Key methods to prevent iron screws from rusting and pay attention to precision screw customization
To prevent iron screws from rusting, there are several key points to note:
1. Reduce the contact between metal accessories and humid environments: Try to avoid dust particles or other impurities from adhering to the surface of iron screws in humid climate conditions to prevent the occurrence of electrochemical corrosion.
2. Avoid the attachment of organic acids: Substances containing acidic components such as organic juice will cause corrosion reactions when they come into contact with the surface of iron screws. Therefore, attention should be paid to timely cleaning and preventing such substances from adhering to the screws for a long time.
3. Protect the ribbed surface: For iron screws with ribbed surfaces, avoid exposure to alkaline water or salty environments to avoid partial corrosion.
4. Prevent chemical corrosion: Pay attention to the impact of air pollutants on iron screws, especially solutions containing sulfuric acid, nitric acid and acetic acid, and try to avoid long-term exposure of screws to these environments.
Precision screws are tiny fasteners that play a key role in products despite their small size. In the process of customizing precision screws, you need to pay attention to the following points:
1. Determine the appearance and specifications of the screws according to product requirements: According to the use environment and requirements of the product, determine the specifications, size, head shape, groove type, material and surface treatment method of the precision screws.
2. Provide customized drawings: Provide customized drawings of precision screws to manufacturers, clearly specifying the dimensions and requirements of each part. If drawings cannot be provided, the relevant requirements for the products used for non-standard screws can be provided, and the manufacturer can design according to the actual situation.
3. Sample production and confirmation: The manufacturer produces samples according to the design drawings and conducts inspection and confirmation. If mold production is required, the manufacturer will entrust a mold maker to make the mold.
4. Mass production: After the sample is confirmed to be correct, the manufacturer will carry out mass production and install the screws on the product for adaptation testing. After confirming that the mass-produced screws meet the requirements, mass production will begin.
The above are the key methods to prevent iron screws from rusting and to pay attention to during the customization process of precision screws. Through reasonable protection and customization processes, the quality and performance of the screws can be ensured, and the reliability and service life of the products can be improved.
