What Makes the 26mm Nissei Screw Important?

The 26mm screw diameter is a standard size for many Nissei machines with clamping forces ranging from 20 to 121 tons. This size strikes a balance between shot size capacity and precision, making it ideal for producing small to medium plastic parts with tight tolerances. The screw length, typically around 24.32 inches overall, supports consistent melting and injection of plastic materials.

This screw size is versatile and found in various machine types, including:

• All-electric models for energy-efficient, high-precision molding

• Hybrid machines combining hydraulic and electric features

• Hydraulic models for traditional molding applications

• Vertical machines designed for insert molding and medical parts

  
  

Understanding which machines use the 26mm screw helps operators and maintenance teams source the right replacement parts and optimize machine settings.

Nissei All-Electric Machines Using the 26mm Screw

Nissei’s all-electric machines are known for precision, speed, and energy savings. Several models in the NEX series use the 26mm screw to deliver consistent shot sizes and high-quality parts.

• NEX 40: This 40-ton machine often comes equipped with a 26mm screw, making it suitable for small-part production with fast cycle times.

• NEX 80 (III/IV): The 80-ton model uses the 26mm screw for high-speed applications requiring tight dimensional control.

• NEX 110 (9E/IV-9EG): Machines in the 110 to 121-ton range use the 26mm screw for specific shot sizes, such as the 1.8 oz configuration, ideal for medium-sized parts.

  
  

These all-electric models benefit from the screw’s ability to maintain consistent melt quality and shot weight, which is critical for industries like electronics, medical devices, and automotive components.

Hybrid and Hydraulic Models Compatible with the 26mm Screw

Nissei’s hybrid and hydraulic machines also utilize the 26mm screw for mid-size precision molding. These machines combine the reliability of hydraulic systems with the efficiency of electric controls.

• FN Series (X-Pump): This hybrid series offers the 26mm screw for applications requiring precise control and moderate tonnage.

• DC120T (Two-Color): A specialty 120-ton machine designed for multi-material molding, it uses the 26mm screw to handle complex shot sequences.

• NS60-9A: A 70-ton hydraulic screw-type machine that supports the 26mm screw for consistent injection molding.

• Legacy 20-ton Hydraulic Machines: Older Nissei hydraulic models from around 1988 also used the 26mm screw, showing its long-standing reliability.

  
  

These machines are often chosen for their flexibility in molding different materials and multi-color parts, where the 26mm screw helps maintain shot consistency.

Vertical Machines and the 26mm Screw

Vertical clamping machines are specialized for insert molding and medical applications where precision and cleanliness are critical. The 26mm screw fits well in these machines, providing the right shot size and control.

• TNX / TNS Series: Models like the TNX50R can be fitted with a 26mm screw unit, making them suitable for molding inserts or small medical components with high accuracy.

  
  

Vertical machines benefit from the screw’s ability to deliver precise shot volumes in compact spaces, supporting industries that demand tight quality standards.

Practical Tips for Using and Maintaining the 26mm Nissei Screw

To get the most from your 26mm Nissei screw, consider these practical tips:

• Regular Inspection: Check the screw for wear, especially on the flights and tip. Worn screws can cause inconsistent shot weights and poor melt quality.

• Proper Cleaning: Use appropriate cleaning agents to remove residue without damaging the screw surface.

• Correct Screw Length: Ensure the overall length matches your machine’s specifications (around 24.32 inches) to maintain proper injection stroke and melt volume.

• Material Compatibility: Match the screw design to the materials you mold. Some screws are optimized for specific plastics like ABS, PP, or engineering resins.

• Timely Replacement: Replace screws before wear affects part quality or causes machine downtime.
