One: simplify the production process of rubber molding products, it can realize the high temperature and rapid vulcanization of rubber products, shorten the production cycle, improve the production efficiency. Second: the accuracy of mechanical production is many times higher than manual, increasing the qualified rate of products, saving raw materials and energy. Third: high degree of automation, reduce the labor intensity of human. But while bringing convenience, we should also recognize its shortcomings, such as very large investment in purchasing equipment and high maintenance cost. We believe that with the arrival of the era of automation, rubber injection machine will slowly progress and upgrade, and become more suitable for the needs of this society.
