Common rubber mold cleaning methods

1. Chemical cleaning, use professional mold washing water, or diluted sulfuric acid to directly clean the scaled parts. This method is fast and the effect is also acceptable, but it will produce pungent odors during cleaning, and it will also pollute the environment. This method has been gradually eliminated, and some small processing plants are still in use.

2. Mechanical descaling. At present, most rubber product manufacturers are equipped with sandblasting machines, which can directly blast the surface of the mold with resin sand. This method has a better cleaning effect and is a more commonly used method of mold cleaning.

3. Ultrasonic descaling, using the principle of frequency and wavelength to shake off the dirt in the mold cavity. The effect is better when used with mold washing water. This effect is very good, but the cost is relatively high.

4. Mold electroplating, plating the surface of the mold with a layer of hard chromium. Practice has shown that this method can effectively solve the adhesion of deposits on the surface of the mold. This method is more suitable for mass rubber product molds.
