The 22mm Nissei screw, with an overall length of 18.43 inches, is a popular choice for many small to mid-range tonnage machines. This screw size supports a range of Nissei models designed for various applications, from high-precision parts to overmolding. If you need a dependable replacement or upgrade, www.completeplastics.com offers this screw ready for immediate purchase.
Why Choose a 22mm Nissei Screw?
The 22mm screw diameter is ideal for Nissei machines in the 30-ton to 80-ton range. This size balances injection volume and precision, making it suitable for applications requiring small to medium shot sizes. The screw length of 18.43 inches ensures adequate plasticizing capacity while maintaining consistent melt quality.
This screw size is especially favored in industries where tight tolerances and repeatability are essential, such as medical device manufacturing, electronics, and consumer goods.
Compatible Nissei Models Using the 22mm Screw
Several Nissei machines come standard or can be configured with a 22mm screw. Here are some notable models:
Horizontal All-Electric and Hybrid Models
NEX80IV-5EG / NEX80III-5EG
These 80-ton machines often use the 22mm screw for applications requiring high precision and low shot weight. The typical shot size is approximately 1.2 ounces, making them suitable for detailed parts with tight dimensional control.
NEX50-5E / NEX50-5VE
The 50-ton NEX series frequently employs the 22mm screw to deliver an injection capacity that fits mid-range production needs. These machines are versatile for various molding tasks.
FNX Series (Hybrid)
The FNX hybrid machines offer flexibility with different injection units. Many configurations support the 22mm screw, allowing users to tailor the machine to specific production requirements.
NS40-5A
This legacy hydraulic model uses the 22mm screw to maintain its standard shot capacity, providing reliable performance for older equipment still in operation.
Vertical Machines
TH60REV5E
A 60-ton vertical rotary machine often equipped with a 22mm screw. This setup is common for overmolding or insert molding, where precision and repeatability are critical.
ST10 / ST20 Series
These small tonnage vertical machines (10 to 20 tons) use the 22mm screw as their largest standard option. This maximizes injection volume while keeping the machine compact.
TNX50R
The 50-ton vertical rotary series lists the 22mm screw as a standard configuration, supporting a range of molding applications with moderate shot sizes.
Compatible Control Generations and Components
If you are sourcing replacement parts, the 22mm screw is compatible with several Nissei control generations, including:
Tact Series: Tact IV, Tact III, and the original Tact controllers.
NC Series: Older NC8300, NC9000, and NC9300 units.
This compatibility ensures that the screw fits a wide range of machines, making it easier to maintain and repair equipment without needing extensive modifications.
