| 塑料模具压制过程中，多余的塑料很容易顺着挤压边溢出，极易出现制件的水平飞边且很难去除。模具闭合速度快，导致原料的溢出量增加，因此，利用这类模具压制出来的塑料制品密度和强度不高，浪费的材料较多。但是敞开式塑料模具结构相对简单，适用性强而且低成本。制件易拿出，如果是压制扁平类制件，就可以免去推出机构的设置。 During the pressing process of plastic moulds, excess plastics easily overflow along the extrusion edge, and it is very easy to produce horizontal flying edges of parts and it is difficult to remove them. The quick closing speed of the mould leads to the increase of the overflow of raw materials. Therefore, the density www.zhijia.org.cnwww.zhidiaojia.org.cnwww.qibijizhamen.com.cnwww.juanyangqibij.cn www.qingwuji.net.cnwww.yasiban.cnand strength of the plastic products pressed by this kind of mould are not high, and there are many wasted materials. However, the structure of the open plastic mould is relatively simple, the applicability is strong and the cost is low. The parts are easy to take out. If the flat parts are pressed, the setting of the pushing mechanism can be avoided. |
