How to avoid bubbles in liquid silicone embossing process?

 Treatment of bubbles in liquid silicone embossing process

In the mass production of silicone embossing customer groups,More than one or two customer feedback in the silicone embossed production,The vacuum pumping time and the vacuum intensity are not grasped in the vacuum pumping process,Will lead to the emergence of bubbles is one of the obvious quality problems.Therefore, in order to facilitate customers better use of our silicone embossing machine to make better products,Many experiments have proved that we specially introduce silica gel embossing vacuum machine,Because the silica gel embossing vacuum machine can be programmed to set a good time to grasp the strength of the extraction, reduce the source of bubbles, reduce bad products.

After the vacuum extraction is completed, the material is filled into the mold,In the filling process, we must bear in mind,Not to fill out less is to waste material less,Fill in some excess silicone material，The extra silica gel can be recycled，Because before the heat pressure is solidified, liquid silica gel flows，This will effectively reduce the gap between the mold and the product,To make the product more perfect, reduce the existence of bubbles.

The third problem is mold cleaning not cleaning,In cleaning the mold, pay attention to the method, try to use soft fabric gently scrub,So as not to cause mold deformation.

The above three points are the main reason for the formation of bubbles,Of course there are other reasons this will not say one by one.If you have what happened in production issues timely communication with our company,We will give you a solution as soon as possible.We will also often study and grope for some new ways and means,In order to improve production efficiency, and make better results,Let our customers get more satisfactory production, and then your buyers get more perfect products.
