How to use luminous powder in injection molding

1. Special luminous powder for injection molding is suitable for various performance rubber materials (PP, ABS, PC, PVC, etc.). It has better luminous effect with transparent plastic, and translucent plastic can also apply better luminous effect. To color, do not add too much toner in the rubber compound, otherwise it will greatly reduce the brightness of the night light. The color of the dark product should have a good night light brightness to increase the proportion of the luminous powder; the fluorescent color luminous powder can be directly transparent. The rubber compound is mixed, no need to add color powder;

     2, the proportion of fluorescent luminous powder: plastic material: luminous powder = 1 kg: 20 g ~ 200 g, in this range, the more the amount of luminous powder is brighter, the addition amount is too small, the dispersion is uneven, resulting in product illumination The effect is not so good; specifically according to customer requirements.

     3, rubber material selection: water mouth material plus luminous powder injection is easy to black, it is recommended to use new materials; the rubber in the rubber is also easy to black, so moderate drying before injection;

     4, injection molding machine selection: injection molding machine to be clean, use a short barrel, reduce injection time, fast forward and fast, so as not to burn black; one minute, the effect of different injection molding machine is also different, if injection molding luminous If the product is unsuccessful, the injection molding machine can be adjusted to have good results;

     5, mixing method: add appropriate amount of white mineral oil and rubber compound to mix evenly (white mineral oil viscosity to avoid the night light powder sinking bottom), and then add the luminous powder according to the proportion of mixing, you can, (remember to avoid using metal items to stir vigorously, otherwise It will turn black) (try to reduce the injection temperature, reduce the temperature of the product molding, avoid blackening of the night light products), and become a luminous plastic product after injection molding.

     I have already introduced how to solve the blackening phenomenon of luminous powder in the injection molding process. Today is the use of luminous powder in injection molding. The application of luminous powder in life is extensive, and the ultrafine particles of luminous materials are incorporated into textiles. To make the color more vivid, children can wear textiles with luminous light to reduce traffic accidents.
