What is a 26mm Nissei End Cap?

A 26mm Nissei end cap is a component used on plastic injection molding machines that have a 26mm screw diameter. This end cap fits onto the barrel assembly, sealing and supporting the screw during the injection process. It features six holes for secure attachment, ensuring stability and alignment.

These end caps are essential for machines that operate in the smaller tonnage range, typically found in both horizontal and vertical injection molding setups. The 26mm size is common in precision molding applications where smaller parts or detailed components are produced.

Compatible Nissei Machine Series and Models

Nissei offers a range of injection molding machines, and the 26mm end cap fits specific series and models. Understanding which machines use this size helps in selecting the right replacement part or upgrade.

Horizontal All-Electric and Hybrid Series

• NEX-V Series

Models like the NEX80V and NEX110V, especially when equipped with the "9E" or "AA" high-pressure injection units, use 26mm screws and end caps. These machines are known for their precision and efficiency in small to medium part production.

• NEX-III and NEX-IV Series

These electric machines often operate in the 50 to 110-ton range and rely on 26mm screws and matching end caps for consistent molding quality.

• FNX Series

Hybrid machines such as the FNX80 and FNX110 may use the 26mm assembly depending on the injection unit selected, often the "8A" or "9A" variations. These models balance electric and hydraulic power for versatile molding needs.

Vertical Injection Series

• TH-EIII and TH-EIV Series

Vertical machines like the TH40EIII and TH70EIII commonly use a 26mm screw diameter with the 5VE injection unit. These are popular for insert molding applications where precision and repeatability are critical.

• TNX and TNS Series

Both older and current vertical hybrid models, including the TNX50R and TNS50R, frequently feature 26mm screws and end caps. These machines are valued for their reliability in vertical molding tasks.

Why the Right End Cap Matters

Using the correct 26mm Nissei end cap is vital for several reasons:

• Machine Performance

The end cap ensures proper sealing and alignment of the screw, which affects the injection pressure and material flow. A worn or incorrect end cap can cause leaks, inconsistent shot sizes, or damage to the screw and barrel.

• Product Quality

Consistent molding depends on stable screw rotation and injection pressure. The right end cap helps maintain these conditions, reducing defects like short shots, flash, or burn marks.

• Machine Longevity

Proper fit and secure attachment reduce wear on the screw and barrel assembly. This extends the life of expensive machine components and lowers maintenance costs.

• Safety

A secure end cap prevents material leakage and mechanical failures that could pose safety risks to operators.

How to Choose and Source a 26mm Nissei End Cap

When selecting a 26mm Nissei end cap, consider the following:

• Compatibility

Verify the machine model and injection unit type to ensure the end cap matches the screw diameter and hole pattern.

• Quality

Choose end caps made from durable materials that withstand high pressure and temperature conditions typical in injection molding.

• Supplier Reliability

Work with trusted suppliers who provide genuine or high-quality replacement parts. This reduces the risk of premature failure.

Installation Tips for the 26mm Nissei End Cap

Proper installation ensures optimal performance:

• Clean the screw and barrel assembly before fitting the new end cap.

• Align the six holes precisely with the mounting points.

• Use the correct torque settings on bolts to avoid over-tightening or loosening during operation.

• Inspect the end cap regularly for signs of wear or damage.

  
  

Following these steps helps maintain machine efficiency and reduces downtime.
