Shrinkage and shrinkage are common casting defects in foundry production. Shrinkage is a pore that shrinks during the condensation process and cannot be replenished with a metal solution. It has an irregular shape and a rough wall, and is generally located at the hot joint of the casting. Shrinkage and stomata are often very similar in appearance and are often easily confused. Generally speaking, the inner wall of the pores is smooth, while the inner wall of the shrinkage pores is the tip of a branched crystal. (A) Open shrinkage (b) Angle shrinkage (c) Core shrinkage (d) Internal shrinkage Shrinkage is the formation of scattered and fine pores in the last solidified area of the casting without the shrinkage of the metal solution. It often appears at the thicker sections of the casting and at the junctions or thick nodes of the thick and thin sections. The shrinkage distribution area is much larger than the shrinkage holes, and it is often hidden inside the casting, sometimes not

The contradiction between the rising living standards and the relatively backward material conditions has become much compromised due to the emergence of some things. For example, the emergence of the steam engine in the first industrial revolution completely changed the handicraft industry at that time, making great progress in social development, and the emergence of the second power added wings to the development of society. Aluminum Fence Casting Of course, the great success brought by each change is inseparable from the obscure workers. Seeing some trivial things in daily life can lead to some thought-provoking principles. For example, the basic building materials of common fences in our lives, from the former iron material to the current zinc steel fence, plastic steel, aluminum alloy and other materials. These materials can be divided into homes and units according to different uses. Generally, iron or aluminum alloy materials are used for highways and streets. Plastic

The use of fireplaces abroad has a long history, so when designing a cast iron fireplace , it is not a simple masonry stacking, just like our rural stove, a cooker built by a good craftsman , Will not run out of smoke from the furnace door! Today,  the cusom cast iron fireplace supplier  simply said the advantages of  cast iron fireplace .  Cast Iron Fireplace Modern real fire fireplaces, as the name suggests, are an extension of the development of modern science and technology. Modern scientific researchers have used modern technology and high-tech materials to improve traditional fireplaces in various aspects. High-tech modern real fire fireplace for energy. Early steel plate structure, but easy to use deformation, are now mostly cast iron fireplace core. Use advantage Easier installation: It is no longer limited to single buildings such as villas and TOWNHOUSE. It can also be used in general residences, apartments, hotels, and office buildings, and is not limited by th

Aluminum castings play a very important role in the current industry, and they 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 casting technology is also increasing. When we use and use the aluminum casting process, do we know what are the advantages of aluminum castings produced by aluminum casting, our aluminum alloy foundry will take you to understand some of the advantages of aluminum castings. Furniture Cast Aluminum Part The main advantages of aluminum castings: Aluminum castings, not only from the use of materials, but also from other aspects, have some advantages not found in other castings, which are mainly: (1)  Furniture cast aluminum part  is beautiful in appearance and light in weight, so it can be easily transported. And in cars, that's a big plus. (2) The density of aluminum alloy is obviously smaller than that of cast iron, cast steel, et
