目前精密注塑机主要是国外品牌。目前，我国每年进口的约2万台塑机中，有60%是精密注塑机。在多层共挤塑机方面，我国的塑机在精确控制层厚技术上还难以与国外塑机相比。挤出装备中的双向拉伸PET(PA、BOPP)膜机组、精密医用导管挤出机组等也一直是国外公司的领地。开发具有自主知识产权的国产精密注塑和挤出装备非常必要，一方面可以替代进口，还可以使得我国在国际塑料机械高端市场上占据一席之地。
At present, precision injection molding machines are mainly foreign brands. At present, 60% of the 20000 plastic machines imported every year are precision injection molding machines. In the aspect of multi-layer coextrusion machine, it is difficult to compare the technology of precise layer thickness control in our country with that in foreign countries. Biaxially stretched pet (PA, BOPP) film units and precision medical catheter extrusion units in extrusion equipment have also been the territory of foreign companies. It is very necessary to develop domestic precision injection molding and extrusion equipment with independent intellectual property rights. On the one hand, it can replace the import, and also make our country occupy a place in the high-end market of international plastic machinery.
