Method of injection molding of luminous powder in toys

Some time ago, when the weather was still very hot, I slid around the square in the community every night. There are many children’s toys that are especially eye-catching. They are colorful toys that can be illuminated. In fact, they use the injection of colored luminous powder. Toys emit beautiful light at night, let's take a look at the luminous toy injection method.

    1. Ingredients: firstly scale the light-absorbing light-emitting luminous powder (content is about 2 to 10%), add a small amount of diffusion oil (paraffin oil, white oil) and stir into a paste, then add the raw material to stir, then add Stir the toner, stir evenly, the time should not be too long to avoid precipitation of long afterglow luminous powder, pay attention to the luminous powder rubbing with heavy metals such as iron, which will make the raw materials black. The materials that can be used are: PP, PE, PVC, PU, PS, ABS, TPR, EVA, PMMA, nylon, etc. The more transparent the plastic material, the better the illuminating effect. The toner should be as fluorescent powder as possible. The less the better, the better.

    2. The temperature of the injection molding machine is lowered, and it can be injected. The time in the injection molding machine should not be too long to avoid burning.

    3. Injection Molding Machine: There are also differences in the products injected from different machines. New machines and old machines, domestic machines and imported machines, all need to be solved slowly.

    4. Luminous powder: Luminous powder in the injection molding for various reasons, injection molding technology, injection molding machine, may cause blackening, can be determined according to their own circumstances.
