Silicone buttons may not encounter such problems, flat silicone products are very easy to release, mainly the release of silicone components. Silicone miscellaneous refers to a class of irregular silicone products in addition to silicone buttons, at present in the entire industry, the name of miscellaneous covers too wide, almost a lot of silicone products are called silicone miscellaneous.

Small partners who often do silicone buttons may not feel the problem of demoulding, silicone keys are mainly more processes, generally out of the product molding, usually will be shipped after screen printing. Although the silicone components are not all need screen printing, but some of the components are the most troublesome problem of silicone products manufacturers, of course, sometimes because the mold is not done, and some may be because of the improper operation of technical personnel, in addition to these problems, there are still a large part of the reason or such silicone components in the shape of the above are strange.

Each set of touch is likely to be a new silicone product. The new product production process is different, so many times it is more challenging. The silicone button is so several types, whether it is technology or process, it is very familiar. The silicone thing is like exploring the existence of another Earth in space. Every planet encountered may be grotesque, so it is more challenging to do silicone accessories, and the manufacturer of silicone accessories is a manufacturer with production technology and strength.

Silicone products are not good how to do

In the production process of silicone products, silicone products molding demoulding is the most critical step, no matter who more or less will encounter the problem of molding difficult demoulding, such as molding difficult demoulding problem is very serious, will seriously affect the production efficiency of silicone products, then in the face of difficult demoulding problems, how to solve? The following introduces several methods of molding difficult to remove mold for reference.

1, mold surface treatment

(1) The molding mold of silicone products should be washed before the oil pressure molding machine, especially the new mold that has just released electricity must be sandblasted first;

(2) Choose different washing sands for male and female molds.

(3) The mold that has just been sand-blasted must be heated to a sufficient temperature before discharge molding, and the release agent must be sprayed before molding.

It is worth noting that the plating mold must not be sandblasted, including resin sand.

2, spray release agent treatment

Silicone products molding, silicone products do not stick to which side of the mold to which side of the mold spray release agent, but sometimes it is not easy to stick.

Solution: Use a spray bottle or other clean water, want the product to stick where to spray, spray and then shape, the product will obediently stick to the place you want 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 it is difficult to release silicone products, do not replace the release agent with better release performance for the sake of convenience, or increase the amount and frequency of release agent, spraying 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 adhesion ability of screen printing and oil injection in the later period. If the effect of the above method is not very good, you can consider adding an appropriate amount of internal release agent to the compound when preparing the material, but it will increase the additional cost of the product.

How to release silicone products quickly

Silica gel manufacturers know that the more modules they can do, the less the corresponding cost. The lower the unit price of the silicone sleeve, the more obvious the price advantage will be. Huayang industry and customers reveal, silicone sleeve in order to improve the speed of release, there are those methods.

1. Silica gel products factory in refining raw materials, adding release agent and rapid vulcanization agent, so that the fluidity of the silicone sleeve is stronger, the original 200 seconds of silicone sleeve, under the same temperature and pressure, can reduce 30% of the molding time.

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

3. Reduce the number of exhaust of the machine, the mold in the exhaust has been up and down and die, the speed is relatively slow. If the silicone sleeve is not particularly complex, it can reduce 2 exhausts.

4. The silicone products factory works hard on the mold and opens several more discharge slots to discharge the remaining materials. If the customer has a large number of silicone sets, the large mold can be selected to open several holes to increase the output of each mold.
