The 25MM Arburg screw stands out as a key component for several Arburg machine models, offering consistent performance and durability. Whether you operate an Arburg 320S-500-150 or compatible models like the Allrounder 270S, 221K, or 370C series, understanding the specifications and benefits of this screw can help you maintain optimal production quality.

Key Specifications of the 25MM Arburg Screw
The 25MM Arburg screw measures a total length of 28.75 inches. It is divided into four main sections, each designed to perform a specific function during the injection molding process:
Drive section: 6.65 inches
Feed section: 11.04 inches
Transition section: 5.53 inches
Meter section: 5.53 inches
Each section contributes to the efficient melting, mixing, and injection of plastic material. The drive section powers the screw rotation, the feed section moves raw material forward, the transition section compresses and melts the plastic, and the meter section ensures consistent material flow into the mold.
Compatible Arburg Models
This 25MM screw is specifically designed for the Arburg 320S-500-150 model, a 55-ton injection molding machine known for its precision and versatility. Additionally, it fits several other Arburg machines that use 25mm screws, including:
Arburg Allrounder 270S series
Arburg 221K series
Arburg 370C series
Knowing which models are compatible helps operators source the right screw replacement without risking machine downtime or production issues.
Why Choose the 25MM Arburg Screw?
Choosing the right screw for your injection molding machine affects product quality, cycle times, and maintenance costs. The 25MM Arburg screw offers several advantages:
Consistent melt quality: The carefully designed sections ensure uniform melting and mixing of plastic pellets.
Durability: Made from high-quality materials, this screw withstands wear and tear from abrasive materials.
Improved cycle times: Efficient material flow reduces injection time, increasing productivity.
Easy replacement: Standardized dimensions make it straightforward to swap out old or damaged screws.
Operators who maintain their machines with the correct screw size and type often see fewer defects and longer machine life.
How to Identify When You Need a New Screw
Injection molding screws wear down over time due to friction, heat, and material abrasiveness. Signs that your 25MM Arburg screw may need replacement include:
Increased cycle times or inconsistent injection pressure
Visible wear or scoring on the screw surface
Poor melt quality or inconsistent part dimensions
Frequent machine downtime for maintenance
Regular inspection and timely replacement prevent costly production delays and maintain product quality.
