The bottom bead is optimal under the current (2012) technical conditions because the overall Stainless Steel Sink generally require high temperature annealing, typically temperatures above 1200 degrees, and the treated stainless steel sinks are naturally steel. Weakening, the hardness of the stainless steel sink will certainly be reduced, and this is one of them.
Second, the thickness of the steel plate generally used is 0.8-1.0mm. If it exceeds this thickness, it can be said that even a 500-ton hydraulic press is useless. Therefore, from this point of view, the thickness of the overall stretched pot is difficult to guarantee. Thirdly, in terms of edge treatment, the overall stretched pots are generally single-layered and flanging. On the one hand, it is possible to cut the hands of the installation workers. The most important thing is that there is no ""reinforcement ribs", and the carrying weight is not good enough. At the same time, it is also difficult to seal the water; fourth, the overall stretch may be difficult to flatten the panel.
Process defects. For the solder pot, the hardest thing to do is to ensure that the surface of the pot is flat. If it can be guaranteed, then it is really the best way, because: it uses the same material as the overall tensile, it can also solve the one-stretch pull Extend the problem, but many on the market are difficult to perfect.
For bottom welding, personally feel that it is the most mature and best molding technology. The premise is that it must be CNC welding. Manually welded pots, it is easy to occur uneven welding, the actual is the traces of continuous repair welding. The most advanced numerical control welding technology is cited, and numerical control welding avoids the phenomenon of false welding and missing welding.
Reminder. Remind everyone that when choosing pots, you can take a serious look at whether or not there is a thin seam at the welding site. If there is, then it must be a virtual weld. Then, after a long period of time, it will become filthy and will leak. Everyone: When you buy a stainless steel sink, you can use your hand to touch the wall of the pot to see if there is a bulge. The high-grade Stainless Steel Kitchen Sink with Drainboard will not have a bulge; once again, remind everyone to buy a stretch stainless steel sink, pay attention to the thickness and tolerance of the stainless steel sink.
