The set of rubber roller wrapping sanding conveyor belt has two parts: the rubber intestine is plastic core or metal with air pump valve, the rubber part is an inflatable seal which is manufactured separately.

Rubber inflatable seal is usually produced by molding technology. Rubber after the heat fixation by metal mold will be vulcanized, passed through the mechanical check phase and will become product if it meets all requirements.

When assembling into a set, the rubber roller is pumped air, wrapped a sanding conveyor belt outside and rotates making the sanding conveyor belt work continuously. Therefore, the rubber is not only pneumatic but also continuously abrasive due to sanding. Commonly, the best rubber material which is chosen is NBR rubber because of two following good factors: appropriate mechanical properties and low cost.

Live printing technology on the arc of the glass bulbs requires the silicone rubber layer to be very soft and the arc of the rubber to be very accurate. Silicone rubber should meet the requirements of tear resistance, good elasticity so that the ink won't be smeared.

Printing roller prints directly onto the lids of the plastic bottles. Due to the direct printing technology onto the plastic products, the cycles of roller rotation must be very accurate. If the diameter of the roller is small or large, ink will not print in the right cycle, therefore it makes the words or stamps lay on the wrong location.

Because of automatic printing technology, rubber rollers should have the correct diameter. The surface must be absolutely flat and smooth so that the words won't be lost when printing onto the lids.
Rubber roller consists of 2 parts: the iron core and the rubber part. Rollers are typically manufactured in molding technology, the mold is required to be smoothly plated,  no flaws and good ingot positioning

Tablet printing rubber roller, tablet printing silicone roller, rubber roller used in pharmaceutical and cosmetic industry

In production lines of pharmaceutical tablets, silicone roller is used as the roller to get ink printed directly the words onto the tablet. So in addition to food safety requirements, the roller requires to be very smooth and silicone rubber to be very soft, about 28 to 30 shore. In the middle of the silicone roller, there are grooves to ramify the drugs running through conveyor. With this position, it requires high hardness of the silicone.
