What is the press compound?
The compound
sheet composition (SMC) is ready to use polymer polymer resin reinforced with glass in the form of a sheet that is commonly found in compression pressing processes. The product is produced by extruding the resin compound layer on plastic foil and applying sliced glass fibers to the surface. As soon as the fiber penetrates the resin, the upper layer of the plastic is applied and the finished resin leaf turns and leaves the ripening. When the resin matures, the sheet can be cut to size and placed in a mold where the temperature and pressure complete the curing process. The SMC process is desirable because it can be used to form complex shapes with small waste, requires minimal work and allows high production volumes. SMC is often the preferred choice for the formation of compressions and consists of flat leaves mature, glass fiber impregnated resins. The leaves are available in roles weighing up to £ 880. (400 kg) that are cut to size before forming. These resinThe roles are usually interlaced with plastic leaves to prevent layers to adhere to each other.
Typical production of the leaf compound includes the issue of a layer of compounds consisting of resin, catalyst, fillers, coloring, mold release and ripening on plastic. Glass fiber is then chopped to the strands of approximately 1 inch (25.4 mm) long and distributed to the surface of the resin layer. These strands evenly penetrate the layer to form a reinforcement matrix in which the second plastic leaf is placed at the top. The completed composite sheet is then converted and removed to the storage space, where it is left to ripen for approximately 48 hours. Once you appear, you want to warm up and pressure in the form, completely cure the leaf compounds and the finished product can be removed.
products made of pressing compound supplies show excellent mechanical strength, good surface appearance and excellent ELElectric insulating properties. Thanks to these characteristics, SMC products are ideal for boat production, electric components with high demand, parts of the body of the class A and sanitary goods. Processes using sheet metal formation are also attractive because minimal work is required, high production volumes and complex shapes are possible and very small scrap is generated.
