We are processing materials using various machines, including one of the largest water jets in Japan (processing range 4000W x 5800L). We would like you to visit our factory to see how packing and gaskets are made, the scale of our factory, and what materials can be processed. ★ We are also conducting test processing, so please feel free to contact us. We hope to provide information that can be of help to our customers.

At Daiko, we conduct test processing using one of Japan's largest water jets (processing range 4000W x 5800L). Various industrial products such as gaskets and packing (non-asbestos joint sheets, rubber, sponge, and resin) can be processed. "Features of Water Jet" 1. No thermal impact... Since tools like blades and drills do not touch the material, there is no heat generation. 2. Processing range... The processing range of 4000W x 5800L is one of the largest in the country. 3. No molds required... Unlike press processing, which requires molds and dies, water jet processing uses high-pressure water, so molds are not necessary. 4. Small lots... Since molds are not required, we can accommodate small lots without incurring high costs. "Water Jet Processing is Recommended for Those Who" 1. Cannot find processing services for large-diameter materials. 2. Want to test process using new materials. 3. Are troubled by changes or discoloration due to heat generation during processing. We hope to provide information that can be of help to our customers.

At Daiko Co., Ltd., we are offering a gasket fluid compatibility chart! Are you having trouble selecting gaskets and packing? With the transition from asbestos to non-asbestos, it has become difficult to choose the right type. We have compiled a list of compatible products from various manufacturers for your reference, and we hope you find it useful for your selection process. Please note that this is a guideline, and the suitable products may vary depending on the usage conditions, so feel free to contact us for more details.

This is a compatibility chart for rubber fluids. It lists the compatibility of various types of rubber, including natural rubber, neoprene rubber, NBR rubber, EPDM rubber, Viton rubber, and silicone rubber, with different fluids. While it is only a guideline, it serves as an example of systematic categorization. Please use it for selection purposes.

Nichias: This is a comparison table for fluid compatibility of Vulcargas gaskets. Asbestos joint sheets have versatile properties that allow them to cover a wide range of practical applications due to their excellent heat resistance and pressure resistance. However, as the transition away from asbestos progresses, a certain degree of categorization for usage applications will be necessary. The alternative flow shown below is merely a guideline, but it serves as an example of systematic categorization. Please use it for selection purposes.

"Features of Water Jet" A water jet is a water pressure cutting machine that uses high-pressure water as the cutting source. It can process various industrial products such as gaskets and packing (non-asbestos joint sheets, rubber, sponge, and resin). 1. No thermal effects... Since tools like blades and drills do not touch the material, there is no heat generation. 2. Processing range... The processing range is 4000W x 5800L, one of the largest in the country. 3. No molds required... Unlike press processing, which requires molds and dies, water jet processing does not need molds as it uses high-pressure water. 4. Small lot sizes... Since molds are not required, small lot sizes can be handled without incurring high costs. "Water jet processing is recommended for the following people" 1. Those who cannot find processing options for large-diameter products. 2. Those who want to test process using new materials. 3. Those who are troubled by changes or discoloration due to heat generation during processing. We hope to provide information that can be of help to our customers.

〇 Processing Features - This machine tool was developed for applications that perform machining impossible with conventional blades or cutting tools by utilizing laser light for cutting and machining. Since it processes without contact, the material does not deform due to stress or pressure during machining. By linking with image processing software and directly transferring data to the machining machine, the process of creating molds or casts, which was previously necessary, is eliminated, allowing for a variety of machining options. 〇 Processing Range - 1200W x 2400L 〇 Product Examples - Metal products (gaskets, packing) - Resin products (acrylic, etc.) - Wood products *Various material test machining is possible.
