Materials for High Volume CNC Machining
Material selection is one of the most critical decisions in any CNC machining project. Choosing the wrong material can lead to premature part failure or rework costs following mass production. DSR has comprehensive processing capabilities for metal alloys and engineering plastics. Simply provide us with your specific requirements or design drawings, and we will help you select the right material.

And we have mature experience in process parameters and batch delivery for each material.
If your parts require insulation, lightweight properties, or chemical corrosion resistance, engineering plastics are also a reasonable choice. DSR supports precision machining of mainstream engineering plastics such as PEEK, Delrin, nylon, and acrylic. Moreover, the dimensional stability and surface quality of plastic parts also meet industrial-grade standards.
Surface Finishing for High Volume CNC Machining
We deeply integrate CNC precision machining with large-scale surface treatment. From single-piece prototyping to mass production of 10,000 pieces, each batch of parts maintains the same processing standards and appearance quality.
Through heat treatment methods such as quenching and tempering, the strength and hardness of parts can be greatly enhanced. In mass production, DSR can ensure that the mechanical properties of each part remain consistent and stable.
In applications with stringent precision tolerance requirements, grinding is the most effective surface treatment method for achieving micron-level dimensional accuracy and extremely low surface roughness. DSR’s grinding process can control surface roughness to less than Ra 0.2.
The preferred surface treatment solution for aluminum alloy parts. Through the anodizing process, a dense oxide layer forms on the surface of the parts, significantly enhancing their corrosion resistance and surface hardness. And this process also supports color customization such as natural color, black, blue and so on.
Electroplating can precisely deposit metal coatings on the surface of parts, imparting them specific functional properties such as conductivity, wear resistance, or corrosion resistance. And the coating thickness of these parts is uniform and controllable.
This process is to electrostatically adsorb the powder coating to the surface of the part and solidify it at high temperature to form a strong and dense protective coating. This layer makes the part more resistant to corrosion and impact.
We spray abrasives at high speed to evenly remove the oxide layer, machining marks and residual stress on the surface of the part, thereby forming a fine and consistent matte texture on the surface of the part. This process can effectively enhance the aesthetic quality of the parts.
This process deposits a high-hardness chromium coating on the surface of the part, with a hardness of HV 900 or higher. This significantly improves the wear and corrosion resistance of the part.
The phosphating process can form a phosphate conversion coating on the surface of steel. It provides basic anti-rust protection while greatly enhancing the adhesion of subsequent coatings.
