770-418-417-6983 /When working with plastic injection molding machines, the right components make all the difference. One key part that often gets overlooked is the tie bar. For those using Newbury machines, the 3.5-inch Newbury tie bar is a crucial element that ensures stability and precision during molding. This post explores what machines use this tie bar, why it matters, and how you can get your hands on one today.

3 and a half inch Newbury Tie Bar
A tie bar is a long, cylindrical rod that holds the platens of an injection molding machine together. It maintains the structural integrity of the machine under high pressure during the molding process. The 3.5-inch Newbury tie bar refers to the diameter of the tie bar, which is 3.5 inches. This size is specific to certain Newbury injection molding machines and is essential for compatibility and performance.
3 and a half inch Newbury Tie Bar - The overall length (OAL) of this tie bar is approximately 110.12 inches, making it suitable for machines with specific frame sizes and platen spacing.
Which Plastic Injection Machines Use the 3.5-inch Newbury Tie Bar?
Not all injection molding machines use the same tie bar size. The 3.5-inch Newbury tie bar fits particular models and series within the Newbury lineup. Here are some examples:
Newbury V3-80RS / V3-80BRS (80 Ton)
These machines are commonly listed with a 3.5-inch centerline tie bar specification. They are popular for medium-duty molding tasks and require tie bars that can handle moderate clamping forces.
Newbury 150-Ton Series (e.g., M6-6-150RS)
While these machines often have larger platen dimensions, some configurations within this series use tie bars with diameters and spacing that include 3.5-inch components. This depends on the specific stationary or moving platen assembly.
Custom and Heavy-Duty Newbury Vertical Series
These vertical machines often feature four tie-bar frames designed for high cavity counts and taller mold stacks. Some models within this series incorporate 3.5-inch tie bars to meet the demands of heavier molds and higher pressures.
Understanding which machine uses this tie bar helps in ordering the correct replacement or upgrade part, ensuring your machine runs smoothly without unexpected downtime.
Why the Right Tie Bar Size Matters
Choosing the correct tie bar size is not just about fitting the machine. It affects:
Machine Stability
The tie bar keeps the platens aligned and stable during injection. A smaller or larger diameter than specified can cause misalignment or excessive wear.
Mold Protection
Proper tie bar size helps distribute clamping force evenly, protecting molds from damage.
Machine Longevity
Using the right tie bar reduces stress on the machine frame, extending its operational life.
Safety
A correctly sized tie bar prevents mechanical failures that could lead to accidents.
