Diffusion bonding for joining metals! There are also examples of its application in fuel cell separators with complex flow path patterns and filters for food manufacturing, which cannot be achieved through cutting processes!

Layered diffusion bonding is a method of joining layered materials by applying pressure and heat in a vacuum furnace. Due to the small deformation on the order of micrometers, it is suitable for machining parts with fine flow paths and complex shapes. ■ Application examples for fuel cell separators - Capable of accommodating complex flow path patterns that cannot be achieved through cutting processes - Stable quality due to the simultaneous bonding of multiple products - Complex part shapes can be created through layering - Strong against changes and deformation of parts as no adhesives are used - Simplification of the manufacturing line and reduction of time - Achieves flow paths without gaps at the bonding surfaces, resulting in no losses ■ Application examples for filters used in food manufacturing - Material: SUS316 - Dimensions: φ25×t1.5 - Layer composition: 50μm×30 layers - Mesh dimensions: φ75μm (inner) to φ100μm (outer) taper * For more details, please refer to the PDF document or feel free to contact us.

High-cycle mold "Built-in cooling water channels for uniform cooling of the molding surface" produced using diffusion bonding technology!

Due to the limitations of conventional molds, it was impossible to arrange flow paths evenly on the molding surface, as only linear flow paths could be processed. By utilizing Yamatec's diffusion bonding technology, it becomes possible to process the mold in a sliced plate form. By stacking the components processed from each plate and performing diffusion bonding, it has become possible to design curved flow paths that are arranged evenly on the molding surface. 【Features】 ■ Uniform rapid cooling without product inconsistencies ■ Significant reduction in cooling time ■ Improved quality in product appearance, precision, strength, etc. ■ Increased production efficiency and reduced production costs *For more details, please refer to the PDF document or feel free to contact us.

Method for manufacturing bottom bushes of direct blow molds or neck bushes of two-axis stretch blow molds! Joining technology that does not require welding or adhesion: [Diffusion Bonding].

We will introduce examples of production using diffusion bonding, including complex structure jigs, hollow heat sinks, and metal filtration filters. With diffusion bonding, it is possible to create molds with flow paths that could not be made using traditional mold manufacturing methods such as "cutting" or "casting." In particular, by incorporating precise flow paths within the mold that maximize cooling efficiency, production efficiency can be dramatically improved, resulting in a significant reduction in manufacturing costs. By stacking and bonding laminated materials, we can provide innovative molds that are more rational and have higher production efficiency without being constrained by manufacturing process limitations. 【Features】 ■ Creation of molds with cooling flow paths is possible using diffusion bonding ■ Significant reduction in manufacturing costs is achievable ■ Provision of more rational and highly efficient innovative molds ■ Capable of handling large sizes up to 1000 mm x 1000 mm *For more details, please refer to the PDF document or feel free to contact us.

That concern might be solved with 【diffusion bonding (thermal pressing)】! Many successful examples! Fine channels within molds are also possible! Titanium, nickel, stainless steel, and more are acceptable!

A joining technology that does not require welding or adhesive, known as diffusion bonding (thermal pressing), is a method of joining various metals by heating and applying pressure without the use of adhesives (filler materials). It offers advantages such as enabling internal flow paths that are impossible with metal processing like cutting, and it produces almost no deformation, distortion, or burrs. "Could your concerns be resolved with diffusion bonding (thermal pressing)?" - I want to create complex jigs with no burrs at all. - Can you handle even small lot sizes? - I want to prototype and then mass-produce, but the delivery time is short. - I want to join aluminum alloys. - I have a rough design concept but want to develop it while verifying prototype data. - I want to place a consistent order for everything from material procurement to processing, joining, and inspection. - If the components of filler materials or insert metals have an impact, it can cause issues in the cleaning process. - I want to challenge further miniaturization of microchannel heat exchangers for hydrogen stations. *For more details, please refer to the PDF document or feel free to contact us.*

At construction sites, temporary parking lots may be established for workers and construction-related vehicles. On unpaved ground, mud and ruts can easily occur due to rain, which may hinder vehicle access. Hyper CLT mats are civil engineering materials that utilize wood CLT. By laying them in temporary parking lots, a suitable environment for vehicle passage and parking can be created while protecting the ground. They can be laid only in the necessary areas, and after the construction is completed, they can be removed and repurposed for temporary roads or access routes. The 5×10 panels weigh approximately 230 kg, and the 5×20 panels weigh about 460 kg, making them lightweight and easy to install and remove even with small machinery, allowing for changes in parking space. Additionally, they offer benefits unique to wood, such as glare reduction, noise reduction, and CO2 fixation. They are registered as a technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS as "TH-250021-A," and can be utilized for the development of temporary parking lots and innovative public works.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can change the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.
