Die casting process that improves the pressure resistance and airtightness of the pressurized section [Precision Localized Pressurization Method].

The pressure resistance and airtightness of the pressurized section will improve. Even if the area around the pressurized section is machined, the appearance of visible surface defects on the machined surface will be significantly reduced.

It can be used in conjunction with general die casting, and by applying pressure in accordance with the directional solidification of the pressurized peripheral area, it is possible to suppress the occurrence of shrinkage cavities inside the product. There are proven results in parts for car air conditioning compressors and other hydraulic control components that require very high pressure airtightness. We have established our own unique condition setting and management, ensuring a very high level of quality stability. Even with a very short pressurization stroke, which is uncommon in other companies, we can achieve precise control by integrating local pressurization control devices with our proprietary technology. Based on the accumulation of past data, it is possible to suppress the side effects associated with local pressurization (such as cracking and peeling) through the setting of pressurization conditions. 【Features】 ■ Increased pressure airtightness ■ Significant reduction in visible surface cavities ■ High level of quality stability *For more details, please download the materials or contact us.
