Types of Injection Barrels
Different industries require different types of injection molding barrels depending on material and application.
1. Standard Injection Barrel
The standard injection barrel is widely used in plastic molding machines. It is suitable for general plastic materials and provides reliable performance for daily production.
2. Bimetallic Injection Barrel
A bimetallic injection barrel offers superior wear resistance and corrosion protection. It is ideal for processing abrasive materials such as fiberglass-filled plastics or recycled materials.
3. Nitrided Injection Barrel
The nitrided injection barrel undergoes a special heat treatment process that increases surface hardness and durability, making it perfect for long-term industrial use.
