Titanium screws are a type of fastener with excellent performance and are widely used in aerospace, shipbuilding, chemical equipment, medical devices and other fields. Titanium screws, as key fasteners, their performance is directly related to the reliability and safety of equipment in aerospace, medical devices, Marine engineering and other fields. Therefore, the production process of titanium screws has a significant impact on their quality and performance.
The production process of titanium screws mainly includes raw material selection, processing and manufacturing, surface treatment and quality inspection, etc.
Raw material selection
The raw materials of titanium screws are mainly industrial pure titanium or titanium alloys. Industrial pure titanium has excellent forgeability and plasticity and is suitable for manufacturing conventional titanium screws. Titanium alloys have high strength and corrosion resistance, and are suitable for manufacturing titanium screws with special requirements. When selecting raw materials, it is necessary to choose appropriate raw materials according to different application scenarios and requirements.
Processing and manufacturing
Processing and manufacturing is the core link in the production process of titanium screws. First, the selected titanium material undergoes processing techniques such as cutting, forging or drawing to form the initial shape of the studs. Next, the studs are processed by turning, milling, boring, planing, etc., to produce threads, and the threads are heat-treated to enhance their hardness and strength. Finally, after processes such as polishing and cleaning, the final titanium screw product is obtained. Throughout the entire processing and manufacturing process, parameters such as heating temperature and deformation speed need to be strictly controlled to ensure the quality and performance of titanium screws.
Surface treatment
Surface treatment is an indispensable link in the production process of titanium screws. Surface treatment can enhance the corrosion resistance, wear resistance and aesthetic appeal of titanium screws. Common surface treatment methods include anodizing, electroplating, sandblasting, shot peening, etc. Anodizing involves immersing titanium screws in an electrolytic cell containing acidic electrolyte and applying an electric current to form an oxide film on the surface of the screws, enhancing their corrosion resistance. Electroplating involves immersing screws in an electrolyte containing metal ions. By applying an electric current, the metal is deposited on the surface of the screws, enhancing their wear resistance. Sandblasting and shot blasting involve using high-pressure air flow or a sandblasting machine to spray abrasive materials onto the surface of screws, removing surface oxide layers and dirt to enhance their aesthetic appeal.
Quality inspection
The quality inspection of titanium screws includes appearance inspection, dimensional detection, mechanical property testing, chemical composition analysis, etc. The visual inspection mainly checks the surface finish of the screws, the absence of damage and the condition of the oxide layer. Dimensional inspection is carried out by measuring parameters such as the length, diameter, and thread size of a screw to determine whether its dimensions meet the requirements. Mechanical property tests mainly include tensile, bending and hardness tests, etc., which are used to evaluate the strength and hardness of screws. Chemical composition analysis is carried out by testing the elemental composition of screws to ensure that their chemical composition meets the standard requirements.
In conclusion, the production process of titanium screws involves raw material selection, processing and manufacturing, surface treatment and quality inspection, etc. Through scientific process control and strict quality inspection, titanium screw products with excellent quality and stable performance can be produced. With the further development of titanium alloy technology, the production process of titanium screws will also be continuously improved and perfected to meet the demands of different fields.
