Quality Assurance
1. What if the rolls don't fit?
It's never happened to our rolls before.
Firstly,
we start the production according to the drawings that we've checked
and confirmed with customers, and also when the rolls are in the
process of the final check before delivery, we also check them closely
according to the drawings. so there can't be anything wrong with the
size;
Secondly, we also double check the parameters like the
profiles, height,etc with the customers before we start the production.
so there can't be anything wrong with the parameters either;
Thirdly,
before we start the actual production, our technology department will
check on the drawings carefully and try to confirm all the parameters
with the customers as detailed as possible;
Fourthly, we have high precise checking equipment and procedures, there should be no problem.
Lastly,
if there is a problem with the fitting of our rolls, we will analyze
the results with the customers together, and if it's really our problem
or mistake, we will figure out the problems and take the rolls back to
repair, and of course we will pay for all the costs. We are a company
with great quality, great reputation and also great responsibility, so
the customers don't have to worry about that!
2. How long will the chrome last?
We don't usually guarantee in
time, we guarantee by linearmeters,which is a more professional way. For chrome corrugating rolls, our warranty is 8,000,000 - 10,000,000
linearmeters. It's also up to the quality of the customers'
equipments, paper, and their maintenance of the rolls for sure.
