Titanium screw production process
Titanium screws are fasteners with excellent performance and are widely used in aerospace, shipbuilding, chemical equipment, medical equipment and other fields. The production process of titanium screws has an important impact on their quality and performance. The following introduces the production process of titanium screws.
The production process of titanium screws mainly includes raw material selection, processing and manufacturing, surface treatment and quality inspection.
The first is the selection of raw materials. The raw materials of titanium screws are mainly industrial pure titanium or titanium alloys. Industrial pure titanium has good forgeability and plasticity and is suitable for manufacturing conventional titanium screws. Titanium alloy has high strength and corrosion resistance, and is suitable for manufacturing titanium screws with special requirements. When selecting raw materials, it is necessary to select appropriate raw materials according to different application scenarios and requirements.
Processing and manufacturing is the core link of titanium screw production technology. First, a selected titanium material is cut, forged or drawn into the original shape of the stud. Next, the studs are threaded by turning, milling, boring, planing, etc., and the threads are heat treated to improve their hardness and strength. Finally, after polishing, cleaning and other processes, the final titanium screw product is obtained. During the entire 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 is a link that cannot be ignored in the production process of titanium screws. Surface treatment can improve the corrosion resistance, wear resistance and aesthetics of titanium screws. Common surface treatment methods include anodizing, electroplating, sand blasting, shot blasting, etc. Anodizing is to immerse titanium screws in an electrolytic bath containing acidic electrolyte. By applying electric current, an oxide film is formed on the surface of the screw to enhance the performance of the titanium screw. Its corrosion resistance. Electroplating is to immerse screws in an electrolyte containing metal ions and apply an electric current to deposit metal on the surface of the screw to improve its wear resistance. Sand blasting and shot blasting use high-pressure airflow or a sandblasting machine to spray abrasives onto the surface of screws to remove the surface oxide layer and dirt and improve their appearance.
The last step is quality inspection. The quality inspection of titanium screws includes appearance inspection, dimensional inspection, mechanical property testing, chemical composition analysis, etc. The appearance inspection mainly checks the surface smoothness, damage and oxide layer of the screws. Dimensional inspection is to determine whether the size of the screw meets the requirements by measuring the length, diameter, thread size and other parameters of the screw. Mechanical property testing mainly includes tensile, bending and hardness testing to evaluate the strength and hardness of screws. Chemical composition analysis tests the elemental composition of screws to ensure that their chemical composition meets standard requirements.
To sum up, the production process of titanium screws involves raw material selection, processing and manufacturing, surface treatment and quality inspection. Through scientific process control and strict quality inspection, titanium screw products with high quality and stable performance can be produced. With the further development of titanium alloy technology, the production process of titanium screws will continue to be improved and perfected to meet the needs of different fields.
