770-417-6983 / sales@completeplastics.com. Injection molding machines demand precise and reliable components to maintain high-quality production. One critical part is the tip assembly, which directly affects material flow and molding accuracy. The 36mm Nissei free-flow tip assembly stands out as a dependable replacement for various Nissei machines, offering a smooth flow and consistent performance. This post explores the features, compatibility, and benefits of this specific tip assembly, helping you make an informed choice for your injection molding needs.

What Makes the 36mm Nissei Free Flow Tip Assembly Special
The 36mm free-flow tip assembly is designed for Nissei injection molding machines equipped with a 36mm diameter screw and barrel. This size corresponds to specific injection units such as the 18A and 36A models. The assembly features:
Overall length of 5.39 inches
Tip angle of 20 degrees
A 3-piece check valve design that ensures smooth material flow and prevents backflow
This design promotes efficient plasticizing and injection, reducing cycle times and improving part quality. The free-flow tip assembly is engineered to fit tightly and maintain consistent pressure, which is crucial for molding precision.
Compatible Nissei Machine Series and Models
The 36mm free-flow tip assembly fits a wide range of Nissei machines. Knowing your machine model helps ensure you select the right part. Compatible series and models include:
FN Series
Models such as FN1000-12A, FN1000-18A, FN2000-18A, FN140-36A, and FN180-36A
FNX Series (Hybrid)
Includes FNX140-36A, FNX180-36A, and the "III" generation models like FNX140III-36A and FNX180III-36A
Vertical Machines
The TWX300RIII36V, a newer large vertical hybrid model, also uses this 36mm unit
General Series Compatibility
Free-flow assemblies in this size are standard replacements for 36mm bore units across FS, FE, ES, FN, FV, NS, NEX, PNX, TNX, and TH series
This broad compatibility makes the 36mm free-flow tip assembly a versatile choice for many Nissei machine owners.
Confirming Fitment for Your Machine
Before purchasing, confirm your machine’s controller type, such as NC Series or TACT. Controller differences can affect technical specifications for front-end components like the tip assembly. If you need technical drawings or specifications, such as those for the TR20x2.0 LH thread, contacting the supplier can provide detailed support.
Benefits of Using the 36mm Nissei Free Flow Tip Assembly
Choosing the right tip assembly impacts your machine’s performance and product quality. The 36mm free-flow tip assembly offers several advantages:
Improved Material Flow
The free-flow design reduces resistance, allowing molten plastic to move smoothly through the tip, minimizing pressure fluctuations.
Reduced Wear and Tear
The 3-piece check valve design helps prevent backflow and contamination, extending the life of the tip assembly and screw.
Consistent Part Quality
Stable flow and pressure lead to uniform filling of molds, reducing defects and improving dimensional accuracy.
Easy Replacement
Designed as a standard replacement part, installation is straightforward, minimizing downtime.
