Antistatic ceramic

ADVANCED CERAMICS / By

aNTISTATIC CERAMIC / ESD MATERIAL Antistatic ceramics are specially designed ceramics that dissipate or prevent the build-up of static electricity. They are used to protect sensitive electronic equipment, prevent contamination of sterile environments, and improve safety in a variety of industries. These ceramics often have conductive coatings or additives to achieve their antistatic properties, and their use helps maintain product quality and reliability while reducing the risk of electrostatic discharge-related damage. The ceramic materials developed by LONGYI contain raw materials that reduce resistance, so that the ceramics can have the original mechanical properties, but the electrical properties are changed. Unlike ceramics with a layer of surface coating, the surface will not be changed due to surface friction. Electrical properties, resistance can be maintained at e 106~10 ohms.

Explore the possibilities with us as we make a revolutionary ceramic brazing that brings innovation and durability of ceramic and metal.  Joining Innovation and Durability Ceramics, renowned for their exceptional hardness and resistance to high temperatures, have become staple components in diverse industries. However, bonding ceramics has posed significant challenges. a revolutionary joining process that brings innovation and durability to the table   The process A specialized technique that fuses ceramic components together using a filler material (brazing alloy). This process overcomes the difficulties associated with welding or adhesive bonding of ceramics, providing a robust and hermetic seal between components. By combining the unique properties of ceramics with the bonding strength of brazing, engineers can now unlock new possibilities in their designs. The Crucial Steps The Process involves a series of well-orchestrated steps. Preparing the surface, ensures the ceramic surfaces are free of contaminants, promoting optimal wetting and adhesion of the brazing alloy. Selecting the appropriate brazing alloy, with a lower melting point than the ceramic material is critical. Proper assembly of the components and precise temperature control during heating ensure the brazing alloy melts and flows into the joints effectively.  Careful cooling process, to prevent thermal stresses that could

CERAMIC Metallization

NEWS / By

CERAMIC METALLIZATION Advanced ceramic has distinctive properties, thus it can be joined with metals. Before joining with metal the ceramic needs to be metalized (thin-coating it with metal material which provides an interface for brazing). Then brazed, which creates a vacuum tight, robust joint between ceramic and metal. LONGYI specialize in cutting-edge ceramic metallization solutions that redefine the possibilities of material engineering. With a commitment to innovation, precision, and quality, we bring decades of experience to the table. Our team of experts is dedicated to pushing the boundaries of ceramic technology, providing customized solutions for diverse industries.

5-axis CNC precision machining

Service / By

5-axis CNC precision machining CNC Precision Machining is a machine that uses a digital signal system to control and manufacture. Nowadays, numerical control machines mostly use computers. The most important feature of its equipment is that the data can be entered into different cutting machining system columns before running. When the settings were done, the machine can do machining without intervention. It would follow the process and run different steps to finish the manufacturing. Simply said, it is a machining machine controlled by computer values. Just like a common traditional machine, but applied high technology. The traditional machines need labor and the engineers to overcome the difficulty of the machining. Yet, CNC machining is using CAM applications from the computer and the programming skill. The rest of the steps are relying on the CNC operator’s experience to adjust the parameter and tool correction.  LONGYI operating CNC machining machine follow by the standard organization The method is:1.
