770-417-6983 / www.completeplastics.com. Injection molding machines rely heavily on precise components to deliver consistent, high-quality products. One such critical component is the screw, which plays a vital role in melting, mixing, and injecting plastic materials. The 40mm Nissei screw with an overall length of 42.20 inches stands out as a specialized part designed for several mid-range Nissei injection molding machines. This blog post explores the key features, compatible machines, and technical specifications of this screw, helping you understand why it’s an essential choice for your molding operations.
Machines Compatible with the 40mm Nissei Screw
The 40mm diameter screw with a 42.20-inch overall length is commonly used in several Nissei machine series. These machines benefit from the screw’s design, which supports efficient plasticizing and consistent shot sizes. Here are the main series and models where this screw fits:
FN Series (Horizontal)
Models such as FN1000-12A, FN1000-18A, FN2000-18A, FN2000-25A, and FN3000-25A often come equipped with 40mm screws. These machines are popular for general-purpose injection molding tasks.
FNX Series (Hybrid)
The FNX110-12A (123 US Ton) and FNX180-25A models use the 40mm GP (General Purpose) screw either as a standard or optional shot size. These hybrid machines combine hydraulic and electric features for improved efficiency.
NEX Series (Electric)
High-performance electric models like the NEX180 and NEX140-25E list the 40mm screw as a standard "Type Y" or "25E" diameter. These machines are known for precision and energy savings.
Vertical Machines
Certain vertical configurations, including the TNX-RIII and TH-EIV series (40-70 ton models), can be adapted with a 40mm screw to meet specific shot capacity requirements.
Understanding which machines use this screw helps ensure you select the right part for your equipment, minimizing downtime and maximizing productivity.
Key Technical Specifications of the 40mm Nissei Screw
The 40mm Nissei screw is engineered to meet the demands of mid-range injection molding machines. Its specifications reflect a balance between size, length, and performance:
Diameter: 40mm
This diameter is standard for many Nissei machines, providing a good balance between shot size and plasticizing efficiency.
Overall Length (OAL): 42.20 inches (approximately 1072mm)
The length corresponds to an L/D (length-to-diameter) ratio of about 18:1 or 20:1. This ratio is typical for general-purpose screws, offering effective melting and mixing of plastic materials.
Compatible Components:
The screw pairs with 3-piece screw tip assemblies, which include the tip, check ring, and seat. These components are designed for Nissei’s TR24 x 3.0mm left-hand (LH) thread patterns, ensuring a secure fit and reliable operation.
These specifications make the 40mm screw versatile for a range of molding applications, from standard plastics to more demanding materials requiring consistent plasticizing.
Why Choose the 40mm Nissei Screw?
Selecting the right screw for your injection molding machine affects product quality, cycle times, and machine longevity. The 40mm Nissei screw offers several advantages:
Consistent Shot Size
The screw’s diameter and length support stable shot volumes, reducing variability in molded parts.
Efficient Plasticizing
The L/D ratio allows thorough melting and mixing, which improves material homogeneity and reduces defects.
Compatibility with Multiple Models
Its design fits a variety of Nissei machines, making it a flexible choice for shops with diverse equipment.
Durability and Precision
Manufactured to strict standards, the screw and its tip assembly maintain performance over extended use.
These benefits translate into smoother production runs and better end-product quality, which are critical for injection molding operations.

Maintenance Tips for Your Nissei Screw
To maximize the lifespan and performance of your 40mm Nissei screw, consider these maintenance practices:
Regular Inspection
Check the screw and tip assembly for wear, corrosion, or damage. Early detection prevents poor molding quality.
Proper Cleaning
Remove residual plastic and contaminants after each production run to avoid buildup that can affect melting efficiency.
Correct Installation
Ensure the screw is installed according to manufacturer guidelines, including proper torque on the tip assembly.
Monitor Shot Size and Pressure
Changes in these parameters can indicate screw wear or damage, signaling the need for replacement or repair.
Following these steps helps maintain consistent molding performance and extends the service life of your screw.
