Introduction to segmental moulding of rubber

Segmental moulding method firstly moulds the raw rubber for a certain period of time (about 15min), then cools down the piece and parks it for 4~8h, and then moulds it for the second time, so that moulding is repeated for several times until it reaches the requirement of plasticity. When the plasticity requirements of the plasticity of the rubber is high, with a plastic or thin pass plasticising can not achieve the purpose, and an effective method. High production efficiency, high plasticity and uniformity of the plasticity of the plasticity of the rubber, the production is more widely used; production management is more troublesome, covers a large area, is not suitable for continuous production. According to different plasticity requirements, generally can be divided into two plasticising or three plasticising. For natural rubber a section of the plasticising rubber Vickers plasticity up to 0.3 or so, two sections of the plasticising rubber up to 0.45 or so, three sections of the plasticising rubber up to 0.55 or so.
