山東注塑加工中的塑料制品在我們的生活中很常見(jiàn)，使用塑料外殼的產(chǎn)品更是多得數(shù)不勝數(shù)。塑料外殼加工的方式與普通塑料制品的加工原理是一樣的，但在要求上還是有一些不同的。下面我們便來(lái)簡(jiǎn)單介紹下塑料外殼加工的散熱問(wèn)題。Plastic injection molding process in Shandong is very common in our lives, the use of plastic housing products are numerous. Plastic shell processing and ordinary plastic products processing principle is the same, but there are still some different requirements. Here we will briefly introduce the plastic shell processing of heat dissipation.

在山東注塑加工的注塑外殼加工過(guò)程中熱量的散失是一個(gè)必須要考慮的一個(gè)重要方面，通常熱量的散失是由于其傳遞的不間斷性造成的。在注塑生產(chǎn)之時(shí)熱的傳遞方式主要有輻射、對(duì)流和傳導(dǎo)三種，除了大部分被模具吸收之外，還有一部分是通過(guò)輻射、對(duì)流的方式散發(fā)到空氣之中的。The heat dissipation is an important aspect to be considered in the injection molding process of plastic injection molding in Shandong, and the loss of heat is usually due to the continuity of the transmission. In the injection molding of the heat transfer mode is mainly radiation, convection and conduction three, in addition to most of the absorption by the mold, but also part of the way through the radiation, convection into the air.

山東注塑加工廠家認(rèn)為，在塑料外殼加工成型的時(shí)候需要提高熱量的利用率，而在成型冷卻的時(shí)候，則需要較快的降低溫度，這個(gè)就需要冷卻模具上戰(zhàn)場(chǎng)了，通常冷卻采用的介質(zhì)是水，緣由是水價(jià)格低，成本自然也就低，冷卻過(guò)后的水源可以循環(huán)利用。但是畢竟凡事都有利有弊，低價(jià)格與可循選使得其只能作為初級(jí)冷卻劑來(lái)使。Shandong plastic processing factory, when the plastic shell molding process to improve the utilization rate of the heat, and when the molding requires cooling, temperature decreases quickly, this requires cooling die on the battlefield, usually by the cooling medium is water, the reason is the price of water is low, the cost is naturally low, cooling after the water can be recycled. But after all, everything is low price and choose to follow There are both advantages and disadvantages., makes it only as a primary coolant to.

山東注塑加工廠家提醒，如果想要達(dá)到最佳冷卻效果還是需要冷模上場(chǎng)的，在這里需要特別提醒的一點(diǎn)是并不是冷卻劑越冷越好，物極必反，過(guò)冷可能會(huì)出現(xiàn)反效果。Shandong plastic processing factory to remind, if you want to achieve the best cooling effect still need cold play, here needs to point to remind the coolant is not as cold as possible, however, too cold may cause negative effects.
