Nissei Screws in Injection Molding - Order Now - sales@completeplastics.com

www.completeplastics.com / 770-417-6983. Injection molding machines rely heavily on precision components to deliver consistent, high-quality results. One such critical component is the Nissei screw, specifically the 26mm diameter screw with an overall length of 29.13 inches (approximately 740mm). This screw size is a key part of many smaller, high-precision Nissei vertical and horizontal injection molding machines, especially older models from the FN, FS, ES, and TH series.

Understanding the applications and compatibility of the 26mm Nissei screw can help manufacturers maintain and optimize their injection molding operations. This post explores the uses, compatible machine models, and ordering information for this essential component.

Nissei Screws in Injection Molding

The 26mm Nissei screw is designed for precision and durability. Its size and length make it ideal for smaller injection molding machines that require accurate material melting and injection control. The screw’s diameter affects the shot size and the pressure applied during injection, which directly influences the quality of molded parts.

The 29.13-inch overall length allows the screw to fit into specific machine barrels, ensuring proper plasticizing and injection cycles. This length is particularly common in older Nissei models, which are still widely used in many manufacturing facilities due to their reliability and performance.

Compatible Nissei Machine Models

The 26mm screw is compatible with several Nissei injection molding machines, especially those from the older series. Here are some examples:

• Nissei TNS50R5V (Vertical Clamp/Injection)

This 53-ton vertical machine from 2006 uses a 26mm screw diameter. It is known for its compact design and precise injection capabilities, making it suitable for small to medium-sized parts.

• Nissei TH Series Vertical Machines (e.g., TH40-5V, TH60-5V)

These vertical single-stage machines use 26mm screws. They are favored for their efficiency in vertical injection molding applications, often used in automotive and electronics industries.

• Nissei FN-D Series 2 Shot Machines (Secondary Side)

In models like the FN80-12AD, the 26mm screw is used as the secondary injection unit. This setup allows for two-shot molding, where two different materials or colors are injected sequentially to create complex parts.

These examples highlight the versatility of the 26mm screw across different machine types and molding processes.

Components and Accessories for 26mm Screws

When ordering a 26mm Nissei screw, it is important to consider compatible components that ensure optimal performance:

• 3-Piece Check Valves

These valves are designed to fit 26mm screws and help control the backflow of molten plastic during injection. Proper valve function improves shot consistency and reduces defects.

• Barrels and Sleeves

Matching barrels and sleeves designed for 26mm screws ensure proper fit and heat transfer, which are critical for maintaining material quality.

• Drive Keys and Couplings

These parts connect the screw to the motor and gearbox, transmitting torque efficiently. Using compatible drive components reduces wear and extends machine life.

Tips for Maintaining Your Nissei Screw

To maximize the lifespan and performance of your 26mm Nissei screw, consider these maintenance tips:

• Regular Inspection

Check for wear, corrosion, or damage on the screw flights and tip. Early detection prevents costly breakdowns.

• Proper Cleaning

Remove residual plastic and contaminants after each production run to avoid buildup that affects screw rotation.

• Use Compatible Materials

Ensure the screw material matches the plastics processed to prevent premature wear.

• Monitor Machine Settings

Maintain recommended temperatures and pressures to avoid excessive stress on the screw.
