产品详细信息

PA66注射丸

熔融温度：260~290C。玻璃添加剂的产品温度为275~280C。熔化温度应避免高于300℃

模具温度：建议为80摄氏度。模具温度会影响结晶度，结晶度会影响产品的物理性能。对于薄壁塑料零件，如果使用低于40℃的模具温度，塑料零件的结晶度将随时间变化。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，取决于材料和产品设计

注射速度：高速（增强材料略低）

流道和浇口：由于PA66的凝固时间很短，浇口的位置非常重要。闸门孔径不应小于0.5*t（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。如果使用水下闸门，闸门的小直径应为0.75mm。PA66塑料应用PA66是一种具有机械强度和广泛应用的PA系列。由于其结晶度高，其硬度和耐热性高

为了改善PA66的机械性能，经常添加各种改性剂。玻璃是一种常见的添加剂，有时会添加EPDM和SBR等合成橡胶以提高抗冲击性

Product Details

PA66 injection pellets

Melting temperature: 260~290C. The glass additive product is 275~280C. The melting temperature should be avoided higher than 300C.

Mold temperature: 80C is recommended. The mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product. for

For thin-walled plastic parts, if a mold temperature lower than 40C is used, the crystallinity of the plastic parts will change over time. In order to maintain

The geometric stability of plastic parts requires annealing treatment.

Injection pressure: usually 750~1250bar, depending on the material and product design.

Injection speed: high speed (slightly lower for reinforced materials).

Runner and gate: Since the solidification time of PA66 is very short, the location of the gate is very important. The gate aperture should not be less than 0.5*t (where t is the thickness of the plastic part). If you use a hot runner, the gate size should be smaller than using a conventional runner, because the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the small diameter of the gate should be 0.75mm. PA66 plastic application PA66 is a variety of PA series with mechanical strength and wide application. Because of its high crystallinity, its rigidity and heat resistance are high.

In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is a common additive, and sometimes synthetic rubbers such as EPDM and SBR are added to improve impact resistance.
