How can low pressure casting prevent the generation of waste products

Low pressure casting means that the mold is usually placed above the sealed crucible, and compressed air is introduced into the crucible to generate a low pressure (0.06~0.15MPa) on the surface of the molten metal, so that the molten metal rises from the furnace. The riser tube fills the mold and controls the solidification casting method. This casting method has good feeding and compact structure, easy to cast large thin-walled composite castings, no risers, and metal recovery rate of 95%. No pollution, easy to realize automation. However, the equipment cost is high and the production efficiency is low. Therefore, low pressure casting is usually used for casting non-ferrous alloys.

Development Prospect of Low Pressure Casting Industry

China is a big country of low pressure casting. To become a strong casting nation, it must overcome resource, energy, talent and environmental issues. High quality, environmental protection is the development direction of low pressure casting industry. Therefore, it is necessary to use high technology to improve the quality of castings and change the phenomenon of low technology content of Chinese castings in the international market. China has entered a new era, and the low-pressure casting industry is facing good development opportunities. The rapid development of China's economy has entered a stage of globalization and high-quality development. It provides a good opportunity for the transformation of the low-pressure casting industry, and the casting industry will also enter a high-quality development stage.

What are the surface processing technology of low pressure casting

Low pressure casting is usually used in the processing of many aluminum parts, and it is also very common in our lives. However, if the surface treatment is not good during the processing, it will also have a greater impact on the quality of the product. Therefore, when we choose this kind of low-pressure casting castings, there are many aspects that must be paid attention. What should we pay attention to? Let's find out below.

Causes of Pre-foaming Effect on Carburization of Castings in Low Pressure Casting

The pre-foamed parts of low-pressure castings are usually more precise in size and less likely to deform. Compared with sand casting, its internal quality has fewer pores, smooth surface, and can achieve various mechanical properties. The vanishing foam has matured in ordinary cast iron technology.

Aluminum casting factory: what is aluminum casting modern molding technology

Complex aluminum casting casting is a new technology with electromagnetic pump low pressure casting technology as the core, aluminum smelting and molding plastic purification technology, manufacturing core new technology as the core, to produce high quality aluminum castings. The electromagnetic pump low-pressure casting metal melt transmission system has stable flow and convenient flow control, which reduces the backward suction of molten alumina during the process and is easy to realize.

Die casting manufacturers: what is the die casting process

The traditional die casting process mainly includes four steps, or called high pressure die casting. These four steps include mold preparation, filling, injection and sand drop, which is also the basis of various improved die casting processes. In the process of preparing the die casting, the lubricant needs to be injected into the mold cavity. In addition to helping control the temperature of the mold, lubricants can also help demolding castings. Then, the mold can be closed, and then the molten metal is injected into the mold under high pressure.

Die casting manufacturers: what is die casting

Die casting is a metal casting process commonly used by die casting manufacturers, which is characterized by the use of the cavity of the mold to apply high pressure to the molten metal. The mold is usually made of a high-strength alloy. This process is somewhat similar to injection molding. Most die castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin and lead-tin alloys and their alloys. Depending on the type of die casting, die casting manufacturers need to use a cold chamber die casting machine or a hot chamber die casting machine.

Aluminum Foundry Factory: Pouring Temperature and Advantages of Aluminum Casting

The aluminum foundry improves the overall design of the castings throughout the actual operation of casting aluminum castings. When constructing, avoid inclination angles and wall thicknesses to ensure that they are symmetrical and smooth. Aluminum castings take measures to expand the tolerance of the sand mold (core) to ensure that a part of each of its castings is also condensed or sorted to improve the design of the gating control system.

Aluminum casting manufacturers: the main advantages of aluminum casting

Aluminum casting manufacturers in the actual operation of casting aluminum alloy castings in the whole process will have other casting unparalleled advantages, especially in the automotive new energy so far, its casting aluminum alloy profiles in the car industry production has been widely used. Subsequently, the aluminum alloy profile sand casting process has excellent casting effect. Due to the low melting point, aluminum foundry manufacturers can generally adopt casting methods such as metal material type and working pressure casting to develop the inner letter quality of castings, limit precision and smooth surface level and its production output power.
