1. Dropping plastic is the use of thermoplastic polymer materials with state variable characteristics, that is, under certain conditions with viscosity, and at room temperature and can restore the characteristics of solid state, and the use of appropriate methods and special tools inkjet, in its viscous state according to the requirements of the shape of the design, and then at room temperature curing molding.
2. Compression molding method is mainly used in the production of thermosetting plastic products. Molding after heating to melt, pressing die, and then after heating crosslinking curing, demoulding after the product.
3. Resin transfer molding is a process of infusing resin into a closed mold to infiltrate the reinforced material and solidify it. This technology can not prepreg, autoclave, effectively reduce the cost of equipment, molding cost. This technology has developed rapidly in recent years, and has been widely used in aircraft industry, automobile industry, ship industry and other fields, and has developed many branches such as RFI, VARTM, Scrimp, Sprint, etc., to meet the application needs of different fields.
4. Extrusion is the use of punch or punch placed in the die in the blank pressure, so that plastic flow, so as to obtain corresponding to the mold hole or punch shape of the parts of a pressure processing method. During extrusion, the billet produces a triaxial compressive stress, and even the billet with low plasticity can be extruded into shape.
5. Thermal molding is a special plastic processing method to process thermoplastic sheet into various products. A special plastic processing method for processing thermoplastic sheets into various products. The sheet is clamped on the frame and heated to the softening state. Under the action of external force, it is glued to the mold surface to obtain the shape similar to the mold surface. After cooling finalize the design, it becomes products by dressing.
