The rubber roller is a roll-shaped product made of metal or other materials as the core and covered with rubber by vulcanization.According to the use, it can be divided into: papermaking rubber roller, printing and dyeing rubber roller, printing rubberroller, grain hulling rubber roller, metallurgical rubber roller and mimeograph rubber roller, etc.

1) Base roller:

Base roller is 304 or 201stainless steel, #45steel or #5 aluminum seamless pipe .We adopt a reasonable thickness base roller according to customer’s drawing. Some manufacturers reduce the thickness of the steel pipe to make price lower but such roller can’t meet standards.

2）Rubber:

Rubber all imported from Germany or the US and we mix them in our factory.We use winding technical. We casting the rubber on thebase roller layer by layer and then vulcanize it to make the green rubber into mature rubber. While other manufacturers are using sheet coating technical,and the rubber is cold in processing and will cause adhesion problems easily.

3）Dynamic balancing:

Before installing shaft head, we will do dynamic balancing test twice for each rubber roller,which will ensure the using effect.

4) Hot charging technicals:

Adopt hot charging technicals to install the shaft head, and then weld after contraction to ensure the quality of shaftinstallation.While other supplier are welding the shaft head directly.

5) Hardness testing by making small sample

We will make a small sample before the official production, after vulcanization, 24 hours later we will check the hardness, color,and Impurity situation. We will control the hardness tolerance within 3degree. If it is not qualified we will change the formulated immediately and to make the sample again till all the data reach the customer’s request.

6) Quality control Department

Using all-imported laser tester to ensure that the geometric size and the accuracy of the roller can reach 0.01 mm;

1. NBR rubber roller

Can be used as printing roller, food industry rubber roller, dyeing roller in textile printing in dustry and the soft rubberroller for contacting solvent and so on.

2.Silicone roller

Can be used in fabric heat setting, plastic heat setting embossing, calendering, photocopying and so on.

3.Polyurethane rubber

It has outstanding tensile strength wear resistance and crack resistance and good resistance to a variety of solvents.

4. Neoprene roller

Suitable for the soft printing roller, gravure printing roller and so on.
