Irregularly shaped parts are manufactured using UHMWPE (ultra-high molecular weight polyethylene) and HDPE (high-density polyethylene). The combined properties of these two materials provide multiple advantages: UHMWPE offers superior wear resistance, corrosion resistance, impact resistance, and self-lubricating properties, while HDPE provides good corrosion resistance, high toughness, and cost-effectiveness. The combination of these two materials adapts to various working conditions. These irregularly shaped parts can be customized into various non-standard shapes according to the application scenario and are widely used in chemical, port, mining, and food processing industries, fulfilling functions such as wear resistance, corrosion resistance, and cushioning.
