? As an important basic equipment of modern manufacturing industry, Casting Machinery is widely used in automobile, aerospace, energy, machinery manufacturing and other fields. With the continuous progress of industrial technology, the types and functions of casting machinery are also increasingly rich. This article will introduce the common types of casting machinery and its application scenarios, to help readers fully understand the status of technological development in this field.

?

First, sand casting equipment?

Sand casting is one of the most traditional casting methods, and its core equipment includes sand mixer, molding machine and sand falling machine. Sand mixer for the sand, binder and other additives evenly mixed to form a suitable sand molding. Modern sand mixing machine has realized automatic control, can precisely adjust the proportion and mixing time. The molding machine is the mixed sand pressed into the casting equipment, according to the process can be divided into vibration pressure, injection pressure and static pressure and other types. Among them, the static pressure molding machine is gradually becoming the mainstream choice because of its low noise, low energy consumption and other characteristics. Sand fall machine is used to separate the castings from the sand mold, vibration sand fall machine and drum sand fall machine are two common forms.

Second, metal casting equipment?

metal casting, also known as permanent casting, the main equipment includes metal Casting Machine and melting furnace. Metal casting machine is usually equipped with open and close type mechanism, ejector mechanism and cooling system, can realize rapid cycle production. This type of equipment is particularly suitable for mass production of non-ferrous castings of simple shapes, such as aluminum alloy wheel hubs, engine cylinder heads, etc.. Modern metal casting machine commonly used PLC control, realizing the precise adjustment of process parameters and automated monitoring of the production process.

Third, pressure casting equipment?

pressure casting is the molten metal under high pressure to quickly fill the mold cavity process, the main equipment is die casting machine. According to the clamping force size, die casting machine can be divided into small (<1000 tons), medium-sized (1000-4000 tons) and large (>4000 tons) three categories. Cold chamber die casting machine is suitable for aluminum alloy, magnesium alloy and other high melting point metal, and hot chamber die casting machine is mainly used for zinc alloy and other low melting point metal die casting. In recent years, vacuum die casting, semi-solid die casting and other new technology development, further expand the scope of application of die casting technology.

Fourth, centrifugal casting equipment?

Centrifugal casting is the use of centrifugal force generated by the rotation of the metal liquid filling casting special process, the main equipment is centrifugal casting machine. According to the direction of the rotation axis can be divided into horizontal and vertical two kinds. Horizontal centrifugal casting machine is suitable for the production of tubular castings, such as cast iron pipe, cylinder liner, etc.; Vertical centrifugal casting machine is mostly used for the production of wheel hubs, flanges and other disk castings. Modern centrifugal casting machine is equipped with a precise speed control system and temperature monitoring device to ensure the stability of casting quality.

Fifth, investment casting equipment?

investment casting, also known as lost wax casting, its equipment system is more complex, including mold making machine, shell production line, dewaxing equipment and roasting furnace. Mold making machine for the production of wax mold or 3D printing mold, modern equipment has achieved a high degree of automation. The shell production line forms multi-layer ceramic shells on the surface of wax molds through dipping, sanding and drying. Dewaxing equipment removes the wax from the molds using steam or high-temperature baking, and roasting ovens heat the shells to a predetermined temperature to increase their strength. Investment casting is particularly suitable for the production of complex shapes, precise size of the castings, such as turbine blades, works of art.

Six, continuous casting equipment?

Continuous casting is the molten metal continuously poured into the water-cooled crystallizer to form an infinitely long casting billet process, the main equipment, including intermediate packages, crystallizer, billet pulling machine and cutting device, etc.. Slab continuous casting machine and billet continuous casting machine widely used in the iron and steel industry belongs to this kind. Non-ferrous metal continuous casting equipment is mostly used for the production of bar, pipe and wire. Modern continuous casting equipment to realize the full automation control, and rolling equipment directly connected to form a highly efficient production line.

?

Seven, special casting equipment?

With the continuous emergence of new materials, some special casting equipment also came into being. Vacuum casting equipment by pouring in a vacuum environment, reducing metal oxidation and gas inclusions; directional solidification equipment for the production of castings with a specific crystal organization, such as single-crystal turbine blades; electromagnetic casting equipment using electromagnetic force to control the flow of liquid metal to improve the surface quality of castings. These special equipment, although the scope of application is relatively limited, but in the field of high-end manufacturing plays an irreplaceable role.

?

Eight, auxiliary equipment?

complete casting production line also includes many auxiliary equipment, such as melting furnace, pouring machine, cleaning equipment, testing instruments. Medium-frequency induction furnace is widely used in metal melting because of its high heating efficiency, precise temperature control; automatic pouring machine through the robot or robot to achieve precise pouring, improve production safety; shot blasting machine for the removal of casting surface oxidation and burrs; X-ray flaw detector, ultrasonic detector and other equipment is used for casting the detection of internal defects.

?

Nine, the development trend of intelligent?

Currently, casting machinery is moving towards intelligent, green direction. Intelligent casting equipment integrated Internet of things, big data and artificial intelligence technology, realizing the real-time monitoring and optimization of the production process. For example, intelligent die casting machine can automatically identify the mold state and adjust the process parameters; adaptive control system can automatically optimize the pouring scheme according to the casting quality feedback. At the same time, energy saving and environmental protection type equipment is also more and more attention, such as waste heat recovery system, exhaust gas treatment device has become the standard of modern foundry.

?

Ten, selection and application recommendations?

In the selection of casting machinery, need to take into account product characteristics, production batch, quality requirements and investment budget and other factors. Mass production should choose a high degree of automation of the die-casting machine or metal casting machine; small quantities of complex parts can be considered investment casting or sand casting; special alloy castings may require vacuum casting equipment. At the same time, the reliability of the equipment, maintenance convenience and energy consumption indicators should also be included in the assessment.

?

In short, a wide range of casting machinery, each with its own characteristics. With the in-depth implementation of the "Made in China 2025" strategy, domestic casting equipment in terms of precision, reliability and level of intelligence have made great progress for the high-quality development of manufacturing industry to provide strong support. In the future, with the emergence of new materials, new processes, casting machinery will continue to innovate and promote the casting industry to more efficient, more precise, more environmentally friendly direction.
