Manufacturers long-term supply of iron crossed platform extrusion technology

Squeeze casting and pressure casting of different platforms dotted line is: The preform into a preheated mold preheated, under gravity poured into the liquid metal or alloy, and then the liquid into the action under the indenter prefabricated blocks, solidification of liquid metal under pressure. It was prepared by this process take a1203 zinc-based short fiber composites. Some people in Japan directly to the carbon and glass particles into a mold, and then ram acting on the tin liquid metal body squeeze into the mold in the compression stage, using 10t hydraulic press, the pressure is about 91MPa. Aihua will hold casting and squeeze casting melt together, the weight ratio of 3% to 6% of the package nickel-copper aluminum alloy powder is added to the stone liquid-solid alloy slurry, and then quickly squeezed into bearing blank agitator coated with a heat-alumina cement, speed of 400 ~ 1500r / min .. extrusion equipment for YA32-100 type extruder, pressure speed 7mm / s. Many people composites squeeze casting theoretically do in-depth discussion. Special study the solidification of the alloy casting manufacturing carbon fiber reinforced composites a356 kit and other savings in the use of the double squeeze was found in the pouring temperature high solidification occurs after the entire impregnation process due to the chilling effect of the mold and fibers, primary aluminum solid solution phase nucleation in the fiber gap start and gradually grew to the fiber surface; while the eutectic silicon phase is dependent on the carbon fiber surface Nucleation and Growth. and found that with the reduced solidification cooling rate, the eutectic silicon phase morphology by worm-like needle, massive shift to. Also someone studying CF / AL-4.5Cu Composite by Squeeze casting found that primary aluminum solid solution is in the fiber gap to the surface of the fiber grown nucleation; eutectic phase θ is dependent on the carbon fiber surface nucleation and growth due to the combination of the interface of this material is very strong, which is characterized by brittle fracture fracture. cooling rate (0.1 ~ 100 ℃ s-1) Squeeze Casting G-SIC Reinforced Aluminum Matrix Composites solidified organization, found that the cooling rate, the more uniform distribution of G-SIC particles. This is a high-end cast iron crossed platform molding technology, although difficult to implement relatively large, but we should vigorously promote these technologies, so in order to promote industrial optimization and faster, improve the technological content of the entire industry More information can be found on our website:. www. czmnjx.com
