沟盖板模具在生产时如何避免出现色差
控制原材料是彻底解决色差的关键。因此,尤其是生产浅色制品时,不能忽视原料树脂的热稳定性不同对制品色泽波动带来的明显影响。生产中常常会遇到因某个加热圈损坏失效或是加热控制部分失控长烧造成料筒温度剧烈变化从而产生色差。这类原因产生的色差很容易判定,一般加热圈损坏失效产生色差的同时会伴随着塑化不均现象,而加热控制部分失控长烧常伴随着产品气斑、严重变色甚至焦化现象。因此生产中需经常检查加热部分,发现加热部分损坏或失控时及时更换维修,以减少这类色差产生几率。
Controlling the raw materials is the key to solve the color difference thoroughly. Therefore, especially in the production of light colored products, the obvious influence of the different thermal stability of raw resin on the color fluctuation of products cannot be ignored. In production, it is often encountered that the temperature of the barrel changes dramatically due to the damage and failure of a heating ring or the long burning of the heating control part out of control, resulting in color difference. The color difference caused by this kind of reasons is easy to determine. Generally, the color difference caused by the damage and failure of heating ring will be accompanied by the uneven plasticization, while the out of control long burning of heating control part is often accompanied by the product gas spot, serious discoloration and even coking. Therefore, it is necessary to check the heating part frequently in production, and replace and repair the heating part in time if it is damaged or out of control, so as to reduce the probability of such color difference.
非色差原因需调整注塑工艺参数时,尽可能不改变注塑温度、背压、注塑周期及色母加入量,调整同时还需观察工艺参数改变对色泽的影响,如发现色差应及时调整。这些原因都是需要很多的经验才能避免,所以在生产注塑沟盖板模具的产品时还是需要工人们多多的掌握专业技术
When the injection molding process parameters need to be adjusted for non color difference reasons, the injection temperature, back pressure, injection cycle and the amount of Color Masterbatch should not be changed as much as possible. At the same time, the influence of the change of process parameters on the color should be observed. If the color difference is found, it should be adjusted in time. All of these reasons need a lot of experience to avoid, so it is still necessary for workers to master more professional skills in the production of injection groove cover mold products
