Hollow Extrusion Mold Manufacturers for Blow Molding Machines – A Complete Guide
Introduction
Hollow extrusion molds are critical components in blow molding machines, used to produce plastic bottles, containers, and industrial hollow products. Choosing the right hollow extrusion mold manufacturer ensures high-quality production, efficiency, and durability.
This guide covers top manufacturers, key selection criteria, and industry trends for blow molding machine molds.
1. What Are Hollow Extrusion Molds?
Hollow extrusion molds are specialized blow molding dies that shape molten plastic into hollow products. They are used in:
Extrusion Blow Molding (EBM) – For large containers (e.g., drums, fuel tanks).
Injection Blow Molding (IBM) – For precision bottles (e.g., medical, cosmetic).
Stretch Blow Molding (SBM) – For PET bottles (e.g., beverage, detergent).
Key Features:
✔ High wear resistance (chrome-plated steel, aluminum alloys)
✔ Precision cooling channels for faster cycle times
✔ Customizable cavity designs
