The reason for the poor gloss of the surface of the injection molded product and the solution result in poor gloss on the surface of the injection molding, there are two main reasons for the overall transparency. First, the mold surface is not polished well, and the second is that the melt is cooled prematurely. The specific solution is as follows:
(1) Increase the material temperature, injection pressure and speed, especially the mold temperature. The mold temperature has a significant effect on the gloss.
(2) Improve the position of the gate and pay attention to the smooth flow of the material.
(3) Prevent the degradation or plasticization of plastics from being incomplete.
(4) The growth time in the mold is increased, and the holding time should be lengthened.
(5) Prevent gas interference. Http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn
