Nylon or polyamide is a low-friction plastic polymer with high impact, chemical, and abrasion resistance. It is applicable in the electrical and automotive industries in making parts such as keyboard caps, electronic enclosures, and car dashboard components. It has a low melting point which can cause deformation from heat generated by the CNC machine.ĪBS is a very popular engineering thermoplastics used by many rapid prototyping services in making products due to its excellent properties and affordability.You need proper ventilation to prevent the buildup of such gases.It releases hot plastic fumes when subjected to heat.ABS has high durability, which means a longer lifespan.ABS has a low melting point suitable (this is important for other rapid prototyping processes such as 3D printing and injection molding).The plastic polymer is highly machinable, making it a highly popular rapid prototyping material.It is lightweight without losing its mechanical strength.Also, the thermal stability of pure ABS (i.e., ABS without additives) is low, as the plastic polymer will burn even after removing the flame. Although it boasts good mechanical properties, its low chemical stability is evident in its susceptibility to greases, alcohols, and other chemical solvents. Below are the most common plastics for custom plastic machining: ABSĪcrylonitrile Butadiene Styrene, or ABS, is a lightweight CNC material known for its impact resistance, strength, and high machinability. ![]() Their use depends on their properties, with some machinable plastics, such as nylon, having excellent mechanical properties that allow them to replace metals. Many machinable plastics are suitable for manufacturing parts and products several industries manufacture. ![]() How much do you know about plastic CNC machining? This article discusses the materials compatible with the process, available techniques, and other things that can help your project. Furthermore, with the introduction of computer numerical control, the process becomes more accurate, faster, and suitable for making parts with tight tolerance. The acceptance of plastic machining as a manufacturing process is due to the wide array of plastic CNC materials available. However, not only is CNC machining widely applicable to plastics, but plastic CNC machining is also one of the common machining processes in several industries. A common depiction of CNC machining, most times, involves working with a metallic workpiece.
