We take pride in employing an advanced production arsenal equipped with cutting-edge methodologies of silica sol precision casting, resin sand casting, and heat treatment. In addition, our operational procedures are bolstered with ten advanced Fanuc six-axis robots to ensure optimal performance in high-intensity labor processes.
