Custom Surface Treatments

All post-processing steps increase the cost of parts and extend the production cycle, but choosing the right surface treatment can turn your design concepts into reality. For CNC (CNC) machined parts, metal surface treatments typically include various mechanical processes such as tumbling, brushing, bead blasting, and may also involve chemical surface treatments such as passivation and zinc plating.

The numerous benefits of chemical surface treatments include removing defects from parts, altering their conductivity, extending their lifespan, and improving their wear resistance and corrosion resistance. Chemical surface treatments have wide industrial applications. For example, in the aerospace industry, chemical surface treatment technology is applied to enhance the durability of parts, improve thermal stability, and slow down oxidation. In the consumer goods industry, chemical surface treatments are used in the production of casings, enclosures, and sports equipment.

Metalcnc Precision Machining Processes and Their Working Principles

Metal finishing is the process of changing the surface of an object using various techniques to improve appearance and performance, such as corrosion resistance, discoloration resistance, chemical resistance, wear resistance, and hardness, modifying conductivity, removing burrs, or applying specific colors to machined parts.

It typically involves adding a layer of metal or non-metal coating to the outer surface of a metal workpiece, while also cleaning the parts. Metal surface finishing services are commonly used for CNC machined parts made of aluminum, stainless steel, brass, and other materials.
