With the rapid development of the technology of injection molding machine, demands for high level factory automation are increasing. The modern injection molding machines are often equipped with mechanical hands to improve efficiency. Injection mechanical hands are specially equipped for full automatic injection. It not only can reduce the heavy labor work, but also improve labor condition and safety production. It plays in important role in improving the efficiency of machine, stabling the quality of products, reducing scrap rates, lowering production costs and strengthening the competitiveness. We are one of the companies who firstly equip them and continue searching expanding the application projects of mechanical hands in manufacturing buckets.
