Titanium capillary production process
Titanium capillary, as a special tube with excellent corrosion resistance, high strength and low density, is widely used in aerospace, medical equipment, chemical engineering and other fields. The production process of titanium capillary is not only related to the quality and performance of the product, but also directly affects the final market competitiveness. Haiboweier editor will explore in depth the various links of the titanium capillary production process in this article to help everyone better understand the manufacturing process of this high-tech material.
Material preparation
The main raw material for the production of titanium capillary is high-purity titanium powder. The quality of titanium powder has a vital influence on the final performance of the capillary. Therefore, in the material preparation stage, it is necessary to strictly screen the titanium powder to ensure that its purity and particle size meet the production requirements. At the same time, in order to avoid the influence of impurities on product quality, the titanium powder needs to be cleaned and dried.
Molding
Molding is one of the key steps in the production of titanium capillary. At present, the commonly used molding methods mainly include compression molding and injection molding. Among them, injection molding is widely used because of its simple operation and high molding quality.
During the molding process, it is necessary to accurately control the molding parameters such as mold temperature, injection pressure, injection speed, etc. according to the specifications and requirements of the titanium capillary. The control of these parameters has an important influence on the shape, size and surface quality of the titanium capillary.
Sintering
Sintering is the process of heat treating the formed titanium capillary at high temperature to form a dense titanium alloy layer. This step is intended to improve the hardness, density and toughness of the titanium capillary.
During the sintering process, the sintering temperature and time need to be strictly controlled. Too high sintering temperature or too long time may cause the titanium capillary to be over-sintered, thereby affecting its performance; while too low sintering temperature or too short time may lead to insufficient sintering, affecting the density and strength of the capillary.
Post-processing
After sintering, the titanium capillary needs to undergo a series of post-processing operations to improve its surface quality and performance. These post-processing operations mainly include cleaning, polishing and inspection.
Cleaning: Remove impurities such as oxides and oil stains on the surface of the titanium capillary to ensure its surface quality.
Polishing: Make the surface of the titanium capillary smooth and improve its appearance quality. During the polishing process, it is necessary to select appropriate polishing agents and polishing tools, and accurately control the polishing time and strength.
Inspection: Perform appearance inspection and quality inspection on the titanium capillary to ensure that it meets the specifications and requirements. Common inspection methods include ultrasonic flaw detection, penetrant color flaw detection, etc.
Quality inspection
In the production process of titanium capillaries, quality inspection is an important link to ensure product quality. Quality inspection mainly includes appearance inspection, dimensional measurement, performance testing, etc.
Appearance inspection: Check the surface quality of the titanium capillary, such as whether there are defects such as cracks, bubbles, inclusions, etc. on the surface.
Dimension measurement: Measure the diameter, wall thickness and other dimensional parameters of the titanium capillary to ensure that it meets the specification requirements.
Performance test: Perform performance tests such as hardness, density, and toughness on the titanium capillary to ensure that it meets the use requirements.
The production process of titanium capillaries is a complex and delicate process, which requires strict control of the process parameters and operation procedures of each link. Only when certain requirements are met in material preparation, molding, sintering, post-processing and quality inspection, can high-quality titanium capillary products be produced.
