ZHUODA research and development pit type vacuum gas nitriding furnaces for nitriding yields uniform,precision nitrided components in reduced cycle times with controlled white layer to customer specifications. We guarantee their long-lasting work and reliability, which leads directly to your profit and satisfaction. The furnace passed the ISO9001: 2008 quality certification.
The pit type vacuum gas nitriding furnace is by gas tightness of the furnace body by vacuum system, heating system, rapid cooling system composition.
Special structural design of the furnace to ensure the muffle tank when heated freely backward to avoid the stress and deformation of elongation.
The vacuum system faster, more cleanly eliminate air in the furnace and built erected a new atmosphere of process
The internal cooling system and external cooling system which can remarkably high workpiece cooling rate, improve the production efficiency.
During the last 10 years, ZHUODA has built far more than 300 this furnace running successfully in domestic and abroad, covering Southeast Asia and Middle East Asia market. This impressively proves permanent high quality, reliability and low energy consumption. ZHUODA are expecting become your long-term partner in China.
