Causes and solutions of degradation of plastics produced by injection parts

Degradation of plastics produced by injection parts is a critical issue that needs to be addressed to increase the lifespan and effectiveness of plastic products. This problem is caused by several factors, including environmental conditions, the quality of plastic materials used, and the injection molding process. In this article, we will discuss the causes of plastic degradation and provide solutions to help mitigate the effects.

Environmental conditions are a significant factor that contributes to the degradation of plastics. Exposure to heat, UV rays, and moisture are known to accelerate the degradation process. When plastics are exposed to high temperatures, they undergo a chemical reaction that causes them to change their structure, making them brittle and less durable. UV rays can also trigger a process called photo-degradation, which breaks down the molecular structure of plastics, making them weaker and more prone to damage. Moisture in the environment can cause the plastic to swell, leading to cracking and other issues.

The quality of plastic materials used in injection molding also plays a vital role in determining the lifespan of the product. When low-quality plastic materials are used, they are more likely to degrade faster than their high-quality counterparts. This degradation could occur due to the presence of impurities that affect the structural integrity of the plastic.

The injection molding process can also be a cause of plastic degradation. Molding temperatures, pressure, and cycle times can all impact the quality of the finished product. Improper injection molding processes can cause the plastic to become brittle, making it more susceptible to damage and degradation.

To mitigate the causes of plastic degradation, various solutions can be implemented. One solution is to use high-quality plastic materials that have been tested and proven to be resistant to degradation. Additionally, the injection molding process can be optimized to ensure that the plastic is molded correctly, reducing the risk of plastic degradation.

Another solution is to use additives that can improve the plastic's resistance to environmental factors such as UV radiation and moisture. These additives can be used in combination with high-quality plastics to create more durable and long-lasting injection-molded products.

In conclusion, the causes of degradation in plastics produced by injection parts are complex and multifactorial. To address this problem, it is important to consider environmental conditions, the quality of plastic materials used, and the injection molding process. By using high-quality plastics, optimizing the injection molding process, and using additives that improve the plastic's strength and resistance, we can mitigate the effects of plastic degradation and create long-lasting, durable products.
