When no big-size plate vulcanizing press machine, through design deformation mold, could mold big-size high precision O-shape rubber seal on little plate vulcanizing press machine. 在不具备大平板硫化机及大型加工设备条件下,通过设计加工“变形模具”,在小平板硫化机上生产出大规格、高精度的O型橡胶密封圈。
The pin gear-type precision seeder is composed of a wheel body, a rubber ring, a needle wheel and an isolation plate. 本实用新型主要由轮体、胶圈、针轮、隔种板等构成。
