Jinan Jinchangtai Industry And Trade Co., Ltd
We are using #45 steel , #201stainless steel #304stainless steel and 5# aluminum seamless pipe as the base roller.And we are adopting a reasonable thickness base roller according to customer’s drawing.
Based on over 10 years exporting experience in printing lines,our company can provides all kinds of solutions for printing companies.We mainly specialize in supplying printing machines,machinery parts,raw materials,finished printing products and so on.
Mainly used in papermaking, printing and dyeing, printing, grain processing, metallurgy, plastic processing, etc.
A.Excellent oil resistance, alkali resistance, aging resistance and good performance
B.Good heat resistance, high mechanical strength and wear resistance
1) 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.
2) Dynamic balancing:
We will do 3 times of dynamic balancing test in the process of production of each rubber roller,which will ensure the using effect.
In general, If it can displayed within 10g on the dynamic balancing device, it is called dynamic balancing. But we can do less than 2g.
3) Testing by making small sample before mass production
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.
