The density of the lost foam pre-expanded beads determines the density and degree of fusion of the various parts of the die, and the quality of the die determines the quality of the casting. The main factors affecting the density of the pre-expanded beads of the lost foam are the quality of the raw materials […]
One of the characteristics of the mold-molding mold is that hot steam and cooling water need to be introduced into the closed mold gas chamber to mature and cool the foam particles, which is different from the molding environment of molds such as plastic molds, metal molds and die-casting molds. The mold needs to form […]
With the rapid development of the automobile industry, the production and use of large-scale stamping parts has increased sharply, and the demand for medium and large-sized molds has also increased significantly. In recent years, a large number of researches and practices have shown that the yield strength of nodular cast iron is higher than that […]
According to the sharding scheme, the gearbox needs to be divided into 2 sets of fully automatic lost foam molds and 1 set of adhesive molds. According to the foundry manufacturer’s automatic vertical forming machine and vertical automatic glue machine, the lost mold structure and adhesive The modular structure uses the following scheme: First, the […]
The production of aluminum alloy castings by the lost foam process has become an unstoppable trend. Cylinder top cover, new energy vehicle gearbox, heavy truck gearbox, etc., have gradually realized mass production in China, especially the mass production of 12-speed truck gearboxes. It marks the arrival of a new era of China’s lost foam aluminum […]

From the choice of materials to the production of white molds, the process is ultimately. First of all, about the white mold In the […]
The surface strengthening and modification technology of the forging die can design the surface of the die and the substrate as a system, and comprehensively utilize the surface strengthening modification technology and the coating technology to make the surface itself difficult to obtain and hopefully have specific performance. . The treatment technology that uses modern […]
First, the basic production requirements of lost foam casting technology As a method of near-static forming of castings, lost foam casting technology has developed rapidly in recent years. In foreign countries, the lost foam casting technology has shown great vitality due to the mechanized and automated lost foam casting production lines being put into operation […]
What is Lost foam sand casting? The sand casting process is a casting method in which sand is used as a main material to prepare a mold. Sand casting is the most traditional casting method. Because sand casting is characterized by its own shape (not limited by the shape, size, complexity and alloy type, short […]
