Product Overview
Optical communication cavity titanium alloy lost wax casting parts are cavity type components manufactured using titanium alloy as raw material and lost wax casting technology for the field of optical communication. Optical communication is an important component of modern communication, which requires extremely high precision, performance, and stability of components. Titanium alloy has the advantages of low density, high strength, and corrosion resistance, making it very suitable for manufacturing parts with demanding performance requirements such as optical communication cavities. The lost wax casting process can achieve precise shaping of complex shapes, meeting the design requirements of optical communication cavities.
Material Properties
High strength
Titanium alloy has high strength, which can ensure the structural integrity of the optical communication cavity in various environments, and is not easily deformed or damaged. This is crucial for the long-term stable operation of optical communication equipment, as even small deformations in the cavity can affect the position and performance of internal optical components, thereby affecting the transmission quality of optical signals.
Low density
Compared to other metal materials, titanium alloy has a lower density, making the overall weight of the optical communication cavity lighter. This has obvious advantages in some application scenarios that have strict requirements for equipment weight, such as optical communication equipment in the aerospace field. Reducing weight can reduce energy consumption, improve equipment portability, and installation efficiency.
Corrosion resistance
Titanium alloy has good corrosion resistance and can resist the erosion of environmental factors such as moisture and chemicals. Optical communication chambers usually need to work in different environments and may come into contact with various corrosive substances such as moisture, salt spray, etc. The corrosion-resistant property can extend the service life of the cavity and reduce maintenance costs.
Biocompatibility
Although biocompatibility is not a major consideration in the field of optocommunication, in some special applications such as medical optical communication equipment, the biocompatibility of titanium alloys can avoid adverse effects on the human body, ensuring the safety and reliability of the equipment.
Lost wax casting process
Making wax molds: First, make wax molds based on the design drawings of the optical communication cavity. The precision of wax mold production directly affects the dimensional accuracy and surface quality of the final castings. Usually, high-precision mold injection molding technology is used to inject wax into the mold, forming a wax mold that is consistent with the shape of the optical cavity. During the production process, it is necessary to strictly control the temperature, pressure, and injection speed of the wax material to ensure the dimensional accuracy and surface smoothness of the wax mold.
Module assembly: Connect multiple wax molds together through a gating system to form a module. The design of the sprue system should be reasonable, ensuring that the metal liquid is evenly filled into each wax mold during the casting process, avoiding defects such as porosity and shrinkage. The assembly of the module should be firm to prevent the wax mold from falling off or shifting during subsequent operations.
Shell making: Immerse the module in a specially made fire-resistant coating, then sprinkle fire-resistant sand and repeat multiple times to form a certain thickness of shell. The strength and breathability of the shell have a significant impact on the quality of casting. Insufficient strength may cause the shell to crack during the casting process, while poor breathability can affect the filling of molten metal and the discharge of gas, resulting in defects such as pores. Therefore, it is necessary to choose appropriate refractory materials and shell making processes to control the thickness and density of the shell.
Dewaxing: Place the module with a shell into a steam dewaxing kettle, melt the wax mold with high-temperature steam, and discharge it to form a mold cavity. The dewaxing process should be thorough to ensure that there is no residual wax material in the mold cavity, otherwise it will affect the quality of the castings. At the same time, attention should be paid to controlling the temperature and time of dewaxing to avoid cracking of the shell due to excessive temperature.
Melting and pouring: Place titanium alloy raw materials into a vacuum induction melting furnace for melting to ensure uniform alloy composition. During the melting process, it is necessary to strictly control the melting temperature and time to avoid the burning of alloy elements and the mixing of impurities. After the alloy reaches the appropriate temperature and flowability, it is poured into the preheated shell. The pouring process should be rapid and smooth, avoiding splashing and oxidation of the molten metal.
Cooling and cleaning: After pouring is completed, let the casting naturally cool in the mold shell. The cooling rate has an impact on the microstructure and properties of castings, and it is necessary to control the cooling rate reasonably based on the characteristics of titanium alloys and factors such as the size and shape of castings. After cooling, remove the mold shell, clean and polish the castings, and remove impurities such as burrs and oxide scales on the surface.
quality control
Dimensional accuracy testing
Use high-precision measuring equipment, such as a coordinate measuring instrument, to test the dimensions of the optical communication cavity castings to ensure they meet the requirements of the design drawings. The deviation in dimensional accuracy may affect the assembly and fit of the cavity with other components, thereby affecting the performance of optical communication equipment. Therefore, it is necessary to strictly control the dimensional tolerances and correct or scrap castings that do not meet the requirements.
Surface quality inspection
By visual inspection, metallographic microscope and other methods, the surface quality of castings is checked, including surface roughness, pores, cracks and other defects. Poor surface quality may affect the appearance and performance of the optical communication cavity, for example, surface pores may affect the sealing of the cavity, and cracks may cause the casting to fracture during use. For castings with surface quality that does not meet the requirements, repair or reprocessing is necessary.
Internal quality inspection
Non destructive testing methods such as X-ray inspection, ultrasonic inspection, etc. are used to detect whether there are defects such as pores, shrinkage porosity, inclusions, etc. inside the castings. Internal defects can reduce the strength and reliability of castings, affecting the long-term stable operation of optical communication equipment. For castings with internal defects detected, it is necessary to evaluate the nature and severity of the defects and decide whether to repair or scrap them.
Performance testing
Testing the mechanical properties, corrosion resistance, etc. of castings to ensure that they meet the requirements for the use of optical communication chambers. Mechanical performance testing includes tensile testing, hardness testing, etc. Corrosion resistance testing can be conducted through methods such as salt spray testing. Only castings that meet the required performance indicators can be put into use.
