A phonograph record pressed from a master mold or matrix. disc, of mother-of-pearl ( excl. button blanks) 唱片从唱片模板或母带压制出来的唱片珍珠母制圆片(不包括纽扣坯料)
It expounded based on experiment, the whole manufacturing process of fiberglass-reinforced plastic ( FRP) mold with the aid of rapid prototype or master mold. 根据实际制作经验,详细地阐述了以RP原型(快速原型)为母模快速翻制玻璃钢模具的制造工艺及其相关细节;
A master mold is robust and can be used to produce a large number of production molds. 如果原模坚固,就可以用来生产较多的生产模具。
If a production mold is made from a master mold that is made from the master model, it is a second generation production mold. 若生产模具来自原模制成的原模,那么这个生产模具就是第二代生产模具。
RP based mould making process with plaster casting technique firstly uses rapid prototype as master mold, then get gypsum mould through silicone rubber mould, lastly become the final metal mould using plaster precision casting technology. 本文指出,基于快速成形技术的石膏型快速模具制造技术是以快速原型为母模,通过硅胶模转制技术得到石膏型,最后采用石膏型精密铸造的方法获得最终模具。
The open practice can consolidate the students ′ theoretical basic knowledge and train them master main skill in geography, then develop their intelligence and mold their sentiments of patriotism. 野外实习可以巩固学生的基础理论知识,培养学生掌握地理方面的基本技能,发展学生的智力并能陶冶学生的爱国主义情操。
