Metal nameplate manufacturing process

The common metal sign production mainly includes metal flat sun sign, metal screen printing sign, metal corrosion sign, metal plating and metal electroplating nameplate, metal thermal transfer sign and metal sandblasting sign.

Metal sun plate

Metal plate is mainly the use of photosensitive plate way, will be different colors into the film, make it through the development of the method to show on the metal plate, so as to achieve the purpose of a metal plate with an explanatory meaning.

The following is the specific process flow and formula of several kinds of metal sunning signs that we often come into contact with (the process flow of sunning signs) :

1) blanking: the size of wool is generally larger than the size of plate making (5mm or more), flat and smooth board surface, no pits.

2) pretreatment: polishing drawing treatment oxidation and other methods.

3) water seal: the treated board shall be quickly immersed in water after oil removal and film removal, and shall not contact with air.

4) gluing: the configuration of glue liquid.Glue: 200-230g water: 1000ml, boil water for 2 hours to fully dissolve the glue solution, and when the temperature drops to 30-50℃, add photosensitizer (heavy ammonium caseinate) 25-30g, evenly spread the glue solution on the metal plate, dry and set to use.

5) plate printing: SB750 vacuum plate printing machine can be used for photosensitive plate printing, lamp 60-90cm time 40-80 seconds after taking, put in warm water for 1 minute of development into the color solution for dyeing.

6) light preservation: after the brand has been fully dyed, cool and dry, with the brush or spray gun coated with light preservation paint (generally with the eye brand baking paint or non-baking light preservation paint).

Flat sun sign is generally used for indoor supplies, small appliances and non – adverse weather impact equipment.Advantages of plate making process is simple, fast, timely delivery, cost of defective rate and low.The disadvantage is that the sun and rain, easy to fade.No outdoor signs.

Corroded metal plate

Corroded metal plates are also called etched plates.Mainly check the use of mask, etching after processing three steps of processing and made of embossed metal plate or concave metal plate.

Corrosion metal plate manufacturing process:

1) blanking: according to the size required by the drawing (layout size), add no less than 5mm rough edges around.Shearing board USES 720 type pedal type shearing board machine, requirement surface is level off, all round have no profit.

2) surface treatment of metal corrosion sign:

(1) mechanical polishing: a 2.2-4 kw polishing machine is used to mechanically polish the wool, and a 300-350 motor speed of the cloth wheel is generally 2000-3000 RPM.

(2) alkali treatment: cook the metal plate with 10-15% sodium hydroxide in an aqueous solution of 65-85℃ for 10-30 seconds, then wash it with clean water and immerse it in 5% acid solution.

(3) powder treatment method: with a flat brush dipped in the old powder (double powder) will plate uniform cross brush, until the removal of dirt, or remove the effect of oxygen skin, and then with 5% dichromate potassium solution in the closure.

(4) wire-drawing treatment: the metal surface is wire-drawing treated by mechanical or manual methods to achieve the regeneration effect of the metal surface.

Metal screen printing label

Metal screen printing label refers to the use of resin inks, screen printing on the board surface after the early treatment, and then the process of preserving light, film covering can be made into a variety of fine color screen printing metal label.

Metal screen printing technology, is one of the applications of screen printing technology.Now various silk-screen signs have been widely used in the electronics industry and household electrical products, especially in a variety of signs used on the surface of the new decorative technology, it is in a delicate and elegant form, many colorful decorative effects show in front of people, improve the value of goods and competitiveness.

In the production process of metal plate, the decisive role is the screen plate and substrate pretreatment technology and printing points and screen printing ink selection.

Electroplating belongs to nameplate with metal electroforming nameplate

Metal plating and electroplating nameplate is also known as the pile of gold plate, it is the use of screen printing or photosensitive plate making method, the plate coated with film, then the use of electroplating method, let the text and line through pre-plating, casting copper, nickel plating, gold-plated forming a raised pile of gold plate.

It can according to the user’s requirements to complete different patterns and a variety of font text, the product durable not corrosion, not afraid of the rain hit the sun, wear resistance, do not fade.Beautiful and generous colour and lustre is bright-coloured, the design is clear, brightness is good it is all sorts of electronic products, car, household appliance and so on essential car body label stick

Heat transfer metal label

Heat transfer metal plate is the use of surface treatment process to generate a special panel, and then you will design into the color picture with inkjet printing on the paper, by heating the metal plate on the metal plate, made of metal plate.

Production technology of heat transfer metal plate:

Base paper treatment -> printing protective layer -> printing pattern layer -> printing luminous layer -> printing covering layer -> printing adhesive layer -> drying -> packaging.

1) protective layer.

The use of 300 mesh screen printing transparent thermal transfer ink (if the ink viscosity is too large, you can use diluent dilution to the appropriate viscosity), the entire pattern will be printed transparent ink, mainly used to protect the pattern layer, so that the pattern has wear resistance, wash resistance, chemical resistance, and play a role in positioning the pattern.Use natural air or low temperature drying can be.

2) pattern layer.

The pattern layer is printed with thermal transfer color ink, the number of mesh is 300 mesh, according to the actual situation with diluent to adjust the viscosity.The order of printing is mainly based on the color from dark to light.Pay attention to accurate positioning, so as to avoid offset when printing luminous patterns.Use natural air or low temperature drying can be.

3) luminous layer.

Luminescent ink was prepared from luminescent material and transparent thermal transfer ink according to 1:1, and the viscosity was adjusted by diluent.The use of 100 ~ 200 mesh screen printing, the number of times of printing according to the luminance to determine, luminance is high, the number of times of printing, luminance is low, the number of printing, generally printing two times can meet the requirements.Use natural air or low temperature drying can be.

4) covering layer.

As a result of the use of luminous material printing pattern, the design must be printed in the white reflective layer to increase the personalized effect.We use a white thermal transfer ink to print the entire pattern on a screen coated with a printing protection layer.Use natural air or low temperature drying can be.

5) adhesive layer.

Finally with 100 ~ 200 mesh screen printing a hot melt adhesive layer, to ensure that the entire pattern is covered.Mainly used to bond patterns and fabrics.Use natural air or low temperature drying can be.

6) packaging of labels.

The heat transfer mark after drying will be placed flat after packaging with the packaging film.

Sandblasted metal sign

Sandblasting metal sign is to use the computer engraving method, will be engraved post-it stick on the metal plate, the text graphics for sandblasting to form a sand-surface effect, and then carry out oxidation treatment, so that the metal plate appears on the gold effect of the metal sign.

Process flow of sandblasted metal sign:

1) pre-treatment stage of sandblasting process:

The pre-treatment stage of sandblasting process refers to the treatment of the workpiece surface before the workpiece is sprayed or sprayed to protect the coating.The quality of sandblasting pretreatment affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating.If the pretreatment is not good, the corrosion will continue to spread under the coating, making the coating flake off.

After careful cleaning of the surface and generally simple cleaning of the workpiece, with the exposure method coating comparison, life can be 4-5 times.There are many methods of surface cleaning, but the most commonly accepted are: solvent cleaning, pickling, hand tools, power tools.

2) sandblasting process stage:

Sandblasting process is to use compressed air to power form a high-speed injection beam, the spraying material, such as high speed jet to need to deal with the surface, the surface appearance change of components, due to the abrasive effect on impact on the surface of the workpiece and cutting, make get some cleanliness and different roughness of workpiece surface, the workpiece can improve the mechanical properties of the surface.
