4.Advantage of our rubber roller:

 

A.Raw materials：

1) Base roller

1.      Adopting #304 or #201 stainless steel,#45steel or #5aluminum seamless pipe as the base roller.

2.      Adopting a reasonable thickness base roller according to customer’s drawing.

 

3.      Adopting a strict dynamic balancing test and size inspection before the base roller is put into the next process.

 

2)Rubber:

1.      Our rubber are all imported from Germany or the US and then mix them in our factory.

2.      We only use 100% new material,not use recycled material.

 

3.      The main rubber coating technical we are using is winding technical,you can find the following pictures.

 

B. Production process:

1）Dynamic balancing:

1.Do 3 times of dynamic balancing test in the process of production of each rubber roller to ensure the using effect.

 

2.If it can displayed within 10g on the dynamic balancing device, it is called dynamic balancing. But we can do less than 2g.

2) 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.

3)Testing by making small sample before mass production

1.We will make a small sample before the official production, after vulcanization, 24 hours later we will check the hardness, color, and Impurity situation.

2.We will control the hardness tolerance within 3 degree.

 

3. 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.

4) 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;  

5)  Packaging

 

According to the characteristics of the product for different packaging, such as paper tube, wooden box, iron frame and so on.
