How to release silicone products?

What to do if the silicone product is not good for release:

In the production process of silicone products, the release of silicone products is the most important step, no matter who more or less will encounter the problem of difficult release, such as the problem of difficult release is very serious, which will seriously affect the production efficiency of silicone products, then how to solve the problem of difficult release?

1. Mold surface treatment
The molding mold of silicone products should be cleaned before the oil pressure molding machine, especially the new mold that has just been unloaded must be sandblasted first.
Choose different detergents for mold.
The sandblasted mold must be heated to a sufficient temperature before placing the mold, and the release agent must be sprayed well before forming.
It is worth noting that the electroplating mold cannot be sandblasted, including resin sand.

2. Spray treatment

In the molding process of silicone products, silicone products do not stick to which side of the mold, nor do they stick to which mold spray, but sometimes it is difficult to stick.

Solution: Spray bottle or other clean water, if you want the product to stick, after spraying, the product will stick where you want it to stick.

3, mold temperature adjustment

The product likes to stick to the lower half of the mold temperature. When the upper mold temperature is 175℃ and the lower mold temperature is 165℃, the product is usually stuck to the lower mold when the mold is lifted.

In short, when the silicone product is difficult to release, do not replace the release agent with a better release agent, in order to facilitate drawing, or increase the use of release agent and frequency of use, too much release agent is easy to cause dirt on the surface of the mold, light will have a certain impact on the appearance of the product, the use of too much release agent will also affect the later screen printing, injection oil adhesion ability. If the above method is not very good, you can consider adding an appropriate amount of internal release agent when preparing the material, but it will increase the additional cost of the product.

How to release silicone products quickly

Silicone manufacturers know that the more modules they can do in a day, the less the corresponding cost. The lower the unit price of silicone sleeve, the more obvious the price advantage. Silicone products factory Begit silicone products, as well as the secrets revealed by customers, silicone sleeves in order to improve the release speed, there are these methods.

1. After refining raw materials, adding release agent and rapid curing agent, the fluidity of silicone casing is stronger, and the original 200-second silicone casing can shorten the molding time by 30% under the same temperature and pressure.

2. The silicone products factory adjusts the temperature and pressure of the machine, usually the higher the temperature, the faster the formation time of the silicone sleeve, but too high the temperature will also produce the situation of explosive edge.

3. Reduce the number of exhaust of the machine, exhaust die up and down, mold speed is slow. If the silicone jacket is not particularly complex, the exhaust can be reduced twice.

4. The silicone products factory should work hard on the mold, open several more discharge cans, and let the rest of the materials come out. If the number of silicone sleeve is large, you can choose to open several more holes on the large mold to increase the output of each mold.
