Extruded Aluminum Shell Aluminum sheet stamping Custom electrical aluminum alloy shell

After more than 20 years of development

Equipment resources of run aluminum products: 13 international advanced aluminum profile extruders, with an annual production capacity of more than 20000 tons; More complete aluminum profile precision processing equipment; More complete aluminum profile oxidation pretreatment equipment, including polishing, wire drawing, sand blasting and other equipment. Environmentally friendly anodizing production line. The total plant area is about 30000 square meters. It is a manufacturer integrating "aluminum profile extrusion, precision machining and surface treatment".

The company is located in the Yangtze River Delta with superior geographical location, leading science and technology and developed transportation in China.

Yurun aluminum products has served thousands of enterprises and is a long-term partner of many state-owned enterprises, multinational corporations and the world's top 500 companies.

Our fields include: automobile industry, aerospace, industrial automation, medical devices, home decoration, home appliance electronics and other industries.

Bending, flanging, drawing and bulging are all called forming. It is estimated that you are talking about drawing.

Aluminum plate is easy to crack during deep drawing. Try to take the following measures to reduce crushing:

(1) Reduce the blank holder force to the limit of no wrinkling

(2) Oil if allowed

(3) Film may be applied if permitted

(4) Use the press with slow running speed, such as hydraulic press

(5) Cut off the excess edge in advance

(6) If you can't, change one drawing to two drawing

5050 thin plate can be used as the lining plate of refrigerator and refrigerator, automobile air pipe, oil pipe and agricultural irrigation pipe; It can also process thick plates, pipes, bars, special-shaped materials and wires

5052 alloy has good formability, corrosion resistance, Candlestick resistance, fatigue strength and medium static strength. It is used to manufacture aircraft fuel tank, oil pipe, sheet metal parts of traffic vehicles and ships, instruments, street lamp supports and rivets, hardware products, etc

Deep drawing process is a stamping processing method that uses the drawing die to press the flat blank into hollow parts with various openings, or process the made open hollow parts into hollow parts with other shapes. Deep drawing is also called drawing.

The deformation process is: with the continuous downward movement of the punch, the outer diameter of the blank left on the end face of the die continues to shrink, the circular blank is gradually pulled into the gap between the punch and the die to form a straight wall, and the material under the punch becomes the bottom of the drawing part. When all the sheets enter the gap between the punch and the die, the drawing process is over, The flat blank becomes a cup-shaped part with a certain diameter and height. Compared with the blanking die, the working part of the drawing punch and die should not have sharp edges, but have a certain fillet, and the unilateral gap between the punch and die is slightly larger than the material thickness.

Cylindrical, stepped, spherical, conical, parabolic and other rotating parts can be made by deep drawing process (see Fig. 2),
