Our company has been supplying the following nylon models for a long time：
PA66 and PA6 are the main varieties of nylon, oupying an absolute dominant ition. ong the five engineering pstics, PA66 and PA6 he the rgest yield, the most varieties and the most widely used varieties. Nylon 6 is polycaproct, while nylon 66 is polyhexanediine, and nylon 66 is 12% harder than nylon 6; next are nylon 11, nylon 12, nylon 610, nylon 612, and nylon 1010, nylon 46, nylon 7, nylon 9, and nylon 13. New varieties include nylon 6I, nylon 9t and special nylon MXD6 (barrier resin). There are many varieties of nylon modified, such as reinforced nylon, nylon 610 and nylon 612 Monomer casting nylon (MC nylon), reaction injion molding (RIM) nylon, aromatic nylon, tranrent nylon, high impact (super tough) nylon, elropted nylon, conductive nylon, fle retardant nylon, blends and alloys of nylon and other polymers meet different special requirements, and are widely used as substitutes for traditional materials such as metal and wood.

PA66具有优良的耐磨、自润滑，机械强度较高。但吸水较大，因而尺寸稳定较差
PA66 has excellent wear resistance, self lubrication and high mechanical strength. However, the size stability is poor because of its high water absorption

Runner and gate of PA66 processing: because the solidification time of PA66 is very short, the location of gate is very important. The gate dieter should not be less than 0.5 * t (where t is the thickness of the pstic part). If a hot runner is used, the gate size should be smaller than that of a conventional runner, as the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the minimum dieter of the gate should be 0.75.

PA66加工模具温度：建议 80℃。模具温度将影响结晶度，而结晶度将影响产品的物理特。对于 薄壁塑件，如果使用低于 40℃ 的模具温度，则塑件的结晶度将随着时间而变化，为了保持 塑件的几何稳定，需要进行退火处理。
