⑴使用寿命：在确保制品质量的前提下，模具所能完成的工作循环次数或生产的制件数量。
(1) service life: the number of work cycles that can be completed by the mold or the number of parts produced on the premise of ensuring the product quality.
⑵制品质量：制品尺寸的稳定性，符合性，制品表面的光洁度，制品材料的利用率等等。
(2) product quality: stability and conformity of product size, smoothness of product surface, utilization rate of product materials, etc.
⑶模具的使用维护：是否属方便使用，脱模容易，生产辅助时间尽可能的短。
(3) use and maintenance of mold: whether it is convenient to use, easy to demould, and the production auxiliary time shall be as short as possible.
提高塑胶模具厂质量的基本途径：模具的设计是提高模具质量的重要的一步，需要考虑到很多因素，包括模具材料的选用，模具结构的可使用性及安全性，塑胶模具厂的制造过程也是确保模具质量的重要一环，模具制造过程中的加工方法和加工精度也会影响到模具的使用寿命，对模具主要注塑模具成形零部件进行表面强化，以提高模具零件表面耐磨性，从而更好地提高模具质量，模具的正确使用与维护，也是提高模具质量的一大因素。
Basic ways to improve the quality of plastic mold factory: mold design is an important step to improve mold quality. Many factors need to be considered, including the selection of mold materials, the usability and safety of mold structure. The manufacturing process of plastic mold factory is also an important part to ensure mold quality, The processing method and accuracy in the mold manufacturing process will also affect the service life of the mold. The surface strengthening of the main injection mold forming parts of the mold is carried out to improve the surface wear resistance of the mold parts, so as to better improve the mold quality. The correct use and maintenance of the mold is also a major factor to improve the mold quality.
例如：模具的安装调试方式应恰当，在有热流道的情况下，电源接线要正确，冷却水路要满足设计要求，模具在生产中注塑机，压铸机，压力机的参数需与设计要求相符合等等。
For example, the installation and commissioning mode of the mold should be appropriate. In the case of hot runner, the power wiring should be correct, the cooling water path should meet the design requirements, and the parameters of injection molding machine, die casting machine and press should meet the design requirements in the production of the mold.
在包装行业，注塑工艺越来越受到人们的重视，其原因在于人们使用了多层模具，这是热流道技术上的一个进步，通过采用薄壁注塑工艺，能节省原材料的费用，其他特殊工艺例如压模标记法和多组分技术，也为减少工艺步骤，提高产量和提高 效益起到了积极的作用。
In the packaging industry, people pay more and more attention to the injection molding process. The reason is that people use multi-layer molds, which is a progress in hot runner technology. The cost of raw materials can be saved by using thin-wall injection molding process. Other special processes, such as die marking method and multi-component technology, also reduce the process steps, It has played a positive role in increasing output and efficiency.
塑料包装材料，特别是在食品工业领域，由于其重量轻和耐用性好的特点，为提高我们今天的生活水平作出了很大的贡献，另外，要把大工业化生产出来的产品配送到世界各地，如果没有包装材料的话，那也是难以想象的，所以从整体上看，在过去的几年里整个塑料包装市场，主要是深拉包装塑料薄膜得到了快速增长，其中，注塑加工注塑包装材料，如包装箱或杯子，正处于上升阶段，并逐渐取代热成型包装材料。
Plastic packaging materials, especially in the field of food industry, have made great contributions to improving our living standards today because of their light weight and good durability. In addition, it is unimaginable to distribute the products produced by large-scale industrialization to all parts of the world without packaging materials, so on the whole, In the past few years, the whole plastic packaging market, mainly deep drawing packaging plastic film, has grown rapidly. Among them, injection molding packaging materials, such as packaging boxes or cups, are in the rising stage and gradually replace thermoforming packaging materials.
