减小SolidWorks文件大小的方法和Unfrag下载
2007-05-22 01:54:00
在互联网应用愈来愈广泛的时代,人们在互联网上的交流也越来越频繁。设计人员之间可以通过互联网传递设计文件来交流设计经验,增进设计水平;公司也可以直接将设计文件传递给加工制造公司,使他们可以在最短的时间内完成产品零部件的生产制造。而在文件传递的过程中,人们不得不面临着这样的问题:如何才能在保证文件正确无误的前提下,尽量压缩文件大小,从而迅速地发送和接收。我们在使用SolidWorks 的过程中发现,在利用压缩软件(Winzip,WinRar等软件)前,可以通过不同的方法减小SolidWorks 的文...


PA6与PA66的区别
2007-05-29 04:03:03
PA6的化学物理特性和PA66很相似,然而,它的熔点较低,而且工艺温度范围很宽。它的抗冲击性和抗溶解性比PA66要好,但吸湿性也更强。因为塑件的许多品质特性都要受到吸湿性的影响,因此使用PA6设计产品时要充分考虑到这一点。为了提高PA6的机械特性,经常加入各种各样的改性剂。玻璃就是最常见的添加剂,有时为了提高抗冲击性还加入合成橡胶,如EPDM和SBR等。对于没有添加剂的产品,PA6的收缩率在1%到1.5%之间。加入玻璃纤维添加剂可以使收缩率降低到0.3%(但和流程相垂直的方向还要稍高一些)。成型...


IMD(模内转印)工艺详解
