工程设计阶段: ? ?主要是完成整车各总成及零部件的设计，协调各总成之间以及总成与整车之间的矛盾。因为新车有超过2万个零部件，很多零件都没有开模生产。因此原来的测试零部件和总成产品都是通过CNC加工和钣金制作出来的。首先CNC加工样件的表面效果和精度同样跟编程人员的技术有很大关系，其次对一些造型复杂，加工面多的工件需要用到五轴加工中心，加工成本高昂甚至没有办法加工到位。 In the engineering design phase: Mainly to complete the design of the complete assembly and parts of the vehicle, coordinate the contradiction between the assemblies and between the assembly and the vehicle. Because the new car has more than 20,000 parts, many parts are not produced. Therefore, the original test parts and assembly products were produced by CNC machining and sheet metal. First of all, the surface effect and precision of the CNC machining sample are also closely related to the programmer's technology. Secondly, for some complex shapes, the workpiece with many machining surfaces needs to use a five-axis machining center, and the processing cost is high or even no way to process it.
金石三维将3D打印与真空成型（低压灌注）工艺结合，形成了快速模具制造方法。首先使用高精度的3d打印设备制作产品原型，然后在管压真空状态下制作出硅胶模具，并在低压真空状态下来用PU材科进行浇注，从而克隆出与产品原型相同的件。金石复模制造部门采用进口PU树脂，制造出性能可以媲美注塑加工成品的样件，可以替代ABS、PC、橡胶等材质的零部件。既保证了精度，又降低了成本，大大提高生产效率！ Jinshi 3D combines 3D printing with vacuum forming (low pressure infusion) to form a rapid mold manufacturing method. First, a high-precision 3D printing device was used to make a prototype of the product, and then a silicone mold was produced under vacuum pressure, and the PU material was poured under a low pressure vacuum state to clone the same replica as the prototype. Jinshi Duplicate Manufacturing Department adopts imported PU resin to produce samples with performance comparable to those of injection molding, which can replace ABS, PC, rubber and other materials. It not only ensures the accuracy, but also reduces the cost and greatly improves the production efficiency!
例：汽车前格栅、曲面结构非常多，这种全网格化的复杂造型传统机床加工是非常困难的，而通过将这些复杂的局部零部件3D打印之后再镶嵌进整车模型中，可以达到理想的效果。 For example: the front grille and curved surface structure of the car are very many. This kind of full meshing complex modeling is very difficult to process traditional machine tools, and by embedding these complicated partial parts in 3D and then embedding them into the whole vehicle model, Achieve the desired results.
