Embodiment

Below by specific embodiment, the present invention is further illustrated.

Basic operation is as follows:

1.1 patterns and the film make

Because the product of meticulous etching has entered the category of the artwork, so intact the combining of condition that the factor of many to moulding, layout, color, particularly light reflection etc. artistic effects and production technology should be allowed during drawing.The extra fine wire bar of hollow out product should more than 1.2 of base material thickness times; The extra fine wire bar interval of surface etching product should at about 0.16mm, and this black line and ratio in vain in the middle of 0.16mm are made 1: 3,2: 2,2: 1 depending on reflectance is different.The positive and negative film surrounding of two-sided etching products should have clearly aims at cross curve accurately, and positive and negative two sheets all nearly base materials of key medicine film note.

The 1.2 2400 revs/min of buffing in sheet material process (for copper coin) sheet material front, reach mirror effect, then go cured, oil removing, cleaning, dried for standby.

1.3 wire mark photo-imaging photoresists

Because pattern-making is superfine.Cannot repair after development, the photoresists therefore chosen are particularly important.My company selects the anti-corrosion ink of Gao Shi (coates) photo-imaging, and with the full version printing of 200 order silk screens under gold-tinted or ruddiness, first time prints polished surface, 100 DEG C are dried 15 minutes, second time back up, then dry 30 minutes with 100 DEG C, to be cooled, surface is tack-free, can expose.

1.4 exposure

Air-breathing smile version machine exposes.Time shutter 20-100 second, not etc. lines were thinlessser, and the time shutter is longer, otherwise then short.

1.5 development

With the development of 3-5% aqueous sodium carbonate, water temperature is at about 50 DEG C, and after the bubble several seconds, aqueous solution brushed gently with soft wool brush, then clear water rinsing secondary, reaches till not having removing residual glue completely.Wet copper coin is directly etched, row etching again after also can drying.

1.6 etching

Available two kinds of methods etch:

A, electrolytic process: electric current 15-50A, voltage 3-5V, electrolytic solution: 20% ammonium chloride, 20% potassium chloride, 20% sulfuric acid, anode titanium plate.Remove in time in electrolytic process anode float stay cathode copper, with ensure electric current normal through.

B, tri-chlorination iron processes: select purer ferric trichloride to soak 30 Podbielniak degree solution, Flow Corrosion.The same space of a whole page will reach depth different-effect, after first time reaches either shallow requirement, and clean surface, dries.Coat (stamping) common etch resistant ink reaching either shallow etching place, then row second etch.

1.7 membrane removal

By etch complete copper coin be placed in water, NaOH, potassium cyanide 30: 1: 0.1 solution heat to 70 DEG C of membrane removals, cleaning bright dipping.

1.8 plating

Copper plate patterns after membrane removal is very bright, very carefully, need not go again and plate bright copper, can directly carry out nickel plating 40-90 second, then go gold-plated, silver-plated.

2 wire mark colored platings

It is adopt manual coloring in support painted two methods with electrophoresis that plating is in the past produced painted.Color in by hand, speed is slow, low precision, and the smooth finish in as easy as rolling off a log damage non-staining face.Electrophoresis colour: (1) will have specialized equipment, (2) will have certain batch, and (3) are by the restriction of colored paint color dullness.Wire mark colored plating is exactly the pattern and word screen printing method that need colouring to be imprinted on by shades of colour on the sheet metal that needs to electroplate.And then row plating, satisfactorily solve the defect of above two kinds of methods.

---wire mark colouring (red ink paste used for seals baking look)---finally dries 150 DEG C of-1.5 hours---nickel plating---gold-plated (silver) to base material polished and cleaned

The technological process of wire mark colored plating is: concrete operations are as follows:

2.1 cleaning base materials

Attention: A: then base material is taken out to before print oven dry from polishing, cleaning from water, and overall process will be worn gloves and operate, and definitely directly can not contact with hand.B, that base material polished and cleaned will reach surface is all hydrophilic, without any speckle after air-dry.

2.2 make wire mark version

With 300 order terylene silk net plate-making, gap bridge will be got well, and cull thoroughly will wash down and not have trachoma and broken string.

2.3 choose screen printing ink

Select acidproof, alkaline-resisting, heatproof, strong covering power wire netting ink, our company selects NSK 1300# ink.

2.4 meticulous wire marks are thoroughly dried

Select glue on the low side in hardness to scrape multiple black wire mark, reach layer of ink thick and even, broken string and trachoma, do not printed baking of the same colour (100 DEG C, 10 minutes) of the same colour, printed oven dry 150 DEG C for the last time, 1.5 hours.

Oil removing before 2.5 platings

Will be placed in normal temperature degreaser dip 5-10 oil removing second of (heating to 60 DEG C) after oven dry, then whether cleaning checks all hydrophilic without print place.Do not reach requirement, available nylon bruss sub brush is washed, reach hydrophilic till.

2.6 direct nickel plating, gold-plated (silver)

Usual plating is first copper facing, more gold-plated (silver), and copper-plated plating solution is pH value 0-1, and nickel groove and golden groove pH value are 3.8-4.6.Resistance to pH value is not also had at present to be the acid-proof ink of 0-1 in the world.(Seiko 1300# ink is acidproof be pH value be 3), so directly nickel plating, circumvents strong acid and closes, with nickel increase, blast.Although speed is slow, cost is higher, high to value-added coefficient, and the product that batch is little again, impact is little.Electric current 30A during nickel plating, voltage 5V, movable cathode, increasing 0.3mm needs 18-20 minute, needs to increase again, time delay.After cleaning more gold-plated (silver).
