Different Processing Technology of Cadia Stainless Steel Undermount Kitchen Sink
On the current Stainless Steel Undermount Kitchen Sink market, there are three kinds of stainless steel undermount kitchen sink production process: the overall stamping, seam welding and butt welding three, including seam welding and Welding belongs to the welding basin.

Welding technology is the more common market on the production process. This process is mainly stretched two single-slot tank, and then press a panel, the two tanks welded to the panel, and then grinding process. Process requirements of the tank body stretching equipment is low, generally less than 500 tons of hydraulic equipment can be produced. But its welding and grinding process requirements are relatively high, the general domestic brands usually adopt manual seam welding, artificial grinding, tank and the panel at the junction is more rough, often Weld. Imported brands are CNC welding and CNC grinding, put an end to Weld, polish the seam is very smooth and beautiful.
Overall drawing process, this process is in a piece of material through the combination of mold directly stretched to form two tank body process. The process steps are relatively simple, but the equipment and mold requirements are high, stretching equipment needs more than 600 tons, or even up to 1,000 tons. Whether single slot or double slot, the processing of the tensile is generally divided into two tensile, but the overall stretch in the middle of the two stretching need to be a high-temperature solution treatment. Solution treatment is an important process of stainless steel processing, it is through the austenitic stainless steel to 1050 degrees -1100 degrees, and then a rapid cooling process.
Stainless steel material in the processing or high temperature welding will cause changes in the molecular structure of austenite, increased stress, corrosion resistance decreases. The solution treatment can be a good solution to this problem, the material restored to the original performance, restore its ductility and corrosion resistance.
Butt welding process is to stretch two single slot, the cut flat two sides, and then welded together, and then the overall shape of the panel. Stretching equipment with the same requirements of welding stainless steel undermount kitchen sink, welding equipment selection of argon arc welding.
Three complementary processes, the mainstream of the two have their own unique strengths and weaknesses, in fact, in the design of the stainless steel undermount kitchen sink, some are suitable for seam welding process, and some are suitable for the overall production process for stretching, in fact, for consumers, in fact Is a good choice.
