Isostatic pressing mould is a special industrial mould different from traditional low-pressure moulds, stamping moulds and extrusion moulds, mainly used for powder metallurgy, ceramic materials, hard alloy and new material forming processing. It relies on uniform hydraulic pressure to realize three-dimensional stress balance forming, solving the problems of uneven density and local stress concentration of traditional compression mould products. Xinfeng Machinery masters customized manufacturing technology of isostatic pressing moulds, adapting to high-precision forming needs of various new industrial materials.
The core working advantage of isostatic pressing moulds is uniform pressure bearing. Ordinary模压 moulds rely on unidirectional mechanical pressure, resulting in 15%-20% density difference between product surface and core. Isostatic pressing equipment transmits pressure through liquid medium, making the mould bear uniform three-dimensional pressure, with pressure uniformity up to 99.5%. This process can compress powder materials to ultra-high compactness of 99.7%, greatly improving product hardness, wear resistance and structural stability.
In terms of structural design, isostatic pressing moulds adopt flexible composite structure, which can fit irregular and special-shaped product contours without dead-angle pressing. Different from rigid metal moulds such as aluminum extrusion moulds and low-pressure casting moulds, flexible moulds will not produce rigid extrusion marks on product surfaces, ensuring complete product outline and smooth surface. For complex special-shaped parts such as aerospace ceramic components and hard alloy tools, isostatic pressing moulds are the only reliable forming tool.
In terms of service life and cost performance, high-quality customized isostatic pressing moulds can stably complete 20,000+ pressing cycles, while ordinary inferior moulds only last 5,000 cycles. Long-term use can reduce mould replacement and equipment debugging costs by 40%. In addition, the product finished product rate of isostatic pressing process is as high as 98%, which is 32% higher than traditional die pressing, greatly reducing raw material waste and production loss.
Industrial application scenarios are highly targeted, mainly covering new energy materials, aerospace precision parts, electronic ceramic components and high-hardness alloy tools. It cannot be replaced by low-pressure die casting moulds, stamping moulds and stretching moulds in high-density new material forming fields, with unique industrial technical advantages.
