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.
塑料模具加工工艺现状
Present situation of plastic mold processing technology
1）气体辅助成型技术日趋成熟
1) Gas assisted molding technology is becoming more and more mature
近几年，气体辅助成型技术在塑料模具加工中逐渐得到应用。目前，已经有部分企业将气体辅助成型技术应用在洗衣机外壳、电视机外壳以及汽车装饰物件等塑料物件加工工艺中，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）热流道技术应用广泛
2) Hot runner technology is widely used
虽然热流道塑料模具应用所占比例不高，但是热流道技术在塑料模具加工行业中的发展速度非常快，目前，热流道技术在塑料模具加工工艺中的应用率已经达到了33.33%。比较常见的热流道加工技术分为三种，分别是一般内热式、分流板式以及外热式。
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
随着新技术、新工艺的不断引进，塑料模具的使用寿命得到延长。目前，我国高速塑料异型材的加工速度已经达到了商业化加工速度。塑料异型材的基础模式可分为双腔共挤以及多腔共挤两种模式。我国有较多的企业已经在塑料模具加工过程中，精心设计自动脱流道模进而冷却系统，这令塑料模具加工效率得到了显著的提高。
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.
