The stainless steel sink brand on the market has various corner treatments, such as flat square corners, rounded corners, thin edges, beveled edges, and floating edges. Among them, the square corner can be used as an above counter basin or as an under counter basin, but because it is a square corner, on the one hand, the viewing angle is not very good, and its carrying weight is not very strong, plus it is in the process of transportation. It is easy to fold the corners, so it is used less; the flanges on the one hand enhance the flatness of the sink, on the other hand, the ribs make the sink load stronger, and have a good water retaining effect, not letting Water flows to the countertops. handmade sink manufacturers like this kind of technology, but they must be double-layered to have an effect. You can see them in the market, many of them are unilateral. At the same time, the sides of the high-grade stainless steel sink are generally flat and have no large curvature.
As far as the sink market is concerned, there are three types of integral stamping (also called integral stretching or joint stretching), seam welding (also called bottom welding) and butt welding, and both seam welding and butt welding belong to the welding basin.
Most of the common on the market is the roll welding process. This process mainly stretches two single-slot tanks, and then presses a panel to weld the two tanks to the panel and then grind it. In the process, the requirements for the tank stretching equipment are low, and the hydraulic equipment of 500 tons or less is generally produced. However, the welding and grinding process requirements are relatively high. Generally, domestic brands usually use manual seam welding, manual grinding, and the joint between the tank and the panel is rough, and there is often a virtual weld. Imported brands use CNC welding and CNC grinding to eliminate the need for virtual welding. The seams after grinding are very flat and beautiful.
The advantages of the seam welding process are:
1. The shape of the sink panel can be diversified, and the input cost of the factory production mold is small (the tank mold can be shared);
2, the sink panel can be drawn raw materials or embossed materials, beautiful and generous. 3. It can make a trough with a small R angle, close to the square, and have more space for use.
The disadvantages of seam welding are:
1. The welding process is harmful to stainless steel, which easily breaks the austenitic molecular structure of stainless steel and reduces corrosion resistance.
2, welding and grinding process requirements are high, ordinary equipment is difficult to compete.
3. Material waste is high and cost is high.
Some of the paints on the market are sprayed with a variety of paints of different colors and materials, claiming to prevent sweat and moisture absorption.
In fact, the main purpose of spraying the coating on the bottom of the sink is to prevent temperature difference condensation, protect the cabinet, and reduce the noise of falling water. Moisture absorption is only a secondary function or a different statement. Quick-frozen foods are placed in the sink or in the wet weather in spring and summer. Because the temperature of the water tank is low, the water vapor will agglomerate the bottom of the basin to form water drops. Dropping water drops can cause the cabinet to get wet. Spraying a suitable coating on the bottom of the tank may reduce or even eliminate the temperature difference and destroy the formation of water droplets. The high-quality coating also has a certain moisture absorption function to protect the cabinet from flooding.
