Main advantages of aluminum alloy die castings
02-01
Aluminum alloy die castings play an important role in today's industry and are widely used in many industries. With the continuous development of society, people's living needs are getting higher and higher, and the demand for aluminum die casting process is also increasing.
Main advantages of aluminum alloy die castings:
1. Aluminum alloy die castings are beautiful in appearance and light in quality, and can be easily transported during operation.
2. The density of aluminum alloy is significantly lower than that of cast iron and cast steel, but its strength and corrosion resistance are much higher. Therefore, under the same load weight, the use of aluminum alloy die castings can reduce the weight of the structure.
3. For the surface of aluminum alloy, it has good surface gloss and casting performance.
The mechanical properties and tensile strength of aluminum alloy die castings have great resistance to the fracture of their materials during manufacturing. To some extent, their elongation is an index to measure the brittleness and plasticity of materials. Hardness is the resistance of material surface to plastic deformation caused by pressing or friction of hard objects.
The working temperature and humidity of aluminum alloy die castings, the medium and air tightness requirements of the workpiece contact, and the entire product can meet the corresponding requirements.
The surface accuracy and surface roughness of aluminum alloy die castings will directly affect the working rate of their pumps and hydraulic systems and the development of cavitation to a certain extent. The strength and chilling resistance of aluminum castings such as cylinder block, cylinder head, cylinder liner, piston ring and exhaust pipe of internal combustion engine will directly affect the service life of the engine.
Sand casting is adopted for aluminum alloy die castings. The main reason is that compared with other casting methods, sand casting has the advantages of low cost, simple production and processing technology, and short production development cycle. When the wet sand can not meet the requirements, consider using clay sand surface dry sand mold, dry sand mold or other sand mold.

Classification and application of cemented carbide punches
As we all know, cemented carbide has a wide range of applications in the industrial field, and the cemented carbide punch we are going to talk about today is one of them. The cemented carbide punch, also known as the cemented carbide punch, is a precision die part with high precision, high hardness and good bending strength made of cemented carbide round bar. Usually, we use carbide punch, die button and bushing together for stamping iron tower.

Digital upgrading of domestic casting industry and rapid growth of additive manufacturing industry
The domestic traditional casting production process belongs to the non-digital simulation process mode, and the production process and casting result prediction highly depend on the personal experience and ability of technicians. Other industrial products manufacturing industries (automobile, aerospace, shipbuilding, machining, etc.) have gradually completed the full digital upgrade of design and manufacturing.

Cause Analysis of Defects in Die Casting
1) The design of the die casting itself is unreasonable: the wall thickness, shape, round corner, demoulding angle and porosity are not appropriate. 2) Performance problems of die-casting machine: insufficient injection force and locking force, improper casting pressure and filling speed, mismatching of casting size and projected area of die-casting machine capacity, etc.

Causes and solutions of blowholes in die casting opening
Zinc die-casting is the process of filling molten zinc into the mold cavity rapidly and under high pressure. The time for liquid zinc to fill the cavity of the die-casting mold is very short, which is usually several hundredths of a second or several thousandths of a second. The pores formed in the process of die casting have smooth surface, and the shape is mostly circular or elliptical. They mostly exist on the surface or subcutaneous pores of the casting, and may also exist in the casting. The main source of pores is the gas involved in the process of die casting or the gas evolution of zinc liquid. 1、 Air entrainment during die casting.

Causes and Solutions of Die Casting Deformation
Reasons for deformation: the overall or local geometry and design of the die casting do not match the finished product, which is called deformation. 1. The structural design of die castings is not perfect, which is caused by uneven shrinkage; 2. The temperature of die casting mould is high, the hardness of its own mould is not enough, and the cooling time is not enough; 3. The mold setting position is unreasonable and deflected;
