Hardware shielding cover manufacturers, the reasons for the yellowing of the shielding cover + 16 strict quality inspections

Manufacturers of hardware shielding covers often encounter yellowing of the surface in our actual applications. It seriously affected the appearance, quality, and use of customers. Xiaoshuo has compiled the following information and will work with you to understand what causes the yellowing of the shielding cover: 1. The raw materials of the shielding cover are not properly controlled in the production of the shielding cover, so that the material of the shielding cover, before the production, the foreign cupronickel material is already natural Oxidation produces a yellowing phenomenon. 2. The cleaning of the shielding cover after production, the improper combination of the cleaning solution prescription, resulting in a chemical reaction to the nickel silver material, causing the shielding cover to turn yellow. 3. In the soldering process of the SMT factory, some formulas are not matched properly, which causes the yellowing of the surface of the shielding cover when the shield is over the furnace at high temperature. 4. The storage environment is not up to standard. In general, metal materials will have natural oxidation. If the storage environment is not up to standard, it will accelerate the oxidation of the shielding cover, thereby accelerating the yellowing of the shielding cover. Hardware, 15 years of focus on hardware shielding manufacturers, 20,000+ sets of mold customization production experience, 2 days for proofing, 4 days for mold making and 2 days for delivery. The flatness of the shielding cover is controlled within 0.07mm, the daily production capacity is 3 million strokes, and 16 quality inspections are strictly controlled. It can quickly solve the urgent problem of time when choosing the shielding cover, solve the problem of flatness, solve the problem of production quality, let you choose, choose to rest assured!
