Congratulations on the website of Jinzhou Shuangling Precision Casting Co., Ltd.
Jinzhou Shuangling Precision Casting Co., Ltd. is located in Tienan, Shuangyang Town, Jinzhou City, Liaoning Province. The company is 13 kilometers away from Jinzhou Airport and 23 kilometers away from Jinzhou Port.
Established in March 1985, the factory is called “Jinzhou Shuangling Precision Foundry” and is affiliated to the collective enterprise of Shuangyang Town.
In May 2008, in order to develop and expand the scale of the company and better revitalize the economy of Shuangyang Town, the Shuangyang Town Government decided to restructure the former Jinzhou Shuangling Precision Casting Factory into Jinzhou Shuangling Precision Casting Co., Ltd. Changed from collective ownership to private limited companies.
The company now covers an area of 10,000 square meters, construction area of more than 3,000 square meters, more than 10 million yuan in fixed assets. More than 100 employees, including 55 professional and technical personnel.
Our company adopts water glass production technology. At present, we produce more than 3,000 kinds of products, the minimum production can be 0.015kg, and the largest casting can reach 70kg. It is used in mining machinery, engineering machinery, automobiles, etc., with an annual production capacity of 2,000 tons.
More than 30 sets of production equipment, including one German OBLF GS1000-II direct reading spark spectrum analyzer for guiding electric furnace production; one 500kg medium frequency induction electric furnace, two 250 kg medium frequency induction electric furnaces, and one 100kg medium frequency induction electric furnace; One machining center.
Before 2012, the company mainly produced rough parts. In 2012, it began to transform and process finished castings.
The company has passed ISO9001: 2000 quality management system certification. At present, more than 100 products have been exported to Japan, the United Kingdom, Singapore, Germany, the United States and other countries.
In recent years, with the continuous improvement of the industrial chain of China's precision casting parts industry and the continuous improvement of the technical level, the downstream demand field has shown an increasing demand for precision casting parts. However, the traditional precision casting production process still has many problems, which is plagued by a large number of precision casting manufacturers. In this market background, with its years of experience in the foundry industry, using its high-performance light-curing 3D printing equipment, it has launched a new Quick Casting application solution for integrated systems. It can effectively solve the pain point problem in the traditional precision casting process, and at the same time guarantee the production of high quality castings.
Ma Tian loose iron stainless steel: This kind of stainless steel body-centered cubic structure (BCC) can attract the magnet and get it from the Aostian temperature, which has the best corrosion resistance, but the material is hard and brittle, then it is returned. Fire can increase ductility, but corrosion resistance will decrease, especially tempering between 450 and 650 degrees Celsius, causing carbon atoms in the crystal lattice gap to diffuse and chromium to form a network of chromium carbide causing adjacent areas. The consumption of chrome element lowers the chromium content, prevents the formation of a protective film, and loses corrosion resistance, so special care is required. The following are the heat treatment temperatures for various granulated iron-based stainless steels.
Precision casting is a casting method compared to conventional casting processes. It achieves relatively accurate shape and high casting accuracy. It is more common to first make an electrode of the desired blank (with little or no margin left) and then use the electrode to etch the mold body to form a cavity. The wax is then cast by casting to obtain the original wax pattern. A layer of high temperature resistant liquid sand is applied to the wax pattern. After obtaining a sufficient thickness, it is air-dried and then heated to dissolve the inner wax mold to obtain a cavity conforming to the desired blank. The cast iron water is poured into the cavity, and after the curing, the outer casing is peeled off to obtain a precisely manufactured product.
