At present, the proportion of plastic mold manufacturing in the whole mold industry is as high as 30%. It can be seen that the plastic mold processing technology is of great significance. At this stage, plastic molds have been used in aerospace, instrument electromechanical and automobile manufacturing industries. Therefore, plastic mold processing technology has a very good development prospect. Next, the author analyzes the current situation of plastic mold processing technology and the future development trend of plastic mold processing technology.
塑料模具加工工藝現狀
Present situation of plastic mold processing technology
1）氣體輔助成型技術日趨成熟
1) Gas assisted molding technology is becoming more and more mature
近幾年，氣體輔助成型技術在塑料模具加工中逐漸得到應用。目前，已經有部分企業將氣體輔助成型技術應用在洗衣機外殼、電視機外殼以及汽車裝飾物件等塑料物件加工工藝中，并且取得了非常好的效果。
In recent years, gas assisted molding technology has been gradually applied in plastic mold processing. At present, some enterprises have applied gas assisted molding technology to the processing of plastic objects such as washing machine shell, TV shell and automobile decoration objects, and achieved very good results.
2）熱流道技術應用廣泛
2) Hot runner technology is widely used
雖然熱流道塑料模具應用所占比例不高，但是熱流道技術在塑料模具加工行業中的發展速度非?？?，目前，熱流道技術在塑料模具加工工藝中的應用率已經達到了33.33%。比較常見的熱流道加工技術分為三種，分別是一般內熱式、分流板式以及外熱式。
Although the application proportion of hot runner plastic mold is not high, the development speed of hot runner technology in plastic mold processing industry is very fast. At present, the application rate of hot runner technology in plastic mold processing technology has reached 33.33%. The common hot runner processing technologies are divided into three types: general internal heating type, shunt plate type and external heating type.
3）塑料模具效率得到提高
3) The efficiency of plastic mould is improved
隨著新技術、新工藝的不斷引進，塑料模具的使用壽命得到延長。目前，我國高速塑料異型材的加工速度已經達到了商業化加工速度。塑料異型材的基礎模式可分為雙腔共擠以及多腔共擠兩種模式。我國有較多的企業已經在塑料模具加工過程中，精心設計自動脫流道模進而冷卻系統，這令塑料模具加工效率得到了顯著的提高。
With the continuous introduction of new technologies and processes, the service life of plastic molds has been extended. At present, the processing speed of high-speed plastic profile in China has reached the commercial processing speed. The basic modes of plastic profile can be divided into two modes: double cavity coextrusion and multi cavity coextrusion. In the process of plastic mold processing, many enterprises in China have carefully designed the automatic runner mold and then the cooling system, which has significantly improved the processing efficiency of plastic mold.
