With the rapid development of the manufacturing industry, CNC (Computer Numerical Control) machining technology has become a key force driving industrial progress. In China, Xiamen Goldcattle, a national high – tech enterprise, focuses on the research, development, and manufacturing of high – precision injection – molded parts, high – precision mechanical parts, stamping parts, plastic injection – molded parts, and injection – molded components. This showcases the excellent application of CNC machining technology in the field of precision manufacturing. This article will delve into the differences in plastic materials, CNC part customization cases, surface treatment processes, customization procedures, and FAQs, aiming to provide readers with comprehensive knowledge of CNC machining.
Comparison of Plastic Materials
In CNC machining, choosing the right plastic material is of crucial importance. The following is a comparison of several common plastic materials presented in a technical document style:
| Material Type | Physical Properties | Functional Indicators | Applicable Scenarios | Economy | Mass – production Feasibility |
|---|---|---|---|---|---|
| ABS | High strength, impact – resistant | Good machinability, surface gloss | Electronic product casings, automotive parts | Medium | High |
| PC | High transparency, high toughness | Excellent heat resistance, weather resistance | Optical lenses, medical equipment | Relatively high | Medium |
| PP | Lightweight, corrosion – resistant | Good insulation, machinability | Containers, pipeline systems | Low | High |
| PA66 | High strength, wear – resistant | Good self – lubrication, heat resistance | Mechanical parts, transmission components | Relatively high | Medium |
Engineers’ Material Selection Advice: When choosing plastic materials, it is necessary to comprehensively consider the product’s usage environment, performance requirements, and cost budget. For example, for products that need to withstand high impact forces, ABS is an ideal choice; while for applications that require transparency and heat resistance, PC is more suitable.

Surface Treatment Processes
Anodizing: An oxide film is formed on the metal surface through electrolysis to improve corrosion resistance and aesthetics. It is suitable for metal products such as aluminum alloys.
Sandblasting Treatment: High – speed jet abrasive is used to clean and roughen the metal surface, enhancing the adhesion of the coating. It is suitable for products that need to increase the adhesion of the coating.
Electroplating: A metal or alloy layer is deposited on the metal surface to improve corrosion resistance, decorativeness, and electrical conductivity. It is applicable to electronic products, automotive parts, etc.
