• Put the product into a salt spray test box, carry out a salt spray test, take out the product after 48 hours (which is equal to the normal time for three years), and then test the appearance and function of the product. Due to the current environment being different in each factory, a lot of safety padlocks are used in a high-corrosive and chemical environment. If you have any questions, please call us.

  • -55℃/-67℉ test Put the product into a high-low temperature cycle box, drop the temperature to -55℃/-67℉. Maintain the temperature for 24 hours, take out the product and then repeat 10 times, to test the function of the product. Put the product into a high-low temperature cycle box, raise the temperature to 55℃/131℉. Maintain the temperature for 24 hours, take out the product and then repeat 10 times, to test the function of the product. Due to the current environment being different in each factory, a lot of safety padlocks are used in the higher-temperature environment. If you have any questions, please call us.

  • Put the product into the UV and climatic test box, to simulate the damage to sunlight, moisture and temperature. Aging material includes fading, loss of gloss, strength reduction, cracking, peeling off, pulverization and oxidation. A few hours or days' testing in the simulation environment may cause damage for a few months or years. Then take it out to test the function of the product.
