www.completeplastics.com / 770-417-6983. Finding the right injection molding screw can be a challenge, especially when you need a specific size and length for your Nissei machine. The 30mm Nissei screw with an overall length of 24.39 inches (approximately 619.5 mm) is a key component for many smaller Nissei injection molding machines. This post will guide you through the details of this screw, its common applications, compatible machine models, and how to ensure you get the right fit for your equipment.
Understanding the 30mm Nissei Screw
The 30mm diameter screw is designed primarily for smaller Nissei plastic injection molding machines. Its overall length of 24.39 inches (about 619.5 mm) makes it suitable for machines that require precise and consistent plasticizing and injection performance.
Why This Size Matters
Precision molding: Smaller screws like the 30mm diameter are ideal for high-precision molding tasks, especially when working with low gram weights.
Machine compatibility: This screw size fits well within Nissei's smaller machine series, ensuring optimal performance without overloading the system.
Versatility: It works across electric, hybrid, and vertical injection molding machines, making it a flexible choice for various production needs.
Common Nissei Machine Series Using 30mm Screws
The 30mm screw with a 24.39" overall length is often found in several Nissei machine series, including:
PNX Series: Known for compact and efficient molding machines in the 30-ton to 60-ton range.
FNX Series: Hybrid models that combine hydraulic and electric features.
NEX Series: All-electric machines designed for precision micro-molding, especially in the 30-ton to 50-ton capacity range.
These series are popular for their reliability and precision, making the 30mm screw a critical part of their operation.
Specific Compatible Machine Models
Here are some Nissei models that commonly use the 30mm screw with a 24.39" overall length:
NEX30V / NEX30IV (NEX30-1EN1)
These are 30-ton all-electric machines designed for ultra-stable, low-gram-weight molding. The 30mm screw helps maintain consistent melt quality and shot accuracy.
NS40E5A
A 44-ton hybrid model combining hydraulic and electric systems. The 30mm screw supports efficient plasticizing and injection with reduced cycle times.
NEX80IV-5EG
An 88-ton electric machine that may use the 30mm screw for specific high-pressure molding applications requiring fine control.
Choosing the Right Screw for Your Machine
Selecting the correct screw involves more than just matching diameter and length. Here are key factors to consider:
Flight length and design: Screws come in various designs such as general purpose (GP), mixing, or barrier screws. Each design affects melting efficiency and material homogeneity.
Machine generation: Different generations of Nissei machines may have slight variations in screw specifications.
Material compatibility: Consider the type of plastic resin you will process, as some screws are optimized for specific materials.
Because of these variables, it is best to verify your screw requirements with a Nissei dealer or consult your machine’s OEM documentation using the 24.39" measurement as a reference.
