摘要
基于3D打印快速成型技术低成本、快速获取、按需生产的特点,提出了一种将3D打印线缆连接器作为医疗器械线缆连接器注射成型中间媒介的新应用。将3D打印的预成型零件,替代真实线缆连接器进行二次注射成型过程中的工艺参数摸索与调试,待注塑参数确定后再使用真实零件进行生产。以某线缆连接器为例,设计了用于二次注射成型参数调整的3D打印零件,选用3D打印用塑料制作了预成型零件并进行了线缆连接器内部芯模注射成型和外部包胶注射成型的注塑试验。对比发现,3D打印零件可以复现真实线缆连接器的注射成型效果和被注塑材料用量,材料成本大幅降低,同时大幅减少了样品制备周期,为3D打印技术在医疗器材及线缆连接器制造领域的应用提供了新思路。
A novel application of the 3D-printing rapid prototyping technology,i.e.,using it as an intermedia of the injection molding,on the manufacture of medical equipment cable connectors was proposed based on its advantages of low cost,and rapid and on-demand productions.The 3D-printed components are applied to explore the proper molding parameters of the secondary forming process as a replacement of the real cable connectors,and the real components can be used only after all the process parameters are determined.A 3D-printed cable connector was designed and manufactured using plastic material.The pre-molding and over-molding tests with 3D-printed components were processed.The results show that the molding results using 3D-printed parts are similar to those with the real cable connectors under different process parameters in the aspects of the exterior of connectors after molding as well as the amount of material used.The 3D-printed parts contributes to reducing the material cost as well as the sample preparation cycle.This study provides a new approach to 3D-printing technology in the field of medical equipments and cable connectors manufacturing.
