Daiko Tokyo Branch Processing Example No. 20 Gaskets and Industrial Products!

Introducing examples of processing gaskets, packing, and industrial products! We process them using various machines, including water jets (high-pressure processing machines)!

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We use various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. We processed a 1-ton three-sheet. While equivalent processing is possible with water jet cutting, the plotter can process while vacuuming (keeping the material flat). Unlike water jets, it does not get wet. For these two reasons, processing with a plotter is suitable.

Daiko Tokyo Branch Processing Example No. 50 Gaskets and Industrial Products!

Introducing examples of processing gaskets, packing, and industrial products! We process them using various machines, including water jets (high-pressure processing machines)!

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We utilize various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. We performed adhesive processing on NBR rubber with a diameter of 2325mm. While 2325mm is a large diameter, we can perform segmented processing with the water jet, allowing for production without any deviation in hole pitch. This time, we processed it into four segments, but we can accommodate the desired number of segments as well.

What is the difference between O-rings and gaskets/packings?

We will also explain the details of each, such as how they are used and their shapes!

O-rings, gaskets, and packing are all types of seals that prevent the leakage of liquids and gases, but they differ in their usage and shape. An O-ring is a ring-shaped seal with a cross-section that is O-shaped, as its name suggests. It utilizes the elasticity of the material to be compressed when fitted into a groove, thereby achieving a sealing effect. When used for motion, it is a type of packing, and when used for fixing, it is a type of gasket. Due to its simple structure, low cost, and high sealing performance in a compact space, it is used in a wide range of fields, including automobiles, hydraulic and pneumatic equipment, and home appliances. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.

Case Study on Measures for Leakage Prevention in PVC Piping

We will introduce "D Packing," which contributes to reducing water leakage risks and improving construction quality!

Are there any issues regarding leak prevention in PVC piping? "When I tried to stop the leak by tightening it strongly, the flange broke." "The tightening is inconsistent among workers, leading to unstable construction quality." "I thought I had tightened it properly, but it's still leaking." Unlike metal, PVC piping cannot be tightened with excessive force. Therefore, a delicate balance is required with standard sheet gaskets to ensure that they "do not leak but also do not break from over-tightening," which always carries the risk of leakage. *For more details, you can view the related links. Please feel free to contact us for more information.

What is the difference between a gasket and a packing?

We will also introduce the criteria that are clearly defined depending on the place of use!

Gaskets and packing are both sealing materials that prevent the leakage of liquids and gases, but they are clearly distinguished by the "movement" of the places where they are used. In simple terms, gaskets are used in stationary places, while packing is used in moving places. A gasket is a sealing material used in stationary parts. When fixing parts together with bolts or similar fasteners, it is inserted between them to eliminate gaps, preventing internal fluids from leaking and external foreign substances from entering. *For more detailed information, please refer to the related links. Feel free to contact us for further inquiries.*

What is the RCF (Refractory Ceramic Fiber) regulation?

We will also introduce what our company has implemented and the products in response to the RCF regulations!

As of November 1, 2015, the amendment to the Labor Safety and Health Act has made Refractory Ceramic Fibers (RCF) subject to regulations aimed at preventing health hazards to workers. With this amendment, RCF has been designated as a substance that requires labeling and classified as a Category 2 substance under the management of specific chemical substances, thus subjecting it to stricter preventive regulations. In response to this RCF regulation, Daiko has completely switched from traditional ceramic cloth to a safer, bio-soluble ceramic cloth. *For more detailed information, please refer to the related links. For further inquiries, feel free to contact us.*
