Hot Isostatic Pressing (HIP) is an advanced material processing equipment that integrates high temperature and high pressure. It uses inert gas (usually argon) as the pressure medium to apply uniform high temperature and high pressure to the workpiece simultaneously, achieving material densification, defect repair, or dissimilar material connection. Its core feature is the uniform distribution of pressure and temperature in the three-dimensional direction of the workpiece, which is suitable for the overall processing of complex shaped parts and widely used in high-end manufacturing fields such as aerospace, nuclear power, and medical.
PRODUCT DESCRIPTION
1. Heating and pressure boosting stage: The workpiece is placed in a closed pressure vessel (usually made of heat-resistant alloy or ceramic material), and an inert gas (such as argon) is introduced into the vessel. The temperature is raised to near the softening point of the material (usually 0.5-0.8 times the melting point) through a heating system (resistance heating or induction heating), and the gas pressure is increased to 100-300 MPa (up to 500 MPa or more) through a compressor.
2. Insulation and pressure holding stage: Maintain a certain period of time (from tens of minutes to several hours) under the set high temperature and pressure. At this time, defects such as pores and cracks inside the material are "compacted" under pressure, and atomic diffusion is intensified, achieving grain reorganization and densification; If used for welding, the atoms at the contact surface penetrate each other to form a metallurgical bond.
3. Cooling and pressure reduction stage: Slowly reduce temperature and pressure to avoid deformation or cracking of the workpiece due to stress concentration, ultimately obtaining dense and uniform materials or joints.
