Mr Cao Jun said: "Compared with the traditional quantitative furnace, the new DOSOTHERM < DTI quantitative furnace can save up to 80% of the energy and 98% of the metal burning loss. The quantitative accuracy is as high as (+) 1%. It has outstanding performance in energy efficiency, metal burning loss, aluminum quality and quantitative accuracy."
Lightweight aluminum alloy shock absorber
Die castings with good physical and chemical properties, can be integrated into die casting molding, light weight and power "lightweight", more and more widely used in automotive parts. Automobiles, especially new energy vehicles, have a growing demand for vehicle weight loss. With aluminum instead of steel and casting instead of forging, by 2020, the total aluminum alloy consumption will be 200kg. The traditional shock absorption tower mainly adopts steel plate welding method, which has complex technology and low rigidity.
Integrated aluminum alloy shock absorber tower
In the first half of the year, Suzhou Huichi Light Alloy Precision Forming Technology Co., Ltd. successfully developed a lightweight aluminum alloy shock absorber, and in the "2018 China Die Casting Exhibition" on-site physical display. The absorber can satisfy the requirement of automobile lightweight and realize the "five in one" product integration design, the weight reduction effect reaches 40%; according to the material application demand, the high strength and toughness non-heat treatment die casting aluminum alloy material is successfully developed; the pouring system of special structure is designed to realize high density die casting. The tensile strength is 350MPa, the yield strength is 180MPa, and the elongation is 8-12%.
EM-K cold chamber die casting machine precipitated by technology for 15 years
Since its inception in 2003, Guangdong Baoyang Technology Co., Ltd. is committed to innovative die casting technology research and development and application, Mr. Ma Baoqing as the head of the enterprise, is also an expert in die casting machine design, for many years has been personally engaged in technology research and development. Guangdong Baoyang is "unique" in the design and manufacture of die casting machine, different structures, different designs, higher quality requirements, continuous optimization and upgrading of die casting machine products. In the "2018 China Die Casting Exhibition", Guangdong Bao Yang introduced the EM-K series cold chamber die casting machine that was precipitated for 15 years.

Eight axis linear robot
Hu Anxi, general manager of Rizhao, Shenzhen, said: "the eight axis linear robot we introduced is a die-casting linear robot with eight axis full servo parts and spray integrated design. It has dual functions of taking parts and spraying, and is more general than the general linear robot. The mobile arm of the spray task is more flexible and the spray is more thorough. The spray efficiency and quality are greatly improved, especially for deep cavity, core pulling and multi slide die casting, which improves the service life of die and the quality of die casting parts.
According to the introduction, the eight-axis spraying linear integration robot is the crystallization of technology accumulation and precipitation in Shenzhen Rizhao for many years. The technical team of the company has worked hard for more than one year to tackle key technical problems. The linear robot can realize four-axis and eight-axis linkage, run fast, work efficiently and work in all directions. High precision and high torque RV reducer is adopted in the rotation part of the linear robot gripper. The modular spray board assembly has its own rotation function, which can achieve the special requirements of side spraying and oblique spraying with the same function of the robot. Aiming at the core pulling die, the spray is achieved in all directions without dead angle. Modular spray head control system, spray head nozzle quantity can be left, right and bottom three directions expansion, can realize module block control. It can rapidly increase and reduce functions at any time.
