First, about spraying

1, spraying is the most common surface treatment, both plastic and hardware are applicable. Spraying generally includes oil injection, powder injection, etc., the common is oil injection. Spraying paint is commonly known as paint, paint is composed of resin, pigments, solvents, and other additives. Plastic spraying generally has two paint, the surface of the color is called top paint, the most surface transparent layer is called protective paint.

2. Spray process flow introduction:

1) Early cleaning. Such as electrostatic dust removal, etc.

2) Spray the top coat. The top paint is usually the color of the surface.

3) Dry the face paint. Divided into room temperature natural drying, special oven drying.

4) Cooling the finish coat. Special oven drying needs cooling.

5) Spray it with protective paint. Protective paint is generally used to protect the top paint, mostly transparent paint.

6) Curing the protective paint.

7) QC inspection. Check that the requirements are met.

3. Rubber oil

Rubber oil, also known as elastic paint, feel paint, rubber oil is a double component high elastic feel paint, sprayed with the paint has a special soft touch and high elastic surface feel. The defect of rubber oil is high cost, durable general, easy to fall off for a long time. Rubber oil is widely used in communication products, audio-visual products, MP3, mobile phone shell, decorations, recreational supplies, game controller, beauty equipment, etc.

4. UV paint

3) vacuum coating surface is not wear-resistant, needs to be protected by UV, water plating is generally not UV.

4. About IMD / mold decoration technology

1. Chinese name of IMD: interior decoration technology, also known as free coating technology. English name: In-MoldDecoration, IMD is the international popular surface decoration technology, the surface hardening transparent film, the middle printing pattern layer, the back injection layer, ink in the middle, can make the product friction, prevent the surface is scratched, and can maintain the bright color for a long time is not easy to fade.

IMD interior decoration is a relatively new automated production process, IMD can reduce production steps and dismantling components compared to the conventional process, So fast production saves time and cost, It also has an improved quality, Increase image complexity and improve product durability advantages, IMD) is currently the most efficient method, It is printed on the surface of the film, high-pressure molding, cutting, Finally, combined with plastic molding, Exemption of secondary operation procedures and their human working hours, Especially in the need to backlight, multi-curved surface, imitation metal, wire processing, logical light lines, rib interference... printing and painting process can not be processed, It is also the time to use the IMD process.

IMD mold interior decoration can replace many traditional manufacturing processes, such as thermal transfer printing, spraying, printing, electroplating and other exterior decoration methods. In particular, a variety of color images, backlight and other related products.

Of course, it should be noted here: not all plastic surface decoration can be replaced by IMD process, IMD also has material technical bottlenecks (such as the inverse relationship between hardness and stretching, positioning accuracy, shape and convex spacing, drawing slope, etc.) specific products to provide 3D map file for professional engineers to analyze.

2, IMD contains IML, IMF, and IMR

IML: IN MOLDING LABEL (is to put the printed flush good decorative sheet into the injection mold, and then the resin injection in the back of the molding sheet ink layer, so that the resin and sheet synthesis integrated curing molding technology. Printed flush inside the plastic shot.) (No stretch, small curved surface, used for 2D products);

IMF: IN MOLDING FILM (roughly the same as IML but mainly used for 3D processing based on IML. Printed molding flush inside the plastic shot. Note: The molding is mostly PC vacuum high-pressure molding.) (Suitable for high tensile products, 3D products);

IMR: IN MOLDING ROLLER (focus on the separation layer on the glue. PET FILM Printing from the agent printing ink printing in the plastic ink and plastic and then open the mold glue will automatically release from the ink. Japan is called hot transfer writing or hot transfer printing. This machine is a ROLL TOROLL and a CCD computer. His sheet custom cycle is relatively long, the mold cost is relatively high, the technology is not output, only in Japan.) (Remove the product surface film, leaving only the ink on the surface of the product.）；

2, printing (padprinting) process is very simple, using steel (or copper, thermoplastic) gravure, the use of silicone rubber material made of curved printing head, the ink on the surface of the printing head, and then press the object surface to be able to print the text, patterns, etc.

3. The difference between imprinting and screen printing:

1) Imprinting is suitable for irregular surface and curved radian, while screen printing is suitable for plane and small arc surface.

2) Imprinting to sun steel plate, silk printing with mesh plate.

3) Imprinting is transfer, screen printing is direct leakage.

4) The mechanical equipment used by the two is very different.

Seven, about the water transfer printing

1, water transfer, commonly known as water decal, refers to the patterns and patterns on the water-soluble film are transferred to the substrate through the pressure of water.

2. Comparison between water transfer printing and IML:

IML process: the pattern position is accurate, the pattern package edge can be optional (chamfered or inverted bag), the pattern effect is variable, never fade.

Water transfer printing: the pattern position is not accurate, the pattern package edge is limited, the pattern effect is limited (the special printing effect can not be done), will fade.

Eight, about the hot transfer printing

1, hot transfer is a new printing technology, from foreign introduced but more than 10 years. The process printing method is divided into two parts: transfer film printing and transfer printing, transfer film printing network printing (resolution of 300 dpi), the pattern printed on the film surface, printing pattern is rich, bright color, varied, small color difference, good reproducibility, can achieve the requirements of the design, and suitable for mass production; transfer film on the product surface, after forming the ink layer and product surface into one, lifelike and beautiful, greatly improve the grade of the product. However, due to the high technical content of this process, many materials need to be imported.

Thermal transfer film can be designed and produced according to the requirements of customers, and the pattern can be transferred to the surface of the workpiece through hot pressure to improve the product grade. Thermal transfer printing process is widely used in plastics, cosmetics, toys, electrical appliances, building materials, gifts, food packaging, stationery and other industries.

Nine, about the thermal sublimation of the dye printing、

1. This method is especially created for the use of the surface decoration of prefabricated products and three-dimensional plastic products. This method can not provide scratch resistance and other protection on the surface of the product, on the contrary, it can provide not easy to fade, even if the scratched can still see the printing quality of beautiful colors. Different from web printing or painting, the color saturation presented by this method is much higher than other coloring methods.

2. The dye used in thermal sublimation can penetrate into the surface of about 20-30 microns of the material, so even if the surface is brushed or scratched, its color can be maintained very bright. This method is also widely used in a variety of products, including SONY's laptop VAIO. This computer is using this way to do different colors and patterns of the surface treatment, so that this product is more distinctive and personalized.

Ten, about baking paint

2, the difference between baking paint and ordinary paint: after baking paint, let the tightness of the paint layer is stronger, not easy to fall off, and the paint film is uniform, full of color.

3, piano paint process, is a kind of paint process, its process is very complex, first, need to apply putty on the board, as the bottom of paint; the putty leveling for putty dry, polishing and smooth; and then repeatedly spray 3-5 times primer, each spraying, to use water sandpaper and polishing; finally, spray 1-3 times of bright paint, and then use high temperature baking, make the paint layer curing, primer for curing transparent paint thickness about 0.5mm-1.5mm, even if the iron cup temperature 60-80 degrees high temperature on its surface will not have any problem!

Eleven, about oxidation

1, oxidation refers to the chemical reaction between the object and the oxygen in the air, called the oxidation reaction, which is a natural phenomenon. The oxidation described here refers to the surface treatment process of hardware products, which is a kind of electrical oxidation reaction through artificial control, with more applied anodic oxidation.

2, the process: alkali washing- -washing- -bleaching- -washing- -activation- -washing- -aluminum oxidation- -washing- -dyeing- -washing- -sealing- -washing- -drying- -quality inspection- -storage.

3, the role of oxidation: protective, decorative, can be colored, insulation, improve the binding force with organic coating, improve the binding force with inorganic overlay.

4, secondary oxidation: in the surface of the product shielding or anaerobic way, let the product oxidation twice, called secondary oxidation.

1) Different colors on the same product two colors can be close or different.

2) Production of the LOGO protruding from the product surface. The LOGO protruding from the surface of the product can be stamped molding or obtained by secondary oxidation.

12, about mechanical wire drawing

1, mechanical drawing is through the mechanical machining process on the surface of the product friction traces of the process. Mechanical drawing has straight lines, disorderly lines, threads, ripples, and sun lines.

2. Materials adapted for mechanical drawing:

1) Mechanical wire drawing belongs to the surface treatment process of hardware products.

2) Plastic products can not be directly mechanical drawing, plastic products after water plating can also achieve grain through mechanical drawing, but the coating is not too thin, otherwise it is easy to pull bad.

3) Among metal materials, the most common mechanical drawing is aluminum and stainless steel. Because the surface hardness and strength of aluminum are lower than that of stainless steel, the drawing effect of mechanical drawing is better than that of stainless steel.

4) Other hardware products.

Thirteen, about the radium carving

1, radium carving, also known as laser carving or laser marking, is a process of surface treatment with optical principles.

2, radium carving application place: radium carving almost adapt to all materials, hardware, plastic is commonly used field.

3) Some lines with obvious depth on the surface of hardware products.

Sixteen, about sandblasting

Sandblasting is a process of cleaning and coarsening the matrix surface using the impact effect of high-speed sand flow. Using the compressed air to form a high-speed jet beam will spray (copper ore, quartz sand, diamond sand, iron sand, Hainan sand) to the surface of the surface of the surface of the appearance or shape of the impact of the abrasive, the surface of the workpiece get cleanliness and different roughness, improve the mechanical properties of the workpiece surface, thus improve the fatigue resistance of the workpiece, increase the adhesion between it and the coating, prolong the durability of the coating, is also beneficial to the flow of paint and decoration.

2. Application scope of sandblasting

1) workpiece coating, work bonding pretreatment blasting can put the workpiece surface rust skin all dirt removal, and establish the basis of the workpiece surface a very important formula (i. e., usually so-called wool), and can change the abrasive of different grain size, achieve different degree of roughness, greatly improve the combination of workpiece and coating, plating. Or make the adhesive adhesion more firm, better quality.

2) casting wool, heat treatment of workpiece cleaning and polishing sandblasting can clean up casting, heat treatment of workpiece surface of all dirt (such as oxidation, oil residue), and the workpiece surface polishing improve the finish of the workpiece, can make the workpiece with uniform metal color, make the workpiece appearance more beautiful, good-looking.

3) Burr cleaning and surface beautification sandblasting can clean up the small burr on the surface of the workpiece, and make the surface of the workpiece more smooth, eliminate the harm of burr, improve the grade of the workpiece. And sandblasting can make a very small round corner at the junction of the surface of the workpiece, so that the workpiece appears more beautiful, more precise.

4) Improve the mechanical properties of the parts. The mechanical parts are sandblasted, which can produce uniform and subtle concave and convex surface on the surface of the parts, so that the lubricating oil is stored, so as to improve the lubrication conditions, and reduce the noise to improve the service life of the machinery.

5) For some special purpose workpieces, sandblasting can be arbitrarily to achieve different reflective or sublight. Such as stainless steel workpiece, plastic grinding, jade polishing, wooden furniture surface matte, the pattern of frosted glass surface, and the surface of cloth processing, etc.

About corrosion

1, corrosion is corrosion carving, refers to the use of trivia materials in the metal surface pattern or text.

2. Application and production institute of corrosion:

1) The surface treatment process of hardware products.

2) Decorate the surface, can make some more delicate patterns and words on the metal surface.

3) Corrosion processing can produce small holes and grooves.

4) Mold erosion grain bite flower.

About polishing

1, polishing the use of other tools or methods to the surface of the workpiece bright treatment, the main purpose is to get a smooth surface or mirror luster, sometimes also used to eliminate luster (extinction).

2, the commonly used polishing methods have the following several: mechanical polishing, chemical polishing, electrolysis polishing, ultrasonic polishing, fluid polishing, magnetic grinding and polishing.

3. Polishing application place:

1) Generally speaking, any surface needs bright products, to be polished.

2) Plastic products do not directly polish, but to polish the grinding tools.

Nineteen,about bronzing

1, bronzing, commonly known as hot stamping, is a special printing process without ink. Heat the metal plate, apply the foil, and print the gold text or pattern on the print. With the rapid development of hot stamping foil and packaging industry, the application of aluminum stamping is more and more extensive.

2, bronzing process is the use of the principle of thermal pressure transfer, the aluminum layer in aluminum electrochemical printing to the surface of the substrate to form a special metal effect, because the main material used in bronzing is electrochemical aluminum foil, so bronzing is also called electrochemical aluminum hot stamping. Electrochemical aluminum foil is usually made up of multiple layers of material, the substrate is often PE, followed by separation coating, color coating, metal coating (aluminum plating) and glue coating.

The basic process is in the pressure state, namely aluminum stamping plate, substrate pressure, aluminum electrification heating on the heat melt of silicone resin layer and adhesive melting, the heat melting of silicone resin viscosity smaller, and special thermal adhesive viscosity increases after heat melting, makes the aluminum layer and electrochemical aluminum base film stripping at the same time transfer on the substrate. With the pressure removed, the adhesive is quickly cooled and solidified, and the aluminum layer is firmly attached to the substrate to complete a hot stamping process.

3, bronzing mainly has two functions: one is the surface decoration, can improve the added value of the product. The combination of other processing methods such as stamping and stamping technology can show the strong decorative effect of the product: the second is to give the product high anti-counterfeiting performance, such as the use of holographic positioning hot stamping trademark logo. Products after hot stamping pattern is clear, beautiful, bright and dazzling colors, wear-resistant, weather-resistant. At present, the application of bronzing process on the printed cigarette label accounts for more than 85%. In the graphic design, bronzing can play the finishing point and highlight the design theme, especially for the decorative use of trademarks and registered names.

About flocking

Plt is always considered to have a decorative function, but in fact it has many advantages. For example, in jewelry boxes, cosmetics, it is necessary to protect jewelry and cosmetics. It also prevents the effect of condensation and will therefore be used in car packs, boats, or air conditioning systems. Two of the most creative uses I can imagine are the placement of ceramic flatware, and the other is Miele's vacuum cleaner.

21, about the mold outside the decoration

External decoration is often seen as an extension of the molding, rather than another independent process. The outer layer of the mobile phone is covered with cloth, and it seems that it requires exquisite skills to produce special effects, which can be quickly and beautifully produced by the mold exterior decoration. More importantly, it can be made directly on the mold without additional manual post-processing.

22, about self-repair coating

1, this coating has a magical self-repair ability, when the surface has small scratches or fine lines, as long as the heat source, the surface will repair the scar by itself. The principle is to use the increase of fluidity of polymer materials in high temperature environment, so that they will flow towards the increased fluidity after heating. This surface treatment provides an unprecedented protective case for durability.

The protection of some cars is very good, especially when we park in the car in the sun, the coating on the surface will begin to automatically repair the small fine lines or scratches, presenting the most perfect surface.

2. Related applications: In addition to the protection of body parts, may it be applied to the surface of buildings in the future?

23, about the waterproof coating

1, the traditional waterproof coating must be covered with a layer of film, which is not only not beautiful, but also changes the surface characteristics of the object itself. P2I invented the nano waterproof coating, which uses vacuum spattering to attach the polymer waterproof coating to the surface of the workpiece in a confined space at room temperature. Because the thickness of this coating is in nanometers, it is almost imperceptible in appearance. This method is suitable for a variety of materials and geometric shapes, and even some complex shapes, combined with several materials can also be successfully coated with waterproof layer by P2I.

2. Related applications: This technology can provide a waterproof function for electronic products, clothing, shoes, etc. Including zippers of clothing and joints of electronic products can be coated. Others, including laboratory precision instruments and medical equipment, must also be waterproof. For example, laboratory droppers must have a pumping function to prevent liquid attachment, so that the amount of fluid is accurate and intact.
