     The basic process of rubber products, but the production process is basically the same. The basic process of rubber products with general solid rubber as raw materials includes: plastic refining, mixing, calendering, pressing, forming and vulcanization of 6 basic processes. Of course, raw material preparation, finished finishing, inspection packaging and other basic processes are also indispensable. The process of rubber processing is mainly to solve the contradiction between plastic and elastic properties. Through a variety of technological means, so that elastic rubber into a plastic plastic rubber, and then add a variety of additives made of semi-finished products, and then through the vulcanization of plastic semi-finished products have become high elasticity, physical and mechanical properties of good rubber products.Plastic Parts Manufacturing
    Raw Materials Preparation: 1. The main raw material of rubber products is the basic material, and raw materials are grown in the tropics, the subtropical rubber tree on the tree by artificially cut the bark collected. 2. A variety of coordination agents are intended to improve the performance of rubber products and add auxiliary materials. 3. Fiber materials (cotton, hemp, wool and a variety of man-made fibres, synthetic fibres and metal materials, steel wire) is used as a rubber product skeleton material to enhance mechanical strength, limited product variants. In the raw material preparation process, the ingredients must be accurately weighed according to the formula. In order to make the raw rubber and the coordination agent can mix evenly, the material needs to be processed. The raw rubber should be baked in the 60--70℃ drying room and then cut gum, broken into small pieces, with a block of agent. such as paraffin, stearic acid, rosin, etc. to be crushed. If the powder contains mechanical impurities or coarse particles need to be filtered to remove liquid such as pine tar, Coumarone needs heating, melting, evaporation of water, filter impurities, the coordination agent to be dry or easy to caking, mixing if not dispersed uniform vulcanization when the bubble will affect product quality.Plastic Parts Manufacturing
     The rubber is flexible and lacks the necessary plasticity in processing, so it is not easy to process. In order to improve its plasticity, it is necessary to carry on the plastic refining of the rubber, so that in the mixing agent will easily disperse evenly in the raw rubber, at the same time in the calendering, molding process will also help improve the permeability of the plastic material infiltration into the fiber fabric and molding mobility. The process of degrading the long chain molecule of the rubber to form plasticity is called plasticizing.Plastic Parts Manufacturing
     There are two kinds of plastic refining methods, such as mechanical plastic refining and thermoplastic smelting. Mechanical plastic refining is at a low temperature through the mechanical extrusion and friction of the role of plastic smelting machine to shorten the molecular degradation of long chain rubber from high elastic state to plastic state. Hot-plastic smelting is to the raw rubber into the hot compressed air under the action of heat and oxygen to shorten the long chain molecule degradation to obtain plasticity.Plastic Parts Manufacturing
