36mm to 28mm Nissei Spline Adapter - Available Now - www.completeplastics.com

770-417-6983 / sales@completeplastics.com. Injection molding machines require precise components to maintain performance and reliability. One common challenge is adapting parts between different screw diameters, especially when upgrading or maintaining Nissei machines. The 36mm to 28mm Nissei spline adapter offers a practical solution for users needing to connect components designed for different screw sizes. This post explains the adapter’s role, compatibility, and technical details to help you make informed decisions for your injection molding setup.

Why Use a 36mm to 28mm Nissei Spline Adapter?

Injection molding machines often use screws and end caps sized to specific diameters. Nissei machines, in particular, have models that use 32mm screws and corresponding end caps, but some applications require adapting between 36mm and 28mm sizes. This adapter allows:

• Compatibility between different screw sizes without replacing the entire screw or end cap assembly.

• Cost savings by enabling reuse of existing components.

• Simplified maintenance by reducing the need for custom parts or machine modifications.

  
  

If your machine or project involves transitioning between 36mm and 28mm screw diameters, this spline adapter is essential for smooth operation.

Compatibility with Nissei Injection Molding Machines

Nissei machines use various screw diameters depending on the model and series. The 32mm screw size is common in many models, but 36mm and 28mm sizes also appear in specific configurations. Understanding which machines use these sizes helps determine when the spline adapter is necessary.

Common Nissei Models Using 32mm Screws

• FN Series (12A injection unit): Includes models like the FN1000-12A (FN 80), a hydraulic machine with a 32mm screw diameter.

• NEX Series: Electric models such as the NEX110-9E (2007) with a 32mm screw.

• FNX Series: Includes the FNX110-18A, an "N-PLAjet" spec machine.

• Other series compatible with 32mm screws include FS, FE, ES, FN, FV, NS, FNXIII, NEXIII, PNXIII, TNXIII, and TH models.

  
  

When the Adapter is Needed

Machines or components with 36mm screws may not directly fit parts designed for 28mm screws. The spline adapter bridges this gap, allowing components like end caps, screw tips, or assemblies to connect securely.

Technical Specifications of the Adapter and Related Components

The spline adapter is designed to match the spline profiles of Nissei screws and end caps, ensuring a tight fit and reliable torque transfer. Key technical details include:

• Spline sizes: Adapts from 36mm to 28mm diameters.

• Material: Typically made from hardened steel or nitrided 4140/HT steel for durability and wear resistance.

• Design: Precision-machined splines to match Nissei standards.

• Use case: Fits between screw and end cap or screw tip assemblies.

  
  

Related Components

• 32mm Nissei End Caps: Often made from nitrided steel, these end caps fit 32mm screws and are sold as part of 3-piece free-flow screw tip assemblies.

• Screw Tip Assemblies: These include the screw tip, end cap, and adapter components to ensure smooth material flow and machine operation.

  
  

Benefits of Using the 36mm to 28mm Nissei Spline Adapter

• Improved machine flexibility: Allows mixing and matching of components across different screw sizes.

• Reduced downtime: Quick installation means less machine idle time during maintenance or upgrades.

• Cost efficiency: Avoids the need to purchase entirely new screws or end caps.

• Enhanced durability: Made from high-quality materials to withstand injection molding stresses.

Practical Example: Using the Adapter with an FN1000-12A Machine

The FN1000-12A (FN 80) is a popular hydraulic Nissei machine using a 32mm screw. Suppose you have a 36mm screw tip assembly but want to use a 28mm end cap or vice versa. Installing the 36mm to 28mm spline adapter allows these parts to connect without modification to the machine or components.

This flexibility can be critical in production environments where parts availability or cost constraints require creative solutions.
