(2025年08月09日)Comprehensive Guide to Extrusion Blow Molding Technology
1. Introduction to Extrusion Blow Molding (EBM)
Extrusion blow molding is a fundamental manufacturing process essential for producing durable, lightweight, and cost-effective hollow plastic products. This technology serves as a backbone for industries such as packaging, automotive, medical, and industrial manufacturing, offering unparalleled efficiency and versatility.
2. Core Process Overview
The EBM process consists of three primary stages:
Material Extrusion: Plastic resin is melted and formed into a hollow tube (parison).
Mold Clamping: The parison is captured between two mold halves.
Blowing & Cooling: Compressed air inflates the parison against the mold walls, followed by cooling to solidify the shape.
3. Key Technological Advantages
High Production Efficiency: Optimized for mass production with rapid cycle times.
Material Utilization: Minimizes waste through precise control.
Design Flexibility: Supports complex geometries and varying container sizes.
Consistent Quality: Ensures uniform wall thickness (±0.1mm precision).
Material Compatibility: Works with diverse plastics, including HDPE, PP, PET, and engineered resins.
