A kind of transactional cards opens greatly the production method of built-in thermoprint metal forming
Technical field
The present invention relates to the producer process modification technology of transaction card, specifically a kind of transactional cards opens greatly the production method of built-in thermoprint metal forming.
Background technology
The increasing market that the cards such as current bank finance industry, Bus Card are produced is large, and within 2012, all banks industry issued volume just reaches 3,200,000,000, and on average everyone holds 2.64 bank cards.Because the design layout of bank card requires higher, restrictive condition is also more, and turnover rate is larger.So the technological requirement of bank card gets more and more, new technology emerges in an endless stream, and the renewal of technique is more and more faster.In order to meet the requirement of high-end customer, a kind of thermoprint has the transactional cards of metallic foil pattern to arise at the historic moment, existing thermoprint processing method is: open first greatly substrate printing, reverse side glued membrane mounts magnetic stripe, by positive and negative large substrate and positive and negative glued membrane superposition spot welding, open greatly lamination again and be die-cut into monolithic, finally carry out individual manual thermoprint metallic foil pattern.This technique exists obvious defect to be exactly flat metal forming of scalding be in card surface, the crocking resistance on surface is poor, and card there will be the problems such as pattern dimness, dry linting, pattern are incomplete after used a period of time.Cause the life-span of product short, the later stage uses unsightly, and the manual thermoprint speed of monolithic is slow, and efficiency is low, and precision is low, affects aesthetic.
Summary of the invention
Object of the present invention is exactly the production method that will solve existing thermoprint metal forming transactional cards, and efficiency is low, and precision is low, and product is easy to wear affects the problems such as outward appearance, provides a kind of transactional cards to open greatly the production method of built-in thermoprint metal forming.
Concrete scheme of the present invention is: a kind of transactional cards opens greatly the production method of built-in thermoprint metal forming, first printed design picture and text on a large front-side substrate, it is characterized in that: send a large hot stamping equipment by the large front-side substrate after printing, thermoprint metallic foil pattern is carried out to multiple the monolithic card faces in whole large simultaneously, then alignment spot welding is carried out by opening greatly positive and negative substrate, mount magnetic stripe in advance at reverse side glued membrane outer surface, then front glued membrane is alignd with front-side substrate simultaneously by reverse side glued membrane and the spot welding of reverse side substrate alignment; The large sheet of base film welded by point opens greatly lamination, and opening greatly sheet of base film by multilayer overlays between laminate, first hot pressing 21 minutes, control temperature 110 degree, pressure is 80bar, after cold pressing 18 minutes, control temperature 20 degree, pressure 100bar, finally carries out die-cut monolithic, makes monolithic card.
Described in the present invention, a large front-side substrate includes 40 monolithic card faces.
In the present invention in the large hot stamping equipment process of use, first card punch is used to accomplish fluently locating hole on the large forward rule limit of a positive and negative substrate, and use the camera positioning device location that equipment carries, to ensure the precision of often opening card, improve hot stamping pattern precision.
After a large thermoprint completes in the present invention, check whether and leak boiling hot or that hot stamping pattern is incomplete situation, then defective part is carried out mark, to facilitate eliminating.
In the present invention, the length and width control errors of die-cut monolithic is at ± 0.1mm.
The present invention adopts a large thermoprint metallic foil pattern, production efficiency is high, accurate positioning, pattern accuracy is high, good product quality, and metallic foil pattern thermoprint is between front-side substrate and front glued membrane, avoid the wearing and tearing in metallic foil pattern use, long service life, good looking appearance, is particularly suitable for manufacturing bank transaction card.
Accompanying drawing explanation
Fig. 1 is the transactional cards sectional schematic diagram that a kind of thermoprint has metallic foil pattern.
In figure: 1-metallic foil pattern, 2-front glued membrane, 3-front-side substrate, 4-reverse side substrate, 5-reverse side glued membrane, 6-magnetic stripe.
Detailed description of the invention
See Fig. 1, this is a kind of magnetic stripe card of thermoprint metallic foil pattern, its production method is: first printed design picture and text on a large front-side substrate 3, particularly: send a large hot stamping equipment by the large front-side substrate 3 after printing, thermoprint metallic foil pattern 1 is carried out to multiple the monolithic card faces in whole large simultaneously, then alignment spot welding is carried out by opening greatly positive and negative substrate 3 and 4, magnetic stripe 6 is mounted in advance at reverse side glued membrane 5 outer surface, then spot welding of simultaneously reverse side glued membrane 5 being alignd with reverse side substrate 4 that front glued membrane 2 is alignd with front-side substrate 3; The large sheet of base film welded by point opens greatly lamination, opening greatly a sheet of base film by multilayer (being generally 120-160 layers) overlays between laminate, first hot pressing 21 minutes, control temperature 110 degree, pressure is 80bar, after cold pressing 18 minutes, control temperature 20 degree, pressure 100bar, finally carries out die-cut monolithic, makes monolithic card.
Described in the present invention produces, a large front-side substrate 3 includes 40 monolithic card faces.
During the present invention produces in the large hot stamping equipment process of use, first card punch is used to accomplish fluently locating hole on the large forward rule limit of a positive and negative substrate, and use the camera positioning device location that equipment carries, to ensure the precision of often opening card, improve hot stamping pattern precision.
After a large thermoprint completes during the present invention produces, check whether and leak boiling hot or that hot stamping pattern is incomplete situation, then defective part is carried out mark, to facilitate eliminating.
During the present invention produces, the length and width control errors of die-cut monolithic is at ± 0.1mm.
