Compatible Nissei Machine Models
The 22mm screw is widely used across several Nissei machine lines, especially those designed for high precision and smaller shot sizes. Here are some of the key models that commonly use this screw:
NEX30Ⅳ-1EN1 (2-stage type)
This model is popular in medical and micro-molding applications where precision is critical. The 22mm screw supports low shot weights, typically around 1.2 ounces, making it ideal for delicate parts.
NEX80Ⅳ-5EG (2018 models)
These machines often come equipped with the 22mm screw to ensure precise injection control. The screw size supports consistent melt flow and shot accuracy.
NEX-V Series (30tf-80tf)
The modern all-electric NEX-V series uses the 22mm screw, often referred to as the "A" screw, with a capacity around 35cm³. This series is known for high performance and energy efficiency.
PNX 40-60 tons (Hybrid machines)
Hybrid models in this tonnage range typically use the 22mm screw, designated as Standard 5A, combining electric injection with hydraulic clamping.
TNX-RⅢ Series (Vertical machines)
Vertical injection molding machines in this series also use specific 22mm A-screw configurations tailored for vertical molding applications.
These models highlight the versatility of the 22mm screw across different machine types and applications.
Key Features of the 22mm Nissei Screw
Understanding the features of the 22mm Nissei screw helps explain why it is preferred for certain molding tasks:
Diameter and Length
The 22mm diameter combined with a 22.44-inch overall length suits low shot weight molding, typically around 1.2 ounces. This size balances melt volume and injection speed for precise control.
Material Options
Nissei stocks these screws in high-wear materials such as CPM 9V, H13, and D2 tool steels. These materials provide excellent resistance to abrasion and corrosion, extending screw life in demanding production environments.
Tip Compatibility
The 22mm screws use specialized 3-piece free-flow screw tip assemblies. These tips improve melt flow and reduce shear, which is essential for molding delicate or technical parts.
Precision and Performance
The screw design supports consistent melt temperature and pressure, which is critical for repeatable molding quality. This is especially important in medical, micro, and technical molding where tolerances are tight.
Applications and Benefits
The 22mm Nissei screw is ideal for industries and applications that demand precision and reliability:
Medical and Micro-Molding
Small, intricate parts require precise shot control and consistent melt quality. The 22mm screw’s size and tip design support these needs.
Technical and Specialty Parts
Parts with complex geometries or tight tolerances benefit from the screw’s ability to maintain stable melt conditions.
Low Shot Weight Production
The screw’s capacity matches low shot volumes, reducing material waste and improving cycle times.
Hybrid and All-Electric Machines
The screw fits both hybrid and all-electric Nissei machines, offering flexibility for manufacturers upgrading or maintaining their equipment.
