PA612树脂

PA612树脂也称为聚酰胺612或尼龙612，其成分为聚十二烷二己二胺。除了PA的一般特性外，PA612还具有相对较小的宽度、较低的吸水率和密度、良好的尺寸稳定性、较高的拉伸强度、冲击强度和透明度

干燥处理：

如果材料在加工前密封，则无需干燥。但是，如果打开存储容器，建议在85°C的热空气中干燥。如果湿度大于0.2%，则需要在105℃下真空干燥12小时

霉菌湿度：

建议温度为80℃。模具温度会影响结晶度，结晶度会影响产品的物理性能。对于薄壁塑料件，如果模具温度低于40℃，塑料件的结晶度将随时间而变化。为了保持塑料零件的几何稳定性，需要进行退火处理

注射压力：

通常为750~1250bar，具体取决于材料和新产品设计

注射速度：

高速（增强材料稍低）。流道和浇口：由于PA612的凝固时间很短，浇口的位置非常重要。浇口直径不应小于0.5（其中t是塑料件的厚度）。如果使用热流道，浇口尺寸应小于使用常规流道，因为热流道有助于防止材料过早凝固。如果是水下闸门，闸门的最小直径应为0.75mm

Product Details

PA612 Resin

PA612 is also called polyamide 612 or nylon 612, and its component is polydodecanedioic hexamethylene diamine. In addition to the general PA characteristics, PA612 also has the advantages of relatively small width, lower water absorption and density, good dimensional stability, high tensile strength, impact strength, and transparency.

Drying treatment:

If the material is sealed before processing, then there is no need to dry. However, if the storage container is opened, it is recommended to dry in 85°C hot air. If the humidity is greater than 0.2%, it needs to be vacuum dried at 105℃ for 12 hours.

Mold humidity:

It is recommended that 80℃. The mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product. For thin-walled plastic parts, if the mold temperature is lower than 40 ℃, the crystallinity of the plastic parts will change with time. In order to maintain the geometric stability of the plastic parts, annealing treatment is required.

Injection pressure:

Usually 750~1250bar, depending on the material and new product design.

Injection speed:

High speed (slightly lower for reinforced materials). Runner and gate: Because the setting time of PA612 is very short, the location of the gate is very important. The gate diameter should not be less than 0.5 (where t is the thickness of the plastic part). If a hot runner is used, the gate size should be smaller than using a conventional runner, because the hot runner can help prevent the material from solidifying prematurely. If submerged gate, the minimum diameter of the gate should be 0.75mm.
