With the development of science and technology, the society has continued to attach more importance to the material. However, in fact, the market of raw materials is a mixture of good quality and bad quality. Damon Industry also has carried out strict screening of raw material to protect the interests of customers.

In the manufacture of the roller, the quality of the raw material directly affects the performance of the conveying, and raw material is the base of the quality assurance. And many customers only see the similarity of the product on the surface when they buy them. Just like ordinary bags and brand bags, they can be made the same in style, but the hand feeling, hardware accessories and the workmanship are completely different. 

At present, a lot of manufacturers in the roller industry use the following raw materials of the roller due to low cost: 

1. Stainless steel tube stock is the low copper and low nickel material, and is coiled material workpiece of small steel factories; 

2. The carbon tube stock is the base material of hot rolled strip; 

3. The main material of the bearing is not bearing steel, but carbon steel instead. And the thickness of the inner and outer rings of the bearing is unqualified with insufficient materials.

This kind of raw material is low in cost and doesn't seem to be very different on the surface. However, after a long time, the surface of the roller is rusty, the roller has abnormal sound and it is not flexible, which could not be used any time later.

In the selection of product material, Damon Industry is better than domestic products and even higher than foreign counterparts in quality. 

1. The carbon steel tube stock of roller is a special customized linen process. The special process is added in terms of the surface quality, the chemical composition and the rust prevention ability; 

2. The tube stock of stainless steel has been verified. It is not the low copper and low nickel products and it can pass the inspection of component analysis.

3. The roller bearing of Damon Industry is designed for the logistics industry. It could meet the requirements of the special dustproof structure and rotation and bearing life testing of the logistic industry. After the comparison testing of bearing life of domestic and foreign counterparts, Damon Industry roller bearing has a longer bearing life obviously.

As we all know, in manufacturing enterprises, the cost of raw materials accounts for more than 60% of the cost of the product; the brand effect and product quality of the Damon Industry roller make Damon Industry lead in cost performance in the industry. The sales volume increases at least 15% annually. Damon Industry roller is evaluated the "the assured brand" by more than 90% of customers.
