◆Yoshida SKT Co., Ltd.◆ NEW "What types of materials are used for molds? An introduction to surface treatments as well." has been published.

We will introduce the main materials used for molds, as well as surface treatments and case studies that can solve molding troubles.

There are various types of materials used for molds, but generally, the following are common: - Tool Steel: A type of steel that excels in wear resistance, heat resistance, and strength, used for the main parts of molds and cutting edges. - Cold Work Tool Steel: Known for its high hardness and dimensional stability, used for small parts of molds and complex-shaped components. - Hot Work Tool Steel: Maintains strength and dimensional stability even at high temperatures, used for large mold components and parts used under high temperatures. - Aluminum Alloy: A lightweight and highly workable material used for molds in low-pressure casting and high-pressure casting. - Copper Alloy: Possesses high electrical and thermal conductivity, used for molds in plastic injection molding and die casting. - Ceramics: A material that excels in heat resistance and wear resistance, used for molds that operate at high temperatures and for precision molding. As such, various materials are used for molds depending on their applications. Choosing the appropriate material is essential, but selecting the right surface treatment is also important for the mold's lifespan and product quality.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is kept to a minimum. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
