Surface treatment

A complete product is not only machined out, but also needs to do a variety of surface treatment to achieve corrosion resistance, wear resistance, beauty, and improve the purpose of service life. We have many years of CNC machining experience, and provide a series of services from machining to surface treatment to assembly, so in addition to numerical control technology, we also have rich experience in surface treatment, the existing surface treatment process covers: Paint, paint, powder, sandblast, shot blasting, anodizing, thick film oxidation, micro arc oxidation, electroplating, electrophoresis, radium carving, screen printing, wire drawing, mirror polishing, dyeing, blackening, CD pattern, etching, highlight, etch, drop glue, etc., for your products.

oxidation

It is an electrolytic oxidation process that converts the surface of the material into a protective film, so that it is not easy to oxidize corrosion, which can extend the life and achieve the appearance of various colors. Commonly used oxidation treatment is divided into: ordinary anodic oxidation, wire drawing oxidation, hard oxidation, thick film oxidation, micro arc oxidation and so on. Materials that can be oxidized are: aluminum alloy, magnesium alloy, titanium alloy, etc.

electroplate

The basic process of electroplating is to immerse the parts in the solution of metal salt as the cathode, the metal plate as the anode, through the current, deposit the required coating on the parts, the suitable electroplating effect will make your products more high-end fashion and bring better market, common electroplating are: copper plating, nickel plating, silver plating, gold plating, chrome plating, zinc plating, tin plating, vacuum plating, etc.

electrophoresis

Electrophoretic technology With the continuous improvement of industrial demand, electrophoretic treatment can be customized with various colors, maintain metal luster and enhance the corrosion resistance of the surface, and have less impact on the accuracy of the product, the unilateral thickness of about 10-25um, thicker can also be customized.

passivation

Passivation is also known as chromate treatment, is a pickling process, by soaking or ultrasonic cleaning can remove the surface oil dirt, rust stains, oxides, through the chemical reaction of passivation liquid, to prevent corrosion and prolong the effect of rust. Passivation film color will change with different materials, passivation will not increase the thickness of the product, do not worry about it will affect the accuracy of the product.

nigrescence

Black is also called blue, the principle of the product is immersed in a strong oxidizing chemical solution, so that the metal surface produces a layer of oxide film, in order to isolate the air, to achieve the purpose of rust prevention, the process is applicable to steel materials.

QPQ

QPQ is the abbreviation of Quench-Polish-Quench, which refers to the black metal parts into two salt bath with different properties, through a variety of elements into the metal surface to form a composite infiltration layer, so as to achieve the purpose of modifying the surface of the parts. It has good wear resistance, fatigue resistance, corrosion resistance and small deformation. The process is applicable to steel materials.

(Note: stainless steel products can not be blackened, only through QPQ to achieve the effect of surface blackening)

Laser carving

Radium carving, also known as laser engraving or laser marking, is a surface treatment process using optical principles to form a LOGO or pattern on the product. Radium carving effect is permanent, high surface quality, suitable for a variety of hardware plastic material products.

Screen printing

Screen printing means that the ink transfers the pattern to the product through the screen plate. The color of the ink can be customized according to the needs of customers. There are 6 colors on the same product, including black, red, blue, yellow, white and green. If you want the screen printing effect to be more lasting, you can also add a layer of UV after the screen printing to extend its life, screen printing is suitable for a variety of hardware and plastic materials, can also be combined with oxidation, painting, powder, electroplating, electrophoresis and other surface treatment.

polishing

Polishing is to make the product beautiful, transparent and protect the surface effect, polishing transparent is your very good choice, hardware products polishing is divided into manual polishing, mechanical polishing, electrolytic polishing. Electrolytic polishing can be used to replace heavy mechanical polishing, especially parts with more complex shapes and parts that are difficult to process with manual polishing methods and mechanical methods. Electrolytic polishing is commonly used in steel, aluminum, copper and other parts.

wire-drawing

Drawing is a surface treatment method that forms lines on the surface of the workpiece by flat pressing sand belt and non-woven roller brush to play a decorative effect. Surface brushed processing can reflect the texture of metal materials, which is more and more popular in modern life and is widely used in mobile phones, computers, monitors, furniture, electrical appliances and other shells.

Powder, spray paint

Spray painting and powder spraying are two very common surface treatments in the spraying of hardware parts, and are the most commonly used surface treatments for precision parts and small batch customization. They can protect the surface from corrosion and rust, and can also achieve beautiful results. Powder and spray paint can be customized with different textures (fine grain, coarse grain, leather grain, etc.), different colors, different gloss (matte, flat, highlight) effect.

sandblast

Sandblasting is one of the commonly used surface treatments for hardware products, it can improve cleanliness and roughness, increase the adhesion and durability between the product and the coating, therefore, many surface treatments choose sandblasting as its pre-treatment, such as: sandblasting + oxidation, sandblasting + electroplating, sandblasting + electrophoresis, sandblasting + powder blasting, sandblasting + paint baking, sandblasting + passivation, etc.

Teflon spray

Also known as Teflon spray, is a very personalized surface treatment, it has superior anti-viscosity, non-viscosity, high temperature resistance, low friction, high hardness, moisture, high chemical resistance and other characteristics, so a wide range of food industry, tableware, kitchenware, paper industry, medical equipment, electronic products and automotive products, chemical equipment, etc. At the same time, it can protect the material from chemical corrosion and extend the service life of the product.

In addition to the above surface treatment, we can also do shot blasting, dyeing, CD pattern, etching, highlight, etch, drop glue, more details please contact us

Questions and answers

1. The difference between powder and spray paint?

>> Powder coating does not contain any solvent, environmental protection and pollution-free, and spray paint contains solvents.

>> The utilization rate of powder coating is high, the utilization rate of powder coating is about 95% or more, and the paint can only be stored for a short time.

>> A wide variety of paint, powder category is relatively less.

>> Spray coating is thicker than spray paint, and the surface effect of spray paint is finer and smoother than that of spray powder.

2. The difference between radium carving and screen printing?

>> Radium engraving processing through the laser beam on the product to form a LOGO and pattern, you can also remove the surface treatment coating of the product, is depressed; Screen printing products transfer the LOGO and pattern to the product through ink adhesion, which is raised.

>> The color of the LOGO and pattern of the radium carving process is the color of the material, and the color of the LOGO and pattern of the screen printing process is the color of the ink, which is customizable;

>> In terms of wear resistance, the effect of radium engraving is more lasting than the effect of screen printing.

>> The cost is not the same, radium carving process is more economical, because it does not need film, and screen printing does.

3. Can stainless steel be blackened?

We received some customer inquiries, stainless steel products can do blackening treatment, our surface treatment engineer's answer is: steel can do blackening treatment, stainless steel can only use QPQ process to achieve the effect of surface black.
