The effect on product quality, perfect binding Experience

Perfect binding technology in the rapid development of printing books, but there also followed a number of binding quality, a number of manufacturers to the operators without technical training, he was the blind production, leading to products emerging out pages Binding , loose pages, including side, the back uneven, bubble, bear and other fault phenomenon, which the swap pages and loose the most obvious and great inconvenience to readers. Then, the factors affecting product quality Binding What exactly do?

Print Network HC As the perfect binding process has less process, processing speed, short production cycle, quality and stability, low labor intensity and the binding characteristics of beauty, is increasingly being recognized by customers and consumers, and gradually become the main form of modern binding . Perfect Binding books and printing technology in rapid development, but there also followed a number of binding quality, a number of manufacturers to the operators without technical training, he was the blind production, resulting in Binding products emerging out pages, loose pages , including bias, the back uneven, bubbles, bear and other failure phenomena, which the swap pages and loose the most obvious and great inconvenience to readers. Then, the factors affecting product quality Binding What exactly do? Some experiences about the author below.

Staff technical quality and device status

First of all, perfect binding quality is good or bad, with the technical level of operators has a direct relationship. Pre-service, manufacturers need to conduct technical training on the operator to understand the performance of bookbinder, operation order, maintain the principle and the corresponding number of solutions, otherwise it will improve the quality of a product may cause some difficulty. Therefore, to increase the first-line personnel to new equipment, new technology, new products, new processes to understand and improve their technical quality and comprehensive ability.

Second, the equipment is to improve the operability of the basic guarantee of product quality Binding. In the production process, equipment, the event of a failure, should be immediately removed, the machine is always in good running condition. Binding Process of supporting measures

Print the value of the finished product depends on the final binding to the embodiment of the process quality, process technology must be bound to obey the requirements to play the perfect binding process can be most effective. First of all, the cover Design Binding products to meet the technical requirements. Make-up time, to cover the day head to the feet to stay out of 5 ~ 10mm increase in knife, to prevent cover short, the book block long delay caused by gum and a lot of downtime issues. In addition, the cover of the paper cutting precision and perfect binding quality may also have important relationships, cutting out the paper size to be consistent, side and side angle to become 90 °, the upper and lower blade to vertical, cut the cover of Time size should be uniform, may not have the slightest ambiguity. So, paper cutting is good or bad, is the cover printing, cutting the basis of accuracy, is also one of the most critical link.

In addition, perfect binding books out pages and loose a significant part of the problem related with the folding, folding a set too large, folder page hit page is not in place, are caused by out page and loose because . So, whether machine or hand-folding folding, four-fold gas must be notched up in order to avoid a set; a folding or a single page with sticky pages of the best ways to solve, so as to ensure pages do not appear out phenomenon. Core thick book, paper, books and quantitative large, gum layer is too thin out pages, loose pages of the main reasons. If the mill back too deep (more than 3mm), will result in pre-open mouth does not cut, the phenomenon is reduced page. The call back operators strictly controlled milling depth, rotation within the page control in 3mm, Ping Zhang Pages control in 2.5mm or less, a set of folding is less than 1.5mm. When the book is too thick core back slot to increase the depth of milling, gum increased the thickness of about 1.2 ~ 1.5mm, so the back is not easily broken and out of pages.

Proper use of hot melt adhesive

Disk now used bookbinder EVA hot melt adhesive, gum control the temperature generally between 160 ~ 180 , adhesive side of the temperature control in general between 90 ~ 110 before using warm 2 hours, it has good mobility.

Hot melt adhesive temperature must be strictly within the scope of use can not be too high nor too low. Temperature is too high, the flow of hot melt adhesive, permeability increases, but viscosity and strength will drop, affecting the bond strength books; the temperature is too low, hot melt viscosity will increase, mobility and permeability will be affected Hot melt adhesive will thicken, become brittle and the adhesive ineffective. Books should use some quality art paper better, stronger hot melt viscosity, because of its high tensile strength, better bonding results.
