PA66 美国杜邦 8018HS plastic raw materials
PA66 美国杜邦 8018HS Injection mold process conditions
PA66 美国杜邦 8018HS Drying process: if processing former material is sealed, then there is no need to dry. However, if the storage vessel is opened, it is recommended that in 85 c hot air drying process. If the humidity is more than 0.2%, but also the need for 105 c, 12 hours of vacuum drying.
PA66 美国杜邦 8018HS Melting temperature: 260 ~ 290 c. For glass additive products for 275 ~ 280 c. Melting temperature should avoid to higher than 300 c. Mold temperature: it is recommended that 80 c. Mold temperature will influence the degree of crystallinity, degree of crystallinity will affect the product’s physical characteristics. For thin wall plastic parts, if you use less than 40 c mold temperature, the plastic parts of the degree of crystallinity will changes with a time, in order to keep the stability of the geometry of the plastic parts, the need for annealing treatment.
PA66 美国杜邦 8018HS Injection pressure: usually in 750 ~ 1250 bar, depends on the material and product design.
PA66 美国杜邦 8018HS Injection speed: high speed (for enhanced materials should be slightly lower).
PA66 美国杜邦 8018HS Runner and gate: because of PA66 the coagulation time is very short, so gate position is very important. Gate aperture not less than 0.5 * t (here t for plastic parts thickness). If you use hot runner, gate size should compare with conventional runner small a few, because of hot runner can help prevent premature solidification materials. If you use submarine gate, gate of the minimum diameter should be 0.75 mm.
PA66 美国杜邦 8018HS Typical application PA66 more widely used in automotive industry, instrument shell and other need to have impact resistance and high strength requirements of the product.
