Which shape is better for garbage can, round or rectangular?

There are generally two shapes of garbage cans for indoor use – rectangular and cylindrical. Here are some suggestions on which form is more suitable for different scenes and environments: A rectangular garbage can is usually placed directly against the wall or in a corner, which can save more space, especially suitable for the kitchen.

Manufacture Of Stainless Steel Trash Can

 

 

The Stainless steel trash can is widely used in houses, shopping malls, hotels, office buildings and other indoor places. It has the effect of cleaning and decoration and has the material’s advantages. Even if it is placed in the bathroom and other wet areas, it is not rusty but durable. Now let us understand the process performance and see how we process stainless steel trash cans.

The common stainless steel trash cans in the market are 201, 410, 430, and 304 austenitic stainless steel. Austenitic stainless steel is non-magnetic or weakly magnetic, but the microstructure transforms into martensite after cold working. The greater the degree of cold working, the more martensite transformation, and the greater the magnetic properties of the steel. Some parts of stainless steel trash cans, such as the body and the lid, are formed by stamping, with large deformation force and elastic rebound. Therefore, to ensure the accuracy of stamping size and shape requirements, sometimes it is necessary to increase the rest, correction and essential heat treatment. The yield strength of different products is very extra. Therefore, we pay special attention to the load capacity of processing equipment in shearing and forming stainless steel trash cans to ensure the quality of the outer can.

How to make stainless steel trash can

Because the phenomenon of work hardening of stainless steel is very strong, it is easy to cause wrinkles during drawing. Normally, the intermediate annealing should be carried out after each drawing. For the drawing parts with large deformation, the heat treatment to eliminate the internal residual stress should be carried out immediately after the final process. Otherwise, the drawing parts will produce cracks, which is why the cracks in the defective stainless steel waste bin. The heat treatment specification to remove internal stress is heating temperature 350 ~ 450 ℃, and then holding for 1 ~ 3 h at the above temperature. The hot drawing method can reduce work hardening and internal residual stress of the material, improve the tensile deformation ratio and reduce the tensile coefficient. For those parts with complex shapes, we use an advanced hydraulic press, hydraulic press and other equipment to deform them with low drawing speed to get a better effect.

The Historical Changes Of Garbage Bin

Garbage bin changes give significance to human society changes. From a plastic bucket which was neither useful nor attractive became the unique & convenient dustbin, from a private barrel which just only for home use became to the public garbage bin which can be seen everywhere in streets, from a single barrel became to 2-compartments bin with recyclable & unrecyclable function divided. This little thing has been experienced for decades and reflects the deepening of people’s awareness of environmental protection.
