Solving Social Issues Using Our Products

Improving Productivity

Against a backdrop of labor shortages and other social issues, manufacturers are pursuing automation and streamlining as a means to increase productivity. KEYENCE is helping to reduce production time and improve throughput by proposing products and applications that lead to improved manufacturing efficiency.

  • This wide range of tools makes it possible to perform up to 100 simultaneous measurements.

The optical-axis alignment function allows for easy installation.

Enhancing Quality

As the sophistication and miniaturization of products increase thanks to technological innovation, advancements in manufacturing must keep pace. Consumers demand ever higher quality year after year, and a defective product can severely harm a company’s brand image and reduce profitability. KEYENCE helps solve the problems these advanced manufacturing sites must grapple with.

Ensuring Safety in the Workplace

KEYENCE creates products that help ensure safety at manufacturing sites. Specifically, we are promoting the improvement of on-site safety by developing safety equipment that ensures that workers are safe from hazardous elements such as machinery and robots while maintaining a high level of productivity.

Improving the Working Environment

Safety measures are required in Japan when handling ink and solvents that use organic solvents and alcohols. A risk assessment must be performed to check the harmfulness of ink and solvents when using an industrial inkjet printer. KEYENCE inkjet printers are equipped with various features to prevent health risks.

In the past, separate equipment was required to safely perform maintenance.

Daily maintenance is required to use an inkjet printer. Businesses must research these measures based on the results of the risk assessment.

General Principles of Containment

Examples of measures taken to prevent the release of chemical substances are shown.


Workers must use this box, which provides air intake and exhaust to reduce exposure to chemical substances.

Respiratory Protective Gear

Workers are recommended to use a respiratory mask to prevent inhalation of chemical substances.

Occupational Health Protective Gear

Workers are recommended to wear protective glasses and solvent-resistant gloves to protect the skin and eyes.

Anyone can perform maintenance of the MK-U Series safely.

The MK-U Series has a new design to prevent exposure to and inhalation of ink and solvent. No special measures or additional cost is required unlike with conventional inkjet printers.

Equipped with auto-shower cleaning function

The MK-U Series has a new design to prevent exposure to and inhalation of ink and solvent. No special measures or additional cost is required unlike with conventional inkjet printers.

Direct bottle drainage

Simply attach the bottle and cap securely to prevent leakage. This eliminates the need to worry about exposure and inhalation during drainage.

Ink and solvent cartridges

There is no need to pour ink or solvent into a tank, thereby eliminating the risk of volatilization or spills. Replacing empty cartridges is also simple with one-touch removal.

Easy replacement

Simply follow the instructions to replace the filter without worries about internal ink spills. No tools are required to replace the filter.

Helping Reduce Energy and Resource Consumption in Factories

Environmental issues such as climate change are an urgent problem on a global scale, and year after year the need for measures to conserve energy and resources in factories is growing. KEYENCE, through our products, supports our customers’ initiatives to conserve energy and resources.

Reducing Environmental Impact at Customer Locations

Various liquids and gases—including cutting water, cutting oil, coolant, hydraulic oil, argon gas for welding, air for air blow, and paint for coating—are used during production at factories. These fluids are conveyed through facilities using pumps, fans, and other equipment. The pumps, fans, and compressors that move these fluids use large amounts of electricity while running. Flow sensors play an important role in energy conservation by managing and recording the usage of fluids, so wasteful conveyance is kept to a minimum.

Saving Energy with Flow Sensors

In factories, compressed air is used for air tools, presses, spray guns, and air cylinders that power robots and machine tools. Compressors are used to produce this compressed air, which consume a large amount of electricity. These compressors, which are so important to the operation of factories, tend to leak large amounts of air, which is a major source of losses. Accurately managing the flow of compressed air is very important to prevent losses and save energy. Doing this allows for optimization of the amount of electricity used by the compressor, leading to reduced energy consumption.
Flow sensors allow for monitoring and visualization of the flow of compressed air. This means that air leaks can be detected, making them a highly effective and important part of energy-saving measures, such as lowering the pressure according to usage, using an inverter, or limiting the number of units.

Usage example: Managing use of compressed air

By determining the flow rate from the receiver tank, the amount of compressed air used throughout the factory can be measured.

Saving Energy with Pressure Sensors

Many machine tools use hydraulic cylinders and hydraulic valves. Oil is used not just to run machines, but also for cleaning and cooling. Conventional tools frequently suffer from insufficient hydraulic management of these processes. When considering energy conservation, it is very important to manage hydraulic pressure and keep unnecessary pressure application to a minimum. The most effective way to accomplish hydraulic management is by using oil pressure sensors. By managing oil pressure at all times, changes can be monitored, and deterioration and leaks of hydraulic oil can be detected easily.

Energy-Saving Measures Based on Visualization of Management Values

To implement energy-saving measures in the manufacturing industry, data must be acquired with devices like flow and pressure sensors, which can then be used to visualize how much energy is being used, where it is used, and in what process. The PDCA (Plan-Do-Check-Act) cycle is used to study energy-saving measures based on an understanding of energy use, and to repeat the process of implementation and improvement to continuously improve practical energy-saving measures.
