Nylon PA612 has high fluidity and is easy to demold. It has a short molding cycle and is resistant to strong alkalis, ensuring the complete molding of precision thin-walled injection molded products, especially products such as sealing rings and gaskets. The material has low water absorption, is translucent, and has excellent toughness.
Drying treatment: If the material is sealed before processing, there is no need for drying. However, if the storage container is opened, it is recommended to dry it in hot air at 85°C. If the humidity is greater than 0.2%, vacuum drying at 105°C for 12 hours is also required. Mold humidity: It is recommended to be 80°C. The mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product. For thin-walled plastic parts, if a mold temperature below 40°C is used, the crystallinity of the plastic parts will change over time. To maintain the geometric stability of the plastic parts, annealing treatment is required. Injection pressure: Usually between 750~1250 bar, depending on the material and new product design. Injection speed: High speed (slightly lower for reinforced materials). Runners and gates: Since the solidification time of PA612 is very short, the location of the gate is very important. The gate aperture should not be less than 0.5*t (where t is the thickness of the plastic part). If a hot runner is used, the gate size should be smaller than that when using a conventional runner because the hot runner can help prevent the material from solidifying prematurely. If it is a submarine gate, the minimum diameter of the gate should be 0.75mm
