We offer a standardized lineup of widths ranging from the thinnest 6mm to 8mm, 13mm, 20mm, and the thickest 25mm, making it one of the best selections in the industry. As a result, it can accommodate small diameter threads such as 1/8 (1 bu), 1/4 (2 bu), 3/8 (3 bu), 1/2 (4 bu), 3/4 (6 bu), 1 (1 inch), and 2 (2 inches) in pipe threads up to large diameter threads. Seal tape is used on the threaded parts that connect water pipes, air pipes, and hydraulic piping to ensure that the threads fit tightly together. Typically, the connection points of piping are threaded, but without a slight clearance in the threads, they cannot be tightened. Therefore, even if they are engaged, it is impossible to achieve a complete seal. Water, air, or oil flowing through the piping can leak out through these gaps. To prevent such leaks, seal tape is used to stop water, air, and oil leaks at the piping joints. The material of the seal tape is polytetrafluoroethylene (PTFE). This material is a fluoropolymer that excels in heat resistance and chemical resistance. The thin tape-like seal is wound on a reel. Since it is pure PTFE tape, it complies with environmental regulations and can also provide documentation for various regulations.

Typically, when trying to create complex (three-dimensional) shapes, secondary processing (such as machining or wire cutting) is common, but this can lead to clogging (reduction) of the pores, which are a characteristic of porous materials. At Sintering.com, we also attempt to create complex (three-dimensional) shapes without secondary processing. The performance of porous materials greatly depends on the manufacturing process. In many cases, factors such as particle size, pore diameter, density, porosity, and dimensional shape alone are not sufficient to fully realize the performance of porous materials. There are various methods for producing porous materials, and it is essential to choose the appropriate manufacturing process for each specific application.

Products made using the powder metallurgy method (a process of shaping and sintering metal powders to create metal products) are referred to as "sintered metals." Among these, by specializing in sintered metal filters, which are porous metals, we can provide tailored proposals for various applications. Examples of applications include filters (for filtration and separation), silencers (for noise reduction), fluid rectification, liquid absorption, bubbling, and explosion-proof filters (frame arresters), with ongoing development of new applications. Additionally, over 15 types of materials can undergo sintering treatment. There are many types of porous metals, and not only pore diameter but also pore structure affects performance. Our distinguishing feature is that our sintered metal filters, made from metal powders, are all open-pore/continuous-pore (open porous) porous metals. Other types of porous metals include sintered wire mesh, which maintains precision in mesh opening while also providing strength, sponge-like porous metals formed solely from a framework, porous metals with numerous straight holes resembling lotus roots, and foamed metals that contain countless closed pores/independent pores (closed pore) created by adding a foaming agent to molten metal. Each type of porous metal has its advantages and disadvantages, necessitating careful selection of the appropriate porous metal for specific applications.

We have successfully developed a sub-millibubbling nozzle using a fine pore method with sintered metal, where our specifications define sub-millibubbles as having a bubble diameter of 100μm to 999μm. The structure is designed to be very simple, allowing for easy connection, and the piping, pipe shapes, and adjustments can be freely modified. It is also possible to manufacture it as a single piece, making it a very user-friendly nozzle.

Sintered metal filter elements are generally thought to be brazed, but brazing has good wettability and can even cause capillary action, leading to the brazing material penetrating into the interior of the filter. To solve such problems, Sintered.com has developed a technology for welding bronze sintered metal filter elements. With welding, there is no concern about penetration into the interior, and the freedom of processing is also increased.

We have developed an element with finer pores than sintered metals used in filter applications, utilizing the manufacturing technology of sintered metal filter elements. As a result, it has become possible to generate bubbles so fine that they cannot be seen with the naked eye. Since they cannot be confirmed visually, we believe they are microbubbles, but we cannot guarantee this as we have not measured them. The generation method is based on fine pore technology, and the generated fine bubbles (microbubbles) are transparent. Since it is not a pressurized method, there is no cloudiness.

At Sintering.com, we are focusing on micro-bubbling as our top priority and advancing its development. Micro-bubbling does not simply occur by passing through fine pores; rather, if the bubbles only pass through small holes, they do not become microbubbles. On the contrary, this leads to significant pressure loss and a marked decline in performance. Therefore, we are embarking on the development of microbubble generation nozzles using sintered metals, combining this with the metal processing technology that has been the foundation of our company since its inception. Many nozzles currently on the market circulate water (liquid) through piping using pumps, and further high-pressure pumps are employed. This naturally incurs equipment costs and requires installation space. Additionally, piping with water (liquid) increases the risk of leaks, necessitating attention to the surrounding environment. High-pressure pumps can be noisy, and noise control measures may be required in some cases. At Sintering.com, we are developing micro-bubbling based on gas piping and are working on a user-friendly micro-bubbling nozzle that minimizes user equipment by adding an automatic suction function for the solution (liquid) directly to the nozzle, eliminating the need for circulation pumps and high-pressure pumps.

We are manufacturing bubbling and underwater fine bubble generation nozzles. Our bubbling nozzles, made of metal, are strong and have voids (fine pores) that allow gases such as air to pass through, enabling the dissolution of gas in liquids and stirring of liquids, among many other applications. By controlling the bubble diameter, various benefits can be obtained. For example... - Gas dissolution: By reducing the bubble diameter, the volume of the bubbles themselves decreases, improving the reaction speed and quality even with the same flow rate. - Stirring: In the case of stirring, if the bubble diameter is chosen to be too small, the stirring effect will not be achieved. Therefore, it is essential to control the bubble diameter according to the application. To meet such demands, our company aims to control and regulate the bubble diameter. The nozzles we manufacture are completely custom-made, and designs tailored to the equipment conditions and piping are also possible.

This is a bubbling nozzle using laminated sintered metal mesh. By using laminated sintered metal mesh, the pores are made uniform, and additionally, the strength can be ensured due to the laminated sintering process. Since it can be manufactured thinner than sintered metal, it is expected to achieve weight reduction and minimize pressure loss. Shapes that are difficult to process with sintered metal can also be made possible by using laminated sintered metal mesh.

A porous sintered body composed of metal powder (particles) in a three-dimensional structure, with materials including aluminum, copper, stainless steel, titanium, etc. The materials are diverse. By using a porous sintered body, stable air supply is possible, and because the metal powder (particles) are structured in three dimensions, it is possible to achieve high strength despite being relatively lightweight. It can be machined, so a certain level of surface roughness is achievable, but it can also be polished to meet strict surface roughness requirements.

This is a spherical powder!! It is a porous (porous) sintered filter made of ceramics (alumina). Since it uses spheres, the filtration accuracy is uniform and can filter and ventilate without inconsistency. Moreover, the material is a wonderful substance with a purity of 99.99% alumina, so no binder (sintering aid) is used. It is possible to create a cup shape with a lid like the pipe shown in the image, and of course, rod-shaped and pipe-shaped products can also be manufactured. As a filter (for filtration), it has countless applications such as bubbling, adsorption plates, explosion-proof, silencers, etc.

We have made porous (sintered) metal as thin as possible. In the porous (sintered) metal industry, machining has been considered taboo because it causes clogging and prevents the material from functioning as a filter. However, manufacturing with molds has been extremely difficult, and we felt the limitations of porous (sintered) metal. With this technology, the walls of the porous (sintered) metal have been removed, allowing for the production of shapes that were impossible with molds.

Sintered metal filters made from stainless steel (SUS) have a complex structure of pores that form intricate flow paths. Because the material is stainless steel (SUS), it can be welded, has heat resistance that allows it to withstand high temperatures, and exhibits excellent corrosion resistance by forming a transparent oxide film that protects the internal material from corrosion. This has led to its adoption in various applications such as filters, strainers, adsorption stages, explosion-proof filters, and flame arresters. The nominal filtration precision can be selected from 1μm, 2μm, 5μm, 10μm, 20μm, 40μm, 60μm, and 100μm. The nominal filtration precision indicates the size of particles that can be captured, which is different from pore diameter; smaller numbers correspond to finer powders and higher pressure loss. *This is not a guaranteed value.

- By using a layered wire mesh filter, the contact surface is uniform. - Because a layered wire mesh filter is used, there are more options for mesh size and thickness (number of layers), making it adaptable for various applications. - By adding a radius to the corners of the wire mesh, the issue of snagging when materials enter is resolved. - When using a stainless steel (irregular powder) sintered metal filter, the material itself can be sharp, which could pose a problem for soft or thin materials; this issue is resolved. - By applying surface treatment, the slip properties (wear resistance) are significantly improved, and the generation of static electricity can be suppressed. - Since it is adsorbed by air, it can be used with materials that do not stick to magnets (such as plastics, ceramics, carbon, etc.), eliminating the need to create fixtures for chucking.

The sintered metal using SUS304 spherical powder has been completed!! It has a more stable density compared to sintered bodies made from irregular powder, and since there is almost no difference in the shape of the material itself, it can demonstrate stable filtration capabilities. Like our conventional sintered metals, welding is of course possible, but simultaneous sintering is also an option. If you are currently using filters made from SUS irregular powder and often find dissatisfaction with the filter precision, we encourage you to give this a try.

The strongest sintered metal has been completed!! Yes, it's titanium (Ti), which is highly regarded as the strongest among pure metals. Titanium is a well-known high-performance material, and its range of applications is limitless, including the aerospace industry, automotive industry, and industrial components; it is now a "hot" material. However, precisely because it is a "hot" material, it could not be subjected to sintering treatment.

Aluminum (Al) itself is lightweight and has excellent thermal conductivity and electrical conductivity, but by making it a porous (low-density) body, we can increase the surface area and enhance heat dissipation and heat absorption effects. While aluminum-based sponge-like foamed metals are commonly seen, our company's sintered metal with all open pores is unparalleled. By using aluminum-based porous (low-density) materials, we believe we can enhance heat dissipation and absorption effects while achieving weight reduction, thus differentiating ourselves from other companies. The feasibility of manufacturing depends on conditions such as shape, size, and filtration diameter. We can also join aluminum plates with dissimilar metals.
