770-417-6983 / www.completeplastics.com. A 35mm Niigata screw plays a crucial role in many plastic injection molding machines, especially those from Niigata’s well-known series. If you operate or maintain Niigata injection molding equipment, understanding the applications and compatibility of this screw size can help you optimize machine performance and maintain precise shot control. This post explores the machines that use the 35mm Niigata screw, its key features, and how to order replacements or upgrades.
Which Niigata Machines Use the 35mm Screw?
The 35mm Niigata screw is a standard component in several Niigata plastic injection molding machine series. These machines vary in tonnage and configuration, but the 35mm screw fits specific models designed for mid-range production needs.
Niigata MD-S8000 Series (All-Electric)
This is Niigata’s 8th-generation all-electric series. The 35mm screw is commonly found in mid-range tonnage models such as the MD110-S8000 (110-ton) and the 85-ton variants. These machines benefit from the screw’s ability to deliver precise shot sizes and consistent melt quality.
Niigata MD-S6000 & MD-S7000 Series
Older generations of all-electric horizontal machines in these series often came with the 35mm screw as either a standard or optional feature. These machines typically cover tonnage from 55 to 110 tons, making the 35mm screw a versatile choice for various molding applications.
Niigata MD-V & MDVR Series (Vertical Machines)
Certain vertical rotary models, especially those designed for insert molding, can be equipped or retrofitted with a 35mm injection screw. This allows for flexibility in shot volume depending on the molding requirements.
Key Features of the 35mm Niigata Screw
The 35mm Niigata screw is not just a simple replacement part. It is engineered to maintain high precision and durability in demanding injection molding environments.
Overall Length
The screw measures approximately 32.28 inches in length, providing the necessary reach and compression for effective plasticizing and injection.
Shot Size Flexibility
In machines like the MD110-S8000, the 35mm screw is part of a "Shot Maker" system. This system allows operators to adjust shot sizes between roughly 2.75 to 6.53 ounces by changing the screw and barrel configuration. This flexibility supports a wide range of product sizes and cycle times.
Screw Tip Assemblies
The screw tip assembly is a critical component that ensures consistent melt flow and shot control. The 35mm screw tip assembly is a standard replacement part compatible across multiple Niigata machine generations, helping maintain machine accuracy and prolong service life.
Why Choose a 35mm Niigata Screw?
Selecting the right screw size impacts the quality and efficiency of your injection molding process. The 35mm Niigata screw offers several advantages:
Precision Control
Its design supports accurate shot volume control, reducing material waste and improving product consistency.
Versatility
Compatible with multiple Niigata series, it suits a variety of molding tasks from small to medium shot sizes.
Durability
Manufactured to withstand high temperatures and pressures, it ensures long-term reliability in demanding production environments.
