Nylon is commonly referred to using the chemical designation “PA” (e.g., PA 6 or PA 6/66) and is most widely available in black, white, and its natural color (off-white or beige). Perhaps the most common variant for engineering applications is Nylon 6/6. Nylon 6/6 can be extruded (melted and forced through a die) and is also a suitable plastic for both injection moulding and 3D printing. It has a high melting temperature, making it an excellent substitute for metals in high-temperature environments (e.g., under the hood of a vehicle). The material’s downside is that it has relatively low-impact strength (even when compared to other plastics). Of note, the impact strength of Nylon can be improved by a process called “conditioning.” For this reason, as well as the ease with which Nylon can be combined with other materials to enhance its strength, it is important to check the material properties of the specific Nylon material you are using.
The nylon plastic injection mouldings are quick, providing an economical interest,which is similar to the pom plastic injection moulding. Polyamide 6 and Polyamide 66 answer the requirements of numerous applications in the varied markets.

Properties of Nylon Injection moulding
- High mechanical strength, good toughness, and high tensile and compressive strength.
- The fatigue resistance is outstanding, and the parts can still maintain the original mechanical strength after repeated repeated bending.
- High softening temp. and heat resistance.
- Smooth surface, low friction coefficient, wear-resistant.
- Has excellent electrical properties.
- Self-extinguishing, non-toxic, odorless, good weather resistance, inert to biological erosion, good antibacterial and anti-mildew ability.
- The parts are light in weight, easy to dye and easy to form. Because of its low melt viscosity, it can flow quickly for easy filling.
