What is a manual sink?
As the name implies, a hand-made sink is a hand-made sink, and there is no fully mechanized production process with numerical control. This is not because the production equipment is underdeveloped, but because of the characteristics of hand-made sinks, which can only be made by hand. Its production process includes welding, grinding, sanding, padding, spraying and sand pushing.
Handmade sinks are usually made of four different types of stainless steel: 20 1 stainless steel (containing nickel 1- 1.5%), 202 stainless steel (containing nickel 5%), 304 stainless steel (containing nickel 8%) and 3 16 stainless steel (containing nickel/kloc). In the workshops of the early handicraft era, because of the low cost, 20 1 stainless steel was basically used. Now in order to upgrade the grade, sus304 stainless steel occupies the position of manual sink. 3 16 stainless steel is particularly expensive, and is generally used in medical precision equipment or as a material for stainless steel implantation in human body.
The hand-made sink is made of 304 stainless steel, which is lead-free and environmentally friendly. The sink is thick, generally above 1 mm, with heavy weight, strong impact resistance and acid and alkali corrosion resistance.
What are the advantages and disadvantages of manual sink?
Manual sink is made of 304 stainless steel plate by bending and welding, which is different from ordinary sink in that there are many places to be welded.
Hand-made water tanks are generally thick, generally around1.3 mm-1.5 mm. This thickness is convenient for welding, and the thickness is uniform, so there will be no phenomenon that the water tank is too thin locally. It is impossible to stretch the sink to this thickness, because the greater the thickness, the greater the punching force required. If it reaches 1.2mm, a 500-ton punch will not help at all. Therefore, from the material point of view, the manual sink will definitely be more wear-resistant.
From the appearance, the hand-made sink is straight up and down, angular and has a stronger texture. At present, the surface treatment of manual sink also includes pearl sand or wire drawing sink, so don't worry about its beauty. But this straight edge has brought us some trouble in cleaning up the residue in the future. Especially the 90 angle is the most difficult to clean. Because most of the edges of the integrated stretching sink are round, it seems far-fetched to make a basin under the table, while the manual sink can easily make a basin under the table, avoiding the phenomenon of water seepage on the table.
Above, Bian Xiao introduced in detail what is a hand-made sink, and explained it from its materials and manufacturing technology. I believe everyone has a clearer understanding of what a hand-made sink is. Bian Xiao also introduced the advantages and disadvantages of hand-made sink from the thickness. In terms of appearance and some details, hand-made sinks are better than other ordinary sinks, so if you need to buy sinks, it is recommended to buy hand-made sinks.
