www.completeplastics.com / 770-417-6983. Plastic injection molding machines rely heavily on the precision and quality of their screws. The 40mm Niigata screw with an overall length of 48.50 inches is a key component for several Niigata models, ensuring consistent performance and high-quality molding results. Understanding which machines use this specific screw helps operators and maintenance teams source the right parts quickly and keep production running smoothly.
Which Niigata Machines Use the 40mm Screw?
The 40mm diameter screw with a 48.50-inch overall length fits several Niigata plastic injection molding machines. These machines vary in tonnage and application but share the need for this specific screw size to achieve optimal injection performance.
Niigata MD100 Series (All-Electric)
The MD100 series, including the MD100X and MD100XB models, are all-electric machines designed for precision and energy efficiency. These models use a 40mm screw (Type B), which supports a shot capacity of approximately 162 grams (5.7 ounces). This screw size balances shot volume and injection speed, making it ideal for small to medium-sized parts.
Niigata MD130 Series
The MD130S6000 model offers flexibility with a 40mm screw option available in either "A" or "B" type configurations. The choice depends on the injection unit setup and the specific molding requirements. This series is known for its robust performance in medium tonnage applications.
Niigata MDVR/MDVP110X (Vertical)
Vertical molding machines like the MDVR/MDVP110X, rated at 110 tons, commonly use a 40mm diameter screw as standard. This screw supports a shot size of about 3.59 ounces, suitable for vertical injection molding processes that require precise control and compact machine design.
Niigata MD180W
The MD180W is a larger 180-ton horizontal machine that uses a 40mm screw (Type Y). This screw type is designed for specialized precision molding where tight tolerances and consistent shot delivery are critical. The 40mm screw in this model supports complex molding tasks with high repeatability.
Niigata NE85U
Older hydraulic models like the 85-ton NE85U also utilized a 40mm single screw with an L/D (length-to-diameter) ratio of 18. This screw size was standard for its time and remains relevant for maintenance and replacement parts in legacy machines.
Why Choose a 40mm Niigata Screw?
Selecting the correct screw size is essential for maintaining the quality and efficiency of plastic injection molding. The 40mm Niigata screw offers several advantages:
Consistent shot size: Ensures uniform part weight and quality.
Versatility: Fits multiple Niigata models across different tonnages.
Durability: Manufactured to withstand high pressure and temperature.
Precision: Supports tight tolerances for complex parts.
Using the right screw reduces downtime caused by improper fit or wear, improving overall productivity.
