3.QPQ

QPQ is the abbreviation of Quench-Polish-Quench, which means that ferrous metal parts are placed in two salt baths of different properties, and multiple elements are infiltrated into the metal surface to form a composite infiltration layer, thereby achieving the purpose of surface modification of parts. It has good wear resistance, fatigue resistance, corrosion resistance, and small deformation. This process is applicable to both steel materials.
(Note: Stainless steel products cannot be blackened, and can only be blackened through QPQ)

4.Electroplating

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

 

5.Silk screen printing

Silk screen printing refers to the transfer of ink patterns onto products through a screen. The color of the ink can be customized according to customer needs.

 

6.Wire drawing

Wire drawing is a surface treatment method that uses a flat-pressed sand belt and a non-woven roller brush to form lines on the surface of the workpiece to achieve a decorative effect. Surface wire drawing can reflect the texture of metal materials and is becoming more and more popular in modern life. It is widely used in the shells of mobile phones, computers, monitors, furniture, electrical appliances, etc.

7.Laser engraving

Laser engraving, also known as laser engraving or laser marking, is a surface treatment process based on optical principles to form a logo or pattern on the product.

8.Blackening

Blackening is also called bluing. The principle is to immerse the product in a strong oxidizing chemical solution to produce an oxide film on the metal surface to isolate the air and achieve the purpose of rust prevention. This process is applicable to both steel materials.

9.Passivation

Passivation, also known as chromate treatment, is a pickling process that removes surface oil, rust, and oxides through immersion or ultrasonic cleaning. Through the chemical reaction of the passivation solution, it prevents corrosion and prolongs rust. The color of the passivation film will change with different materials. Passivation will not increase the thickness of the product, so there is no need to worry about it affecting the accuracy of the product.

10.Powder spraying and painting

Painting and powder spraying are two common surface treatments in hardware parts spraying. They are the most commonly used surface treatments for precision parts, small batch customization, etc.

11.Sandblasting

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.

12.Teflon spraying

Also known as Teflon spraying, it is a very unique surface treatment, it has excellent anti-stickiness, non-stickiness, high temperature resistance, low friction, high hardness, non-wetting, high chemical resistance and other characteristics.
