Note on the use of glow powder in production of plastic injection luminous toys

Glow-in-the-dark toy is a light-emitting instrument for children to play with, and its colors are also colorful. In fact, glow-in-the-dark toys are made use of injection molding of glow-in-the-dark powder, so that toys emit beautiful light at night, then what matters needing attention in injection molding method of glow-in-the-dark toys glow-in-the-dark powder? The following small series to introduce you.

1, ingredients: proportional scale first ChuGuang suction light emitting noctilucent powder (content accounts for about 2 ~ 10%), the spread of adding small amounts of oil (paraffin oil, white oil) expanding mix into a paste and adding raw materials mixing, add toner stir, stir well, time shoulds not be too long to avoid long persistence luminescent powder deposition, pay attention to yao DE SAN technology noctilucent powder avoid friction with heavy metals such as iron, can make the raw material. The material can be used: PP, PE, PVC, PU, PS, ABS, TPR, EVA, PMMA, nylon and so on. The more transparent the plastic material, the better the luminous effect, as far as possible with fluorescent toner, add the less the better.

2, the temperature of the injection molding machine can be lowered, and the time of the material in the injection molding machine should not be too long, so as not to burn.

3, injection molding machine: different machines injection molding products, there are differences, new machines and old machines, domestic machines and imported machines, which need to be slowly debugging to solve.

4, luminous powder: luminous powder in injection molding due to various reasons, injection molding technology, injection molding machine, may cause blackening, according to their own experimental determination.

The above is about luminous toys luminous powder in injection molding need to pay attention to matters, I hope to help you.
