塑料材料在生活中所占比例越來越高,而對(duì)于其質(zhì)量的要求也越來越高,注塑成型作為重要的生產(chǎn)手段,對(duì)技術(shù)的提高也越來越迫切,而注塑成型制品的影響因素較多,但注塑成型加工工藝條件是重要的影響因素之一,那么工藝參數(shù)對(duì)于塑料模具制品性能的影響是怎樣的?
The proportion of plastic materials in life is higher and higher, and the requirements for their quality are higher and higher. As an important means of production, injection molding is more and more urgent to improve technology. There are many influencing factors of injection molding products, but the processing conditions of injection molding are one of the important influencing factors. What is the impact of process parameters on the performance of plastic mold products?
傳統(tǒng)的模具設(shè)計(jì)和工藝參數(shù)設(shè)置主要依賴于設(shè)計(jì)者的經(jīng)驗(yàn)和技巧,模具設(shè)計(jì)的合理性只有靠反復(fù)的試模和修模,工藝參數(shù)的設(shè)置也只能靠反復(fù)的試模來進(jìn)行修改,缺乏科學(xué)依據(jù),生產(chǎn)周期長(zhǎng),成本高,質(zhì)量也難以保證。
The traditional mold design and process parameter setting mainly depend on the experience and skills of the designer. The rationality of mold design only depends on repeated mold trial and repair, and the setting of process parameters can only be modified by repeated mold trial. It lacks scientific basis, long production cycle, high cost and difficult to guarantee the quality.
而對(duì)成型過程進(jìn)行模擬,在模具制造之前就可發(fā)現(xiàn)設(shè)計(jì)中的問題,使模具設(shè)計(jì)和工藝參數(shù)設(shè)置建立在科學(xué)的分析基礎(chǔ)之上,可縮短生產(chǎn)周期,提高制品質(zhì)量。隨著對(duì)制品質(zhì)量要求的提高,對(duì)成型過程進(jìn)行預(yù)測(cè)己經(jīng)成為設(shè)計(jì)不可缺少的環(huán)節(jié)。因此,建立注塑成型過程熔體在模腔中流動(dòng)和傳熱的數(shù)學(xué)模型,并采用數(shù)值仿真方法實(shí)現(xiàn)成型過程的模擬具有重要的意義。
By simulating the forming process, the problems in the design can be found before the mold manufacturing, so that the mold design and process parameter setting are based on scientific analysis, which can shorten the production cycle and improve the product quality. With the improvement of product quality requirements, the prediction of forming process has become an indispensable link in design. Therefore, it is of great significance to establish the mathematical model of melt flow and heat transfer in the mold cavity in the injection molding process, and use the numerical simulation method to simulate the molding process.
由于成型過程的工藝參數(shù)直接決定了熔體在模腔中的流動(dòng)狀態(tài),對(duì)制品質(zhì)量有著很直接很深遠(yuǎn)的影響,因此找到制品成型的很優(yōu)工藝條件,對(duì)成型過程進(jìn)行工藝控制,是提高塑料制品質(zhì)量的有效途徑。
Because the process parameters of the molding process directly determine the flow state of the melt in the mold cavity and have a very direct and far-reaching impact on the product quality, finding the excellent process conditions for product molding and controlling the molding process is an effective way to improve the quality of plastic products.
山東模具制造廠家認(rèn)為這是因?yàn)槌尚瓦^程中,精密的成型機(jī)械、合理的模具設(shè)計(jì)和優(yōu)良的材料性能只有在合理的成型工藝設(shè)置下才能體現(xiàn)出來另一方面,成型機(jī)械、模具設(shè)計(jì)和材料性能的缺陷有時(shí)可通過合適的成型工藝設(shè)置來彌補(bǔ)。由此可見,注塑成型工藝對(duì)制品質(zhì)量有著關(guān)重要的作用。
Shandong mold manufacturers believe that this is because in the molding process, the precise molding machinery, reasonable mold design and excellent material performance can only be reflected under the reasonable molding process setting. On the other hand, the defects of molding machinery, mold design and material performance can sometimes be made up through the appropriate molding process setting. It can be seen that injection molding process plays a vital role in product quality.
注塑成型加工工藝條件對(duì)塑料制品的表觀和力學(xué)性能造成影響,每一個(gè)工藝條件參數(shù)都相互影響并不是獨(dú)立的,有些制品的缺陷是相互影響的結(jié)果。所以要想更好的保證注塑產(chǎn)品后的質(zhì)量就要多多了解相關(guān)問題,可以來網(wǎng)站

Injection molding process conditions affect the apparent and mechanical properties of plastic products. Each process condition parameter affects each other, which is not independent. The defects of some products are the result of mutual influence. Therefore, if you want to better ensure the quality of injection molded products, you need to know more about relevant problems.
