Key technical specifications include:


  • Thread Pitch: M18 x 2.5 Left Hand

  • Check Ring Outer Diameter: 1.375" to 1.376"

  • Overall Length: About 3.83 inches

  • Nose Angle: 35 degrees per side


These precise dimensions allow the tip assembly to fit perfectly into compatible Niigata machines, ensuring optimal performance and longevity.


Which Machines Use the 35mm Niigata Tip Assembly?


This tip assembly is commonly used in mid-range Niigata injection molding machines, especially those with clamping forces between 55 and 110 tons. It fits several Niigata machine series, including:


  • MD-S8000 Series: The latest 8th generation all-electric machines known for high precision and energy efficiency.

  • MD-S Series (MD-SIII, MD-SIV): Older generations of all-electric machines that still deliver reliable performance.

  • MDV / MDVR Series: Vertical and rotary table machines often used for insert molding and overmolding applications.

  • MZ Series: Electric machines that combine servo-hydraulics for enhanced control and speed.


These machines benefit from the 35mm tip assembly’s design, which supports consistent plasticizing and injection cycles.


Why Choose the 35mm Niigata Tip Assembly?


Selecting the right screw tip assembly affects the quality of molded parts and the machine’s operational efficiency. The 35mm Niigata tip assembly offers several advantages:


  • Precision Fit: The exact thread pitch and check ring diameter ensure a secure fit, reducing wear and tear.

  • Optimized Melting: The 35-degree nose angle improves plastic flow and melting, which leads to better part quality.

  • Durability: Made from high-quality tool steels, these tips withstand high temperatures and pressures.

  • Versatility: Compatible with multiple Niigata machine series, making it a flexible choice for various production needs.


Using the correct tip assembly reduces the risk of defects like incomplete melting or poor mixing, which can cause scrap or rework.


Where to Find Replacement 35mm Niigata Tip Assemblies


Reliable suppliers offer OEM-compatible and high-wear replacement assemblies to keep your machines running smoothly. Two key suppliers include:


  • Complete Plastics: Offers standard and high-wear replacement assemblies tailored for Niigata machines. They provide expert support and fast shipping.
