What Is a 36mm Nissei End Cap?


The 36mm Nissei end cap is a precision-machined part designed to fit the screw assembly of certain Nissei injection molding machines. It typically features a 3.16-inch width and a 10-hole bolt pattern with an outer diameter of about 120mm. The end cap secures the screw in place and ensures proper alignment during the injection molding process.


This component is essential for maintaining the integrity of the screw assembly, which directly affects the quality of molded parts and the efficiency of the machine.


Machines That Use the 36mm End Cap


The 36mm end cap is compatible with a range of Nissei machines, especially those in the FN Series and some NEX Series models. Here are some specific examples:


  • FN Series:

- FN80-18A

- FN110-18A

- FN1000-12A

- FN1000-18A

- FN2000-18A


  • NEX Series:

- Various NEX-IV and NEX-V models equipped with 36mm screw diameters


  • Vertical and Specialty Machines:

- Nissei PS40 (1994 model)

- Similar vertical injection molding machines


  • General Compatibility:

- FS, FE, ES, FNX, and TNX models also list compatibility with 36mm components

Knowing which machines use this end cap helps in ordering the correct part and avoiding downtime caused by incorrect components.


Key Specifications of the 36mm Nissei End Cap


Understanding the technical details of the end cap can help you verify compatibility and ensure proper installation:


  • Screw Size: 36mm diameter

  • Bolt Pattern: 10 holes arranged in a circle with approximately 120mm outer diameter

  • Thread Pitch: Usually a trapezoidal thread, such as M44 x 3 LH (left-hand thread), but this can vary depending on the injection unit configuration


These specifications are critical for matching the end cap to the screw and machine model. Using the wrong thread pitch or bolt pattern can cause damage or poor machine performance.


Why Choose the Right End Cap?


Using the correct 36mm Nissei end cap ensures:


  • Proper Screw Alignment: Prevents wobbling or misalignment that can cause wear or damage

  • Secure Fit: The 10-hole bolt pattern provides a strong, stable connection

  • Machine Longevity: Reduces stress on the screw and barrel, extending the life of your injection molding machine

  • Consistent Part Quality: Stable screw operation leads to uniform melting and injection, improving molded part consistency


Incorrect or worn end caps can lead to costly repairs and production delays.


Where to Buy 36mm Nissei End Caps


For reliable parts, consider suppliers specializing in injection molding machine components. One trusted source is Complete Plastics. They offer genuine 36mm Nissei end caps and related parts with expert support.


Ordering from a reputable supplier ensures you get parts that meet exact specifications and quality standards.


Installation Tips for the 36mm End Cap


Proper installation is key to maximizing the performance of your end cap:


  • Inspect the End Cap and Screw: Check for any damage or wear before installation

  • Clean Contact Surfaces: Remove debris or old lubricant to ensure a tight fit

  • Align Bolt Holes Carefully: Match the 10-hole bolt pattern precisely to avoid cross-threading

  • Use Correct Torque Settings: Follow manufacturer guidelines to avoid over-tightening or loosening

  • Check Thread Pitch Compatibility: Confirm the thread pitch matches your screw assembly


Following these steps helps prevent premature failure and keeps your machine running efficiently.


Signs You Need a New 36mm End Cap


Watch for these indicators that your end cap may need replacement:


  • Visible Wear or Cracks: Any damage to the bolt holes or screw interface

  • Loose Fit: If the end cap does not secure tightly to the screw

  • Unusual Noise or Vibration: During machine operation, indicating misalignment

  • Decreased Part Quality: Inconsistent molding results linked to screw issues


Replacing worn end caps promptly avoids more serious machine damage.


Summary


The 36mm Nissei end cap is a vital component for many Nissei injection molding machines, especially in the FN and NEX series. Its precise dimensions, including a 3.16-inch width and 10-hole bolt pattern, make it essential for securing the screw assembly and maintaining machine performance. Knowing which models use this end cap and understanding its specifications helps you order the right part and keep your equipment running smoothly.
