The artifact of brightening plastic products

Injection molding process is one of many plastic products. They have an important standard in production. That is, the brightness and glossiness of plastic injection appearance, which is an important factor in determining the sales volume of products. To achieve a better appearance, we need to choose the right brightener, so as to fundamentally solve the problem of brightening injection molding products.

 

Plastic injection molding is a kind of production molding process. Plastic injection can be divided into rubber injection molding, plastic injection molding and molding injection molding. Each of them has excellent quality. The former has simple production process, high production efficiency, small labor force, excellent product quality, and the latter has stronger plasticity. The plastic which is hot melt in advance will be injected into plastic products mold by pressure injection, and cooled into various plastic products, The raw materials are PE and PP.

 

Nowadays, with the increasing demand of plastic products in the market, the quality of products made by manufacturers is very different due to the difference of raw materials, process and formula. The brightener is a kind of assistant which can greatly improve the brightness of plastic products and improve the competitiveness of products in the market, How to achieve the mirror effect of plastic injection molding, the general method is to use some lubricants, plasticizers to increase the fluidity of products, but there is no good effect, let alone achieve the ideal requirements of injection molding manufacturers mirror like brightness.

 

There are some manufacturers who produce ABS injection molding, and their injection temperature and melting viscosity are different from other amorphous plastics. When the melting temperature increases, the plasticizing temperature can reach 220-250 ℃, so the injection temperature of ABS is higher than that of polystyrene and other plastics. The requirements for ABS injection brightener are also very high. It is necessary to select the ABS plastic brightener which can resist high temperature.

 

The method of adding brightener is very simple. In the process of production, only mixing and mixing with raw materials according to a certain amount of additives is required. It is necessary to note that the proportion of adding one ton of raw materials is recommended to add 1-3kg. If the material is returned, it can be added to 3-5kg. Many customers dare not increase the amount of products in order to control the cost during commissioning, and give up the products before they have the brightening effect. This is certainly not possible. The correct method is to start with 5% of the amount of the product before debugging, and then reduce the dosage slowly after the obvious brightening effect is achieved, so that the effect of this brightener can be exerted.
