Copper has high thermal conductivity and is used in cooking utensils, thermal conduction components, and heat exchangers. It also has excellent castability and workability, and its beautiful surface appearance makes it a material used for art and decorative items. This is a booklet that clearly explains the appropriate joining method for copper products, "Brazing of Copper Components." Currently, we are offering a free basic knowledge booklet to the first 100 applicants. 【Overview】 ■ Characteristics of Copper ■ Main pure copper materials used as base materials and their characteristics ■ Other copper alloys ■ Classification of copper joining methods ■ Main brazing materials and temperature ranges used for brazing copper components ■ List of main silver brazing materials ■ List of main phosphorus copper brazing materials ■ List of main nickel brazing materials ■ Considerations for selecting brazing methods for each brazing material ■ About Shinwa Joytec Center Co., Ltd. *For more details, please check the information through [Request for Materials] or [Catalog Download].

In the upcoming 5G era, a challenge is how to suppress the "heat generation" associated with the high-speed processing of machines. To address this, the complexity of heat exchangers and various components is being emphasized, and the technology of "brazing" will play a significant role in these areas. We are currently offering a technical document that clearly explains the appropriate joining method "brazing" for products that require compactness and high performance. [Overview of Contents] ◆ Basic principles of brazing ◆ Detailed explanation of brazing - Reasons why a strong joint can be achieved when "brazing" fills the joint gap - Capillary phenomenon and optimal gap for brazing - Wetting of the brazing material due to the reducing action of the base material and brazing filler - Four major elements of brazing ◆ Introduction to main brazing materials ◆ Vacuum brazing - Advantages of vacuum brazing - Disadvantages of vacuum brazing - Vacuum brazing process - Heating conditions for vacuum brazing - Guide for selecting brazing materials based on base material combinations *For more details, please check the information through [Request for Materials] or [PDF Download].

With the development of communication networks and the advancement of devices, the challenge is how to suppress the "heat generation" that occurs during high-speed processing. To address this, the "complexity" of heat exchangers and various components is required, and the technology of "brazing" becomes a joining technique that plays an active role in such areas. We are currently offering a technical document that clearly explains the appropriate joining method "brazing" for products that require compactness and high performance. [Overview of Contents] ◆ Basic principles of brazing ◆ Detailed explanation of brazing - The reason why strong joints can be made by the flow of "brazing material" into the joint gap - Capillary phenomenon and optimal gap for brazed joints - Wetting of the brazing material due to the reducing action of the base material and brazing material - The four major elements of brazing ◆ Introduction to main brazing materials ◆ Vacuum brazing - Advantages of vacuum brazing - Disadvantages of vacuum brazing - Vacuum brazing process - Heating conditions for vacuum brazing - Guide for selecting brazing materials based on base material combinations *For more details, please check the information through [Request for Materials] or [PDF Download].

We would like to introduce our "Large Batch Aluminum Brazing Furnace." In addition to being capable of handling large products, it features excellent heat uniformity and brazing temperature control suitable for aluminum brazing. At the Joytech Center, which is centered around the "joining technology" that is the foundation of Shinwa, we support everything from the manufacturing of brazing materials and technology development related to brazing to prototype production and contract processing, delivering "joy" to society through our metal joining technology. 【Specifications】 ■ Temperature: MAX 650℃ ■ Effective dimensions: W1600×L2300×H500mm ■ Temperature control: 6-zone PID control ■ Nitrogen atmosphere ■ Two-chamber furnace ■ Oxygen concentration meter *For more details, please download the PDF or feel free to contact us.

In aluminum heat exchangers for air conditioners, the increase in size and complexity of parts makes uniform heating difficult, leading to issues such as temperature variations and defects due to oxidation. As a result, it is challenging to ensure stable quality from prototype to mass production, which can also impact production efficiency and delivery times. To address the need to solve these problems, Shinwa's Joytech Center has newly introduced a large batch aluminum brazing furnace. With a spacious furnace that can provide stable heating for large parts at once, precise temperature management through 6-zone PID control, and oxidation prevention in a nitrogen atmosphere, we achieve stable, high-quality brazing from prototype to mass production. This setup can also be utilized for complex condition settings and process verification, significantly contributing to the development and production efficiency improvement of heat exchangers for air conditioners. 【Specifications】 ■ Temperature: MAX 650℃ ■ Effective dimensions: W1600×L2300×H500mm ■ Temperature control: 6-zone PID control ■ Nitrogen atmosphere ■ Two-chamber furnace ■ Oxygen concentration meter *For more details, please download the PDF or feel free to contact us.
