在注塑过程中，由于多种因素，注塑件出现收拢或部分收拢，对产品的损坏是的。什么情况下容易出现这种收拢状态呢？

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?

一般来说，当厚度大于5mm时，注塑件容易收拢；当注塑件的预制件较厚时，模壳温度较高；未空出水压试验残余量，则造成收拢，注塑加工或是相符合装止逆环的环氧树脂胶未运用止逆环等小错误也时有一定的原因。

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.

预制件的厚部与薄部（边缘内侧等）的接合点采用注塑成型。注塑件较薄的部分先冷却，较厚的部分被拉向内侧，导致注塑件表面出现麻点。

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，特别是在初始生产过程中，会产生各种困难，收货只是其中之一。因此，在注塑的整个过程中，注塑项目工程师必须立即对产品生产全过程的细节进行测试，以防止出现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，注塑制品具有重量轻、抗压强度高、延展性好、耐腐蚀、绝缘性能好、易着色、易成型、成本低等优点。因此，它们得到了广泛的应用和大家的青睐。

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.

由于注塑模具的应用领域很大，主要用途不同，分类也比较复杂。按成型特性可分为热固性塑料注塑模具和热固性注塑模具。按成型工艺可分为传递模、注射模、浇注模、热成型模、压缩模和注射模。

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.

现阶段，济南注塑加工人员提醒大家，如今市场上一些模具厂家的经营规模不是很大，其成品质量无法保证。所以大多数客户不知道注塑模具的优缺点，经常会出现比较的情况，造成生产中的事故，所以在选择厂家的时候也要注意。

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.
