Newbury Tie Bar Nut - Call Now - 770-4127-6983

www.completeplastics.com / When working with plastic injection molding machines, having the right parts is essential for smooth operation and safety. One critical component in many Newbury injection molding machines is the 3.5" Newbury tie bar nut. This part plays a key role in securing the tie bars that hold the machine’s platens together during the molding process. Understanding which machines use this specific tie bar nut helps operators and maintenance teams source the correct replacement parts quickly and avoid costly downtime.

What Is a 3.5" Newbury Tie Bar Nut?

The tie bar nut is a heavy-duty fastener designed to fit onto the threaded ends of tie bars in injection molding machines. Tie bars are long steel rods that run through the machine’s frame, holding the stationary and moving platens in alignment. The nut secures the tie bar in place, maintaining the clamping force needed to keep molds closed during injection.

The 3.5" size refers to the diameter of the tie bar that the nut fits. This size is common on larger Newbury machines, where the clamping force requirements are higher due to bigger molds and larger shot sizes.

Which Newbury Machines Use the 3.5" Tie Bar Nut?

Based on industrial parts listings and machine specifications, the 3.5" Newbury tie bar nut is typically found on larger capacity Newbury vertical and horizontal injection molding machines. Here are the main machine categories that use this size:

Newbury 150-Ton Models

The 150-ton series is the primary line associated with the 3.5" tie bar nut. Models such as the Newbury V9-150ARS and M6-6-150RS commonly use this hardware. These machines require strong clamping force to handle medium to large molds, making the 3.5" nut a standard part of their clamping assemblies.

High-Tonnage Vertical Presses (150 to 200 Tons)

Newbury machines in the 150 to 200-ton range often use the 3.5" tie bar nut to manage the clamping forces needed for larger platens and shot sizes. These presses are designed for heavy-duty molding applications, where durability and precision are critical.

Smaller Machines Use Smaller Nuts

For comparison, Newbury presses in the 30 to 80-ton range, such as the V3-80BRS or V2-30ARS, typically use smaller diameter tie bars and nuts. The 3.5" nut is not common on these smaller machines because their clamping force requirements are lower.

Why Choosing the Correct Tie Bar Nut Matters

Using the correct tie bar nut size is crucial for several reasons:

• Safety: The tie bar nut holds the tie bar under extreme clamping pressure. An incorrect size can lead to failure, risking injury and equipment damage.

• Machine Performance: Proper fit ensures consistent clamping force, which affects mold quality and cycle times.

• Durability: The right nut size matches the tie bar strength, preventing premature wear or breakage.

• Ease of Maintenance: Standardized parts simplify repairs and reduce machine downtime.
