Why aluminum is powder coated

[China Aluminum Network] 1. The higher the purity, the better the corrosion resistance. As we all know, pure aluminum reacts with oxygen in the air and produces a thin layer of dense natural oxide film on the surface of aluminum. The oxide film is generated quickly and thickly, thereby preventing the harmful gases and moisture in the air from corroding, and it plays a protective role;

2, although the corrosion resistance of pure aluminum is good, but the mechanical strength is poor, which restricts the application of aluminum to a certain extent, therefore, people add appropriate amounts of magnesium, copper, zinc and other metals in aluminum to make various types Aluminum alloys and aluminum alloys have high mechanical strength, which greatly increases the mechanical strength of aluminum and greatly expands the application range. Although aluminum alloys have high mechanical strength, they have poorer corrosion resistance than pure aluminum, and therefore may be corroded by oxidation. This requires the powder coating to protect the aluminum alloy profiles. The aluminum alloy is widely used in buildings, doors, windows, curtain walls and other products for many years because of its small specific gravity, easy processing, and large mechanical strength. ,

After powder coating, aluminum profiles have many advantages such as high corrosion resistance, color diversification, and good surface texture, which echoes with different exterior wall coatings to create colorful buildings.

Turning Machine

YT-80 turning machines focus on large enterprises and export customers. Its technology is from Japan. It is automatic line, incorporated with most updated electrical, hydraulic and pneumatic technologies, particularly for high-accuracy, high-productivity and high-reliability turning bearings.Machines can be divided into Outer ring bearing ring machine and Inner ring bearing ring machine.

Automatic Bearing Ring Lathe Machine is a special equipment for turning inner and outer rings of small and medium-sized rolling bearings. The main processing objects are 628-6213 and other models. The assembly line is composed of several single function main machines and various auxiliary machines, which are connected through the slideway to complete the processing of the inner and outer rings of the bearing. It is suitable for the mass production of the inner and outer rings of the rolling bearings. The main engine undertakes the following tasks: inner hole, groove of end face, chamfering of inner and outer rings, separation of inner and outer rings, middle groove and side groove of inner and outer rings. The auxiliary equipment consists of disc feeder, elevator (floor type and bed type), scrap iron crusher, etc. The assembly line integrates mechanical and electrical, pneumatic, hydraulic in one, automatic feeding, processing and cutting, with high degree of automation and short processing cycle. It can flexibly form automatic or semi-automatic assembly lines with different forms and different lengths according to different raw materials and different process requirements of users. The machining accuracy is 0.01mm and the processing technology reaches the domestic advanced level.The machine can choose for double slide turning machine and single slide turning machine.
