Technical Innovation:
This product utilizes gradient sintering technology to create a grain gradient distribution structure within the material, ensuring both high surface hardness and improved overall impact resistance. The top rectangular protrusions employ a bionic support structure design, enhancing load-bearing capacity while reducing weight. The symmetrical holes use special chamfering processes to effectively prevent stress concentration, increasing the product's service life by more than 3 times compared to traditional structures under extreme working conditions.
