As a manufacturer of vacuum pump accessories, BTLAS specializes in the research and production of vacuum pump filters, offering真空 filtration solutions. We continue to share valuable insights with you, this time focusing on the vacuum requirements for vacuum furnaces. Products produced by vacuum furnaces are ubiquitous in our daily lives, ranging from certain automotive components, among others. Vacuum furnaces come in various types, each catering to different processes such as brazing, sintering, hardening, nitriding, crystal growth, as well as melting and casting equipment, all of which necessitate a vacuum environment.

Let’s delve into the specific requirements for vacuum equipment in these processes. For sintering, the vacuum equipment must be robust and dust-resistant, with specified pressure ranges for operation. In brazing, besides durability, the equipment must have high pumping speed and low-end pressure capabilities. Lastly, for hardening, the vacuum equipment is required to be highly reliable, capable of rapid evacuation and again, operate within designated pressure parameters.

BTLAS, as a manufacturer of vacuum pump accessories, further explains how vacuum furnaces operate. Within the vacuum furnace, the workpiece is heated while the vacuum pump creates a low-oxygen environment, preventing oxidation of the workpiece. In vacuum sintering, the vacuum improves surface quality and facilitates debinding processes. In vacuum brazing, the vacuum induces degassing, enhancing the hardness and quality of the welds. For vacuum hardening, the vacuum prevents deformation, thereby improving surface quality as well. An added advantage of this process is the ability to perform nitriding directly after hardening. It is crucial to reach the prescribed process pressure within a specified timeframe for each process. Short evacuation times are more cost-effective and, importantly, the evacuation process plays a vital role in removing unwanted substances like hydrogen.

Vacuum pump accessories significantly contribute to enhancing pump performance and extending pump lifespan. BTLAS, with over two decades of experience in the vacuum filtration field, places great emphasis on product quality and research, consistently developing competitive products that cater to the evolving needs of the industry.
