sales@completeplastics.com / 770-417-6983. Injection molding machines rely heavily on precision components to deliver consistent, high-quality results. One critical part is the screw, which plays a vital role in melting, mixing, and injecting plastic material. For operators and maintenance teams working with Niigata injection molding machines, finding the right screw replacement can be challenging. The 45mm Niigata screw with an overall length of approximately 48.38 inches (1,229 mm) is a key component designed for specific Niigata models, offering reliable performance and compatibility.
This post explores the specifications, applications, and benefits of the 45mm Niigata screw, helping you understand why it’s a smart choice for your injection molding needs.
Key Specifications of the 45mm Niigata Screw
Understanding the dimensions and technical details of the 45mm Niigata screw helps ensure proper fit and function in your machine. Here are the main specifications:
Diameter: 45mm
Overall Length: Approximately 48.38 inches (1,229 mm)
L/D Ratio: Typically between 20:1 and 22:1, which is standard for general-purpose plasticizing
Stroke Length: Varies between 115mm and 160mm depending on the machine sub-model
The length-to-diameter (L/D) ratio is important because it affects the screw’s ability to melt and mix plastic efficiently. A ratio around 20:1 to 22:1 balances melting capacity with throughput, making this screw suitable for a wide range of molding tasks.
Compatible Niigata Injection Molding Machines
The 45mm screw is designed to fit several Niigata models, especially those in the 110-ton and 200-ton classes. Here are some examples:
MD110 Series
The Niigata MD110SIII is a popular 110-ton all-electric injection molding machine. It uses the 45mm screw to achieve a shot size of about 6.3 ounces, making it ideal for medium-sized parts with consistent quality.
MD200 Series
The Niigata MD200-SIV is a 200-ton machine built for heavy-duty applications. It also uses the 45mm screw, typically delivering shot sizes around 300 grams (10.1 to 10.6 ounces). This model suits larger or more complex parts requiring higher injection pressure.
Vertical Models
The Niigata MDVP110X series includes vertical injection molding machines that often feature 40mm or 45mm screw options. These machines excel in precision insert molding, where accuracy and repeatability are critical.
These machines benefit from the 45mm screw’s balance of size and performance, making it a versatile choice for various production needs.
