3.Advantage

(1)Base roller:

We are adopting 304 or 201stainless steel, #45steel or #5 aluminum seamless pipe as the base roller.And we are adopting a reasonable thickness base roller according to customer’s drawing. Some manufacturers will reduce the thickness of the steel pipe in order to get the price advantage.Such roller can’t meet the standards.But we won’t do that.

(2)Rubber:

Our rubber are all imported from Germany or the US and then we mix them in our factory.The main rubber coating technical we are using is winding technical. we casting the rubber on the base 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 shaft installation.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;
