Wear-resistant plastic is an important engineering material and is widely used in the manufacturing industry. It shows obvious differences in properties under different hardening methods, which makes material selection a key link for enterprises to improve product quality and production efficiency. First, the thermal hardening process treats the material at high temperatures to give it superior mechanical strength and wear resistance. According to data, under thermal hardening conditions, the mechanical strength of wear-resistant plastics can be increased to 150% of the original. This is particularly important in industrial applications that require high strength and high wear resistance. However, the gas hardening process is carried out at room temperature, making the operation easier. According to statistics, the application process time of wear-resistant plastics treated by gas hardening is about 30% shorter than that of thermal hardening. In addition, gas hardening materials also have good environmental adaptability and can be used in more diverse environments. By comparing the advantages of thermal hardening and gas hardening, we can see that thermal hardening is suitable for application scenarios that require high strength and high wear resistance, while gas hardening is more suitable for scenarios that require flexible operation and wide environmental adaptability. When choosing a hardening method, companies should make rational decisions based on their own production needs and application environment. In general, heat curing and gas curing of wear-resistant plastics each have their own unique advantages. It is hoped that the comparative analysis in this article will help companies make more informed decisions on material selection, thereby improving product quality and production efficiency.
