90MM-Stainless steel oil cup with tungsten steel handle ring

The stainless steel oil cup and tungsten steel knife ring are the high-precision core components of the inkjet printer. They are made of 304 stainless steel oil cup and super-hard tungsten steel knife ring, featuring both corrosion resistance and excellent wear resistance. The closed structure effectively prevents solvent evaporation and maintains the stability of the ink; the tungsten steel knife ring is precisely ground, with a sharp and straight knife edge, ensuring thorough ink scraping and clear, residue-free printed images. This combination is resistant to acids and alkalis, and can withstand wear better than ordinary steel parts, making it particularly suitable for long-term high-load production. It is widely used in precision inkjet printing in industries such as electronics, hardware, and plastic products, significantly improving printing quality and efficiency.
