www.completeplastics.com, sales@completeplastics.com. The 50mm Nissei barrel with a total length of approximately 59.29 inches (about 1506mm) is a key component for many Nissei injection molding machines. If you operate or maintain Nissei equipment, understanding the specifications and compatibility of this barrel can help you keep your production running smoothly. This post explains where this barrel fits, which machines use it, and why it matters for your injection molding operations.
What is the 50mm Nissei Barrel?
The 50mm Nissei barrel refers to the diameter of the screw and barrel assembly used in certain Nissei injection molding machines. The screw diameter of 50mm is a common size for machines with a clamping force ranging from 180 to 250 tons. The barrel length of 59.29 inches (1506mm) is designed to fit specific Nissei models, ensuring optimal melting and injection of plastic materials.
This barrel is a critical part of the injection unit, responsible for melting, mixing, and injecting plastic into molds. Its size and length affect the machine’s performance, including cycle times, melt quality, and shot size.
Machines Compatible with the 50mm Nissei Barrel
Several Nissei injection molding machine series use the 50mm barrel with a 59.29-inch length. These include:
Nissei FN2000 Series
Models in this series, especially those with 180-250 ton clamp force, commonly use the 50mm barrel. The FN2000 series is known for reliable performance in medium to large part production.
Nissei FN1000 Series
The FN1000 series also features machines equipped with the 50mm diameter barrel, suitable for a range of molding tasks requiring precise control.
Nissei PNX Series
The PNX120 and related models in this series use the 50mm barrel, offering versatility for various molding applications.
Nissei FNX Series
The FNX series machines utilize the 50mm barrel for high-speed and precise molding operations, often in electric or hybrid configurations.
Nissei Electric 50E Injection Unit
This all-electric injection unit uses the 50mm barrel with the 59.29-inch length, providing energy-efficient and precise molding.
Nissei 50A Hybrid Injection Unit
The hybrid 50A unit also supports this barrel size, combining electric and hydraulic technologies for flexible production.
Why the 59.29-Inch Length Matters
The length of the barrel affects the melting and plasticizing process. A 59.29-inch barrel provides enough length for thorough melting and mixing of plastic pellets before injection. This length is standard for the 50mm barrels used in the 180-250 ton clamp range machines.
Using the correct barrel length ensures:
Consistent melt quality
Proper shot size and injection pressure
Reduced risk of material degradation
Improved cycle times
Choosing a barrel that matches your machine’s specifications avoids downtime and maintains product quality.
Benefits of Using the 50mm Nissei Barrel
Selecting the right barrel size and length for your Nissei machine offers several advantages:
