Sand casting is the most common method for simple, large-diameter pulleys at high volume \u2014 cost-effective when tolerances are loose, and profile complexity is low. For pulleys where bore accuracy, groove profile, and spoke geometry matter, investment casting reduces machining work and produces more consistent components across batches.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t
