Precision Casting, How Much Do You Know?

As far as we know, die casting is a universal non-expendable technique. In the technique, metal are forced into the mold cavity under high pressure. And die casting molds can be used repeatedly to produce castings in a variety of sizes, shapes, and wall thickness. Besides, the molds cavities are precisely designed to produce complex shapes with accuracy, surface finish and attractiveness. Previously, die casting only uses low pressure injection method, but now high pressure techniques such as squeeze casting and semi-solid casting methods are applied in this field. What is more, only tin and lead were die cast in the past, but today magnesium, copper and other alloys are also cast by this process.

Precision casting,We generally do not engage in this industry is not going to know. For one relative precision casting casting method in terms of traditional casting process. It can get relatively accurate shape and high precision casting. The more common practice is: first make the desired electrode blank (can be left very small or no margin left margin), and then with a specific electrode corrosion mold to form a cavity. Then casting wax casting method, obtain the original wax model. On wax brush on a layer of high-temperature liquid abrasive. After obtaining a sufficient thickness to be dry, plus temperature, the internal mold wax melted away, and get the same blank cavity required. Then cast in a mold cavity in the molten iron, after curing, the shell off, you can get precision manufacturing finished it!

Generally speaking, the Precision Casting process is used in the iron industry to make iron products depending on clients’ requirements. And with the introduction of automobiles in the early 20th century, the iron consumption in automobile companies has increased rapidly all over the world.We drove a lot of people every day, but do not know the car, there are many precision casting parts. Recently, the automobile companies still remain as the largest consumer of metal castings. Besides, automotive castings are a bit different from other iron castings. Since the products of these castings forms important parts of a vehicle, the casting has to be perfect and flawless.

At present, casting as a precise process, is widely used in automobile sector to produce a great deal of automotive components. These components are manufactured by placing the molten iron in molds which are specifically designed according to the requirements of the automobile industry. Then the cast products are taken out from the molds and are filled in the automobiles. Recently, nearly all equipments in an automobile are made of cast metals.

As the casting process is quite intricate one, it needs to be completed perfectly in order make the products flawless. Clients in need of such products should always take the help of professional experts who can give effective suggestions regarding the products. Quality check is absolutely essential before buying such product because compromising with the quality may result in the lack of the desired result.

We all know casting is one of the oldest process that done on metals, and now, it is widely used in producing all kinds of Precision Casting . Generally speaking, there are four main types of castings, say, sand casting, permanent mold casting, plaster casting, and die casting. According to different usages and the properties of the product required, each type of casting has its own advantages and disadvantages.

Ever coin has two sides, so does die castings. It has both advantages and disadvantages. On one hand, it is a economical process that can be used for a wide range of complex application, and the parts made by technique have longer service life, dimensional accuracy and close tolerance.Besides, this process can be fully automated without any post machining. Meanwhile, the mold can be used repeatedly. However, on the other hand, the casting must be smaller than 600 mm, and the weight must be between 30 grams. Also, it is high initial cost and limited to high-fluidity metals.
