As high-end manufacturing evolves toward higher precision, superior surface quality, and greater reliability, mirror finishing has become one of the key technological indicators of a nation’s manufacturing capabilities.

Austenitic stainless steels typically contain high levels of chromium (≥18%), nickel (8%–25%), and other elements that enhance corrosion resistance (such as molybdenum, copper, silicon, niobium, and titanium).

As global energy constraints tighten and environmental regulations become increasingly stringent, the automotive industry is undergoing a profound materials revolution.

Due to their high specific strength, high toughness, and high-temperature resistance, titanium alloys are widely used in the aerospace, defense, and 3C industries, with consumption increasing year by year and promising market prospects.

With the rapid development of high-end manufacturing sectors such as aerospace, automotive, and medical devices, the demand for machining complex and precision parts is growing steadily.

Thanks to its high precision, flexibility, and degree of automation, CNC milling has come to play a pivotal role in mold manufacturing.

IN718 nickel-based superalloy exhibits exceptional high-temperature oxidation resistance, thermal stability, thermal corrosion resistance, and thermal fatigue resistance at temperatures above 600 °C.

In an injection molding workshop, one of the most vexing quality issues is “flash.” Though it may seem like a minor imperfection along the edges, it often becomes the direct cause of customer returns, payment deductions, or even lost orders.

In the field of mechanical manufacturing, CNC milling serves as a core machining method, and the level of its process directly determines product quality and production efficiency.
