www.completeplastics.com, sales@completeplastics.com. When your injection molding machine needs a reliable replacement tip assembly, the 40mm Nissei free flow tip assembly stands out as a trusted choice. Designed specifically for machines with a 40mm screw diameter, this assembly ensures smooth plastic flow and consistent molding quality. Whether you operate a horizontal hybrid, all-electric, or vertical Nissei model, understanding the features and compatibility of this tip assembly can save you time and improve your production efficiency.
40mm Nissei Free Flow Tip Assembly
The 40mm Nissei free flow tip assembly is compatible with a wide range of Nissei injection molding machines that use a 40mm screw diameter. This includes several series and specific models, making it a versatile replacement part for many mid-range tonnage machines.
Compatible Machine Series
Horizontal Hybrid & Hydraulic Models
FNX, FNXIII, FN, FS, FE, ES, FV, and NS series use this tip assembly. These models often handle medium to high tonnage applications and benefit from the free flow design to maintain consistent plasticizing.
All-Electric Models
The NEX and NEXIII series, known for precision and energy efficiency, also use the 40mm tip assembly. These machines require reliable components to maintain their all-electric performance.
Vertical Models
Vertical machines such as TNXIII, PNXIII, and TH models use this tip assembly to support vertical injection molding processes with high accuracy.
Specific Machine Models with 40mm Screw Options
Within the Nissei lineup, the 40mm screw diameter is common in mid-range tonnage machines, typically around 100 to 110 tons. Some examples include:
FN Series
Models like FN1000-12A, FN1000-18A, FN2000-18A, FN2000-25A, and FN3000-25A.
PN/PNX Series
Hybrid machines such as the PNX 40-60 ton units, especially when equipped with the larger 40mm screw option.
Other Models
Older 40-ton specialized Nissei machines designed for high-plasticizing capacity may also use this diameter.
Technical Specifications to Consider for Replacement
When sourcing a replacement 40mm Nissei free flow tip assembly, matching the technical specifications to your existing setup is critical. Using the wrong size or thread can cause machine damage or poor molding results.
Overall Length (OAL)
The standard length is approximately 6.11 inches (155mm). The length ensures proper fit and alignment with the screw and barrel.
Nose Angle
The tip has a 20-degree angle, which is important for controlling the flow of molten plastic and preventing backflow.
Thread Type
Most 40mm Nissei tips use a TR24 x 3.0mm left-hand (LH) thread. Confirming this thread type avoids compatibility issues.
Material Options
Depending on your application, you can choose from:
- H-13 Tool Steel for general-purpose use.
- D-2 Steel for applications involving light glass-filled plastics.
- CPM 9V Steel for high wear and abrasion resistance, ideal for abrasive materials.
Why Choose the 3-Piece Check Valve Design?
The 40mm Nissei free flow tip assembly often features a 3-piece check valve design. This design improves the flow of molten plastic by reducing pressure loss and preventing backflow during injection. The benefits include:
Consistent Shot Quality
The check valve maintains steady pressure, resulting in uniform molded parts.
Reduced Wear
The design minimizes mechanical stress on the tip and screw, extending component life.
Easy Maintenance
The 3-piece assembly allows for straightforward disassembly and cleaning, reducing downtime.
