The 50mm Nissei barrel stands out as a reliable, versatile choice for many Nissei injection molding machines. With a total length of 68 inches, this barrel fits a range of models and offers excellent durability and precision. Whether you are upgrading your equipment or replacing worn parts, understanding the specifications and compatibility of the 50mm Nissei barrel helps you make the best decision for your production needs.
Compatible Nissei Machine Series
The 50mm barrel is a standard size used across several Nissei plastic injection molding machine series. Knowing which machines support this barrel size ensures you order the correct part for your equipment.
FN Series
The 50mm barrel is standard for models such as FN2000-25A, FN3000-25A, FN3000-36A, and FN4000-36A. It also serves as the primary barrel size for FN180-50A and FN220-50A models. These machines are widely used in various industries, making the 50mm barrel a common replacement and upgrade option.
FNX and FNXIII Series
Hybrid models like FNX180-25A, FNX180III-25A, FNX180-36A, FNX180III-36A, FNX220-50A, and FNX220III-50A all use the 50mm barrel. These series combine electric and hydraulic features, requiring barrels that meet precise specifications for optimal performance.
Other Series
The 50mm diameter is also a standard bore size for parts replacement in the NEX (all-electric) series, FS series, and older PS series machines. This broad compatibility makes the 50mm barrel a versatile choice for many Nissei machine owners.
Technical Specifications of the 50mm Barrel
Understanding the technical details of the 50mm Nissei barrel helps you evaluate its suitability for your molding process.
Total Length
The barrel length is 68 inches (approximately 1727 mm), which includes the functional screw length and mounting sections. This length supports a range of length-to-diameter (L/D) ratios, typically between 20 and 30.
Screw Tip Assembly
The standard screw tip assembly for the 50mm barrel has an overall length of 7.28 inches and features a TR28 x 3.0mm left-hand thread. This design ensures secure attachment and smooth material flow during injection.
L/D Ratios
The L/D ratio affects the melting and mixing efficiency of the plastic material. For a 50mm barrel, an L/D ratio of 30 results in a functional length of about 59 inches (1500 mm), with the remaining length allocated to mounting and discharge areas. Different applications may require varying L/D ratios, but this range covers most standard molding needs.
Materials
Nissei barrels and screws are commonly made from high-quality materials such as:
- CPM 9V: Known for high wear resistance, ideal for abrasive materials.
- D2 Tool Steel: General-purpose with lower torque strength, suitable for less demanding applications.
- H13 Tool Steel: Nitrided for enhanced wear resistance, balancing durability and toughness.
These materials ensure the barrel withstands the high pressures and temperatures involved in injection molding.
