Around us, there is air in a state called "atmospheric pressure," and it can be surprisingly easily utilized by creating a state of vacuum. The state of air with a lower density of air molecules than the atmosphere is called "vacuum," and since the pressure (when considered as gauge pressure) is lower than that of the atmosphere, it is referred to as "negative pressure." The purposes of utilizing vacuum can be broadly divided into two categories: "utilizing pressure difference" and "utilizing vacuum space." 【Two Purposes of Utilizing Vacuum】 ■ Utilizing Pressure Difference - Extracting force from the pressure difference between the atmosphere and vacuum to perform tasks such as workpiece transportation. - Particularly effective for workpieces that are difficult to grasp. ■ Utilizing Vacuum Space - Removing unwanted gas molecules to create a pure space for physical or scientific phenomena to occur. - Preventing troubles caused by substances like oxygen. *For more details, please refer to the PDF document or feel free to contact us.

To switch the directional control valve, an external force is required to change the valve. This includes four types: "manual operation" using hand strength, as well as "mechanical operation," "pneumatic operation," and "electrical operation." Additionally, there are two types: one where the external force directly switches the valve body (direct operation) and another that uses compressed air to switch (indirect operation). The combination of the types of forces and how they are applied is referred to as "operating force," and in solenoid valves, indirect operation (pilot type) is the mainstream. 【Switching Operation】 ■ Manual Operation - Switching by hand strength: Hand valve - Switching by foot strength: Foot valve ■ Mechanical Operation ■ Pneumatic Operation ■ Electrical Operation *For more details, please refer to the PDF document or feel free to contact us.

The "direction control valve" is a valve that controls the flow direction of compressed air (a switching valve). It is capable of applying compressed air to equipment (air supply) or releasing it (exhaust). Its functionality is determined by three properties: the number of piping connection ports, the number of flow states the valve can create, and the operation of the valve body. Please choose according to your purpose. 【Function Details】 ■ Types of Port Numbers - 2 ports - 3 ports - 5 ports (4 ports) ■ Types of Position Numbers - 2 positions - 3 positions *For more details, please refer to the PDF document or feel free to contact us.

The speed control of the cylinder is achieved by adjusting the amount of air flow. The speed controller adjusts one side at a time, creating a bypass circuit for one flow, releasing control, and for this purpose, a check valve is used. The flow that can be adjusted (controlled) in the direction of the speed controller is called "controlled flow," while the flow that cannot be adjusted (controlled) is referred to as "free flow." The cylinder can adjust the speed whether controlling the supply of compressed air (IN side) or controlling the exhaust (OUT side). Controlling the supply is called "meter-in control," and controlling the exhaust is referred to as "meter-out control." Generally, meter-out control is used because it is easier to adjust and stabilizes cylinder operation. While pneumatic systems excel at high speeds, they become difficult to control at low speeds due to their compressibility, leading to a lack of stability. Even in meter-out control, it is challenging to use below 50 mm/sec, and it is typically used at speeds around 50 to 1000 mm/sec. *For more details, please refer to the PDF materials or feel free to contact us.*

Devices that operate and perform work using compressed air are called air actuators, among which the cylinder performs linear motion. There are two types of operation methods: the "double-acting cylinder," which operates in both directions using air, and the "single-acting cylinder," where one side of the operation is performed by a spring. Additionally, the main components of the cylinder include a cylindrical cylinder tube, a piston that moves within the tube, and a piston rod that transmits the piston’s movement to the outside. However, since all these parts are made of metal, they cannot seal compressed air. The piston packing and rod packing move while maintaining a seal, so lubrication is necessary, and this is done with grease during assembly in the case of a non-lubricated cylinder. 【Double-acting Air Cylinder Structure (Excerpt)】 ■ Cushion Valve ■ Head Cover ■ Cylinder Tube ■ Piston ■ Cushion Ring *For more details, please refer to the PDF document or feel free to contact us.

A "pressure reducing valve," also known as a regulator, adjusts the pressure of compressed air to a set pressure lower than that at the inlet, as the name suggests. It stabilizes the pressure supplied to the equipment against fluctuations in the main line pressure, and it is categorized into general fluctuation types and pilot types that excel in high capacity, depending on the operating method. In most pressure reducing valves, if the pressure on the outlet side exceeds the set value, the relief function activates, allowing the outlet air to be discharged and the pressure to return to the set value. 【Features】 ■ Adjusts the pressure of compressed air to a set pressure lower than that at the inlet ■ Stabilizes the pressure supplied to the equipment ■ Allows for the discharge of outlet air to return the pressure to the set value *For more details, please refer to the PDF document or feel free to contact us.

Compressed air is created by compressing the atmosphere on Earth, capturing all the substances contained within it. Additionally, air compressors that produce compressed air use oil for lubrication, similar to a car engine, which means that these altered substances (oil carbon) are also captured. The freshly produced compressed air is quite dirty and contains many impurities, and the process of removing these impurities to create clean air is referred to as "purification." The functions for purifying compressed air include "filtration" performed by air pressure filters, "moisture separation," and "dehumidification" carried out by air dryers. It is important to combine these elements to create an efficient system. **Functions for purifying compressed air:** - Function to remove solid particles and oil: Filtration - Function to remove generated moisture: Moisture separation - Function to remove water vapor: Dehumidification *For more details, please refer to the PDF document or feel free to contact us.*

To effectively utilize air pressure, a line is constructed by combining various equipment, starting from the compression of atmospheric air to the air cylinder that performs work at the final stage. A typical line configuration includes an air compressor, aftercooler, air tank, and many other devices arranged in series. These devices can be categorized into groups based on their functions, such as "compressed air generation," "removal of impurities from compressed air," and "assisting the operation of equipment," and they all influence each other by being arranged in series.

Let me introduce two fundamental laws related to pressure. First, there is "Pascal's Principle," which considers force. Air pressure acts equally in all directions and on all surfaces of a confined container. Therefore, the relationship between pressure, area, and the force generated is always proportional, and in this case, pressure is considered as gauge pressure. Additionally, there is "Boyle's Law," which considers volume. When displaying the volume or flow rate of air (the volume processed per unit time), it is always converted to atmospheric pressure conditions (standard state ANR). This conversion is called atmospheric pressure conversion, and Boyle's Law is utilized. The unit of flow rate used is L/min (ANR). *For more details, please refer to the PDF document or feel free to contact us.*

The state of air compression is not visible to our eyes, but it can be expressed using pressure, and the standard for judging pressure is called "pressure unit." The atmosphere around you actually has pressure as well. Air is compressed by its own weight, generating force, which is referred to as "atmospheric pressure." Pressure readings that do not consider atmospheric pressure are called "gauge pressure," while those that take atmospheric pressure into account are referred to as "absolute pressure." When expressing the volume or amount of air, it is necessary to consider absolute pressure, but in factories, pressure is displayed as gauge pressure. "Gauge pressure" is very convenient for supporting or lifting objects using compressed air, and in factories, pressure is generally considered to be gauge pressure unless otherwise specified. *For more details, please refer to the PDF materials or feel free to contact us.*

Compressed air is produced by an air compressor. This is a machine that sucks in atmospheric air, compresses it, and creates compressed air. The compressed air flows through pipes and tubes to the work location where it is used, and then it is released back into the atmosphere, returning to its original state. Therefore, air pressure systems do not deplete air as a resource. Of course, even when compressed, the properties of the air itself do not change, making it a safe energy source that is free from pollution. Additionally, compressed air has good energy storage capabilities, as it can be contained in a vessel and maintained as potential energy. Thus, air pressure has many excellent features as an energy source, and it is expected to expand its range of applications in the future. *For more details, please refer to the PDF document or feel free to contact us.*

Air pressure is used in various ways not only within factories but also in our everyday lives. For example, it is utilized for force in tires and air mattresses, while camera blowers use it for airflow. Additionally, air cylinders are employed in the opening and closing of doors, combining air and flow to utilize "movement." An air cylinder contains a "piston" that operates under the action of compressed air within a cylindrical container, and the movement is transferred externally through a "rod" fixed to the piston. This is an air cylinder, a device that plays a significant role when utilizing compressed air for work. In this way, air pressure is used extensively in various production processes in factories for automation and labor-saving purposes, performing tasks that replace human labor. *For more details, please refer to the PDF materials or feel free to contact us.

When air is allowed to flow from a high-pressure state to a low-pressure state, it bursts out vigorously. And by stopping when the pressures equalize, a flow of air is generated. Conversely, if there is a flow of air, there must be a difference in pressure. You can check the details using diagrams in the PDF download. Please take a look. *For more information, please refer to the PDF materials or feel free to contact us.*

The gas molecules that make up air move freely, so when considering a container, they collide with the walls of the container at a constant state, generating force. The walls receive a constant force from the air, and this force is captured as a numerical value called "pressure." If the density of the gas molecules changes due to compression, the state of the collisions with the walls changes, and the pressure varies, becoming higher or lower. When assessing the state of the air, it is expressed in terms of pressure levels. High pressure indicates a strong state of compression with a high density of molecules, suggesting that the air is generating a significant force. *For more details, please refer to the PDF document or feel free to contact us.*

The Earth we live on is surrounded by a layer of air. This is called the atmosphere, and it is thought that "the Earth's gravity holds the substance of air." However, air is such a familiar presence that we often do not think about it. In reality, air is a mixture of various gases, and these gas molecules move freely. When the number of gas molecules is kept constant and the volume of air is changed, the density of the molecules changes. Because air is compressible, air that is in a compressed state compared to the atmosphere is referred to as "compressed air." *For more details, please refer to the PDF document or feel free to contact us.*

A "dial gauge" typically has a type that measures 0.01mm, where one full rotation of the long needle corresponds to 1mm, with a maximum measurement of about 10mm. The 0.001mm type can measure up to 1mm, with one full rotation of the long needle corresponding to 0.2mm. The dial gauge is fixed to a stand with a magnetic base, which is secured to a reference surface. The object to be measured is placed under the gauge for comparative measurement against a block gauge. In our company, we fix a magnetic base to the head mounting part and use it to achieve high precision parallelism of the extraction machine relative to the molding machine. *For more details, please refer to the PDF document or feel free to contact us.

A "height gauge" typically has a minimum measurement scale of 0.01mm or 0.02mm and is used to measure the height from a reference surface, such as a standard plate. It uses a stable measuring surface as the reference and measures the height of the target from that reference surface. The scale reading is the same as that of a caliper. Additionally, similar measurements are taken 2 to 3 times to confirm that the measurement values are consistent. *For more details, please refer to the PDF document or feel free to contact us.*

A "caliper" is used for measuring parts during assembly and for measuring dimensions during processing. It is used to measure the outer diameter, inner diameter, depth, and step differences of the object. For outer diameter measurement, read the smallest scale when measuring the outer side of the object, and for inner diameter measurement, read the largest scale when measuring the inner side of the object. Additionally, for depth measurement, hold the caliper vertically against the object and read the scale at the deepest point. *For more details, please refer to the PDF document or feel free to contact us.
