770-417-6982 / sales@completeplastics.com. Injection molding machines rely heavily on the precision and compatibility of their components. One critical part is the barrel, which directly affects the machine’s performance and the quality of molded parts. The 35mm Niigata barrel, with an overall length of 34.92 inches, is a popular choice for many Niigata injection molding machines. This post explores which machines use this barrel, its applications, and why it remains a preferred option for small to mid-range molding needs.
What Is a 35mm Niigata Barrel?
The 35mm Niigata barrel is a key component designed for Niigata injection molding machines. It features a screw diameter of 35 millimeters and a length of 34.92 inches. This size is commonly used in machines that require precise control over shot volume and injection pressure, especially in the small to mid-range clamp force category, typically between 55 tons and 110 tons.
The barrel works by housing the screw that melts and pushes plastic material into molds. Its diameter and length influence the machine’s shot capacity, injection speed, and pressure, making it essential to match the barrel size with the machine’s intended application.
Machines That Use the 35mm Niigata Barrel
Niigata manufactures a variety of injection molding machines, and the 35mm barrel fits several of their models. These machines fall into three main categories:
1. MD Series (All-Electric Machines)
The MD Series represents Niigata’s flagship line of all-electric injection molding machines. These machines are known for energy efficiency, precision, and clean operation. The 35mm barrel is a standard or optional feature in several models within this series:
MD55 / MD55S / MD55W
These 55-ton machines often use either 28mm or 35mm barrels depending on the shot volume and injection pressure needed. The 35mm barrel offers a good balance for moderate shot sizes.
MD85 / MD85S
The 85-ton models frequently come equipped with a 35mm barrel. This size supports a balanced shot capacity suitable for a wide range of molding tasks.
MD110 / MD110S
While larger barrels like 40mm or 45mm are common on the 110-ton frame, the 35mm barrel is preferred for high-pressure, precision molding of smaller parts.
MD-S8000 Series
The latest 8th generation all-electric machines, such as the MD110-S8000, support multiple screw and barrel sizes, including 35mm, to meet diverse production needs.
2. MDVR / MDVP Series (Vertical Rotary Machines)
Niigata leads in vertical injection molding machines, especially for insert molding applications. The vertical rotary models in the 110-ton range often use 35mm or 40mm barrels:
MDVR-110 / MDVP-110
These vertical rotary machines utilize the 35mm barrel to deliver precise injection control, which is critical for insert molding where components must be accurately placed and molded around.
3. Legacy Series (Older Hydraulic and Early Electric Machines)
Many older Niigata machines still in operation require replacement barrels. The 35mm barrel fits several legacy models:
NN Series
Older hydraulic machines like the NN100 or NN110 often use 35mm barrels for maintenance and replacement.
MD-S / MD-X Series
Early electric machines from these series also commonly use 35mm barrels, making this size essential for servicing and parts replacement.
Why Choose a 35mm Niigata Barrel?
Choosing the right barrel size impacts molding quality, machine efficiency, and production consistency. The 35mm Niigata barrel offers several advantages:
Versatility
It fits a wide range of machines from 55 to 110 tons, covering many production requirements.
Precision
The barrel supports high-pressure injection molding, ideal for small, detailed parts.
Compatibility
It works with both all-electric and hybrid machines, including vertical rotary models.
Availability
Because it is a common size, replacement barrels and screws are easier to source, reducing downtime.
Applications of Machines Using the 35mm Niigata Barrel
Machines equipped with the 35mm barrel handle various molding tasks across industries:
Automotive Components
Small to medium-sized parts requiring tight tolerances.
Medical Devices
Precision molding of plastic parts where contamination control is critical.
Consumer Electronics
Housing and internal components with detailed features.
Insert Molding
Vertical rotary machines with 35mm barrels excel in insert molding, combining plastic with metal or other materials.
