[0002] High-temperature plastic impact resistance testing equipment is an instrument specifically designed to evaluate the resistance of high-temperature plastic materials to external impact forces. Its primary function is to simulate the impact conditions encountered in actual applications and measure the material's impact resistance under specific conditions, thereby providing a scientific basis for material application and selection. High-temperature plastics are widely used in aerospace, electronics, and automotive industries because they maintain excellent mechanical properties and chemical stability even under high-temperature conditions. The effectiveness of high-temperature plastic impact resistance testing equipment not only helps researchers understand the strength characteristics of materials but also promotes the development and application of high-performance plastics. Through systematic testing, companies can optimize product designs and improve product durability under extreme conditions, thereby gaining an advantage in a highly competitive market.

However, some existing test equipment has a relatively simple protective device during use, so when the plastic breaks and splashes, it is easy to cause damage to the workers, and the plastic fragments flying everywhere are not conducive to workers to collect. Therefore, it is necessary to solve this problem. Utility Model Content
