PA66加工的流道和浇口:由于 PA66 的凝固时间很短，因此浇口的位置非常重要。浇口孔径不要小于 0.5*t（这里 t 为塑件厚度）。如果使用热流道，浇口尺寸应比使用常规流道小一些， 因为热流道能够帮助阻止材料过早凝固。如果用潜入式浇口，浇口的小直径应当是0.75。

Zytel® PA66/6应用运动用品使用的塑料：
头盔制造商 DXL-Protion 选择杜邦™ Zytel®尼龙树脂的原因是它的高耐受、刚和韧。 这款**韧尼龙采用了 33% 的玻璃纤维进行强化。 采用 Zytel® 制造的四个头盔零件分别是外壳、头部周围的 C 形“扣带”和两个侧外壳。 获得**的四部件设计使这种头盔比传统的单部件头盔更适合头部。

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.

PA66 processing mold temperature: recoended 80 ℃. Mold temperature will aff the crystallinity, which will aff the physical properties of the product. For thin-walled pstic parts, if the mold temperature is lower than 40 ℃, the crystallinity of the pstic parts will change with time. In order to maintain the geometric stability of the pstic parts, annealing treatment is needed.
Application fields of PA66:
1. It is widely used in machinery, instrumentation, automobile parts, elronic and elrical, railway, household appliances, counication, textile machinery, sports leisure goods, oil pipe, oil tank and some precision engineering products.
2. Elrical and elronic equipment: connor, reel, timer, cover circuit breaker, switch housing base
Automobile: radiator n, door handle, fuel tank cover, air intake grille, water tank cover, lp holder
3. Industrial parts: chair seat, bicycle fre, skate base, textile shuttle, pedal, slide conveyor
