塑胶模具爆裂是注塑件加工厂家比较经常发生的一个质量问题，这个性质是非常严重，那主要是怎么形成的呢？

Plastic mold burst is a quality problem that often occurs in injection molding manufacturers. This property is very serious. How is it mainly formed?

轻按一下就有爆裂的这种情况。该位置主要是粘合线，即注塑模具加工厂在设计胶合点时未将其设计在适当的位置，而是在焊缝的顶部形成了凸点。这也取决于外面较薄的位置。特别是在ABS材料的生产中，很容易折断。经验丰富的设计工程师将首先检查胶水入口点，然后将注塑模具焊缝驱动到不会破裂的位置。

There is a burst at the touch of a button. This position is mainly the bonding line, that is, the injection mold processing plant did not design the bonding point in the appropriate position, but formed a convex point on the top of the weld. It also depends on the thinner location outside. Especially in the production of ABS materials, it is easy to break. Experienced design engineers will first check the glue entry point and then drive the injection mold weld to a position where it will not crack.

注塑加工厂的注塑人员离职超过20分钟。当他们重新就岗时，他们没有将掉在桶里太久的废胶扔掉，并导致橡胶变质。如果直接生产，也会引起爆裂。在这种情况下，更难以分析质量。

The injection molding personnel in the injection molding processing plant left their jobs for more than 20 minutes. When they returned to their posts, they did not throw away the waste rubber that had fallen in the bucket for too long, which led to the deterioration of the rubber. If it is produced directly, it will also cause burst. In this case, it is more difficult to analyze the quality.

注塑模具原料有太多的塑料挥发物，太多的湿度，太多的杂质，太多的回收材料以及受污染的注塑模具也可能会破裂。解决方案：1.清洁喷嘴，防止流向，并且浇口可能被阻塞；2.严格按照喷嘴材料的比例添加；3.将焊缝驱动到不会破裂的位置；4。暂停中间，暂停后，清除先前的废料，然后生产新的注塑模具。5.筛分废料，杂质等。

Injection mold raw materials have too many plastic volatiles, too much humidity, too many impurities, too many recycled materials and contaminated injection molds may also break. Solution: 1 Clean the nozzle to prevent flow direction, and the gate may be blocked; 2. Add in strict accordance with the proportion of nozzle material; 3. Drive the weld to a position where it will not crack; 4。 Pause in the middle, after the pause, remove the previous waste, and then produce a new injection mold. 5. Screen waste, impurities, etc.

山东模具制造厂家认为加工时的注意事项要知道，比如在模具方面，精密模具加工设备的微注塑成型远高于传统的注塑模具成型：在模具加工中，注塑模具加工一般有两种趋势：一是采用镜面火花加工，以保证高精度模具加工。

Shandong mold manufacturers believe that the precautions in processing should be known. For example, in terms of molds, the micro injection molding of precision mold processing equipment is much higher than the traditional injection mold molding: in mold processing, there are generally two trends in injection mold processing: one is to adopt mirror flame processing to ensure high-precision mold processing.

为了精度，电火花加工应使用石墨电极，因为石墨电极的损耗远小于一般铜电极。与普通加工方法相比，另一种替代方法是使用电涂抹，选择电成型技术以确保非常高的精度，但缺点是加工周期长，每个点都需要注塑成型，并且损伤较小生产，无法纠正，只能更换损坏的模具。

In order to improve the accuracy, graphite electrode should be used in EDM, because the loss of graphite electrode is much less than that of general copper electrode. Compared with ordinary processing methods, another alternative method is to use electric coating and select electric forming technology to ensure very high accuracy, but the disadvantage is that the processing cycle is long, each point needs injection molding, and the damage is small, which can not be corrected. Only the damaged mold can be replaced.

注塑成型时，可提前模具温度（可超过所用塑料的熔点），使熔体快速完成型腔，避免充模过程中温度下降。填充太快且不完整；取出时，模具温度会下降，保持略低于塑料热变形温度，然后开顶。另外，由于微注塑的质量是千年材料产品。只要少于10%的材料被注入到注塑产品中，有很多铸造系统，因此可以选择一个注塑模具来使用该铸造系统。

During injection molding, the mold temperature can be advanced (which can exceed the melting point of the plastic used), so that the melt can quickly complete the mold cavity and avoid the temperature drop during mold filling. Filling too fast and incomplete; When taking out, the mold temperature will drop, keep it slightly lower than the plastic thermal deformation temperature, and then open the top. In addition, because the quality of micro injection molding is Millennium material products. As long as less than 10% of the material is injected into the injection molded products, there are many casting systems, so you can choose an injection mold to use the casting system.

塑胶模具加工生产时出现爆裂的原因便是以上讲解了，所以为了注塑模具的质量问题以及人员的安全，加工期间还是要多注意事项，更多内容可以来网站www.sdlqmj.com咨询。
