注塑加工產(chǎn)品的過(guò)程中實(shí)際上有很多步驟需要做好，比如說(shuō)產(chǎn)品注塑加工時(shí)的填充工作。這可是加工過(guò)程中非常重要的一個(gè)步驟，填充分為高速填充和低速填充兩種，當(dāng)然選擇高速還是低速填充是要根據(jù)產(chǎn)品來(lái)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(shí)剪切速率高，塑料因剪切變稀而粘度降低，降低了整體流動(dòng)阻力；局部粘性加熱效應(yīng)也會(huì)降低凝固層的厚度，因此在流動(dòng)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(dòng)控制階段，由于高速充填，熔體的剪切變薄效應(yīng)往往較大，薄壁的冷卻效果不明顯，因此以速度效應(yīng)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(shí)，熱傳導(dǎo)控制低速灌裝時(shí)，剪切速率低，局部粘度高，流動(dòng)阻力大。由于熱塑性塑料的補(bǔ)充速度慢，流動(dòng)慢，導(dǎo)熱效果更明顯，熱量很快被冷模壁帶走。結(jié)合較小的粘性加熱量，固化層較厚，這進(jìn)一步增加了較薄壁處的流動(dòng)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(jì)南注塑加工提醒大家，填充步驟的進(jìn)行很多時(shí)候會(huì)出現(xiàn)問(wèn)題，比如說(shuō)填充不足的現(xiàn)象存在，這個(gè)時(shí)候會(huì)導(dǎo)致注塑加工制品出現(xiàn)質(zhì)量不合格，這往往會(huì)給注塑加工廠造成不小的經(jīng)濟(jì)損失，因此注塑操作人員，需要懂得如何做好填充不足時(shí)候的解決方法才行。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(dāng)料筒末端儲(chǔ)存的材料過(guò)多時(shí)，螺桿在注射過(guò)程中會(huì)消耗額外的注射壓力來(lái)壓縮和推動(dòng)儲(chǔ)存在料筒中的多余材料，從而大大降低塑料進(jìn)入模具的有效注射壓力腔，使產(chǎn)品難以填充。這個(gè)時(shí)候就需要操作人員冷靜思考如何進(jìn)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(chǎn)品時(shí)如何進(jìn)行填充？這個(gè)問(wèn)題在上述已經(jīng)講解完畢了，操作人員在進(jìn)行這一步驟之前應(yīng)當(dāng)做好相應(yīng)的檢查工作以及相關(guān)問(wèn)題的應(yīng)對(duì)方案才行，這樣才能大大降低產(chǎn)品質(zhì)量不行的概率。更多內(nèi)容就來(lái)網(wǎng)站m.farahexin.cn咨詢吧！

　　How to fill the product when injection molding? 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.
