塑膠模具爆裂是（shì）注塑件加工廠家比（bǐ）較經常發生的一（yī）個質量問題，這個性質是非常嚴重（chóng），那主要是怎麽形成（chéng）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?

輕按一下（xià）就有爆裂的這種情況。該位置主要是粘合線，即注塑模具加工廠在設計膠合點時未將其設計（jì）在適當的位置，而是在焊縫的頂部形成了凸點。這也取決於（yú）外麵較薄的（de）位置。特別是在ABS材料的（de）生產（chǎn）中，很容易折斷。經驗豐富的設計（jì）工程師將首先檢查膠水入口點，然後將注塑模具焊縫驅動到不會破裂的位置。

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 locations 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.

注塑加工廠的注塑人員離職超過20分鍾。當他們重新就崗時，他們沒（méi）有（yǒu）將掉在桶裏太久的廢（fèi）膠扔掉，並導致（zhì）橡膠（jiāo）變質。如果直接生產，也會（huì）引起爆裂。在（zài）這種情（qíng）況（kuàng）下，更難以分析質量。

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（zhù）塑模具原料有太多的塑料（liào）揮（huī）發物，太多的濕度，太多的雜質，太多（duō）的回收材料以及受汙染（rǎn）的注塑模具也可能會破裂。解決方（fāng）案：1.清潔噴嘴，防止（zhǐ）流向，並且澆口可能被阻塞；2.嚴格按照噴嘴材料的比例添加；3.將焊縫驅動到不會破裂的（de）位置；4。暫停中間，暫停後，清除（chú）先前的廢料，然後生產（chǎn）新（xīn）的注塑模具。5.篩分廢料（liào），雜（zá）質等。

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.

山東模具製造廠家認（rèn）為加工時的注意事項要知道，比如在模（mó）具方麵，精密（mì）模具加工（gōng）設備的微注塑成型遠高於傳統（tǒng）的注塑模具成型：在模具加工中，注塑模具加工一般有兩種趨勢：一是采用鏡麵（miàn）火花加工，以保證高精度模具加工。

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.

為了精度，電（diàn）火花加工應使用石墨電極，因（yīn）為石墨電極的損耗（hào）遠小於一般銅電極。與（yǔ）普通加工方法相比（bǐ），另（lìng）一種替代方法是（shì）使用（yòng）電塗抹，選擇電成型技術以確保（bǎo）非常高的精度，但缺點是加工周期長，每個（gè）點都需要注塑成型，並且損傷較小生產，無法糾正，隻能更換損壞的模具。

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（sù）成型時，可提前模具溫度（可（kě）超過所用塑料（liào）的熔點），使（shǐ）熔體快速完成型腔，避免充模（mó）過程中溫度下降。填充太（tài）快（kuài）且不完整；取出時，模具溫度會下降，保持略低於塑料熱變形溫度，然後開頂。另外，由（yóu）於微注塑的質量是千年材料產品。隻要少於10%的（de）材料被注入到注塑產品中，有很多鑄造係統，因此（cǐ）可以選（xuǎn）擇一個注塑模具來使用該鑄造係統。

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.

塑膠模具（jù）加工（gōng）生產時出現爆裂的原因便是以上講解了，所以為了注塑模具（jù）的質量問題以及（jí）人員的安全，加工期間還是要多注意（yì）事項，更多內容可以來網站www.lsjtcyjt.cn谘詢。
