Recently, Xiangshan Chuangyi Metal Products Co., Ltd. has carried out research and development in liquid extrusion of aluminum alloys, gravity casting of aluminum alloys , and semi-solid extrusion casting of aluminum alloys at low pressure . The new semi-solid process developed by the company is: firstly melting the metal liquid in a high-precision temperature-controlled melting and holding furnace, pouring it into the intermediate container for heat preservation at a temperature slightly higher than the melting point of the alloy, and then controlling the air flow to Adjust the temperature of the semi-liquid metal in the intermediate container to the required temperature and prevent over-cooling, and then inject the semi-solid slurry in the intermediate container into the tilted cup upside down, so that the oxide layer can be retained in the cup. Surface to prevent it from entering the casting; then, the extrusion head presses the semi-solid slurry into the mold cavity to solidify under pressure to form the casting. The castings produced by this process have a denser structure and better properties than conventional squeeze casting, and can form thinner-walled castings.
Aluminum alloy liquid extrusion , aluminum alloy gravity casting, also known as liquid die forging, is an accurate shape casting technology that allows liquid or semi-solid metal to be filled and solidified under high pressure. This process effectively improves the casting shrinkage and forming capabilities, has the advantages of avoiding or reducing casting defects such as pores, improving the mechanical properties of the casting, a wide range of applications, and saving energy. At present, this process has been widely used in the production of important safety and high-performance parts such as automobiles and motorcycles in the world. It has important application prospects in the future when energy resources become increasingly tight and mechanical properties are increasingly required.
The improvement of squeeze casting equipment is an important condition for the promotion of squeeze casting technology. 、 At present, the company has automated low-pressure casting machines , 机以及200至630吨 Gravity casting machine and 200 to 630 tons 机等设备数十台，并配置完善光谱金相、X光透视等检测仪器；同时配套有多台机械加工设备来满足客户不同的加工需求。 There are dozens of equipments such as liquid extruder , and equipped with perfect detection instruments such as spectroscopic metallography, X-ray fluoroscopy, etc. At the same time, it is equipped with multiple mechanical processing equipment to meet customers' different processing needs. 9001:2000 、 ISO /TS 16949等质量体系等级认证。 The company has passed the national environmental protection acceptance of clean production enterprises and ISO 9001: 2000 , ISO / TS 16949 and other quality system level certifications. Squeeze casting machines have roughly developed into three categories: vertical mold clamping and vertical extrusion; horizontal mold clamping and horizontal extrusion; and horizontal mold clamping and vertical extrusion. The research and development of squeeze casting equipment is mainly focused on the following aspects: (1) Squeeze casting methods have gone from a traditional direct extrusion and indirect extrusion to a composite method, which has the advantages of both methods and forms a wider range of application. New extrusion casting process. For another example, it is integrated with the die casting and semi-solid casting methods to form an extrusion die casting process and a semi-solid extrusion casting. (2) The pouring method and the pouring system device focus on improving the pouring automation level and improving the pouring conditions, developing a high-precision hydraulic control valve and a closed-loop injection system, and establishing a dedicated and efficient pouring system. (3) The clamping force specifications are diversified, and the pressure control method of the injection system is improved to improve its control accuracy and stability, to achieve precise control of the extrusion process; to expand the range of equipment extrusion speed and extrusion pressure.
铸造新产品的开发，象山创亿金属有限公司均遵循如下方向：（1）取代常规的压铸工艺，使其有更致密的组织，可固溶热处理，并提高其力学性能或提高其耐磨性、抗渗漏性；（2）取代砂型、金属型铸造，使铸件内部组织更致密，表面轮廓更清晰，尺寸精度更高；（3）取代锻造、热挤压等工艺，以降低成本，简化工艺。 Regarding the liquid extrusion of aluminum alloys, gravity casting of aluminum alloys , and the development of new products for aluminum alloy low-pressure casting and casting, Xiangshan Chuangyi Metal Co., Ltd. all follow the following directions: (1) Replace the conventional die-casting process to make it have a denser structure, It can be solution heat treated and improve its mechanical properties or improve its wear resistance and leakage resistance; (2) Replace sand casting and metal casting to make the internal structure of the casting denser, the surface contour more clear, and the dimensional accuracy higher; 3) Replace forging, hot extrusion and other processes to reduce costs and simplify the process. In recent years, the research work on extrusion-cast aluminum-based composite materials has been very active in various countries in the world. Since extrusion-casting is the most inexpensive and suitable method for mass production of metal-based composites, it has attracted much attention. . 铸造产品的可以第一时间联系我司！ Hope that the majority of new and old customers need aluminum alloy liquid extrusion, aluminum alloy gravity casting, aluminum alloy low pressure casting and casting products can contact us as soon as possible!
