When working with plastic injection molding machines, having the right components is crucial for smooth operation and consistent production quality. One such component is the 2 5/16" New Britain end cap, a part that fits specific New Britain injection molding machines and their compatible models. Understanding which machines use this end cap and why it matters can save time, reduce downtime, and improve your manufacturing process.
What is a 2 5/16 New Britain End Cap?
The 2 5/16" end cap refers to the diameter of the front-end component that seals the barrel of an injection molding machine. This size is common in medium-tonnage New Britain machines, which are known for their reliability and versatility in molding thermoplastic and thermoset materials.
New Britain was a well-known brand in the injection molding industry, and although the brand itself is now largely supported by HPM or aftermarket suppliers, many of its parts remain in demand. The 2 5/16" end cap is a standard size that fits specific models and shot sizes, making it a key replacement part for maintenance and repairs.
Which Machines Use the 2 5/16 New Britain End Cap?
This end cap size is primarily used in New Britain machines within the 75-ton to 150-ton range. Here are some examples:
New Britain 150TP: A popular toggle-clamp machine that uses the 2 5/16" end cap for its barrel sealing.
New Britain 75-ton to 150-ton Models: Many machines in this tonnage range share similar barrel diameters, making the end cap size compatible across multiple units.
HPM/New Britain Hybrid Machines: After HPM acquired New Britain, many of their machines and parts became cross-compatible. This means the 2 5/16" end cap can fit both legacy New Britain machines and newer HPM models with matching barrel sizes.
Thermoset and Thermoplastic Units: Both types of molding machines from New Britain, such as the Model 300-30, use standardized front-end components. The 2 5/16" end cap is most common on smaller shot size machines like the 150-ton series.
Understanding this compatibility helps operators and maintenance teams source the correct parts without confusion or delay.
Why the Right End Cap Matters
The end cap seals the barrel front, holding the screw and barrel assembly tightly in place. If the end cap is worn, damaged, or the wrong size, it can cause:
Leaks of molten plastic, leading to material waste and safety hazards.
Poor pressure control, which affects the quality of molded parts.
Increased machine downtime due to frequent repairs or part replacements.
Misalignment of barrel components, causing uneven wear and potential machine damage.
Using the correct 2 5/16" New Britain end cap ensures the machine runs smoothly, maintains consistent shot sizes, and extends the life of the barrel and screw.

Tips for Maintaining Your New Britain End Cap
To maximize the lifespan of your 2 5/16" New Britain end cap, consider these maintenance tips:
Regular Inspection: Check for cracks, corrosion, or wear during routine machine maintenance.
Proper Installation: Ensure bolts are tightened to manufacturer specifications to avoid leaks or misalignment.
Use Compatible Parts: Stick to end caps designed for your specific machine model and shot size.
Clean After Use: Remove any plastic residue or debris to prevent buildup that can damage the seal.
Monitor Machine Performance: Changes in shot size consistency or pressure may indicate end cap issues.
Following these steps helps avoid unexpected downtime and costly repairs.
Understanding Shot Sizes and Barrel Diameters
The 2 5/16" measurement relates to the barrel diameter and correlates with the shot size of the machine. Medium-tonnage machines like the New Britain 150TP typically have shot sizes that match this barrel diameter, making the end cap size a critical specification.
Knowing your machine’s shot size and barrel diameter helps you order the correct end cap and other front-end components. If unsure, consult your machine manual or contact suppliers like Complete Plastics for guidance.
