Injection molding machines demand precision components to maintain performance and durability. The 72mm Nissei tip assembly stands out as a critical part designed for high-capacity injection units, especially in large-scale manufacturing. With an overall length of 9.24 inches and a 20-degree tip angle, this assembly fits specific Nissei FN series machines and other large hybrid or vertical models. Understanding its features and applications helps manufacturers optimize their injection molding processes.
What Makes the 72mm Nissei Tip Assembly Essential
The 72mm tip assembly is designed for machines with screw diameters ranging from 56mm to 71mm or larger. It is commonly used in:
Nissei FN220-71A and FN280-71A models
Other FN series machines in the 1000-4000 ton range
Large hybrid and vertical series such as FV, TWX, and TNX
These machines require heavy-duty front-end components to handle large shot sizes and high wear conditions. The tip assembly plays a vital role in ensuring smooth material flow and consistent injection quality.
Key Features of the 72mm Nissei Tip Assembly
Material Quality
The tip assemblies are typically made from high-wear materials like CPM 9V steel or general-purpose H13 steel with nitriding treatment. These materials provide:
High resistance to abrasion and wear
Enhanced durability under high pressure and temperature
Longer service life, reducing downtime and maintenance costs
Design and Construction
The assembly often comes in 3-piece or 4-piece free-flow designs. This modular approach allows:
Easier maintenance and replacement of individual parts
Improved flow of molten material, reducing shear and degradation
Compatibility with various screw designs and machine models
Application Suitability
These tip assemblies are ideal for large-shot molding applications, including those using glass-filled or other abrasive materials. Their robust construction supports:
High-volume production runs
Consistent part quality despite challenging materials
Reduced risk of tip wear affecting cycle times or product integrity
How the 72mm Tip Assembly Fits Into Nissei Machines
Nissei’s FN series machines are known for their large capacity and precision. The 72mm tip assembly matches the screw diameter and injection unit size, ensuring:
Proper sealing and pressure retention during injection
Efficient material transfer from screw to mold
Compatibility with machine-specific mounting and alignment requirements
For example, the FN220-71A model uses this assembly to handle large shot volumes while maintaining tight tolerances. Similarly, the FN280-71A benefits from the tip’s wear resistance during extended production cycles.
Benefits of Using the Correct Tip Assembly
Choosing the right tip assembly impacts production efficiency and product quality. Benefits include:
Reduced downtime due to longer-lasting components
Lower maintenance costs by avoiding frequent replacements
Improved molding consistency with stable material flow
Ability to process abrasive or glass-filled materials without premature wear
