Temperature control fluid connector for injection molding molds "Nipra"

Easy to install and remove with a hex wrench! Can be installed in a short time, improving work efficiency in setup.

"Nipra" is a temperature control fluid fitting that features our unique technology (internal hexagonal processing). Compared to conventional external hexagonal nipple and joint plugs, it can be easily installed and removed with a hexagonal rod wrench (hexagonal rod spanner). Due to the lack of a hexagonal shape on the outer diameter, it has a small and compact design. Compared to traditional products, it has been developed to be approximately 15% shorter in outer diameter and about 10% shorter in overall length. 【Features】 ■ Easy installation and removal with a hexagonal rod wrench ■ Easy to use in narrow or deep spaces, and for embedding ■ Internal hexagonal processing technology allows for smaller outer dimensions, making it more compact ■ Easy removal of screw remnants in case of male thread breakage ■ Easy management with color coding *For more details, please refer to the PDF document or feel free to contact us.

Quick fluid connector for automobiles

Streamlining piping work in automobile manufacturing!

In the automotive industry, there is a constant demand for the efficiency of production lines and the stabilization of quality. In particular, the connection and disconnection of piping for air, coolant, and hydraulic oil occur frequently, making the reduction of work time and secure connections crucial. Leaks or disconnections at the connection points not only lead to a decline in product quality but also pose significant risks such as safety issues and equipment downtime. Our quick fluid connectors enhance work efficiency and reliability on automotive production lines through features such as: 1. Easy one-touch attachment and detachment 2. Seal structure that suppresses leaks during connection 3. Locking type to prevent accidental disconnection (non-locking options are also available). 【Usage Scenarios】 - Connection/disconnection of air and water piping in automotive manufacturing plants - Piping replacement during equipment maintenance - Frequent piping changes in prototype and experimental lines - Temporary connection applications for jigs and inspection equipment 【Benefits of Implementation】 - Reduction of work time - Improvement of work efficiency - Prevention of troubles caused by leaks - Enhancement of product quality

Fluid fitting (constant oil volume type)

We will propose the optimal fluid coupling based on the starting characteristics of your rotating machinery!

We propose the optimal fluid coupling based on the technology and solid engineering capabilities cultivated from the experience of Voith. ◆ Applications Not only does it absorb the shock load from the driven side during the startup of large inertia machines, but it also absorbs the internal oil. ◆ Features As standard models, we offer fluid couplings with different delay chambers for each size: -T, -TV, -TVV, and -TVVS. This allows for a gentle startup without a sudden increase in torque, even for large inertia rotating machinery. ◆ Built-in Pulley Type We also have models with built-in pulleys, allowing for direct connection from the motor to the fluid coupling to the driven side without the need for installation of a plan block. This design eliminates the need for complicated alignment adjustments and saves space. ◆ Safety Device In addition to the standard fusible plug, a device for monitoring the temperature of the internal oil can also be added. This helps prevent blowouts caused by rising oil temperatures.

[For Hydrogen] Quick Fluid Connectors and Other "Things We Can Do for a Hydrogen Society"

For hydrogen energy filling! Opening up the future with rapid fluid couplings "couplers" and linear compressors.

Towards the realization of a decarbonized society, hydrogen is garnering significant expectations as a next-generation energy source. On the other hand, due to its characteristic of "small molecules that are prone to leakage," infrastructure with high safety and high sealing performance is required. In our publication "What We Can Do for a Hydrogen Society," we introduce products for the safe handling of hydrogen categorized by usage pressure. [The Value Nitto Kohki Provides to the Hydrogen Society] - User-friendly operation with one-touch handling Balances the "speed" and "reliability" required at hydrogen stations and research facilities. - Adaptability to a wide range of applications Supports research and development, hydrogen stations, and industrial hydrogen facilities. - Reliability that supports the future hydrogen infrastructure Designs and quality cultivated through years of fluid technology contribute to stable operations.

Quick Fluid Couplings for Food Factories

Improving hygiene management in food manufacturing! A detachable joint that can be attached and removed with one touch.

In the food industry, hygiene management of the manufacturing process is extremely important. In particular, liquid leaks from pipe connections increase the risk of product contamination and foreign matter intrusion, potentially leading to violations of food safety standards. Additionally, areas that require frequent maintenance and cleaning need to have easily detachable piping. Our quick fluid connectors allow for one-touch attachment and detachment, and they are designed to minimize leaks during connection. This contributes to improved hygiene management in food manufacturing. 【Usage Scenarios】 - Connecting and disconnecting piping in food production lines - Piping systems that require cleaning and sterilization - Areas that undergo frequent maintenance and cleaning 【Benefits of Implementation】 - Reduced risk of product contamination due to liquid leaks - Shortened cleaning and maintenance time - Improved work efficiency - Compliance with food safety standards
