注塑加工產品的過程中實際上有很多步驟需要做好，比如說產品注塑加工時的填充工作。這可是加工過程中非常重要的一個步驟，填充分為高速填充和低速填充兩種，當然選擇高速還是低速填充是要根據產品來決定的。
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時剪切速率高，塑料因剪切變稀而粘度降低，降低了整體流動阻力；局部粘性加熱效應也會降低凝固層的厚度，因此在流動控制階段，填充行為往往取決于待填充體積的大小。即在流動控制階段，由于高速充填，熔體的剪切變薄效應往往較大，薄壁的冷卻效果不明顯，因此以速度效應為主。
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時，熱傳導控制低速灌裝時，剪切速率低，局部粘度高，流動阻力大。由于熱塑性塑料的補充速度慢，流動慢，導熱效果更明顯，熱量很快被冷模壁帶走。結合較小的粘性加熱量，固化層較厚，這進一步增加了較薄壁處的流動阻力。
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.
濟南注塑加工提醒大家，填充步驟的進行很多時候會出現問題，比如說填充不足的現象存在，這個時候會導致注塑加工制品出現質量不合格，這往往會給注塑加工廠造成不小的經濟損失，因此注塑操作人員，需要懂得如何做好填充不足時候的方法才行。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:
當料筒末端儲存的材料過多時，螺桿在注射過程中會消耗額外的注射壓力來壓縮和推動儲存在料筒中的多余材料，從而大大降低塑料進入模具的有效注射壓力腔，使產品難以填充。這個時候就需要操作人員冷靜思考如何進行處理了。
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.
注塑加工產品時如何進行填充？這個問題在上述已經講解完畢了，操作人員在進行這一步驟之前應當做好相應的檢查工作以及相關問題的應對方案才行，這樣才能大大降低產品質量不行的概率。更多內容就來網站
