The reasons and elimination of tiny pits on the bright plastic parts surface

When pitting occurs, it is easy to think about whether the mold is rusty. However, upon closer inspection, it was found that the mold was still quite bright and there were no small marks.

After increasing the melt temperature and back pressure to improve the quality of the melt, the situation will improve, but sometimes it is still difficult to completely remove the pitting.

In fact, this is the reason why the toner has not completely melted. Because the surface of the mold cavity is too smooth and bright, the injection molded part is also very bright, and the small unmelted toner particles will be faithfully reflected on the surface of the injection molded part.

Therefore, the color is used to match the color, and the pits automatically disappear, and the surface of the injection molded part is as bright as a mirror.

In actual production, it is found that the proportion of black injection molded parts is relatively high. Therefore, when there are pitting problems on the bright surface parts, you may wish to consider the toner problem.
