What Makes the 36mm Nissei Barrel Special


The 36mm diameter is a popular choice for injection molding barrels because it balances material throughput and precision. The overall length of 30.59 inches is tailored to fit specific injection units, ensuring optimal melting and injection performance.


This barrel size is often found in:


  • PS Series: Older hydraulic machines like the PS40 and PS60 use 36mm screws as standard or optional parts.

  • FN Series: Hybrid models such as the FN1000-12A frequently use 36mm barrels.

  • NEX Series: All-electric machines like the NEX30, NEX50, and NEX80 often feature 36mm barrels as either standard or high-capacity options.

  • NP/NS Series: Legacy machines in the 40–80 ton range also use this barrel diameter for general molding tasks.


The 30.59-inch length corresponds to the injection unit size, which varies between models. This length ensures the barrel fits precisely, maintaining the machine's performance and reliability.


Compatibility with Nissei Machine Models


Choosing the right barrel depends on the injection molding machine model and its injection unit. The 36mm barrel with a 30.59" overall length fits well with several Nissei models:


PS Series Machines


  • PS40 and PS60: These older hydraulic machines often use 36mm screws. The barrel length matches the injection unit size, supporting consistent material flow and injection pressure.

  • These machines benefit from the 36mm barrel's balance of throughput and control, making it suitable for a wide range of molding applications.


FN Series Machines


  • FN1000-12A and FN2000: Hybrid machines that combine hydraulic and electric features.

  • The 36mm barrel fits the 12A injection unit size, which is common in these models.

  • This barrel size supports efficient melting and injection, improving cycle times and part quality.


NEX Series Machines


  • NEX30, NEX50, NEX80: All-electric machines designed for precision and energy efficiency.

  • The 36mm barrel is often the high-capacity option for 30–50 ton machines and standard for 80-ton machines.

  • Its length and diameter support consistent shot size and melt quality, essential for electric injection units.


NP/NS Series Machines


  • Older legacy machines in the 40–80 ton range.

  • These machines use the 36mm barrel for general-purpose molding, providing reliable performance across various materials.


Why Choose a 36mm Nissei Barrel with 30.59" Length?


Selecting the correct barrel size and length impacts molding quality, cycle time, and machine longevity. Here are key reasons to choose this specific barrel:


  • Precision Fit: The 30.59" length matches injection units designed for this size, preventing leaks and wear.

  • Material Efficiency: The 36mm diameter supports a good balance between throughput and melt homogeneity.

  • Versatility: Compatible with multiple Nissei models across hydraulic, hybrid, and electric series.

  • Durability: Nissei barrels are made with high-quality materials to withstand wear and corrosion.

  • Improved Cycle Times: Proper barrel size helps maintain consistent melt temperature and pressure, reducing cycle times.
