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

为了提高 PA66 的机械特，经常加入各种各样的改剂。玻璃就是常见的添加剂，有时为了提高抗冲击还 加入合成橡胶，如 EPDM 和 SBR 等。
In order to improve the mechanical properties of PA66, various modifiers are often added. Gss is the most coon additive, and sometimes synthetic rubber, such as EPDM and SBR, is added to improve the impact resistance.

PA66 的粘较低，因此流动很好（但不如 PA6）。这个质可以用来加工很薄的元件。 它的粘度对温度变化很敏感。PA66 的收缩率在 1%~2%之间，加入玻璃纤维添加剂可以将收缩率降低到 0.2%~1% 。收缩率在流程方向和与流程方向相垂直方向上的相异是较大的。
PA66 has low viscosity, so it has good fluidity (but not as good as PA6). This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. The shrinkage of PA66 is in the range of 1% ~ 2%, and it can be reduced to 0.2% ~ 1% by adding gss fiber additive. The difference of shrinkage rate in the process dirion and in the dirion perpendicur to the process dirion is rger.
