Gloves Production process: How to make nitrile gloves?

Nitrile gloves making machine is a tool used to make nitrile gloves. High efficient, stable operation, you can totally believe in this machine. To make nitrile gloves, you should prepare first the NBR materials. Then, the machine starts to work.

Remark: Any tiny particles remaining on the surface of the hand model may cause holes in the glove, so wash the hand model thoroughly.

1. Soapy water cleaning

That will remove the residue from the last rubber glove.

2. Bleach cleaning

Washing while turning, can increase the cleaning power.

3. Brush cleaning

5. Hanging drip dry

Let the hand mold gradually dry.

6. Chemical water bath

Liquid latex cannot be directly attached to the ceramic, so it is necessary to attach a chemical coating to the surface of the hand mold

7. Coating: Wrap latex

The hand mold is inserted into the warm latex liquid…the chemical coating and the latex will react and turn into a gel.

The molds are coated with materials NBR. The gloves are then heated at a high temperature to form the gloves as they dry.

8. Drying latex

Even when drying in the oven, the hand molds on the assembly line are constantly rotated in order to distribute the entire latex evenly.

After the second dring, the molds will dip into tanks of nitrile rubber.

9. Brush curling

Using multiple angled brushes, rub the latex glove a little at a time, and then gradually roll up each latex glove.

At this point, latex gloves are done. To make it easier to take off the gloves, it’s better to put the gloves under chlorination or polymer coating. Stripping phrase: The gloves will be taken off of the forms.

Not only gloves, but the making of latex condoms is a similar process.

11. Stretching and inflation testing

This is the test every latex glove must pass.

12. Sampling flush test

In a production batch, some latex gloves will be sampled for the water filling test. If there is any unqualified, the entire batch will be discarded. Industrial production is so rigorous.
