Causes and solutions of low brightness of ABS injection parts

In the process of injection molding, the problem of low brightness of ABS injection parts is often encountered. This not only affects the beauty of the product, but also has a certain impact on the performance. This paper will briefly analyze the reasons of low brightness of ABS injection parts, and introduce several solutions.

1. Reason analysis

1. Improper temperature: too high or too low barrel temperature, nozzle temperature or mold temperature may lead to low brightness of ABS injection parts.

2. Improper injection speed: Too fast or too slow injection speed may cause the material to not be fully filled, thus affecting the brightness.

3. Material moisture: ABS material has strong water absorption, moisture will lead to a decrease in brightness.

4. Mold problems: mold design and manufacturing defects, rust, etc., will lead to low brightness of injection parts.

Second, solutions

1. Control the temperature: reasonably adjust the temperature of the barrel, nozzle and mold to avoid overheating or undercooling.

2. Adjust the injection speed: Adjust the injection speed properly to ensure that the material is fully filled and avoid being too fast or too slow.

3. Dry material: Ensure that the material is dry and avoid the brightness decrease due to moisture.

4. Mold maintenance: Regular maintenance of the mold, eliminate manufacturing defects and rust, improve brightness.

5. Replace the nozzle: Choose the right nozzle, can improve the brightness of the injection parts.

6. Use brightener: Add an appropriate amount of brightener to the material to improve the brightness of the injection parts.

In view of the low brightness of ABS injection parts, we need to analyze and solve the problem from many aspects such as temperature, injection speed, material drying, mold maintenance and so on. In actual production, the corresponding solution can be selected according to the specific situation, so as to improve the brightness of the injection parts and ensure product quality.
