2. Improved Metal Properties The rapid cooling offered by jet cooling can lead to better mechanical properties in the castings. Fine microstructures result from quicker solidification rates, enhancing attributes such as strength, hardness, and ductility. This means that components manufactured using jet cooling can meet more stringent service requirements, ultimately resulting in higher quality products.

Understanding Investment Casting

Ang sand casting core ay isang piraso ng materyal na, madalas ay gawa sa buhangin at binder, ay ginagamit upang lumikha ng mga butas o iba pang mga espesyal na hugis sa loob ng isang cast na bahagi. Ang mga cores ay inilalagay sa isang mold bago ang metal na likido ay ibinuhos dito. Sa pamamagitan ng paggamit ng cores, madali nating nakakamit ang mas kumplikadong geometry na hindi kayang makuha sa simpleng mold.

Standoff distance refers to the gap between the nozzle and the surface of the workpiece. This distance can significantly affect the energy and concentration of the abrasive jet. A shorter standoff distance can enhance the impact force of the jet, resulting in a higher MRR, but may also cause excessive wear on the nozzle. Conversely, increasing this distance may spread the abrasive jet, potentially reducing the machining efficacy. Adjusting the standoff distance is essential for fine-tuning the AJM process based on the desired outcome.
