Cold forming technology
Cold forming is the case without heating the material punching, bending and stretching, the processing method. Cold molding process are cold forged, cold rolling, forging and so on. Roll forming machine
The main advantage of cold formed steel structure: 1, compared with thicker hot-rolled steel, cold steel can be processed into smaller loads and for a shorter span. 2, through the cold forming process can be economically unusual cross-section shape, obtain satisfactory strength to weight ratio. 3, consider the compact packaging and transport, can produce cross sections can be nested. 4, the environment under the action of gravity changes without stretching invisible.
Plastic material processing method, suitable for cold plastic plastic plastic or inorganic material, characterized by high-pressure and cold forming die in a sufficient period, then removed from the mold in the heating or not heating the furnace to continue to dry and Forming machine harden not made insoluble melting of the product. This method is rapid, low cost, good electrical insulation properties, water resistance, heat resistance, high insulation commonly used in the manufacture of electrical products. Sometimes refers to the glass transition temperature for plastic molding, see the solid phase forming.
