Information about PA6/PA66 (Nylon) Injection Molding. Mechanical Akulon has a full portfolio that provides excellent long- and short-term mechanical properties. Check for the hating location and the process parameters for stressed injection. Nylon is the most often specified fiber-reinforced thermoplastic material. Nylon plastic injection molding material can be used in a great diversity of application projects, including clothing, rubber material reinforcement such as car tires, applications as a rope or a thread, as well as a great number of plastic injection molded vehicle parts and mechanical equipment. As shown in Figure 1.1, the melt viscosity of nylon is highly dependent on temperature, so control the molding temperature closely. This grade has excellent flow and improved ambient and low temperature toughness. Good fluidity, easy to flash Nylon molding shrinkage is distinct, easy to have shrinkage cavity and deformation. About us PO Procedure Forum. Information about PA6/PA66 (Nylon) Injection Molding. Akulon is ideal for injection molding thanks to its unique combination of short- and long-term low and high temperature properties under various chemical conditions. Nylon 6 molding performance: Crystalline materials, high melting point and narrow melting temperature range, poor thermal stability, if melt temperature is over 300 degrees and PA stay in injection molding barrel more than 30 min, it will be decomposed. So your nylon moisture content is actually 0.24%—too wet to process. NY66 and NY6 (Nylon 6,6 and Nylon 6) are semi-crystalline engineering thermoplastics that can be easily colored, and that can be easily processed in both injection molding, and extrusion applications. The actual shrinkage is related with the plastic part design, wall thickness and other process parameters. PA66 is still hygroscopic after injection molding, of which the extent depends primarily on the composition of the material, the wall thickness and the environmental conditions. If you have 30% glass and 70% nylon in your compound, with 0.17% moisture you have actually have 0.17 kg of water in 70 kg of nylon. Advantages and Disadvantages of PA(nylon)6 and PA66(nylon) with additives. Plastic part and fan gate geometry. INJECTION MOULDING OF LONG GLASS FIBER REINFORCED POLYAMIDE 66 FIGURE 1. Nylon 6 Processing Parameters General Recommendations: Reciprocating screw machines Nylon screw Flow through nozzle Reverse taper nozzle ... Material should be dried to a 0.2% moisture level Injection Speed and Injection Pressure: To obtain the best possible surface finish, a moderate to fast injection speed is recommended. The maximum permissible drying temperatures lie in the range of about 80 to 110 °C. Before you injection-mold nylon. PA 66- Nylon 66. Drying before processing is highly recommended : moisture content should be a maximum of 0.2%. • Injection Molding: - It is a cyclic process, where a heat soften material injected in to close mold, which gives the desired shape. Top.

Nylons are widely used because they have a good cost to performance ratio. Table 1.1 shows the melting and molding temperatures for nylon.
