www.completeplastics.com / 770-417-6983. Finding the right screw for your Nissei injection molding machine can be challenging. The 36mm Nissei screw stands out as a reliable choice for many models, offering consistent performance across various machine types. Whether you operate legacy hydraulic units or modern hybrid machines, this screw size fits a broad range of applications. This post explains why the 36mm screw is essential, which machines it suits, and how to order the correct part for your needs.
Why the 36mm Nissei Screw Matters
The 36mm screw is a standard diameter for Nissei injection units, typically labeled as 18A or 36A. This size has proven its value over many years and across multiple machine generations. It balances the need for precision injection with durability, making it a preferred choice for machines with clamping forces between 80 and 200 tons.
Using the correct screw size affects the quality of molded parts, cycle times, and machine efficiency. A screw that fits well ensures proper melting, mixing, and injection of plastic materials. The 36mm diameter is versatile enough to handle a variety of resins and production demands without compromising performance.
Compatible Nissei Machine Models
The 36mm screw fits several Nissei machine series, including hydraulic, hybrid, and electric models. Here are some key examples:
FN Series (Hydraulic/Hybrid)
Models like FN1000-12A, FN1000-18A, FN2000-18A, and FN-4000-36A use the 36mm screw. These machines cover a range of clamping forces and are common in many production environments.
FNX Series (Hybrid)
The FNX140-36A, FNX180-36A, and the third-generation FNX140III-36A models also rely on this screw size. These hybrid machines combine hydraulic and electric features for improved energy efficiency.
Vertical Series
Large vertical hybrid machines such as the TWX300RIII36V and vertical types like the TD200-36ASE use the 36mm screw. Vertical machines often require precise injection control, which this screw supports.
Legacy and Other Series
Older models like the PS40 (a 40-ton legacy machine) and various units in the FS, FE, ES, FV, NS, NEX, PNX, TNX, and TH series also utilize the 18A or 36A injection units with this screw diameter.
This broad compatibility means that if you operate multiple Nissei machines or plan to upgrade, the 36mm screw can serve as a common replacement part, simplifying maintenance and inventory.
Technical Details and Considerations
Understanding the technical context helps ensure you order the right screw for your machine:
Injection Unit Size
In Nissei’s naming system, the number after the hyphen often indicates the injection unit size. The 36mm bore corresponds to the 18A and 36A units, which are standard across many models.
Screw Length and Design
While the diameter is consistent at 36mm, the overall length and shank design can vary depending on the machine series. For example, an FN series screw may differ in length or mounting features from an NEX series screw. The typical overall length for the 36mm screw discussed here is 39.05 inches.
Material and Wear Resistance
Screws are usually made from hardened steel or alloy materials designed to resist wear from abrasive plastics and high temperatures. Choosing a screw from a reputable supplier ensures quality and longevity.
Interchangeability
Although the diameter is the same, always verify compatibility with your specific machine model. Differences in screw pitch, flights, or tip design can affect performance.

Benefits of Choosing the Right Screw
Selecting the correct 36mm Nissei screw offers several advantages:
Improved Part Quality
Proper screw fit ensures consistent melting and mixing, reducing defects like short shots or burn marks.
Reduced Downtime
Using the right screw minimizes wear and tear on the injection unit, lowering maintenance frequency.
Cost Savings
A durable screw reduces replacement costs and improves machine uptime, boosting overall productivity.
Compatibility Across Machines
The 36mm screw’s use in multiple Nissei models simplifies inventory management for facilities with diverse equipment.
Tips for Maintaining Your Nissei Screw
To extend the life of your 36mm screw, consider these maintenance practices:
Regular Inspection
Check for wear, corrosion, or damage. Early detection prevents costly failures.
Proper Cleaning
Remove residue and buildup after production runs to maintain smooth operation.
Use Compatible Materials
Avoid abrasive or corrosive plastics that can accelerate screw wear.
Follow Manufacturer Guidelines
Adhere to recommended torque and installation procedures to avoid damage.
Summary
The 36mm Nissei screw is a key component for many injection molding machines, especially those with clamping forces between 80 and 200 tons. Its wide compatibility across hydraulic, hybrid, vertical, and legacy Nissei models makes it a versatile choice. Knowing the correct dimensions and machine compatibility ensures you get the right part for your needs.
