In the traditional rubber manufacturing plant, the master often adjusts rubber ingredients to meet the mold thickness, or the requirements of the soft hardness of the forming products, depending on the experienced experience. Though adjusted several times, it can also achieve the goal, but in the process, it is not known whether the best formula has been adjusted in addition to wasting valuable time and materials. Now, with the help of computer hardware and software, the curing test curve that can let a novice, easily adjusted to the reasonable ingredients and most balanced scorch and curing formula, which saves material and time, can ensure the quality, time. This is the biggest contribution to the rubber industry. The optimum opening time of sulfur added rubber is often combined with the quality control during the process of mass production. With the help of the computer software and the precise mechanical structure, this machine can find the best time of the mold opening for various kinds of sulfur adding rubber.
