在光盘复制生产过程中,PC料(聚碳酸酯)在注塑模压机的料筒内加热成熔融状态,在螺杆的挤压下注射到模具的腔内。经冷却成形,形成光盘盘基。在这个过程中,注射的水口将被切除。我们知道,一张光盘的重量约16克,由于采用的模具不同,一张光盘的水口料重量在0.4-0.5克左右。在以前光盘复制厂把这部分水口料作为废料处理。随着市场竞争的日益激烈水口料的回收再利用已成为众多光盘复制厂节约成本的方法之一。水口料的回收再利用会不会影响复制光盘的质量? 确实,传统的离线式水口料集中回收利用系统因其需要人工收集水口料,集中粉碎容易
In the CD-ROM copy production process, PC material (polycarbonate) in the injection molding machine barrel heating into a molten state, under the extrusion of the screw into the cavity of the mold. After cooling forming, forming disc disc base. In this process, the injection nozzle will be cut off. We know that a disc weighs about 16 grams, due to the use of different molds, a disc outlet material weight of 0.4-0.5 grams. This part of the spout material was treated as scrap at a previous disc duplication plant. With the increasingly fierce market competition Shuikou materials recycling has become one of the many cost-saving methods of CD duplication plant. Does Recycling of Spout Material Affect the Quality of Copied Discs? Indeed, the traditional off-line spun-material recycling system requires manual collection of spout material and is easily shredded
