kaj je tlačno litje v hladni komori? In zakaj se pogosto uporablja v industriji tlačnega litja?

Cold-chamber die-casting is that the robotic arm pours the molten metal liquid into the injection chamber by feeding the soup from the middle of the machine through a spoon, and then uses the injection piston (hammer) to push the metal liquid into the mold at high speed, while maintaining a certain pressure. A casting equipment that cools and solidifies to obtain finished products. His advantage is that it does not need manual reclaiming and has a high degree of automation. The surface of the die-cast product is smooth and flat, with high strength and hardness, and the thickness of the product is thin. The products made do not need secondary processing, but one-time molding, which can realize the industrialization and integration of production, so as to achieve the effect of reducing cost and increasing efficiency.

Our factory currently has 21 cold-chamber die-casting machines with a maximum volume of 3,000 tons, which can be used for die-casting large structural parts, such as automobile gearboxes, mechanical casings, etc. Recently, the world’s first 27.5-inch, super-sized magnesium alloy frame built by our company with 3,000 tons of equipment won the Excellence Award at the 79th World Magnesium Association Conference in 2022. The International Magnesium Association (IMA) was founded in 1943 with the mission to promote the use of metallic magnesium in material selection and to encourage innovative applications of multifunctional metals. Established in 1962, IMA’s Excellence Awards program is an annual selection competition open to all companies in the industry to showcase magnesium’s role in the five categories of automotive foundry products/non-automotive commercial foundry products/design forged products/environmental protection/health and safety Outstanding applications in each aspect, and select the most representative outstanding products of the year from the above five aspects.

We have used this process to cooperate with well-known car companies such as Mercedes-Benz, Ford, BYD and other auto parts such as steering wheels, gearboxes and other auto parts, as well as Yadi, Emma, Mavericks, Xidesheng and other two-wheeled vehicle frames and axles. The one-piece molding process we do makes these products very simple and beautiful in appearance without welding ports.

Cold chamber die casting is currently the most widely used alloy die casting process on the market, and our company is very mature in this application.
