Although the initial investment of hydraulic presses may be higher, they are more efficient when handling large-scale production and are suitable for the needs of the medical industry. In addition, the pressing of zirconium oxide powder may require higher pressure, which is more advantageous for hydraulic presses than pneumatic or other types of presses.
Zirconia powder may not have good flowability and requires uniform pressure distribution to avoid defects after pressing. The large-area pressure application of hydraulic presses may be more effective, ensuring uniform density across the entire compact, which is critical for the subsequent sintering step, otherwise uneven density may cause deformation or insufficient strength.
The adjustability of the hydraulic press. Different products may require different pressure parameters. The hydraulic press can be flexibly adjusted to meet the production needs of a variety of products. In addition, the hydraulic system may be better in overload protection to avoid damage to the mold or equipment due to excessive pressure, which is particularly important for the production of high-value medical devices.
