In industrial manufacturing or life, you will see many brass parts, most of which are made by investment casting. For example, many accessories such as brass jewelry, brass pendants, brass ornaments and so on that are common in our lives are produced by investment casting. The casting performance of brass in copper alloys is relatively good, but its shrinkage is relatively large, and it is prone to shrinkage holes, cold cracks, deformation and other problems. It is necessary to reduce the pouring temperature as much as possible in the actual pouring to improve this problem. Of course, there are many other processes to improve this shortcoming, such as selecting a good sand mold, setting a riser, or setting a gating system, etc., which can be improved, and the details are discussed and analyzed according to the structure of the workpiece.
Brass casting is not only used in jewelry, pendants, ornaments and other handicrafts in daily life, but also widely used in industry, because copper itself has good corrosion resistance and superior conductivity. There are also many brass castings produced by SCZY. The common ones are some handicrafts, some architectural accessories, and auto accessories. We also support secondary precision CNC machining and surface treatment. Let customers have no worries.

The new joint venture company's Wuchuan investment accounted for 72%, and the WISCO Group Egang Company invested 28%, with an initial investment of 2.5 billion yuan. It integrates the development, design, manufacture, transformation and repair of various types of ships, marine engineering and ancillary equipment. After the production, the production capacity of 24 marine engineering auxiliary vessels and other special engineering vessels will be formed.
In order to ensure the supply of steel plates, Wuchuan also cooperated with three enterprises including WISCO Group Egang Co., Ltd. to form Hubei Egang Zhongchuan Steel Processing and Distribution Co., Ltd., which specializes in building a steel pretreatment line and several blanking equipment in Shuangliu to provide nearby services. .
In 2009, Wuchuan and Xinzhou District signed the “Shuangliu Special Ship and Heavy Equipment Manufacturing Base Project (Phase I) Investment Agreementâ€, and acquired 5,000 mu of land in the Gulong Industrial Park of Xinzhou District to build the largest special shipbuilding industrial cluster in Central China. The formation of a shipbuilding base for product development and construction integration, and a bridge steel structure manufacturing base is equivalent to rebuilding a military ship.
Wu Ship said that the new company that was signed this time will be the main carrier of the special ship area in the Shuangliu base of the Wuchuan Ship, and it is the main force for the martial arts ship to rebuild the "new martial ship".
At present, the steel structure of the 160,000 square meters joint processing plant of Shuangliu Base has been fully completed, and it is expected that the conditions for commencement will be reached in October today. The ship supporting industrial park is under planning, mainly focusing on large-scale shafting, rudder system, marine special valve parts, new special materials, marine craft system for supporting processing and technology research and development, forming an international standard and domestic first-class professional high-end special ship supporting industry.

[China Ship Network (CnshipNet China)] On August 10, two heavyweight upstream and downstream enterprises in Han joined forces to invest 2.5 billion yuan to extend the industrial chain. Two "Wuzitou" Wuchuan and WISCO jointly established Wuhan Shuangliuwu Ship Heavy Industry Co., Ltd. to build a special ship base in Shuangliu. The two teams have joined forces to achieve seamless links between upstream and downstream: WISCO has been selected as one of the world's top 500 companies, and ranks among the top four steel companies in the world. It has industry “speaking rights†on many high value-added and high-tech steel plates, among which there are steel for ships. Wushu is a leading shipbuilding enterprise in China. Last year, the output value has reached 8.5 billion yuan, and it will exceed 26 billion yuan by 2015.
