770-417-6983 / sales@completeplastics.com. Injection molding machines demand precision components to maintain high performance and consistent output. The 50mm Nissei free flow tip assembly stands out as a reliable part designed to meet these needs. With an overall length of 8.42 inches and a 20-degree tip angle, this 3-piece screw tip assembly fits a wide range of Nissei machines, ensuring smooth and efficient molding operations.

What Makes the 50mm Nissei Free Flow Tip Assembly Essential?
The 50mm Nissei free flow tip assembly is engineered for machines with 50mm screw diameters. It is compatible with many Nissei injection molding machine models, including FS, FE, ES, FN, FV, NS, FNX, FNXIII, NEX, NEXIII, PNXIII, TNXIII, and TH series. This broad compatibility makes it a versatile choice for manufacturers who rely on Nissei equipment.
Key Features
Three-piece design: The assembly consists of three parts, allowing for easy maintenance and replacement.
Free-flow check valve: This design supports precise and consistent injection, reducing defects and improving cycle times.
20-degree tip angle: Optimizes material flow and reduces back pressure during injection.
Overall length of 8.42 inches: Fits perfectly within the screw housing of compatible machines.
Compatibility with Nissei Machine Series
The 50mm assembly is widely used across popular Nissei series such as FN, FNX-III, and NEX, including advanced models like NEX-IV and NEX-V. These series are known for their high-performance molding capabilities, making the tip assembly a critical component for maintaining machine efficiency.
Horizontal and Vertical Machine Use
This tip assembly works well in both horizontal and vertical injection molding machines. For example, it fits models like the TH-EⅢ and TNX-RⅢ, which are designed for different molding orientations but require the same precision in screw tip performance.
Control System Compatibility
The assembly is compatible with Nissei’s NC Series control systems, including NC8300, NC9000, and NC9300. It also supports TACT control systems such as TACT, TACT III, TACT IV, and TACT5. This ensures that the tip assembly integrates seamlessly with the machine’s control electronics, helping operators maintain precise control over injection parameters.
Benefits of Using the 50mm Nissei Free Flow Tip Assembly
Improved Injection Speed and Consistency
The free-flow design of the check valve allows for faster injection speeds without sacrificing accuracy. This leads to shorter cycle times and higher throughput, which is essential for manufacturers aiming to increase productivity.
Reduced Wear and Maintenance
The three-piece construction simplifies replacement of worn parts, reducing downtime. Operators can replace individual components instead of the entire assembly, saving costs and minimizing machine stoppages.
Enhanced Material Flow
The 20-degree tip angle helps maintain smooth material flow through the screw, reducing the risk of material degradation and improving the quality of molded parts.
Practical Applications and Examples
Manufacturers using Nissei machines in automotive, consumer goods, and electronics industries benefit from this tip assembly. For example, a company producing small plastic housings for electronic devices reported a 15% reduction in cycle time after switching to the 50mm Nissei free flow tip assembly. The improved flow and injection speed allowed them to meet higher demand without compromising part quality.
