How do you avoid bubbles in liquid silicone embossing process?

April 01, 2024

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.

2. In order to facilitate customers to better use our machines to make better products, many experiments have proved that we specially launched a silicone vacuum machine, and it is automatically equipped with vacuum, and can be programmed to set the time and grasp it properly. The intensity of extraction reduces the source of bubbles and reduces defective products.

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.
