Printing plateIntroduction :
Fujian Sanheng Group Limited production printing plates in 1984, is one of China 's largest specialized production printing plate manufacturing enterprises. High-tech Development Zone, is located in Sanming City, Fujian Province, Sha County Sands Park . Sanheng card printing plates were used: bearing steel , spring steel, chrome steel , oil, steel manufacture four series of nearly a hundred kinds of specifications, from watches printing printing plate 45mm × 50mm × 3mm and electronic printing industry with no rust printing plates 25mm × 70mm × 10mm special small size series , to 400mm × 400mm × 12mm, 320mm × 320mm × 10mm and printing disc Φ330mm × 12mm and other large-sized series. According to customer calls , plans to customize special specifications can fast printing plate production to meet customer requirements at all levels . Sanheng card printing plates reliable quality, stable performance, complete specifications, the steel surface is smooth , high hardness, high wear , rust , in the specialty printing industry enjoys a high reputation , the products sell well in domestic and export various provinces more than a dozen countries and regions, in the fierce market competition, the three permanent card printing plates in technical performance will continue to lead , to welcome new and old customers choose to use.
Manufacturing Process Quality Assurance:
Three permanent license plates are manufactured each undergo a rigorous selection, we choose the most powerful large-scale steel mills as procurement suppliers , requirements must be provided for each batch of steel mills shipped steel products quality assurance , ease of steel in the manufacturing process strictly monitoring to ensure the source of raw material in the manufacture of steel it off to ensure product quality. Each plate rigorous oil quenching and tempering heat treatment process and strict process, to ensure that no cracks and steel deformation processing and printing process use and to ensure that the hardness of steel HRC61 ~ 63, its print life of up to 50 million times above . The surface of each plate were processed , several high -quality steel surface of artificial and natural abrasive material has a fine uniform organizational structure , better graphic quality of the edges , excellent dot reproducibility. Friction of the blade can be reduced to improve the sheet resistance rate , the more important is the copy sensitive adhesive sticking closer contact will effectively reduce the potential for corrosion of the light to improve the copy quality. Steel in the manufacturing process of each process has strict quality inspection checks, clean plate appearance , its flatness and surface finish , fully meet the special printing industry, fine graphic printing requirements , and can be used for various quantities of oil cup printing machine .
Hardness HRC :61-63
1 , bearing steel: has good abrasion resistance, good processing performance, fine uniform organizational structure, good corrosion resistance , better value for money , is the preferred specialty steel printing plate of the printing industry ;
2 , spring steel : a fine uniform organizational structure , compared with the bearing steel, corrosion-resistant steel surface , wear somewhat less certain , cheap ;
3 , chromium steel: Stainless steel is the chromium content of more than 10.5% ( quality parameters ) , and has collectively stainless and acid resistance of a series of iron-based alloys. Usually stainless steel and corrosion in pollution-free air , fresh water , such as water vapor and less corrosive medium , said stainless steel ; corrosion resistance of the steel has a strong corrosive environment in acid, alkali, salt , etc. said acid board. The difference between the alloy composition led to its corrosion resistance is different from the former low degree of alloying , not acid , with only stainless steel , high alloy degree with the latter , and has other alloying elements in addition to chromium compound , and three constant brand chromium stainless steel with both sexual and acid resistance , is to solve the printing plate rusty best material, high manufacturing costs , selling price of your side ;
4 , oil steel : alloy steel with chromium, manganese and vanadium by oil quenching , with hardening and anti-wear performance characteristics , never deformation , good processing performance, organizational structure fine .
Steel can be used in the oil cup-type printing machine
Note : Can be customized a variety of sizes steel
About printing plate rust problems and solutions :
Rusty steel printing plate is mainly determined by the material itself , and the steel chemical elements chromium (Cr) content and the number of speed determines the degree of rusting steel is rust time . Sanheng company uses steel GCr15 bearing steel is a large steel mills Fushun Special Steel production , the amount of chromium (Cr) element is about 1.5% , the quality is guaranteed. A good wear resistance , good processing properties , the fine and uniform structure , good corrosion resistance , the steel sheet is more important is that the price is generally acceptable to the customer . This material has been produced for over 20 years is the preferred steel specialty printing industry printing plates. As for the problem of rusting steel Touchai also occur , especially during the rainy season or be printed with individual customers and solvent inks have a close relationship . We recommend : Customers in the course of using the steel plate to do the maintenance work can be very effective in reducing the probability of rusted steel .
One day after completion of printing of the sheet to be cleaned , cleaning ink residue can not be immersed in a solvent in the cleaning process for too long , the quality of the solvent chosen to meet the requirements ;
2 , after the steel surface to be cleaned immediately dip rust oil , and then wait for the next time you use plastic packaging ;
3 , choose quality inks to meet the requirements , especially thinner, it is very important ;
4 , for some customers because the printed materials are rust problems caused by steel we recommend using chromium steel, chromium steel production Sanheng equivalent of stainless steel : Stainless steel is the chromium content of more than 10.5% ( quality parameters ) , and a stainless steel and collectively, the acid resistance of a series of iron-based alloys. Usually stainless steel and corrosion in pollution-free air , fresh water , such as water vapor and less corrosive medium , said stainless steel ; corrosion resistance of the steel has a strong corrosive environment in acid, alkali, salt , etc. said acid board. The difference between the alloy composition led to its corrosion resistance is different from the former low degree of alloying , not acid , with only stainless steel , high alloy degree with the latter , and has other alloying elements in addition to chromium compound , and three constant brand chromium stainless steel with both sexual and acid resistance , is to solve the printing plate rusty best material, high manufacturing costs , selling price of your side .
Rusty steel sheet involves many problems , particularly in the steel sheet after rust probability maximum appears after printing , the printing plate can not easily rusty all said to be the result of manufacturing companies , and more from the perspective of printing process do maintenance work after printing plate can effectively reduce the incidence of rusting steel .
