermoplastic extrusion with precision air-blowing techniques to produce containers with exceptional strength-to-weight ratios.
Key Process Stages:
Material Preparation: Plastic pellets are melted into a homogeneous parison
Parison Formation: The molten plastic forms a continuous tube
Mold Closure: Precision molds capture the parison
Blowing Phase: Compressed air expands the parison against mold walls
Cooling & Ejection: Final product solidifies before removal
