Common surface treatment methods of aluminum profile | Sdql-alu.com

 In order to increase the corrosion resistance and mechanical properties of the aluminum surface, various surface treatment methods shall be carried out for aluminum profile after extrusion.The common surface treatments of industrial aluminum profiles are as follows:


industrial aluminum profiles factory


1. Anodizing: This is a common surface treatment method for industrial aluminum profiles. The principle is to form an oxide film on the surface of the profile. The advantage is that it can increase the profile's anti-corrosion and wear resistance, and has an insulating effect. It is suitable for a variety of industrial production fields and can play an anti-static effect.
2. Electrophoretic painted aluminum profile: Electrophoretic paint film has the advantages of fullness, uniformity, flatness and smoothness. The hardness, adhesion, corrosion resistance, impact performance, and permeability of the electrophoretic paint film are significantly better than other coating processes.

3. Powder spraying: (1) High efficiency and energy saving: Because it is a one-time film formation, it can increase productivity by 30-40% and reduce energy consumption by about 30%. (2) Less pollution: no organic solvent volatilization (excluding toluene, paint and paint) Harmful gases such as xylene) (3) Good film performance: The film thickness can reach 50-80μm at one time, and the comprehensive indicators such as adhesion and corrosion resistance are relatively excellent. (4) Various colors, various colors can be made according to customer requirements.


Shengda Qianliang Aluminum can realize surface treatment methods such as anodizing, polishing, drawing oxidation, small parts oxidation, hard oxidation, electrophoresis, and powder spraying of industrial aluminum profiles.

The Type Of Punch And Force Feeder In Tablet Press Machine

  ***  The type of punch 1. The white material above the mold is polyunsaturate, which can prevent the mold, such as pressed sheet candy material. 2. Gold mold is titanium plated, this is suitable for pressed metal powder by tablet making machine. ***Type of forced feeder: 1.closed forced feeder in  tablet press machine  and open forced feeder are generally more suitable for high-speed press, and is a particle type of material. 2.Open forced feeder of tablet press machine, which is more suitable for dry powder, such as disinfection tablets, washing tablets of this type. Role of the forced feeder: One is to solve the material liquidity problem, if the material liquidity is poor, the forced feeder must be used. Second, when the pressure and filling volume is unstable, loose pieces and fragments are more, and the pressure out of the tablet above the pay more powder, with a forced feeder can also solve this problem. Does the bubbling tablet need a forced feeder? This can not be generalized

T-Slot Cutters  are designed for milling T-slots into different materials. High Speed Steel T-Slot Cutters are designed for milling T-slots into tables and beds of machine tools and similar applications where a good surface finish is required. A vertical slot must be cut first so that neck and shank may enter the cut. T-Slot End Mill is welded with carbide teeth and suitable for the slot milling mainly for milling the workpiece of T-shaped slot or groove of side surface. Staggered Tooth T-Slot End Mill (Chidori Tooth) processing load will be lower than Straight Tooth T-Slot End Mill, as well as more effectively to break and release chip to reduce processing obstruction. Dovetail End Mill is suitable for milling the angle in the groove and clearing the chip. Xiamen Yushang  is a professional supplier in China with 10 years experience devoted to producing kinds of  high quality cutting tools,accept custom service,OEM/ODM are welcome.If you have any sample or drawing,can contact  sales02@
