How to clean the dirt on the rubber, how to wash off the grease stains on the rubber ring

In the injection molding process of rubber products, residues and dirt caused by rubber compounds will adhere to the surface of the precision mold. These rubber residues, charred wax, dirt, oil, and silicone will accumulate on the surface of the mold. In order not to affect the quality of the product, these impurities must be removed.

Conventional cleaning methods.

It is usually necessary to wait until the mold has cooled, disassemble the mold, and then scrub it by hand with cleaning agents, abrasives or polishing pastes, and sometimes even sandblasting or other costly cleaning methods such as grinding and polishing. Manual cleaning is not only inefficient, but often destroys the edges of the cavity.

Ultrasonic cleaning. Ultrasonic cleaning is a fast and effective way to remove dirt from the surface of the mold cavity. A typical cleaning process is:

It is soaked in a hot pre-wash bath, then ultrasonically cleaned in an appropriate cleaning solution, then soaked in a hot spray and finally air-dried. After cleaning, the mold cavity is clean and dust-free, and the mold can be put back into production. The whole cycle takes only 15 minutes.

Cleaning effect. With ultrasonic cleaning, the mold can be cleaned as soon as it comes off the line without having to wait for it to cool. (In fact, hot molds clean faster than cooled molds.)

Ultrasonic cleaning is also effective on sunken areas of the cavity, further improving the quality of the product. The elimination of manual cleaning saves labor and reduces the standby period (no need to wait for the workpiece to cool down). The ultrasonic cleaning method also avoids the abrasion of the mold and the damage to the edge of the mold cavity caused by the abrasive scrubbing method.

Thinner, formally known as thinner or solvent oil, is usually a colorless transparent liquid, commonly known as banana water.

Related Notes:The rubber seal ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with the other ring or washer or forms a narrow labyrinth gap to prevent lubricating oil leakage and foreign object ingress.

There are four ways:

1. Apply toothpaste to the stain and brush it repeatedly with a toothbrush, clean as new.

2. Clean the rubber with kerosene.

3. Wiping with diluted alcohol can also achieve the effect of removal.

4. Pour a little vinegar and soak it in the stain for a while, then wipe it off with a towel, and then use water to remove the taste.

If the cleaning soft glue is only a little slightly stained, then you can go to the supermarket to buy a little bit of rubbing, this kind of thing is a sponge specially used for cleaning, basically all major supermarkets will sell. After buying it, wipe it with water, and the action must be light.

After dyeing, you can also use a strong removal paste, apply a little bit on the dyed area, and then wrap it in plastic wrap for three days after wiping it or add water to dilute the dried liquid, and it takes about 7 to 30 days to remove the staining. If the dyeing is particularly serious, there may also be a possibility that it cannot be removed, usually after using must remember to seal the cleaning soft glue, otherwise the wind and sun may make the cleaning soft rubber become harder and harder, in the process of use, try not to wipe, press the cleaning soft rubber can get a very good cleaning effect.

You can use some alkaline detergents to wash off the all-purpose cleaning soft gel. For example, you can buy a pack of baking soda in the pharmacy, and then put a little bit of it in clean water, and then put the cleaning soft gel in it to wash it after the baking soda has melted, which is also a good method.

If you use the above methods and still can't clean the cleaning soft glue, then it is recommended that you throw away the cleaning soft glue and buy another one, anyway, this kind of thing is very cheap and not particularly expensive. However, in the process of buying, we must pay attention to choosing a better quality, safe and secure, because some cleaning soft gels contain some toxic substances, and regular use may cause some adverse effects on the human body.
