FAQ
QPrecision casting is also called investment casting
Sand casting production of casting precision, surface finish, material density and metallographic structure, mechanical properties and other aspects are often poor, so when the casting of these performance requirements are higher, should use other casting methods, such as investment (lost wax) casting, die casting, low pressure casting, etc., the following by the company editor for everyone to introduce:
Features and advantages of precision casting:
Precision casting, also known as investment casting, with other casting methods and parts forming methods compared to investment casting has the following characteristics:
1. The casting size precision is high, the surface roughness value is fine, the size precision of the casting can reach 4-6 grade, the surface roughness can reach 0.4-3.2 μm, can greatly reduce the machining allowance of the casting, and can realize the manufacturing without allowance, reduce the production cost.
2. Castings with complex shapes and difficult to process with other methods can be cast. The contour size of the casting is as small as a few millimeters to thousands of millimeters, the thinnest wall thickness is 0.5mm, and the smallest hole is below 1.0mm.
3. Alloy materials are not limited: such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy and high temperature alloy, titanium alloy and precious metal and other materials can be used in precision casting production. For alloy materials that are difficult to forge, weld and cut, it is especially suitable for precision casting production.
4. High production flexibility and strong adaptability. Can be used for mass production, but also for small batch or even single-piece production.
In summary, precision casting has the advantages of small investment scale, large production capacity, low production cost, simple process of complex products and quick investment. Thus, it is in a favorable position and has a bright future in the competition with other processes and production methods.
QWhat materials will be used in precision casting?
In precision casting, what materials are generally used?
In precision casting, we can use stainless steel, carbon steel, alloy steel, etc., which can be used for precision casting. However, it is still up to the specific situation to choose.
Precision casting, which can be referred to as precision casting, is a special casting method. Generally speaking, the parts obtained by precision casting do not need to be machined anymore, because it can obtain a more accurate shape and a higher casting accuracy. However, we can also heat treat and cold work the product according to its needs. The types of precision casting mainly include investment casting, pressure casting and so on.
QDevelopment Trend and Prospect Analysis of Foundry Industry
QWhat testing equipment is required for the foundry industry laboratory?
The foundry industry laboratory needs the analysis of molten iron carbon and silicon in front of the furnace or the analyzer of molten iron carbon and silicon manganese in front of the furnace, and the analyzer of the five major elements (chemical analysis). The analyzer of the five major elements is commonly known. In fact, the analyzer of the five elements can analyze many elements (C, S, Si, Mn, P, Ni, Cr, Mo, Ti, Cu, W, V, Σ RE, Mg, etc.); 4. Universal testing machine; 5. Hardness tester; 6. Ultrasonic flaw detector; 7. Box-type electric furnace (alias: muffle furnace) 8. Drying oven, etc.
QApplication of casting materials
Since the advent of the casting material, Baozhu sand has been widely concerned by the casting industry, and is widely used in resin sand (furan resin, phenolic resin), water glass sand (organic grease, CO2 hardening), and coated sand. It is suitable for various casting methods such as V method and VRH. Lost foam can not only greatly improve the casting quality, but also easy sand cleaning and simple and convenient sand mixing process (single piece and small batch of local sand in large steel casting plants can be mixed manually with a small amount of sand). For most castings, coating can be omitted, especially suitable for making castings with high quality requirements. The fluidity and filling property are good, and good formability and mold strength can be obtained. Good collapsibility, easy sand cleaning operation. Binder usage than other similar sand has greater savings. Low thermal expansion rate produces high dimensional accuracy of castings, few cracks and surface defects, and high yield of castings. Less casting production process of dust pollution to the production environment, good regeneration, reduce industrial waste emissions, conducive to environmental protection. Good fire resistance. Its application in lost foam casting has significantly improved the casting defects caused by traditional sand. There is a certain period of adaptation from quartz sand to jewel sand. After trying, some domestic enterprises have made many achievements in the application of jewel sand.
The high manganese steel castings produced by Jilin Innovation Lost Foam Equipment Co., Ltd. have a very serious phenomenon of sand sticking and sand inclusion before using jewel sand. It takes a lot of manpower and material resources to clean and polish the surface of the castings, which not only increases the production cost of the castings, but also causes the surface quality of the castings to be unsightly. This type of casting defect has been completely eliminated after the use of jewel sand. Cost savings of 6%.
Yulin Diesel Engine Factory uses Baozhu sand to make diesel engine water kit, which maintains the characteristics of the original sand, overcomes the shortcomings of large expansion coefficient of the original sand, large amount of binder, large amount of gas, etc., reduces the amount of resin added, and improves the yield of the product.
Dozens of manufacturers such as Luoyang Luobei Steel Plant, Ruyang Xingrong Machinery Plant and Shandong Hengcheng Foundry added 20-30% of 140-320 mesh fine sand to the jewel sand of 30-40 mesh sand. The results showed that the sand was also non-sticky, had sufficient air permeability and was easy to clean. In order to reduce the production cost, some steel casting plants adopt the method of local single-sided sand, which also plays the effect of non-sticky sand.
