Shaanxi Zhituo has researched and developed four generations of vacuum diffusion bonding equipment with proprietary intellectual properties. The designed working temperature of the equipment is within the range of 1250 ~ 1500 °C. The pressure modes are from single-axis, single-cylinder to muti-axis, muti-cylinder pressure, and the tonnage is from 12 t to 1200 t. The heating zone covers from 300 × 300 × 300 mm3 ~800× 800 × 1200 mm3. Cooling plate, microchannel heat exchangers and other large complex structures within 800 × 1200 mm2 can be researched, developed and mass produced.
