Silicone rubber mixing process
Because the silicone elastomer keypad color is too much, then the rubber refining needs to separate the rubber material of each color, and match the color according to the color card and process standards, and ensure that there is no color difference.
Oil pressing is an important factor to determine the quality of multi-color silicone elastomer keypad.
First of all, it is necessary to accurately swing the material according to the structure of the mold and silicone rubber button pad to ensure that there is no deviation so as not to cause the color mixing of keys.
At the same time, you can also use multi-color single K molding and then silicone for secondary vulcanization molding, which can greatly reduce the phenomenon of color, and color mixing.
The impurity problem of multi-color molding silicone keys can not be underestimated, it is necessary to ensure that the cleaning work of the molding link is normal, and strict operation in accordance with the product specifications and standards.
