How do you avoid bubbles in liquid silicone embossing process?

Among the customer groups that mass-produce silicone embossing, more than one or two customers have reported that bubbles will always appear during the production of silicone embossing, which is also one of the obvious quality problems.
Therefore, Jinyu Machinery provides you with the following solutions.
1. Vacuuming. During the process, you must master the time and vacuum strength. Jinyu has a vacuum machine specially designed for liquid silicone. It vacuums independently and has two stations. One is specially designed to put in larger silica gel capacity, the other one is specially put into the mold for vacuuming. That is, if the silicone has been put into the mold, but there are still a few bubbles, you can directly put the mold into the vacuum machine for vacuuming.

 

For example, this silicone heat transfer label machine, it is hydrualic press specail for making silicone 3D labels, it is automaticly heat press and cooling presss, and with vucuum system, so the products it makes are bubble-free. 

And this is also a kind of silicone heat transfer label machine, it is with vulcuum also, it just not come with cooling press automaticlly, it need a cooling tabel aside and manually put the mold to cool down.

This is silicone hydrauli molding machine, it also called vulcanizer, special for making silicone products like silcione phone cases, coasters, mats, tags, protect covers, toys, tabelweres, baby products etc. We design tthis machine with vucuum, and also there is one with no vuccum. that could be choose by customs.
