Casting Services
Stainless steel casting is a manufacturing method that involves pouring molten stainless steel into a mold, allowing for the production of customized stainless steel components. We can provide a wide range of stainless steel casting services for many industries, such as construction machinery, ships, oil and gas, automobiles, or other large equipment industries.
Casting technology is an ancient and important metal processing technique that plays a crucial role in modern industrial production. The casting process is to heat a metal or alloy to a liquid state, and then inject it into a mold with the help of a mold or model. After the metal cools and solidifies, the desired shape and size of the product are obtained.
The casting process can be divided into several different types, such as pressure casting, gravity casting, sand casting, and lost wax casting. Each casting process has its unique advantages and scope of application. Pressure casting is suitable for producing high-precision and high-strength components, while sand casting is suitable for producing large and complex shaped castings.
In the casting process, the design and manufacturing of molds are crucial links. A suitable mold can ensure the quality and accuracy of castings, while also improving production efficiency and reducing production costs. Therefore, mold designers and manufacturers in the casting process need to have rich experience and technical knowledge.
In addition, the handling of metal liquids in casting processes is also a key issue. The temperature, composition, and processing method of metal liquids can all affect the quality and performance of castings. Therefore, in the casting process, the treatment technology of metal liquid is also crucial.
Casting process is a comprehensive technology that requires the combination of knowledge from multiple fields such as design, manufacturing, materials, chemistry, etc. With the development of modern industry, casting technology is constantly innovating and advancing, providing strong support for the development of various industries. I hope that through continuous research and practice, the casting process can be further developed and make greater contributions to human production and life.
The casting process is not fixed, and parts need to undergo a series of treatments after casting to ensure that their quality and performance meet the requirements.
Firstly, deburring treatment is required after the casting process. During the casting process, the metal liquid may form some burrs or uneven surfaces on the surface of the parts during the flow process. These burrs can affect the appearance and accuracy of the parts, and may even cause problems during use. Therefore, it is necessary to deburr these irregular surfaces to achieve a smooth and flat state.
Secondly, heat treatment is required after the casting process. Metals are subjected to stress and deformation during the casting process, and may also have some internal defects such as pores and inclusions. Through heat treatment, these internal stresses and defects can be eliminated, improving the hardness, strength, and corrosion resistance of the parts, while enhancing their overall performance, making them more suitable for practical use environments.
In addition, surface treatment is required after the casting process. Surface treatment can make the appearance of parts more beautiful, while also improving their corrosion resistance and wear resistance. Common surface treatment methods include sandblasting, painting, electroplating, etc. Different surface treatment methods can be selected according to the specific requirements and usage environment of the parts.
Although casting technology is an important manufacturing process, it still requires a series of treatments after casting to ensure that the quality and performance of the parts meet the requirements. Only by strictly controlling and handling every aspect can high-quality castings be produced to meet the needs of the market and customers.
Machining Services
Machining refers to the process of changing the shape, size, and surface quality of a workpiece by removing excess material from its surface. This process usually requires the use of equipment and tools such as machine tools, cutting tools, fixtures, as well as corresponding materials.
The application of machining in manufacturing is very extensive, involving almost all industrial fields. Let's take a look at the applications of machining in several major fields.
Mechanical manufacturing: Mechanical manufacturing is the main application field of machining. In the field of mechanical manufacturing, machining is used to manufacture various components or complete machines.
Construction industry: In the construction industry, machining is mainly used for manufacturing and processing building materials such as steel bars, cement, etc.
Automotive industry: In the automotive industry, machining is used to manufacture various components such as engines, transmissions, bearings, etc.
Aerospace industry: In the aerospace industry, machining is used to manufacture various high-precision and high-performance components, such as engine blades, wing beams, etc.
Electronics industry: In the electronics industry, machining is mainly used to manufacture various precision parts and components, such as mobile phone parts, computer accessories, etc.
Mechanical machining accuracy is mainly used to characterize the precision of produced products and is a term for evaluating the geometric parameters of machined surfaces. There are a total of 20 tolerance levels from IT01, IT0, IT1, IT2, IT3 to IT18. Among them, IT01 indicates that the machining accuracy of the component is the highest, and T18 indicates that the machining accuracy of the component is the lowest. Generally, factory and mining machinery belongs to IT7 level, and general agricultural machinery belongs to IT8 level. According to different functions, product components need to achieve different machining accuracies, and different machining forms and processes need to be selected.
CNC Lathe Machining
CNC lathe is one of the widely used CNC machine tools. It is mainly used for cutting the inner and outer cylindrical surfaces of shaft or disc parts, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer surfaces, and cylindrical and conical threads. It can also perform cutting, drilling, expanding, reaming, and boring.
Due to the high precision of CNC lathe machining, as well as its centralized Machining Process and low number of parts clamping, higher requirements are placed on the CNC cutting tools used。
The normal use of CNC lathes must meet the following conditions: the power supply voltage fluctuation at the location of the machine tool is small, the ambient temperature is below 30 degrees Celsius, and the relative temperature is less than 80%.
Environmental requirements
The position of the machine tool should be far away from the vibration source, avoid direct sunlight and thermal radiation, and avoid the influence of moisture and airflow. If there is a vibration source near the machine tool, anti vibration grooves should be set up around the machine tool. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, causing poor contact of electronic components, resulting in malfunctions and affecting the reliability of the machine tool.
Power requirements
Generally, CNC lathes are installed in machining workshops, which not only have large temperature changes and poor operating conditions, but also have various mechanical and electrical equipment, resulting in large fluctuations in the power grid. Therefore, the installation position of the CNC lathe requires strict control of the power supply voltage. The fluctuation of power supply voltage must be within the allowable range and remain relatively stable. Otherwise, it will affect the normal operation of the CNC system.
Temperature conditions
The ambient temperature of the CNC lathe is below 30 degrees Celsius, and the relative temperature is less than 80%. Generally speaking, there are exhaust fans or air coolers inside the CNC control box to maintain a constant operating temperature or minimal temperature difference of electronic components, especially the central processing unit. Excessive temperature and humidity will reduce the lifespan of control system components and lead to an increase in malfunctions. The increase in temperature and humidity, as well as the increase in dust, can cause adhesion on the integrated circuit board and lead to short circuits.
Standardize the use of machine tools
Users are not allowed to arbitrarily change the parameters set by the manufacturer in the control system when using the machine tool. The setting of these parameters is directly related to the dynamic characteristics of various components of the machine tool. Only the gap compensation parameter values can be adjusted according to the actual situation.
Users are not allowed to replace machine accessories at will, such as using hydraulic chucks that exceed the specifications in the manual. When setting up attachments, the manufacturing plant fully considers the matching of various process parameters. Blind replacement can cause mismatches in various parameters and even result in unforeseeable accidents.
The pressure of hydraulic chuck, hydraulic tool holder, hydraulic tailstock, and hydraulic cylinder should be within the allowable stress range and should not be arbitrarily increased.
