Casting machine tools refer to machine tools used to manufacture castings, and their bodies are usually made through casting processes. The following are the general steps of the casting process of general casting machine tool bodies: 1. Design the mold: First, according to the design requirements of the casting machine tool, the detailed design and size specifications of the body are formulated. Then, the mold of the body is made according to the design requirements, and high-strength casting sand is usually used to make the mold. 2. Prepare the mold: Place the prepared mold on the casting machine and ensure that the position of the mold in the machine is accurate. At the same time, prepare the required casting materials, usually metal alloys. 3. Preheat the mold: Before the actual casting operation, the mold usually needs to be preheated. The purpose of preheating is to improve the heat resistance and ductility of the mold so that it can better accommodate the molten metal. 4. Prepare the molten metal: Put the appropriate metal material into the furnace, heat it and melt it. The heating temperature depends on the metal material used. 5. Pouring: When the metal melts and reaches the appropriate temperature, pour the molten metal from the furnace into the pre-prepared mold. During the pouring process, care should be taken to avoid bubbles and impurities. 6. Cooling and solidification: After pouring, the metal is allowed to cool and solidify in the mold. The cooling time depends on the metal used and the size of the casting. 7. Demolding: Once the casting is completely cooled, the mold can be removed from the casting. Special tools and equipment are usually used for demolding. 8. Cleaning and finishing: After removing the mold, the casting is cleaned and finished. It may be necessary to remove oxides, burrs or other defects on the surface of the casting. 9. Post-processing: The casting is further processed and treated as needed, such as heat treatment, surface treatment, etc. These are the general casting process steps for the casting machine tool body. The specific details and processes may vary depending on the specific body design and casting process requirements.

Sand casting is a common metal casting method with the following advantages and disadvantages: advantage: 1. Simple equipment: Compared with other casting methods, sand casting has relatively low equipment requirements and low cost. 2. Wide range of materials: Sand casting can be used for many different types of metals, including iron, aluminum, copper, etc. 3. Manufacturing flexibility: Sand casting can manufacture parts of various shapes and sizes, including simple and complex geometries. 4. Cost-Effectiveness: Sand casting is a cost-effective method for low to medium quantity part production. 5. Scalability: Sand casting can easily adapt to changes in output, increasing or decreasing production quantities according to demand. shortcoming: 1. Limited surface quality: Since some marks and blisters will be left on the surface of the sand mold, the surface quality of sand cast parts is usually rough and requires further processing and treatment. 2. Low dimensional accuracy: Due to the expansion and contraction of the sand mold, the dimensional accuracy of sand casting is usually low, making it difficult to obtain very accurate dimensions. 3. Long production cycle: Compared with some other casting methods, the cycle of making a sand mold and casting is usually longer, and it takes a certain amount of time to prepare and process the sand mold. 4. Limit complexity: Although sand casting can manufacture parts of various shapes, its applicability is limited for parts with very complex geometries or complex internal structures. 5. Environmental impact: A large amount of sand dust and waste sand are generated during the sand casting process, and smoke and waste gas will be generated during metal melting and processing. Appropriate environmental protection measures are required. In summary, sand casting has certain advantages when producing metal parts with simple shapes and medium quantities, but it may not be suitable when high precision, complex shapes or mass production are required.

The manufacturing process of machine tool castings usually includes the following steps: Design and mold manufacturing: First, design the casting to determine the shape, size and material of the casting. The mold used to produce the casting is then made, usually using a sand mold, a metal mold, or a permanent mold. Melting metal: Select appropriate metal materials, such as iron, aluminum, brass, etc., and heat them to the melting point to form molten metal. Prepare the sand mold: Use a mold to pour molten metal into the sand mold. A sand mold can be a dedicated mold for a single casting or a continuous mold for continuous casting. Pouring and Solidification: Molten metal is poured into a sand mold, filling the entire cavity. After the metal cools and solidifies, the initial shape of the casting is obtained. Mold separation: After cooling and solidification, the mold is disassembled from the casting to obtain the initial casting. Remove burrs and defects: Deburr and trim the initial castings to remove possible defects such as sand cores, pores, inclusions, etc. to ensure the quality of the castings. Finishing: Further processing operations such as milling, drilling, threading, etc. are performed on the casting as needed to meet the requirements of the final product. Surface treatment: Perform necessary surface treatment on castings, such as polishing, painting, plating, etc., to improve appearance quality and corrosion resistance. Inspection and quality control: Conduct various inspections and tests on castings, such as dimensional measurement, material analysis, non-destructive testing, etc., to ensure that the castings meet design requirements and quality standards. Final product: After the above steps, a machine tool casting that meets the requirements is obtained, which can be assembled and put into use. It should be noted that the specific steps and methods of the machine tool casting manufacturing process may vary depending on the shape, size, material and production equipment of the casting.

Today, I will share a dry casting process and learn about a variety of casting types. What is casting? Liquid metal is poured into the mold cavity suitable for the shape and size of the part, and cooled and solidified to obtain a blank or part, which is usually called liquid metal forming or casting. Sand casting: casting method for producing castings in sand mold. Steel, iron and most nonferrous alloy castings can be obtained by sand casting. Used in automobile engine cylinder block, cylinder head, crankshaft and other castings. Investment casting is applied to the production of small parts with complex shapes, high precision requirements or difficult other processing, such as blades of turbine engines. Pressure casting, application: Die casting was first used in automobile industry and instrument industry, and then gradually expanded to various industries, such as agricultural machinery, machine tool industry, electronics industry, national defense industry, computers, medical devices, clocks, cameras and daily hardware. Low pressure casting, used in: mainly traditional products (cylinder head, wheel hub, cylinder frame, etc.) Centrifugal casting, application: centrifugal casting was first used to produce cast pipes, and centrifugal casting technology was used to produce steel, iron and non-iron carbon alloy castings in metallurgy, mining, transportation, irrigation and drainage machinery, aviation, national defense, automobile and other industries at home and abroad. Among them, centrifugal cast iron pipe, cylinder liner and shaft sleeve of internal combustion engine are the most common castings. Metal mold casting is applied to: metal mold casting is suitable for mass production of non-ferrous alloy castings such as aluminum alloy and magnesium alloy with complex shapes, and also suitable for the production of steel and metal castings and ingots. Squeeze casting can be used to produce various types of alloys, such as aluminum alloy, zinc alloy, copper alloy and ductile iron. Lost foam casting is applied to: it is suitable for producing various precision castings with complex structure, and there is no limit on alloy types and production batch. Such as gray cast iron engine box, high manganese steel elbow, etc. Continuous casting is applied to: long castings with constant cross-section shapes such as steel, iron, copper alloy, aluminum alloy and magnesium alloy can be poured by continuous casting, such as ingots, slabs, bars and tubes.

When we cast casting products, we will consider that the wall thickness of the casting should be as uniform as possible, the transition of sections of different sizes should be reasonable, the walls should not be connected at sharp angles, the rounded corners of the castings should not have sharp corners, and the minimum casting aperture should be reasonable. The structure should be as simple as possible, have a reasonable draft angle, and reduce the parting surface and core. The thickness and distribution of stiffeners should be reasonable, and lugs, bosses, cantilever brackets and other castings with protruding parts should be designed to allow free removal of the mold from the mold. When welding, the weld seam should be easy to operate, which is beneficial to reducing welding stress and deformation. The maximum stress should be avoided, and the stress should be concentrated on the processed surface. When welding, only by selecting the form, position and size of the welding joint to meet the corresponding requirements can we ensure the quality of the welding. When performing heat treatment, we will first check whether there are sharp corners, sharp changes and closed holes in the product. For large and long parts, the convenience of heat treatment, clamping and hanging should be considered when designing. During cutting, the parts should have reasonable process standards and surfaces with mutual position requirements. We will complete the processing in one clamping. The process standards and design standards of the parts we process are consistent. During assembly and maintenance, we will consider the processability of the thread and the reliability of the seal. When performing pressure processing, it is divided into forging parts, blanking parts, bent parts, deep drawing parts, fine blanking parts, and cold extrusion parts.The picture below is a picture of some casting products we make. We make every item with care and attention, and choosing us is the most correct decision.

The customized large castings that have been prepared are being prepared for inspection and then loaded for shipment. Large castings refer to larger and heavier cast parts. They are usually used in engineering and heavy industry fields that require special requirements such as high strength, wear resistance, and corrosion resistance The manufacturing of large castings requires the use of advanced casting processes and equipment, as well as high requirements for material mechanical properties, thermal properties, and corrosion resistance.

These molds are typically made from heat-resistant materials that can withstand the pressure and heat of the high-temperature support metal. 3. Melting: The selected material will be melted into rabbits with precise control based on the required alloy composition and temperature. This process is usually done in a furnace or electric arc furnace. 4. Casting: After the converter material reaches the appropriate temperature and fluidity, it will be made into a good mold. The shape inside the mold determines the shape of the final casting. 5. Cooling and solidification: The mold material in the mold is cooled and solidified inside the mold to make a strong casting. 6. Removal and post-processing: Once the casting is completely cooled, it is removed from the mold and processed. This may include processes such as grinding, cleaning, cutting, painting, heat treating and quality inspections to ensure that the castings meet the required quality standards. 7. Quality control: Casting factories must carry out quality control to ensure that castings meet specifications and standards. This may involve material testing, dimensional inspection, non-destructive inspection, chemical analysis and mechanical property testing, etc.
