How Do The Factory Make Stainless Steel Waste Recycling Bins?

Stainless steel waste recycling bins are high-end and beautiful, anti-rust, anti-corrosive, and easy to clean. They can be used in airports,  shopping malls, hotels, office buildings, and other indoor places. And in outdoor areas such as municipal streets, parks, and tourist attractions. They have the effect of cleaning and decoration. It will not rust because of the sunshine or rain, and it is very durable.

How Do The Factory Made stainless steel waste recycling bins

How does the factory make stainless steel waste recycling bins ? Let’s have a look together:

Common stainless steel waste recycling bins on the market are made of materials such as 201, 304. Which is non-magnetic or weakly magnetic.

Some stainless steel waste recycling bin parts, such as doors, spouts, and barrel heads are stamped and formed by molds, which have large deformation forces and considerable elastic rebound. Therefore, to ensure the accuracy requirements of the size and shape of the stamping parts, it is sometimes necessary to increase the adjustment, correction, and necessary heat treatment. The yield strength of different varieties is quite different. Therefore, we need to pay attention to the bearing capacity of the processing equipment in the process of shearing and forming the stainless steel waste bin. 

Because the cold work hardening phenomenon of stainless steel is very strong, wrinkles are hard to avoid during deep drawing. Usually, require intermediate annealing after each drawing; Deep drawing parts with large deformation, after the final drawing. It is necessary to remove the residual heat treatment of internal stress immediately. Otherwise, the drawn parts will have cracks, which is why the cracks in the defective stainless steel waste bin.

The heat treatment specification for internal stress removal is heating temperature 350~450℃. And then holding at the above temperature for 1~3h. The warm drawing method can reduce the work hardening and residual internal stress of the material and increase the degree of drawing deformation; Reduce drawing coefficient. For the deep drawing of stainless steel waste bin parts with complex shapes, you need to choose hydraulic presses, ordinary hydraulic presses. To make them deform at a low drawing speed so that you can get better quality.
