770-417-6983 / www.completeplastics.com. When your plastic injection molding machine needs a reliable replacement barrel, choosing the right size and model is critical. The 60mm Negri Bossi barrel is a popular choice for many mid-range machines, offering a balance of performance and versatility. This post explains which Negri Bossi machines use a 60mm barrel, why this size is common, and how to order OEM-spec barrels from trusted suppliers like Complete Plastics.
What is a 60mm Negri Bossi Barrel?
A 60mm barrel refers to the diameter of the screw and cylinder used in plastic injection molding machines. This size is widely used in machines with clamping forces ranging from 160 to 370 tonnes. The barrel plays a key role in melting and injecting plastic material into molds, so its dimensions must match the machine’s specifications for optimal performance.
The overall length (OAL) of a typical 60mm Negri Bossi barrel is about 45.748 inches, ensuring compatibility with various mid-sized machines. Using the correct barrel size helps maintain consistent shot quality, reduces wear, and improves the lifespan of your injection molding equipment.
Negri Bossi Machines That Use a 60mm Barrel
Several Negri Bossi models are designed to work with a 60mm barrel and screw configuration. These machines cover a range of clamping forces and production needs:
VE-370
This model explicitly supports a 60mm screw and cylinder. It is designed for medium to large production runs where precision and reliability are essential.
NB 300
Part of the older NB series, the NB 300 features a 60mm screw diameter. It remains popular for its robust build and consistent performance in 300-tonne clamping force applications.
V320
The V320 is a 320-tonne machine often equipped with 60mm injection components. It suits manufacturers needing a balance between shot size and machine power.
250 Ton Models
Various 250-tonne Negri Bossi machines have been configured with 60mm barrels. These models are common in industries requiring moderate shot sizes and efficient cycle times.
NOVA sT / NOVA 5eT Series
The modern NOVA series machines, ranging from 180 to 360 tonnes, offer customizable injection units. The 60mm barrel is a standard option for mid-sized shot requirements, providing flexibility for different molding tasks.
Why Choose a 60mm Barrel for Your Machine?
The 60mm barrel size is a practical choice for many injection molding applications because it offers:
Versatility
Suitable for a wide range of materials and shot sizes, the 60mm barrel fits machines that handle medium to large parts.
Availability
Replacement barrels and screws in this size are widely available from OEM and aftermarket suppliers, making maintenance easier.
Performance
