Experimental cold isostatic press is a device used for material forming, which applies uniform pressure to powder materials through liquid or gas media at room temperature to make them compact and form. It is widely used in powder metallurgy, composite materials, ceramics and other fields.
The experimental cold isostatic press is based on Pascal's principle, which places powder or solid workpieces sealed in a flexible mold in a high-pressure container and applies pressure to liquid media (such as water or oil) through a hydraulic system. Due to the incompressibility of liquids, pressure is evenly transmitted to the surface of the mold, causing the material to be compressed in all directions simultaneously, achieving particle rearrangement and plastic deformation, and obtaining high-density molded bodies.
The working principle of the experimental cold isostatic press is based on Pascal's law, which states that "the pressure of any liquid or gas in a closed container can be uniformly transmitted in all directions". It uses liquid as a pressure transmission medium to place the product in a sealed container filled with liquid. Under high pressure, equal pressure is applied to each surface of the product to increase its density and obtain the desired shape.
Features:
High uniformity: eliminates local stress concentration in traditional mechanical pressing, ensuring uniform sample density and structure.
Complex shape processing capability: capable of suppressing samples with irregular shapes or complex internal structures, with good forming effects.
High precision control: supports pressure curve setting and segmented adjustment to meet the process requirements of different materials.
Data traceability: Record pressure cycle data throughout the entire process for easy comparison of molding effects under different processes.
Compact design: Height less than 1.5 meters, small footprint, suitable for laboratory environment.
structural composition
High pressure vessel: used to hold liquids and products to be compressed, usually made of high-strength materials such as prestressed steel winding structures to withstand high pressure.
Hydraulic system: including hydraulic pumps, hydraulic cylinders, valves, etc., used to provide high-pressure fluid, achieve pressure application and control.
Control system: generally composed of sensors, controllers, and display screens, it can accurately set and control parameters such as pressure, pressure rise and fall speed, and record pressure cycle data.
Safety devices: such as emergency stop buttons, emergency unloading devices, pressure sensors, and electrical control systems, to ensure the safe operation of equipment.
