www.completeplastics.com, sales@completeplastics.com. Injection molding machines rely heavily on the precision and durability of their screws to deliver consistent, high-quality production. Among these components, the 90mm Nissei screw stands out as a key part for large-tonnage machines, especially those in the 500 to 700-ton range. This blog post explores the applications, compatibility, and benefits of the 90mm Nissei screw, helping you understand why it’s a critical choice for your injection molding needs.
What Makes the 90mm Nissei Screw Essential?
The 90mm screw diameter is designed for machines that require a balance between high injection capacity and pressure control. This size is common in large-tonnage Nissei injection molding machines, which handle bigger shot volumes and tougher materials. The screw’s length, often around 80.83 inches overall, allows for efficient melting and mixing of plastic resins, ensuring uniformity in the molded parts.
Using the right screw diameter affects:
Shot volume: Larger screws can inject more material per cycle.
Injection pressure: Proper sizing helps maintain optimal pressure for quality molding.
Cycle time: Efficient melting reduces cycle times, improving productivity.
Material compatibility: Different plastics require specific screw designs for best results.
Nissei Machine Models That Use 90mm Screws
Several Nissei machine series and models are compatible with 90mm screws, especially those designed for high-capacity injection molding.
FV Series (Large Tonnage)
The FV series is known for its large-tonnage machines, often equipped with 90mm screws to handle heavy-duty production.
FV560-210L
This model offers an injection capacity of approximately 2,670 cm³, making it suitable for large parts. The 90mm screw option enhances its ability to process high volumes efficiently.
FV560-310L
Available with a 90mm screw as either a standard or optional feature, this machine balances shot size and injection pressure for versatile molding applications.
FV9000
A 618-ton horizontal machine, the FV9000 can be fitted with a 90mm screw to achieve a shot size of about 105 ounces, ideal for large, complex parts.
FN Series
While smaller FN series machines use smaller screws, the high-capacity units in this series can be configured with 90mm screws, especially those with high-pressure injection units. This flexibility allows manufacturers to tailor the machine’s performance to specific production needs.
Other Compatible Series
Replacement 90mm screw tip assemblies and barrels are also available for a wide range of Nissei models, including:
FE Series
ES Series
NS Series
FNX Series
NEX Series
PNXIII Series
TH Series
Compatibility depends on the injection unit size, but many of these series support 90mm screws for larger injection units.
Choosing the Right Screw for Your Nissei Machine
Selecting the correct screw diameter is crucial for balancing injection pressure and shot volume. Many Nissei machines offer options for small, medium, or large screws within the same model. This flexibility allows manufacturers to optimize their machines for different materials and part sizes.
When deciding on a 90mm screw, consider:
Material type: Some plastics require longer screws or specific designs for proper melting.
Part size and complexity: Larger parts need bigger shot volumes, which a 90mm screw can provide.
Cycle time requirements: Efficient screw design can reduce cycle times without sacrificing quality.
Machine tonnage: Ensure the machine’s clamping force matches the screw’s injection capacity.
Benefits of Using a 90mm Nissei Screw
Investing in a 90mm screw for your Nissei injection molding machine offers several advantages:
Increased shot capacity for larger parts or higher production volumes.
Improved melt homogeneity, leading to better part quality.
Enhanced machine versatility by allowing different screw sizes for various applications.
Reduced wear and tear with high-quality materials and precise manufacturing.
Availability of replacement parts through suppliers like Complete Plastics, ensuring minimal downtime.
