在注塑過程中，由于多種因素，注塑件出現(xiàn)收攏或部分收攏，對產(chǎn)品的損壞是的。什么情況下容易出現(xiàn)這種收攏狀態(tài)呢？
In the injection molding process, due to many factors, the injection molded parts are folded or partially folded, and the damage to the product is unique. Under what circumstances is this state of collapse easy to occur?
一般來說，當(dāng)厚度大于5mm時，注塑件容易收攏；當(dāng)注塑件的預(yù)制件較厚時，模殼溫度較高；未空出水壓試驗(yàn)殘余量，則造成收攏，注塑加工或是相符合裝止逆環(huán)的環(huán)氧樹脂膠未運(yùn)用止逆環(huán)等小錯誤也時有一定的原因。
Generally speaking, when the thickness is greater than 5mm, the injection molded parts are easy to collapse; When the preform of the injection molded part is thick, the mold shell temperature is higher; Failure to empty the residual quantity of hydrostatic test will lead to small errors such as closing, injection molding or failure to use the check ring for the epoxy resin glue that is consistent with the installation of the check ring.
預(yù)制件的厚部與薄部（邊緣內(nèi)側(cè)等）的接合點(diǎn)采用注塑成型。注塑件較薄的部分先冷卻，較厚的部分被拉向內(nèi)側(cè)，導(dǎo)致注塑件表面出現(xiàn)麻點(diǎn)。
The joint between the thick part and the thin part (inside the edge, etc.) of the preform is injection molded. The thinner part of the injection molded part is cooled first, and the thicker part is pulled to the inside, resulting in pitting on the surface of the injection molded part.
注塑加工，特別是在初始生產(chǎn)過程中，會產(chǎn)生各種困難，收貨只是其中之一。因此，在注塑的整個過程中，注塑項(xiàng)目工程師必須立即對產(chǎn)品生產(chǎn)全過程的細(xì)節(jié)進(jìn)行測試，以防止出現(xiàn)大量不合格的注塑件。
Injection molding, especially in the initial production process, will produce various difficulties, and receiving is only one of them. Therefore, in the whole process of injection molding, the injection molding project engineer must immediately test the details of the whole process of product production to prevent a large number of unqualified injection molding parts.
此外，注塑制品具有重量輕、抗壓強(qiáng)度高、延展性好、耐腐蝕、絕緣性能好、易著色、易成型、成本低等優(yōu)點(diǎn)。因此，它們得到了廣泛的應(yīng)用和大家的青睞。
In addition, injection molded products have the advantages of light weight, high compressive strength, good ductility, corrosion resistance, good insulation, easy coloring, easy molding and low cost. Therefore, they have been widely used and favored by everyone.
由于注塑模具的應(yīng)用領(lǐng)域很大，主要用途不同，分類也比較復(fù)雜。按成型特性可分為熱固性塑料注塑模具和熱固性注塑模具。按成型工藝可分為傳遞模、注射模、澆注模、熱成型模、壓縮模和注射模。
Because the application field of injection mold is very large, the main uses are different, and the classification is also more complex. According to the molding characteristics, it can be divided into thermosetting plastic injection mold and thermosetting injection mold. According to the molding process, it can be divided into transfer mold, injection mold, pouring mold, thermoforming mold, compression mold and injection mold.
現(xiàn)階段，
濟(jì)南注塑加工人員提醒大家，如今市場上一些模具廠家的經(jīng)營規(guī)模不是很大，其成品質(zhì)量無法保證。所以大多數(shù)客戶不知道注塑模具的優(yōu)缺點(diǎn)，經(jīng)常會出現(xiàn)比較的情況，造成生產(chǎn)中的事故，所以在選擇廠家的時候也要注意。
At this stage, Jinan injection molding processing personnel remind you that the business scale of some mold manufacturers in the market is not very large, and the quality of their finished products cannot be guaranteed. Therefore, most customers do not know the advantages and disadvantages of injection molds, and there are often comparative situations, resulting in accidents in production, so they should also pay attention to when selecting manufacturers.
