注塑加工产品的过程中实际上有很多步骤需要做好，比如说产品注塑加工时的填充工作。这可是加工过程中非常重要的一个步骤，填充分为高速填充和低速填充两种，当然选择高速还是低速填充是要根据产品来决定的。

　　In fact, there are many steps to be done in the process of injection molding products, such as the filling work of injection molding products. This is a very important step in the processing process, filling is divided into high speed filling and low speed filling two kinds, of course, choose high speed or low speed filling is to decide according to the product.

　　注塑加工的高速填充时剪切速率高，塑料因剪切变稀而粘度降低，降低了整体流动阻力；局部粘性加热效应也会降低凝固层的厚度，因此在流动控制阶段，填充行为往往取决于待填充体积的大小。即在流动控制阶段，由于高速充填，熔体的剪切变薄效应往往较大，薄壁的冷却效果不明显，因此以速度效应为主。

　　Injection molding process of high speed filling shear rate, plastic shear thinning and viscosity reduction, reduce the overall flow resistance; The local viscous heating effect also reduces the thickness of the solidified layer, so the filling behavior often depends on the volume to be filled in the flow control stage. In other words, in the flow control stage, due to high-speed filling, the shear thinning effect of melt is usually large, while the cooling effect of thin wall is not obvious, so the velocity effect is mainly.

　　注塑加工的低速填充时，热传导控制低速灌装时，剪切速率低，局部粘度高，流动阻力大。由于热塑性塑料的补充速度慢，流动慢，导热效果更明显，热量很快被冷模壁带走。结合较小的粘性加热量，固化层较厚，这进一步增加了较薄壁处的流动阻力。

　　Low speed filling of injection molding process, heat conduction control low speed filling, low shear rate, high local viscosity, flow resistance. Because the thermoplastic supplement speed is slow, the flow is slow, the heat conduction effect is more obvious, the heat is quickly taken away by the cold mold wall. Combined with less viscous heat, the curing layer is thicker, which further increases flow resistance at thinner walls.

　　济南注塑加工提醒大家，填充步骤的进行很多时候会出现问题，比如说填充不足的现象存在，这个时候会导致注塑加工制品出现质量不合格，这往往会给注塑加工厂造成不小的经济损失，因此注塑操作人员，需要懂得如何做好填充不足时候的方法才行。比如：

　　Jinan injection molding processing, the steps to a lot of time there will be a problem, such as insufficient filling phenomenon exists, this time can lead to injection molding products processing appear to be of poor quality, it tends to give injection molding processing factory causing economic losses, so injection operation personnel, need to know how to do when insufficient filling solution. Such as:

　　当料筒末端储存的材料过多时，螺杆在注射过程中会消耗额外的注射压力来压缩和推动储存在料筒中的多余材料，从而大大降低塑料进入模具的有效注射压力腔，使产品难以填充。这个时候就需要操作人员冷静思考如何进行处理了。

　　When there is too much material stored at the end of the barrel, the screw will consume extra injection pressure during the injection process to compress and push the excess material stored in the barrel, thus greatly reducing the effective injection pressure cavity of plastic into the mold, making the product difficult to fill. At this time, the operator needs to think calmly about how to deal with it.

　　注塑加工产品时如何进行填充？这个问题在上述已经讲解完毕了，操作人员在进行这一步骤之前应当做好相应的检查工作以及相关问题的应对方案才行，这样才能大大降低产品质量不行的概率。更多内容就来网站www.sdlqmj.com咨询吧！

This problem has been explained in the above, the operator should do a good job in the corresponding inspection work and related problems before this step, so as to greatly reduce the probability of product quality is not good.
